Description of router app Router App Protocol MODBUS-RTUMAP is not contained in the standard router firmware. Uploading of this router app is described in the Configuration manual (see [1, 2]). The router app is not v4 platform compatible. Using this module, it is possible to periodically read data from the buffer which stores values obtained from connected measuring devices (meters). To each measuring device can be assigned a certain number of registers (or coils). These ranges follow each other, so RTUMAP module reads data from a total number of assigned registers (or coils) starting from the specified start address. Well-arranged model diagram can be found in the following figure: Figure 1: Model diagram For configuration RTUMAP router app is available web interface, which is invoked by pressing the module name on the Router apps page of the router web interface. The left part of the web interface (ie. menu) contains only the Return item, which switches this web interface to the interface of the router. Protocol MODBUS-RTUMAP Manual 2 3. Configuration of router app The actual configuration of this router app is performed via the form on the right side. The first item in this form Enable RTUMAP on expansion port is used to activate these router app. Meaning of other items is described in the table below: Polozka Expansion port Baudrate Data Bits Parity Stop Bits Split Timeout Read Period TCP Port Start Address Význam Corresponding expansion port (PORT1 or PORT2) Modulation rate (number of distinct symbol changes signaling events made to the transmission medium per second) Number of data bits (7 or 8) Parity (none, even or odd) Number of stop bits (1 or 2) The delay between readings (in miliseconds) Period of reading data from the buffer (in seconds) TCP port number Start address of register Table 1: Description of items in configuration form At the bottom of the configuration form is also available a list of connected meters with information about their settings. All changes will take effect after pressing the Apply button. Figure 2: Configuration form Protocol MODBUS-RTUMAP Manual 3 3.1 Adding and removing a measuring device 3.1 Adding and removing a measuring device Individual meters (measuring devices) can be removed from the list by clicking [Delete] item which is situated in front of the meter description. To add meter click on the [Add Meter] item. Before adding a meter, it is neccessary to enter Meter Address, Start Address, number of registers or coils (Number Of Values (Register or Coils)) and select Read Function (see the figure below). This way it is possible to add up to 10 devices. Figure 3: Adding a measuring device 3.2 Read and write functions The following figure describes functions that are used for reading and writing between PC, RTUMAP router app and meter. Functions 0x01 (read) and 0x0F (write) are intended only for coils. To be able to write some values to coils on MODBUS RTU device (by function 0x0F), set the read function in a meter declaration to function number 1.
