TOC Time is not a phrase I have ever seen used. Is it in MS, mS, or what? What PLC system are you looking at that uses it?

TOC I believe is "Theory Of Constraints'

This is a Six Sigma / Lean Manufacturing term for getting the job done.

When you use the phrase 'toc time' are you only interested in the time constraints?

If you described what your end goal is, or be a little more specific. I may be able to help a little more.

I believe it refers to the elapsed time between 2 operating points in a program execution. TOC is a Matlab command that means essentially the same thing. I have heard it used (albeit only by propeller-heads) as a quasi-benchmarking issue for relative speed of program execution.

mohdalharbi is that what you are looking for? If this is the case the importance would be dependant upon the application, sometime a PLC is too slow and a PC would be a better choice. But generally speaking a PLC will execute its program (RLL) in under 30MS (conservitive).
