GX Developer

5 posts in this topic

We uploaded a program from the PLC. This was on a rung ---| |---/-----{ } the ---| |--- Had an address & was true the ----{ } had an address but the ---/--- didn't. Whatever this is was preventing the Output from being true. No labels because we uploaded the program. We used the Demo version of GX Developer. Thanks George

All the -/- does is invert the output of the logic preceding it. It is well documented in the PLC programming manuals.

Why would one use this? It seems to me there are less confusing ways to accomplish the same thing.

Some programmers get used to that in other software where they have a normally closed output coil. I personally never do it.
