Stuck while implementing Modbus Explicit Messaging using GPL

[Kik]

Hello Team,

I'm still working with my M340 PLC and now trying to implement modbus explicit messaging with GPL. I'm using this video https://www.youtube.com/watch?v=ILjCjr1Oa9k

At 16:39, this expert is showing us the variables we should get in "public". For me, "public" is empty.

I followed this video step by step.

The only difference that I have is the Networks. The expert added a new Network (called EthernetCPU). I didn't because I'm using a NOC 0401.2 and I can't link any network to it.

Does it make sens ? Is it the problem ? What do you think about this situation ?

In advance, thanks for your help
