35012676 10/2019 Safety Information Important Information NOTICE Read these instructions carefully, and look at the equipment to become familiar with the device before trying to install, operate, service, or maintain it. The following special messages may appear throughout this documentation or on the equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a procedure. 35012676 10/2019 5 PLEASE NOTE Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this material. A qualified person is one who has skills and knowledge related to the construction and operation of electrical equipment and its installation, and has received safety training to recognize and avoid the hazards involved. BEFORE YOU BEGIN Do not use this product on machinery lacking effective point-of-operation guarding. Lack of effective point-of-operation guarding on a machine can result in serious injury to the operator of that machine. WARNING UNGUARDED EQUIPMENT Do not use this software and related automation equipment on equipment which does not have point-of-operation protection. Do not reach into machinery during operation. Failure to follow these instructions can result in death, serious injury, or equipment damage. This automation equipment and related software is used to control a variety of industrial processes. The type or model of automation equipment suitable for each application will vary depending on factors such as the control function required, degree of protection required, production methods, unusual conditions, government regulations, etc. In some applications, more than one processor may be required, as when backup redundancy is needed. Only you, the user, machine builder or system integrator can be aware of all the conditions and factors present during setup, operation, and maintenance of the machine and, therefore, can determine the automation equipment and the related safeties and interlocks which can be properly used. When selecting automation and control equipment and related software for a particular application, you should refer to the applicable local and national standards and regulations. The National Safety Council's Accident Prevention Manual (nationally recognized in the United States of America) also provides much useful information. In some applications, such as packaging machinery, additional operator protection such as pointof-operation guarding must be provided. This is necessary if the operator's hands and other parts of the body are free to enter the pinch points or other hazardous areas and serious injury can occur. Software products alone cannot protect an operator from injury. For this reason the software cannot be substituted for or take the place of point-of-operation protection. 6 35012676 10/2019 Ensure that appropriate safeties and mechanical/electrical interlocks related to point-of-operation protection have been installed and are operational before placing the equipment into service. All interlocks and safeties related to point-of-operation protection must be coordinated with the related automation equipment and software programming. NOTE: Coordination of safeties and mechanical/electrical interlocks for point-of-operation protection is outside the scope of the Function Block Library, System User Guide, or other implementation referenced in this documentation. START-UP AND TEST Before using electrical control and automation equipment for regular operation after installation, the system should be given a start-up test by qualified personnel to verify correct operation of the equipment. It is important that arrangements for such a check be made and that enough time is allowed to perform complete and satisfactory testing. WARNING EQUIPMENT OPERATION HAZARD Verify that all installation and set up procedures have been completed. Before operational tests are performed, remove all blocks or other temporary holding means used for shipment from all component devices. Remove tools, meters, and debris from equipment. Failure to follow these instructions can result in death, serious injury, or equipment damage. Follow all start-up tests recommended in the equipment documentation. Store all equipment documentation for future references. Software testing must be done in both simulated and real environments. Verify that the completed system is free from all short circuits and temporary grounds that are not installed according to local regulations (according to the National Electrical Code in the U.S.A, for instance). If high-potential voltage testing is necessary, follow recommendations in equipment documentation to prevent accidental equipment damage. Before energizing equipment: Remove tools, meters, and debris from equipment. Close the equipment enclosure door. Remove all temporary grounds from incoming power lines. Perform all start-up tests recommended by the manufacturer. 35012676 10/2019 7 OPERATION AND ADJUSTMENTS The following precautions are from the NEMA Standards Publication ICS 7.1-1995 (English version prevails): Regardless of the care exercised in the design and manufacture of equipment or in the selection and ratings of components, there are hazards that can be encountered if such equipment is improperly operated. It is sometimes possible to misadjust the equipment and thus produce unsatisfactory or unsafe operation. Always use the manufacturer's instructions as a guide for functional adjustments. Personnel who have access to these adjustments should be familiar with the equipment manufacturer's instructions and the machinery used with the electrical equipment. Only those operational adjustments actually required by the operator should be accessible to the operator. Access to other controls should be restricted to prevent unauthorized changes in operating characteristics. 8 35012676 10/2019 About the Book At a Glance Document Scope This manual describes the hardware installation of the Modicon M340 PLCs and installation of their main accessories.

Introduction to the Ethernet Port The following illustration shows the processor of the RJ45 Ethernet port: The following illustration shows the pin assignment of the Ethernet port: Introduction to the MAC address The MAC address is located on the front panel of the processor below the processor display panel. 50 35012676 10/2019 Introduction to BMX P34 xxxx Processors Introduction to the Rotary Switches This processor operates as a single node on an Ethernet and possibly other networks. The module must have a unique IP address. The 2 rotary switches on the back of the module provide a simple way to select an IP address: NOTE: Set the arrow firmly into the desired position. If you do not feel the switch click into place, the value of the switch may be incorrect or undetermined. Each rotary switch position that you can use to set a valid IP address is marked on the module. The following information summarizes the valid address settings: device name: for a switch-set device name, select a numeric value from 00 to 159. You can use both switches: On the upper switch (TENS digit), the available settings are 0 to 15 On the lower switch (ONES digit), the available settings are 0 to 9. For example, a BMX P34 2020 processor with the switch setting in the above figure is assigned the DHCP device name BMX_2020_123. The selection on the lower switch of any non-numeric parameter (BOOTP, STORED, CLEAR IP, DISABLED) makes the setting on the upper switch inconsequential. BOOTP: To get an IP address from a BOOTP server, select either of the two BOOTP positions on the bottom switch. STORED: The device uses the application's configured (stored) parameters. CLEAR IP: The device uses the default IP parameters. DISABLED: The device does not respond to communications. The functionality of the rotary switch when used in conjunction with the IP Configuration tab (see Modicon M340 for Ethernet, Communications Modules and Processors, User Manual) is discussed throughout the IP Address chapter (see Modicon M340 for Ethernet, Communications Modules and Processors, User Manual). 35012676 10/2019 51 Introduction to BMX P34 xxxx Processors Switch Labels To assist you in setting the rotary switches to their proper positions, a label is affixed to the right side of the module. The switch settings are described in this table: Upper Switch 0 to 9: Tens value for the device name (0, 10, 20 . . . 90) 10(A) to 15(F): Tens value for the device name (100, 110, 120 . . . 150) Lower Switch 0 to 9: Ones value for the device name (0, 1, 2 . . . 9) Bootp: Set the switch to A or B to receive an IP address from a BOOTP server. Stored: Set the switch to C or D to use the application's configured (stored) parameters. Clear IP: Set the switch to E to use the default IP parameters. Disabled: Set the switch to F to disable communications. 52 35012676 10/2019 Introduction to BMX P34 xxxx Processors BMX P34 xxxxx Processors Catalog Introduction The choice of BMX P34 xxxxx processor is made, primarily, according to its characteristics and possibilities.

This duration is guarantied for a temperature below 45°C (113°F). At a higher temperature this duration is reduced. No maintenance is requested for a real-time clock back up. Current Date and Time The processor updates the current date and time in the system words %SW49...%SW53 and %SW70. This data is in BCD (Binary Coded Decimal). System Word %SW49 Most Significant Byte 00 %SW50 %SW51 %SW52 %SW53 %SW70 Seconds (0 - 59) Hours (0 - 23) Month (1 - 12) Century (0 - 99) Least Significant Byte Days of the week in the range of values 1 - 7 (1 for Monday and 7 for Sunday) 00 Minutes (0 - 59) Days of the month (1 - 31) Year (0 - 99) Week (1 - 52) Accessing the Date and Time You can access the date and time as follows: through the processor debug screen. with the program: Reading system words: %SW49 - %SW53 if the system bit %S50 is at 0, immediate update: writing system words %SW50 to %SW53 if the system bit %S50 is at 1, incremental update: writing the system word %SW59. With this word the date and time can be set field by field from the current value (if the system bit %S59 is at 1), or an overall increment/decrement can be done. The following table shows the function performed by each bit in the word %SW59. Bit Range 0 1 2 3 Function Increments the day of the week Increments the seconds Increments the minutes Increments the hours 54 35012676 10/2019 Introduction to BMX P34 xxxx Processors Bit Range 4 5 6 7 8 9 10 11 12 13 14 15 Function Increments the days Increments the months Increments the years Increments the centuries Decrements the day of the week Decrements the seconds Decrements the minutes Decrements the hours Decrements the days Decrements the months Decrements the years Decrements the centuries NOTE: The function is performed when the corresponding bit %S59 is at 1. NOTE: The processor does not automatically manage Daylight Savings Time. Date and Time of the Last Application Shutdown The date and time of the last application shutdown are in BCD in the system words %SW54 - %SW58.

Step 1 2 3 4 5 6 7 8 9 Description Put the PLC in STOP. Set bit %S65 to 1 and check that the CARDAC LED is off. Remove the currently used memory card, which includes the old application. Insert the master memory card in the the processor. Press the RESET button on the power supply. Result: the new application is transferd to internal RAM. Remove the master memory card. Insert the memory card with the old application in the the processor. Do a backup command. Put the PLC in RUN mode. Protect an Application %SW146-147: those 2 system words contain the unique SD card serial number (32bits). If there is not an SD card or an unrecognized SD card, the 2 system words are set to 0. This information can be used to protect an application against duplication: the application is able to check the value of serial number and can go to halt (or other convenient action) if it is different from the initial one. Thus, this application cannot run on a different SD card. With Control Expert, the application must be read-protected. To do that, uncheck the Upload information in the Project settings. NOTE: to enforce the protection, you can encrypt the value of the serial number used in the comparison. NOTE: the complete SD card identification comprises several parameters including the product serial number (32bits). 82 35012676 10/2019 Installation of BMX P34 ···· Processors Precautions To keep the memory card in normal working order, the following precautions should be taken: Avoid removing the memory card from its slot when the processor is accessing it (green access LED on or flashing). Avoid touching the memory card connectors. Keep the memory card away from electrostatic and electromagnetic sources as well as heat, sunlight, water, and moisture. Avoid impacts to the memory card. Before sending a memory card by post, check the postal service's security policy. In some countries the postal service exposes mail to high levels of radiation, as a security measure. These high levels of radiation may erase the contents of the memory card and render it unusable. If a card is extracted without generating a rising edge of the bit %S65 and without checking that the CARDAC LED is off, there is a risk of loss of data (file, application). 35012676 10/2019 83 Installation of BMX P34 ···· Processors 84 35012676 10/2019 Modicon M340 BMX P34 ···· Processors Diagnostics 35012676 10/2019 BMX P34 xxxx Processors Diagnostics Chapter 8 BMX P34 xxxx Processors Diagnostics Subject of this Section This section deals with BMX P34 ···· processors' diagnostics.

The errors detected by the PLC concern: circuits which constitute the PLC and/or its modules: internal errors the process driven by the PLC or the process wiring: external errors functioning of the application executed by the PLC: internal or external errors Error Detection Error detection is performed at startup (autotest) or during operation (which is the case for most equipment errors), during exchanges with the modules, or during execution of a program instruction. Certain "serious" errors require the PLC to be restarted while others are left to the user to decide how to proceed depending on the level of application required. There are three types of error: non-blocking blocking processor or system 35012676 10/2019 91 BMX P34 ···· Processors Diagnostics Blocking Errors General Blocking errors, caused by the application program, do not cause system errors but prohibit execution of the program. When such an error occurs, the PLC stops immediately and goes into HALT mode (all tasks are stopped on the current instruction). The ERR LED flashes. Restarting of the Application After a Blocking Error To end this status it is necessary to init the PLC or to set the %S0 bit to 1. The application is then in an initial state: The data resumes its initial value. Tasks are stopped at end of cycle. The input image is refreshed. Outputs are controlled in fallback position. The RUN command then allows the application to be restarted. Blocking Error Diagnosis Indication of a blocking error is signaled by the ERR and RUN LEDs flashing on the processor front panel. The system words %SW126 and %SW127 indicate the address of the instruction which caused the blocking error. The nature of the error is indicated by the system word %SW125.

The nature of the error is indicated in the system word %SW125 (always updated). The following table shows the diagnosis of non-blocking errors linked to the execution of the program. System Bit %S15 at 1 %S18 at 1 %S20 at 1 Error Character string manipulation error Capacity overrun, error on a floating point or division by 0 Index overrun NOTE: There are two ways to change non-blocking errors linked to the execution of the program to blocking errors: Diagnostic program function, accessible through the Control Expert programming software Bit %S78 (HALTIFERROR) when it is set to 1. The processor's HALT status is determined via the flashing ERR and I/O LEDs. Testing and setting these system bits to 0 is the user's responsibility. 35012676 10/2019 95 BMX P34 ···· Processors Diagnostics Processor or System Errors General Processor or system errors are serious errors related either to the processor (equipment or software) or to the rack bus wiring. The system can no longer operate correctly when these errors occur. They cause the PLC to stop in ERROR status, which requires a cold restart. The next cold restart will be forced in STOP status to prevent the PLC from returning to error.

The BMX P34 20·0 processors have 150% of the BMX P34 1000 performance. What Is in This Chapter? This chapter contains the following topics: Topic Execution of Tasks MAST Task Cycle Time: Introduction MAST Task Cycle Time: Program Processing MAST Task Cycle Time: Internal Processing on Input and Output MAST Task Cycle Time Calculation FAST Task Cycle Time Event Response Time Page 98 102 103 104 107 108 109 35012676 10/2019 97 Processor Performance Execution of Tasks General BMX P34 ···· processors can execute single-task and multi-task applications. Unlike a single-task application, which only executes master tasks, a multi-task application .defines the task execution priorities. Master Task The master task represents the application program's main task. You can choose from the following MAST task execution modes: Cyclical (default setup): execution cycles are performed in sequence, one after the other. Periodical: a new cycle is started periodically, according to a user-defined time period (1 255 ms). If the execution time is longer than the period configured by the user, the bit %S19 is set to 1 and a new cycle is launched. The following illustration shows the cyclical execution of the MAST task: The following illustration shows the periodical execution of the MAST task: Both MAST task cycle modes are controlled by a watchdog. 98 35012676 10/2019 Processor Performance The watchdog is triggered if the MAST task execution time is longer than the maximum period defined in the configuration, and causes a software error. The application then goes into HALT status, and the bit %S11 is set to 1 (the user must reset it to 0). The watchdog value (%SW11) may be configured between 10 ms and 1,500 ms (default value: 250 ms). NOTE: Configuring the watchdog to a value that is less than the period is not allowed. In periodical operating mode, an additional check detects when a period has been exceeded. The PLC will not switch off if the period overrun remains less than the watchdog value. Bit %S19 signals a period overrun. It is set to 1 by the system when the cycle time becomes longer than the task period. Cyclical execution then replaces periodical execution. The MAST task can be checked with the following system bits and system words: System Object %SW0 %S30 %S11 %S19 %SW27 %SW28 %SW29 %SW30 %SW31 %SW32 Description MAST task period Activation of the master task Watchdog default Period exceeded Last cycle overhead time (in ms) Longest overhead time (in ms) Shortest overhead time (in ms) Last cycle execution time (in ms) Longest cycle execution time (in ms) Shortest cycle execution time (in ms) Fast Task The FAST task is for periodical processing and processing over short durations. FAST task execution is periodical and must be quick so that no lower priority tasks overrun. The FAST task period can be configured (1 - 255 ms). The FAST task execution principle is the same as for periodical execution of the master task. The FAST task can be checked with the following system bits and system words: System Object %SW1 %S31 %S11 %S19 %SW33 Description FAST task period Activation of the fast task Watchdog default Period exceeded Last cycle execution time (in ms) 35012676 10/2019 99 Processor Performance System Object %SW34 %SW35 Description Longest cycle execution time (in ms) Shortest cycle execution time (in ms) Event Tasks With event processing, the application program's reaction time can be reduced for events originating from: input/output modules (EVTi blocks), events timers (TIMERi blocks). Event processing execution is asynchronous. The occurrence of an event reroutes the application program towards the process associated with the input/output channel, or to the event timer that caused the event. Event tasks can be checked with the following system bits and system words: System Object %S38 %S39 %SW48 Description Activation of events processing Saturation of the event signal management stack.

The communication time spent per cycle varies considerably, based on the following elements: traffic generated by the processor: number of communication EFs active simultaneously traffic generated by other devices to the processor, or for which the processor ensures the routing function as master This time is only spent in the cycles where there is a new message to be managed. NOTE: These times may not all occur in the same cycle. Messages are sent in the same PLC cycle as instruction execution when communication traffic is low. However, responses are never received in the same cycle as instruction execution. 106 35012676 10/2019 Processor Performance MAST Task Cycle Time Calculation General The MAST task cycle time can be calculated before the implementation phase, if the desired PLC configuration is already known. The cycle time may also be determined during the implementation phase, using the system words %SW30 - %SW32. Calculation Method The following table shows how to calculate the MAST task cycle time. Step 1 2 3 Action Calculate the input and output internal processing time by adding the following times: MAST task system overhead time (see page 104) maximum communication system reception time and input management time for implicit inputs/outputs (see page 104) maximum communication system transmission time and output management time for implicit inputs/outputs (see page 104) Calculate the program processing time (see page 103) according to the number of instructions and the type (Boolean, digital) of program. Add together the program processing time, and the input and output internal processing time. 35012676 10/2019 107 Processor Performance FAST Task Cycle Time Definition The FAST task cycle time is the sum of the following: program processing time internal processing time on input and output Definition of Internal Processing Time on Input and Output The internal processing time on input and output is the sum of the following: FAST task system overhead time implicit input/output management time on input/output (see page 104) For the BMX P34 20x0x processors, the FAST task system overhead time is 130 s. 108 35012676 10/2019 Processor Performance Event Response Time General The response time is the time between an edge on an event input and the corresponding edge on an output positioned by the program in an event task.
