  1. FIFO function

    Question about FIFO, I am using CP1L. What exactly I need is stack of four BCD values FIFO logic, the simplest possible working example of loading to stack and reading from it, because what I try with examples from manual (which is BTW useless for begginers) does not work.  just example: When I use SSET  I put: first stack address: D100 Number of words: &4 And it is not accepted for some reason?  
  2. Begginer problem CP1L - Calculation of time

    thank you Mendon, will try to finish it now
  3. Begginer problem CP1L - Calculation of time

    Thank you, Mendon, I know how to set constant value to counter, what I don't know is the right notation, to set the value using content from another mem location, for instance  content from mem address 100. For example like I have a timer TM and want to set value which is from location 100
  4. 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
