OK, first thing, I'm very new to PLC's and still learning. I'm confident enough to do forces, toggle bits, AFI's, and change setpoints when troubleshooting a problematic engine. Anything beyond that, I go hunt down a real Automation guy. This issue has even stumped them: My engines have 1771 PLC's but uses Bently Nevada 2201 vibration cards designed to fit in a 1771 chassis. The alarm and shutdown setpoints are in the 2201, sent to the AB PLC where it goes into a timer to trigger a bit. By fiddling around the 6200 program I was able to go into a section where I can read the BNC 2201 vibe card and change the vibe setpoints, but I can't do it on RsLogix. If I play long enough with 6200, I'll be able to reconstruct and write down what I did and pass a note to the Automation guy. My question is: will I be able to get into the 2201 Vibe card using RsLogix 5? It's been raining for almost 3 weeks down South, time to buy me a boat !!
