Tim, "All of the #2s should not be connected or set to the opposite condition." Could you elaborate on this statement? What do you mean by #2's? Oops, I meant 1s; DEVLM1, IGNLM1, AVLLM1. The GDEV is also used for Valves where you may have 2 limit switches (DEVLM1 & 2) as open/closed feedback. As long as there is no other device between the GDEV and the MCC that could bypass the GDEV command, nothing else should be required to get what you want. Joseph M.

"All of the #2s should not be connected or set to the opposite condition." Could you elaborate on this statement? What do you mean by #2's? The device between the GDEV and the MCC is an Eaton C441 Monitoring Relay. Basically, you connect it to a switch that is also connected to the FDSI FBM, and it can monitor the device statuses and turn things on and off. It's pretty simple with no logic solver in it.

Riccardi Sent: Friday, May 18, 2012 8:12 AM To: foxboro@xxxxxxxxxxxxx Subject: Re: [foxboro] GDEV configuration Tim, You have lots of options but the basic connection for the motor Run feedback is DEVLM2. DEVLM2 Device Limit Switch 2 is a boolean input for reading the Opened/Running limit switch. When DEVLM2 is true, the device is Opened/Running. Make sure it is not ignored; IGNLM2 = 0. And it is configured as available; AVLLM2 = 1. All of the #2s should not be connected or set to the opposite condition. The big question is, do you have anything between the GDEV and the MCC; i.e., a PLC, HOA, etc. Joseph M.

We are upgrading our Motor Control Centers, and we have some fancy new MCC buckets that can talk over Ethernet to an FDSI block. Someone decided it would be a good idea to allow the board operator to turn the pumps and exchanger fin fan motors on and off from the DCS, as well as being able to operate them locally as they always had done in the past. Previously, if we needed a pump or fin fan motor started, the only option was to send an operator out to do it. In most cases, we didn't even have feedback status for the pump or fin fan motor, but now we do. Since this project was run by an Electrical Engineer who can barely spell I/A, he didn't put much consideration into the graphics or DCS configuration until very late in the game, and he ended up farming the job out to Invensys at the last minute. The Invensys engineer he hired was already on site helping us with a cutover, and he had to throw something together in his "spare" time. He did a very thorough and complete job with the information he was given and with the time constraints he had, but unfortunately, he had to leave and go to another job, and now what we have isn't quite right. The Invensys Engineer used GDEV blocks on the graphic to start and stop the field devices. What we are seeing is that the feedback from the status bits is not configured correctly. The GDEV currently does not know what the status of the device is. If you call up the Detail Display of one of the GDEV blocks, it is in whatever position it was left at by the graphic, even if someone has started or stopped the device locally with a field switch. My question is, how do you properly configure a GDEV for ON/OFF status feedback? There are all these options, and the block book is not particularly helpful in deciphering which to use or not use. We basically want the GDEV block to know what the status of its device is, so that when we click on the device, it knows whether to prompt us to start it if it is off, or to stop it if it is on. Right now, the GDEV is assuming that whatever the last command we sent to it is the status of the device, which isn't necessarily true. The device status comes back to the DCS via the first bit of an FDSI PAKIN block, but I haven't had any luck figuring out which parameter on the GDEV to connect it to. There is only a RUNNING bit, and no OFF bit; that is, you can only tell the device is OFF if the RUNNING bit is zero. If I could get Invensys to work on this, I would, but it's not easy traveling to Alaska, and I think this should be an easy fix.
