If you write, from your HMI, these adresses, the CPU will overwrite it, with the"real" values. I suggest you usememory bits to send commands from HMI to PLC.

veljovic Posts: 6 Rating: (0)	Dear Wizard, I set buttons: 1. motor on -> M0.0 2. motor off -> M0.1 in PLC I write: Network1 LD M0.0 O Q0.0 AN M0.1 = Q0.0 when PLC start motor is off. when I set button 'motor on' , output is set and motor work. when I set 'motor off' output is null (motor stop) for 1sec, and again set (motor work). Where is the problem ?

You can also just use one bit. Motor on -> function Set bit M0.0 and Motor off -> Reset bit M0.0 Best regards, Wizard
