I do not do Rockwell any more(that's another story) , but it was just a suggestion, I know that some IDE's have problems even text based search rather than symbol/tag can give unreliable results. The other possibility is it does not exist elsewhere but retained as true.
I cannot find what controls this bit in logic.
Some kind of master bit.
search only shows this bit
Control Logix 5571 CPU
Any ideas??
That bit is aliased to an input, there will be no coil, it's the input that controls it. Look for whatever device in the tree is named B1_MSTR, slot 2 input 1. Point I/O maybe?
THIS PROGRAM YOU HAVE SHOWN A SNIPPET OF IS SO OBVIOUSLY A CONVERSION
I am going to post this in CAPS, feel so strongly about it..
THIS PROGRAM YOU HAVE SHOWN A SNIPPET OF IS SO OBVIOUSLY A CONVERSION, THE TAG NAMES ARE COMPLETELY MEANINGLESS.
If you are now "in charge" of this program, make it your task to put some meaningful tag-names in place of the converted addresses.
Take your time, work out what each "address" does, what it means, and change its name to something that means something, that you, your colleagues, and all yours and their successors will thank you for.
Even if it takes you a month, a year, or whatever, it is worth doing.
