I want to communicate with a third party component via Modbus TCP. Unfortunately, I have very little experience with Modbus TCP. Is there anyone who has a working example project or similar that they would like to share with me?
Thanks in advance!
Hello, if you want to read and write with a ctrlX to a Modbus TCP device ("slave") you have several posibilities:
Is there more information available about using the:
There is PLC library name CXA_ModbusTCP in ctrlX PLC engineering.
In this library, you may using FB of IL_ModBusTCPClient as a client of modbus TCP. You can find a simple code example.
There is another possibility with the Modbus TCP App, where the Modbus Register will be available in the Data Layer realtime.
I need to set up the ctrlX core as a modbus slave and connect it to a master (robotcontroller in my case). Can this be done with this app?
Is the app already available?
Thanks in advance.
@RobotART_Walter The app is at the moment in prototype phase. Please get in contact with your known sales person for getting access to it.
For the actual functionality please have a look to the store page in our community. At the moment you can set up a ModbusTCP Client that can communicate via every standard ethernet port of the ctrlX CORE to a connected master.
Like mentioned above every standard Ethernet port can be used. You simply have to set up the network settings correctly. The only not usable port is XF50 as is reserved for EtherCat only.
