How to configure PLCNext bus to avoid this Bus Configuration Error?

Vikash Chandola

I am trying to access AXL F RS UNI 1H serial card by following this example. I am getting failure in ConfigSerial method at following line

transferResult = acyclicCommunicationService-><span class="pl-c1">PdiWrite</span>(pdiParam, writeData);

transferResult.ErrorCode is set as F11 and transferResult.AddInfo is set 0. I checked into manual and it states that is a bus error.

Can you please tell how should i configure the bus?

Hi Vikash,

That should be covered by steps 1 and 2 of the procedure you linked to.

After you download the PLCnext Engineer project to the PLC, the D LED on the PLC should be solid green, indicating that the hardware configuration is correct.

Hi Martin,

Please correct me if I am wrong here, but I could not find any link to PLCNext project in the Part 01 and Part 02. I could see that there are acf.settings and acf.config file but no PLCNext Engineer project file or anything like that. Can you please point to step which step in Part 01 or 02 we get the PLCNext Engineer project?

Hi Vikash,

I am referring to Steps 1 and 2 in part 8 of the tutorial:

You have to create this PLCnext Engineer project yourself. It will simply be an empty project with the required Axioline I/O module(s) included.
