Post by hwopereis on How to use Application Trigger in Modbus TCP Server ^{CODESYS Forge talk (Post)}
Hi, I'm currently reading and writing several registers with a Modbus TCP server as a subdevice of a Modbus TCP Client. If I read and write cyclically, there are no issues. The problem is this: I see there is also the option to write by "Application", which I would like to use. However, I don't know With the Modbus RTU client, I see there is a trigger variable, xTrigger, to trigger the writing tasks. However, I can't find any such trigger for the Modbus TCP Client. Does anybody know how to implement the trigger behavior for the Modbus TCP client? In particular, I struggle to find the exact "trigger" variable. I'm running Modbus Client version 4.4.0.0 Thanks in advance!

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.

Post by wbj0t on one variable signed to modbus tcp server device and modbus serial device ^{CODESYS Forge talk (Post)}
Hi. Raspberry pi 4 runtime. Runtime version 4.16, IDE version 3.5.21. Is it possible write new value for variable via modbus tcp or serial devices when both enabled? As I see - not. What can I do? It is terrible restriction.
