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?
