Square D Sy/mate

MORNING,

I AM PERFORMING A PROGRAM TRANSLATION FROM A SQUARE D SY/MATE PROGRAM TO PLC5. I HAVE COME ACROSS AN IF INSTRUCTION THAT HAS AN N IN THE PLACE OF WHAT WOULD USUALLY BE A SYMBOL FOR COMPARISON i.e EQUAL TO, GRATER THAN AND SO FORTH. I HAVE NEVER SEEN THIS SYMBOL BEFORE, AND IT'S NOT IN THE INSTRUCTION SET IN MY USERS MANUAL. IN SHORT DOES ANYBODY KNOW WHAT THE N SYMBOL IS.

P.S- I'M TRANSLATING A PROGRAM THAT WAS WRITTEN WITH THE SY/MATE PLUS CLASS 8010 VERSION 2.06 DOS BASED PROGRAMMING SOFTWARE.

THANKS,
NICO

Possibly a negative transition contact? Also called an off-going one-shot.

Is there a 'Not Equal' function shown in the manual as an equals sign with a slash through it? Sometimes, in programs of that vintage, not all printers supported a character set that could depict all the instruction symbols, and you wound up with a printout that looked different from the examples in the manual.

Taking a step back, why are you translating to the PLC5 instead of to ControlLogix? If you're going to all that trouble, why not translate to something more current?

Steve is correct. The N in an IF statement means "not equal to".
