Currently Weintek’s built-in Codesys supports the following protocols:

Modbus TCP/IP (master)
EtherCAT (master)
CANopen (master)
Prerequisite: CANopen is only available on Weintek CMT-X HMIs that are equipped with a CANBus port.
EtherNet/IP (master)
PROFINET (master)

Note: Weintek’s Codesys cannot act as a Modbus TCP Slave by adding a single Modbus Slave device in the device tree, but users can utilize a specific Function Block of the ModbusTCPSlave library to achieve the objective.

Trying to add any Slave or Adapter Device without under a Master Device will not work.
