MODBUS module is incomplete (missing functions)


I’m posting this here because this seems to be the most active forum.

I’m trying to create a modbus master device to connect to a slave, using the Modbus TCP protocol.

Anyway, connecting through TCP goes just fine, nothing wrong with that. But sending a simple WriteReg command seems to be the problem.

When I do this, I get an error saying that 2 functions are missing, namely:

What gives? I mean… who would provide an incomplete product? I paid good money for this and it’s not working… did Zworld actually FORGET to write those functions?

Can someone help me?

Thanks in advance.
