Hello I am beginner and would appreciate some help for the part of the assignment.
3 contacts, 1 coil
I am trying to make a diagram in CX Programmer, using CP1L PLC, have some experience in usual programming but not much in Ladder diagrams,
Exit (Coil) should be ON for a certain number of seconds ((T*2sec)+(P*1sec)) where T multiplier, could be 1,2,3 depends which input of those 3 is currently on, and P multiplier is value of the previous usage of contact (1,2,3 or 0 for the first use).
Contacts does not have to be diff up, I know that part, I am actually having problem in using variables instead of direct values to calculate the number of seconds for the ON state of coil.
Thank's in advance,
Deni
