Hello Hannibal, I am using real vars and it works, however, if I update those vars in real time it doesnt quite change it on y axis, do you think it is because it is not an integer?

Hello, I’m working on implementing Modbus RTU communication with a Carel controller (CPCO). I want to use the front RS485 interface through the DB9 connector. The issue is that I can’t get the communication working correctly. Below are the steps I’ve done so far: Connected pins 3 and 8 from the DB9 connector to the +/- RX/TX terminals on the Carel side. In the PLC shell, I set serialmode to RS485. In WBM under Administration > Serial Interface > Assign owner of serial interface, I set the port to unassigned. In the device tree, I created Modbus_COM with the following settings: COM port: 1 Baud rate: 19200 Parity: None Stop bits: 1 Created a Modbus client on this COM interface in RTU mode. Under the status tab, I can see it is in running state. On the client, I created a Modbus server and set the Modbus address of my unit to 1. Defined a few channels as FC03 to read holding registers according to the Carel register map. I checked the communication with the Carel controller using a USB-to-RS485 converter connected to my PC, and communication works correctly there. In the status tab, I can see that the Modbus server is polling, but there is no response from the controller. I also tried multiple times swapping A/B lines on the Carel side, but it did not help. Do you have any suggestions on what else I should check?

Hallo mattplc, man kann das Leid mitfühlen. OPC UA verspricht immer so viel. Aber wenn es um die praktische Umsetzung geht, und man damit die Aufgabe "schicke Daten von A nach B" lösen möchte, trifft man unvermutet auf den Endgegner. Der Mega-Bösewicht der Komplexität und Kompliziertheit. Was Dein Problem angeht, vermute ich mal das es mit dem Thema "Informationsmodell" zusammenhängt. Viel Erfolg auf Deiner Reise ✊✊✊
