How many of you maintenance Electricians that troubleshoot PLC problems or do programming, are using MOV functions ?
Just want to see how far I need to go with my PLC studies, just for electrical maintenance work.
all of it.... you may not be writing it, but if you are maintaining it, you need to know what it does, and how it works.
There are two parameters, Source and Destination (Dest) associated with the move command:
Source is the address of a word (such as I:1, S:3, N7:0, B3:3, or T4:0.ACC) of the data you want to move. The Source can also have a constant for a value.
Dest is the operator specified address of a word (such as I:1, S:3, N7:0, B3:3, or T4:0.ACC) where the Source data is to be moved.
in manufacturing, this allows a value for something to follow that something thru the manufacturing process.
let's say you have varying widths of a product, and want it to get transferred so that the product moves onto another conveyor centered on that conveyor.
you can use a photoeye to measure a value for the product, and send that value down the conveyor with the product, so when it gets to the right conveyor,
the kicker knows when to fire to move the thing onto the next conveyor centered.
then, you need to know how to edit it to get it to work, when conveyor tolerances come out a smidge off.....
if you don't know how this works, you may have a problem.
