Post by hassaank on CODESYS V3+ WAGO PFC200+ MODBUS RTU ^{CODESYS Forge} ^talk ^(Post)
Hi everyone, I’m new to CODESYS and Wago devices, and I’m trying to set up Modbus RTU communication. I have a Wago PFC200 (8110) and a 750-653 RS485 module, and I want to read data from an energy meter using Modbus RTU. Thanks in advance for your help!

The Modbus Master example must work. We have used this several times on multiple projects. See https://forge.codesys.com/prj/codesys-example/modbus/home/Home/

Post by ekristoffe on Modbus UDP ^{CODESYS Forge} ^talk ^(Post)
UDP has no packet ordering mechanism, and Modbus protocol has no order checking mechanism nor session establishment. I'm sorry but this is false, Modbus IP based have the Transaction Identifier. Transaction Identifier - It is used for transaction pairing, the MODBUS server copies in the response the transaction identifier of the request. Modbus UDP make more sense than Modbus TCP in a local environment.
