Hello everybody! I am working on upgrading an exisiting PLC system comprising of a Symax Model 300 PLC. I am replacing it with an Allen-Bradley ControlLogix. I have a print out of the old program (thanks to OZEE) and there are a few instructions in it that I cannot understand completely. For example there is a timer which has some input logic conditions to start the timing (like all other timers) but it also has the line connected directly to its 'clear' input. There is another timer that has similar connections where the only difference is that it has some logic to trigger the 'clear' bit. I have no clue about how these timers are operating.
It would immensely help to have an instruction set reference for the Symax PLC. If anyone has anything please share it with me. I would not mind paying shipping charges for a hardcopy.
Thanks fellas,
I appreciate any help I can get.
