Thanks for your advice. I am attaching you the connection drawings in pdf format.Here i am using 314C-2DP CPU which is having inbuild AI and DI. I am connecting at the proper channel for mA measurement. I have checked with current simulator, it is working fine. Moreover i have given the 24VDC supply to transmitter from the PLC Power supply.

Hello PLC Engineer; Your connection diagram misses important information, especially in the case of analog modules. We needed to know to what terminals you were connected, and how the different terminals were connected together on the front connector. Where is the power to the PLC analog modules connected to? Are you using the Mana connection to ground all othercommon pins fron other channels? Channels are generally not isolated one from another in the compact CPUs; you have to ensure they are, by adequate wiring. Here is a list of FAQs that Siemens support prepared for the wiring of analog IOs. Since you are using a 4-wire transmitter (the Sitrans P has its own source of power, it is an active transmitter) skip the 2-wire explanations. But be sure to read the "What to do with unused channels"entries. http://support.automation.siemens.com/WW/view/en/22723668 Hope this helps, Daniel Chartier |
