Hi @Jeneburg ,
If you take a look in the page 104 of the "Modicon M251 - Logic Controller - Programming Guide" :
If I am not wrong based on the document the FC4 is not supported for Modbus TCP Server but if the client uses FC3 you can move the %IW to %MW in the controller.
I hope this helps you.
Hi @louispijpers ,
A workaround could be the use of the ADDM and READ_VAR function blocks, please find below the link to download the example:

If you do not know how to import it in your project you can take a look in the next video:
