Hello everyone a quick question that should have been asked already.
I have a 1734-IK counting card that can hold an entire length within itself. Great no resetting of count (rollover issues)so this is ideal 900 pulse = X # of inches / 12 gives me number of feet. Perfect.
So the internal count = 34789667 and we loose power on the machine. guess what.. my count is now zero (0) how do I retain the previous length count so that on a power up (FS, first scan) my program starts where I left off.
There are several hardware methods (none are really practical) including a Battery backup or UPS. I would prefer to do this in programming. Also I can be off by a couple of 1000 pulses.
We are using an L16 controllogix processor
Thank you in advance
