I got those screenshots in the wrong place, but ya'll get the idea ......Later Todd
when in "timed mode" my PID funtion is "looked at" every "Loop update" time by the program.
when in “timed mode” my PID function is “looked at” every scan ... but it is only “executed” by the processor every “Loop Update” time ...
STI mode is "looked at" every scan of the program.
STI mode is “executed” by the processor on each and every scan ...
I need my PID action to “freeze” when a motor stops turning, and pick up where it left off when the motor starts again. Can I do this by enabling the manual bit?
And do I need to MOV the PV to the SP while in manual?
I thought I'd try this again, in case someone hadn't seen it. I would appreciate any and all opinions or suggestions.Hi folks... Before I get too far along in my project, Could I get your opinion on my method of trimming my analog output to the slave drive. If you go back and look at my code you'll see that I plan on manipulating the offset to trim the output. At 1st I was trying to manipulate the rate, but thats when I ran into the issue of math over run faults. Is this an acceptable method?
Thanks and Later....Todd
