Compact Logix Module Config Changes

[Stupidav 1]

I have a 1769-HSC rev A on a Compact Logix system. I can't seam to remember and my searching has come up short. I need to change the Mode of the Ch0 input, will this require the controller or module to restart? Currently we can't take this system offline or even restart it at this point in time and I don't want to mess up and since I can't remember, any help is appreciated!!!

In the ladder you must: 1. Disable counting 2. Place the new config information in place 3. Issue a 'Reconfig' message to the card 4. Wait for the 'message done' bit and check that the config valid bit is ok (actually I had to delay a couple of tenths of seconds looking for it as it was still on from the previous reconfig) 5. Re-enable counting. If you need I'll look for a copy of the specific code we used. We were changing the rollover point of a ring counter.

Thanks after reading your post the module does restart but fortunatly the Compact Logix doesn't worry about that too much so everything kept going.
