How to configure Modbus TCP in machine expert Basic with TM200CE32R
Hello, I have a modicon TM200CE32R and I am trying to test modbus tcp with other devices. I am trying to use the modicon as a slave and another device as a master however when I follow the instructions to configure the modbus connection there is an option that is missing which I have highlighted in the image. I am following the instructions as laid out on pg 116 of the Modicon M100/M200 Logic Controller Programming Guide.

If you allow Modbus Server in Machine Expert Basic (Configuration-ETH1-Modbus server enabled) then complete M200 data memory (%MW and %M) is available to any Modbus Client/Master at Modbus/Unit ID 255. You don't need to setup anything else. Your point to Modbus mapping is to add additional Modbus mapping at Unit ID 248 or other number with separated memory. But this feature is not available for M200 at the latest version of Machine Expert Basic 1.4.
