So machine basic

Hello,

So I'm currently trying to read an analog sensor of one of the expansion modules. The problem is that it's not reading it at all. When i try to read the sensor using the plc (cos it has analog inputs) there's no problem at all. so, the reason that i'm reading the sensor with the expansion module it's because I want to read the information in 4...20 format. which cannot be done by the PLC.

the hardware is the following:

Schneider
TM221CE40R
TM3AI4 X2 (is there a problem if a connect two analog modules at the same time?)
TC type J and K109TC
