  1. Hello Ausman, thanks for the nice words. I am still working on the program and, by the tests I've done so far, I almost there. Once I finish it I will follow your recommendations above and do the operation tests. I wonder if there is any available information about how to get to a good program, such as simple tips on making it a safe/reliable program?
  2. Hi Joe T., You are absolutely right. I just checked my ladder program and realizad that in every rung I used the SB 33 would work at the same way even if it is not there. That's why it was running as expected even not being the SB 33 functional for the my enhanced PLC. So I just removed it and it sti working right. I don't consider my program a complex one. Just some few contactors and valves that must work synchronized by a number of timers and an analogic transducer for pressure. As there are various ways of working, I had to develop a number of displays and subroutines. Sorry but I am afraid to say that this is my first PLC ladder program. We are a family company (machine manufacturer) and currently use a very simple, locally made PLC, but some overseas customers are asking for a global system that would be found more easily so that they feel more confident in case a spare one would be needed. Actually, my biggest problem was to understand the ladder reading flow, that now became very clear thanks to your and Flex727's help. Antonio
  3. I was betting a lot on this SB 33, for those codes I wanted to run just once on certain subs. Is there any valid SB for the same function? Is there a list of all operand that are valid for the Samba? The list in the PDF ladder manual are not clear for me. Thanks Antonio
  4. Thank you Joe T. and Flex727 for the tips. One more question, now about the SB33: If I have it in the Main Display subroutine, does it mean that it will not run at the CLP power up but will run upon its return from any other display when returning from subsequent subroutines? I will run your tips this Monday only as I don't have a CLP simulator, so I need to run it at the machine itself. Antonio
  5. Thank you Joe. And can I assume that, while in the loaded display, the Main routine will run all the way from top to bottom? Antonio
  6. Hello! This is my first post. Being a beginner in the subject, I am facing some troubles on doing a coding for a Samba PLC. I understood that the Main Routine always runs along with any other subroutine that was loaded by the "While Displayed" function in a loaded display. So, here coes my question: What if a subroutine is called from the Main Routine by the Call Subroutine (say Sub1) and, besides that, a new display is loaded and this displays contains a While Displayed subroutine (Sub2) that is not the same one that was called by the Call Subroutine? Would they run simultaneously? I mean, the three routines, Main, Sub1 and Sub2? Thanks for any help.
