Hello folks, I'm trying to create a Modbus TCP client directly from code, but I'm having some issues...

to do this I imported the library IoDrvModbusTCP, and both a ModbusRequest instance and a ModbusTCPSlave instance. I set the ModbusTCPSlave configuration using the UpdateCommunicationSettings method, but can't get it to connect. I followed the instructions at this link:
https://help.codesys.com/webapp/_mod_lib_modbustcpslave;product=core_modbus_configuration_editor;version=3.5.12.0
where it tells to use the property xEnable, which doesn't exist.

I attached an image that shows that when I create ModbusTCPSlave instance via code, it doesn't connect, but when I create a Slave in my device tree, it connects and works.

Unfortunately I can't update to SP17 and use the ModbusFB function block due to manufacturer constraints,

Does anyone of you know how to get my ModbusTCPSlave to connect?😕

Thanks

The ModbusFB library was written precisely because it is not possible to get your ModbusTCPSlave to connect - this only works when added to the device tree.
I would first try to open a project archive of your PLC in SP17 Patch 1 and get the ModbusFB library to work. So old runtime device description + compiler version 3.5.17.10 + IDE SP17 Patch 1. If it doesn't work, ask your PLC manufacturer to support you to use that library.
If that doesn't work, use a different PLC for your Modbus TCP Master purposes.
