Not Responding to Process Request

[OneHoppyGuy]

I'm programming a BCS 462. Everything has been working fine until...
Selecting process 2 will change the process to process 2 but process 2 will not enable. As in, no light or response from Web Input buttons. Force state jump does nothing.

I'm sorry your're having trouble!

When you say you are "selecting process 2", do you mean choosing it from the "Select Process" box;

or are you referring to clicking it within the left-hand column on the screen;

When you choose a process from the select box, the display will show you details about the process, but only clicking it in the left hand column (second image above) will actually turn it on and off. Also, when you click a process in the left hand column to turn it ON, the display will automatically switch to showing you details about that process.

Hope this helps!

Nope, it doesn't...
I'm selecting the button from the left column.
It is as if the process is being killed as soon as it is spawned

BTW This isn't my first BCS rodeo.

I tried resetting the BCS and reloading the config files. Same result. The config settings for process 2 have an error so I need to redo that process... oh well

Nope, that didn't do it either... process 2 still won't respond. Turns out the error is in the sys.cfg file...

A few things to check;

• see if you have anything configured in ladder logic related to that process
• see if you have a condition in state 0 of that process that could be leading to a process off end point

It sounds like your assessment is correct; something is turning the process right back off as soon as it comes on.

error in the ladder logic...

Glad it's all straightened out!
