Several of my HI 2151/20WC's will not retain the calibration or parameters if input power is removed. None of the units has a battery installed on the main board, although there is a provision on the board for mounting a battery. Why will some units retain the calibration and others not?
Do you have a complete map for M0 and M1 files inside HI 1746WS module? I am specifically looking for information about the meaning for bits and words.
I have a ControlLogix 5550 PLC and a HI 2151/20WC, HI 2151/30WC and a HI 2110WI Series Weight Controller connected to it via Remote I/O. I can get the weight back by moving a zero in the first and second word of the discrete output table. Now I need to zero out the unit before getting the weight. Can you tell me what bit to set in the second output word to zero the scale?
