troubleshooting with AI Module
so here is the machine which works s7-300 CPU it has DI/DO's and with soame AI's , previously it has AI 6es7-332-7KF02-0AB0 (12bit) module in which some of the channels were not working, now we planned it change it with 332-1KF02-0AB0 (13 bit) which has to read analog out put (4-20mA) from 2 wire ultrasonic transducer (SITRANS PROBE LU). but as far after placing the new module the input isn't reflecting on PIW 272 i have configured this new module in simatic manager with same address from the previous one. I shows the reading software -32768 which sometimes also termed as open sensor. but i made changes to the wiring according to the new one.
so is there any problem with the new module because previous one was (12 bit) now the current one is (13 bit).
or is there any other way of configuration for 13 bits input module.
