Post by rafa on MODBUS TCP SERVER DONT AUTO-STARTUP ^{CODESYS Forge talk (Post)}
Dear all, I have a project where I have two ModbusTCP communication drivers in the application. It's working normally until a power outage or the installation panel is restarted. As soon as the PLC CPU is restarted, the Ethernet port is OK, but the TCP Server displays an "UNDEFINED" error. I can't reset the error using the diagnostic confirmation or the "mbserver.xConfirmError" bit. I noticed that the error only appears in the "mbserver.byModbusError" memory and the description is "UNDEFINED." The "mbserver.xError" memory doesn't flag an error. When using the warm restart function and then START CPU, the devices return to normal operation. The following demonstration images; The main question is: How can I make devices boot automatically?

Post by xnoop on MBTCP Slave configuration ^{CODESYS Forge talk (Post)}
Hello, I use Codesys 3.5 SP18 Patch 4 (64 bit) My Codesys project is composed of several dozen of Modbus TCP Slaves. I want to configure each of them by define : - Modbus TCP Slave Configuration : Name, IPAddress, port - Channels - Mapping I can't afford to configure manually and I need to find automatic way What possibilities does the Codesys offer? 1. I know it possible to use python script to create Modbus TCP Master and Slave. But I don't find anyway to create Channels and Mapping through the API 2. I 've tested to set mapping with file.csv on a Modbus Tcp Slave, but no way to import channels definition from file 3. I 've tried to use PLCOpenXml file. For example I 've create a project with an Ethernet device. I've exported it in PlcOpenXml file. After delete the Ethernet device, I've imported the PlcOpenXml file without success. I've tried the same by creating Modbus TCP Slave. Could you help me to find to good way ? Thanks

Post by nulltrace on How change Unity-ID in TCP Modbus Slave ^{CODESYS Forge talk (Post)}
Please explain how you configured that. Normaly, the Server should answer to all UID as long as gateway isn't activated. With activated gateway all UID will be forwarded to Serial-Interface, in taht case 255 has to be used for Gateway-Diagnostics. So that means, there is somethink wrong on your configuration. Which CDS-Version, Which Runtime-Version and so on are used.
