RS Logix 500 SCL instruction

how to write address in scl instruction and compare to scl instructions

Download manual 1747-rm001 from www.ab.com, look for math instructions (Chap 4), there you will find the answer.

Welcome to the forum.

If you are using a 5/03, 5/04, 5/05, or any Micrologix processor I strongly recommend you use the SCP instruction instead of the SCL instruction. You can find details on how to use the instructions in the manual mentioned in the previous post that you can get at http://www.rockwellautomation.com/literature/literature.html

One of our forum members wrote an excellent post on how to scale. He covers the SCL and SCP instructions in detail. I suggest you read it. http://www.plctalk.net/qanda/showthread.php?t=15069
