Hi, I've inherited an old machine that makes widgets.
it runs well at 300Widgets per min, but any higher it gets flakey.
This is a scan time issue.
The Scan time of the PLC is 20mS to 30mS. The sensors can be on for about 15mSec.
Is there a high speed area in the SLC 5/04 like OB35 in the Siemens S7 PLC's where I can put my counters to stop them getting missed?
any info gratefully received.
