I want to monitor the cycle times of some of our stations (the process, not the CPU cycle time). We had a case recently where throughput was down and nobody new why and we discovered that a station which normally completes its work cycle in about 35 secs had drifted up to about 42 secs over the last three months.
I intend to save the cycle times in a 256 Byte array in a DB and compare the average with a Target time and issue a warning on the OP if this time is exceeded.
Does anybody know if there is a Siemens FC or SFC which will do this for me, I can't find any likely candidates in the Standard Library.
I know can do this in a loop, but I'm a bit nervous about cycle time contraints if I do it all in one fell swoop and I don't like loops that only perform one step per cycle, because I find people sometimes have problem figuring out what's going on with them.
If anybody's got a boxed function which does something similar, I be interested to see it.
Cheers
Roy
