hi,

are you sure that you have a 2-wire-transcucer?

What is your "mA source"?

A 2-wire-module is powering the the transducer(see the manual page8). If your transducer is already powered you have a 4-wire transducer.  

hope this helps,

Hi,

what about diagnostic buffer of you plc - any entries?

If you go online in HW configuration, ist there any error code at your module?

hi Ganesh,

i had the same problem with a ET200SP (PN) it turned out one of the bases on the IO module was incorrect resulting in Zero Values on my AI. the module diagnostics on this ET reported the it as well. check the hware config online.
