hi guys,
im kind of new to PLC programming, there's a project i need to complete and it's related to heating.
i did the PLC program in TIA V13 and the wiring for the TT.
The problem i'm facing is that the TT isn't sending any signal to my Analog input ( AI 8 x 13 bit )
The TT with transmitter is calibrated with no problems.
The wiring are based on manuals I've download from the internet. (two wire)
i've attach a picture of scale which is one of the block to read the signal of RTD and IW298 is suppose to be from the TT.

as you can see the signal from IW298 is "0".
Just wondering who can help me because I've been dealing with this problem for 2 days with no progress at all.
any help would be great.
and again, i new to this and did not have any proper PLC lesson. if would be great if you experts can help.
i will send my full program for the scale,con_c and unscale if requested.
