Good Morning,
I am considering during an upgrade attempting to use a 842E-M Ethernet IP encoder. I see I can configure it to read both position and velocity. For my application, I want to know total product ran and current line speed. The velocity seems pretty straight forward. If I have a 12" tracking wheel, and I set it to Rev/Min, then I essentially should have a direct Feet Per Minute (FPM) readout from the Encoder.I.Velocity tag (I hope). The counter part is what I am having trouble understanding how to configure from the manual. (Unfortunately I need to make sure this will work before I can buy one, so I can't bench test).
So say I set Resolution to 10,000 counts per revolution, and revolutions' at 1 (Maybe even could swap to 842E-S now that I think of it). My position should count up 10,000 times per 1 revolution, and that would tell me I've ran 1 foot. On my old SLC 5/04 with a 1746-HSCE2 card, I could roll over back to 0 after my count and just count up a counter every time. I can't find any sort of 'Roll over' or definitive information in the manual about this. It seems most application examples in the manual are expecting back and forth applications of some sort. Of course, I could just do a modulus command or something like that to keep track, but then what happens when the max position value is entered? The max value of the position counter register at 10,000 counts would hit overflow by 6100 feet ran.
I am clearly missing something, has anyone done a similar application before?
