Expansion Module 8 digital inputs, 8 digital outputs User Manual Version 1.5 2 z 18 SDM-8I8O User Manual 1. Safety rules · Before first use, refer to this manual · Before first use, make sure that all cables are connected properly · Please ensure proper working conditions, according to the device specifications (eg: supply voltage, temperature, maximum power consumption) · Before making any modifications to wiring connections, turn off the power supply 2. Module Features 2.1. Purpose and description of the module The SDM-8I8O module is an innovative device that provides a simple and costeffective extension of the number of lines of input and output in popular PLCs. The module has 8 digital inputs with configurable timer/counter option and 8 digital outputs. In addition, terminals IN1 and IN2 and IN3 and IN4 can be used to connect two encoders. All inputs and outputs are isolated from the logic of using optocouplers. Each channel can be individually configured in one of several modes. This module is connected to the RS485 bus with twisted-pair wire. Communication is via MODBUS RTU or MODBUS ASCII. The use of 32-bit ARM core processor provides fast processing and quick communication. The baud rate is configurable from 2400 to 115200. The module is designed for mounting on a DIN rail in accordance with DIN EN 5002. The module is equipped with a set of LEDs used to indicate the status of inputs and outputs useful for diagnostic purposes and helping to find errors. Module configuration is done via USB by using a dedicated computer program. You can also change the parameters using the MODBUS protocol.

Communication configuration 3.1. Grounding and shielding In most cases, IO modules will be installed in an enclosure along with other devices which generate electromagnetic radiation. Examples of these devices are relays and contactors, transformers, motor controllers etc. This electromagnetic radiation can induce electrical noise into both power and signal lines, as well as direct radiation into the module causing negative effects on the system. Appropriate grounding, shielding and other protective steps should be taken at the installation stage to prevent these effects. These protective steps include control cabinet grounding, module grounding, cable shield grounding, protective elements for electromagnetic switching devices, correct wiring as well as consideration of cable types and their cross sections. 3.2. Network Termination Transmission line effects often present a problem on data communication networks. These problems include reflections and signal attenuation. To eliminate the presence of reflections from the end of the cable, the cable must be terminated at both ends with a resistor across the line equal to its characteristic impedance. Both ends must be terminated since the direction of propagation is bidirectional. In the case of an RS485 twisted pair cable this termination is typically 120 . 3.3. Setting Module Address in RS485 Modbus Network The following table shows how to set switch to determine the address of the module. The module address is set with the switches in the range of 0 to 127. Addresses From 128 to 255 can by set via RS485 or USB. Switch Adress SW1 +1 SW2 +2 SW3 +4 SW4 +8 SW5 +16 SW6 +32 SW7 +64 Ex. if switches 1, 3 and 5 are on than module addres is: Address = 1 + 4 + 16 = 21 Expansion Module 8 digital inputs, 8 digital outputs User Manual Version 1.5 6 z 18 SDM-8I8O User Manual 3.4. Types of Modbus Registers There are 4 types of variables available in the module. Type Beginning adress Variable Access Modbus Command 1 00001 Digital Outputs Bit Read & Write 1, 5, 15 2 10001 Digital Inputs Bit Read 2 3 30001 Input Registers Registered Read 3 4 40001 Output Registers Registered Read & Write 4, 6, 16 3.5. Communication settings The data stored in the modules memory are in 16-bit registers. Access to registers is via MODBUS RTU or MODBUS ASCII. 3.5.1. Default settings You can restore the default configuration by the switch SW8 (see 3.5.2 - Restore the default configuration) Boud rate 19200 Pariti Nie Data bits 8 Stop bits 1 Reply Delay [ms] 0 Modbus Type RTU 3.5.2. Restore the default configuration To restore the default configuration: · turn off the power · turn on the switch SW8 · turn on the power · when power and communication LED start blinking alternately than turn off the switch SW8 Caution! After restoring the default configuration all values stored in the registers will be cleared as well.

Watchdog function This 16-bit register specifies the time in milliseconds to watchdog reset. If module does not receive any valid message within that time, all Digital and Analog Outputs will be set to the default state. This feature is useful if there is an interruption in data transmission and for security reasons. Output states must be set to the appropriate state in order to assure the safety of persons or property. The default value is 0 milliseconds which means the watchdog function is disabled.
