Hi,
Exactly this is all what I have in PBs....
PB1 to PB15, PB30.
FB0, FB1, FB238...........FB254....
So according to you, PB16 doesn't exist....
Now as this is a DOS based PC interface, What do think, where has the programmer stored the Calculations like Weighing scale monitoring for Actual load and Nominal load comparision, Keyboard function keys commands? I could not find this in given PBs, OPERATOR presses F1 and system shows Automode, Operator presses F6 and Fault is acknowledged, Operator presses F5, and next cycle is blocked.....
is this program stored in DOS? and not in PLC?
