text: <s>[INST] Heartbeat for Powerflex 70 EC w/ ethernet with Logix Profile Hello, I came acrossed a slight issue today. I have a Powerflex 70EC VFD with ethernet connect to my CLX v16 PLC. The drive was running and I use the DriveStatus_Active bit as my running feedback. In the middle of the drive running, an electrician unplugged the ethernet cable from the drive which stopped the drive however the DriveStatus_Active bit stayed high and the drive displayed as running on my HMI. I was wondering if the Powerflex has heartbeat I can configure in the datalink so I can fault the drive on the HMI if I lose comms in the above scenario. [/INST] I would like to suggest a way to check the connection with your drive, that I've used in many plants...You may program a GSV instruction, checking the drive status using Module object... you may find some examples in the following technote: Aid 24162 In the RSLogix5000 online help, search for GSV/SSV objects - MODULE, to see what is available to check... see also attached screenshot with an example.... Hope this helps…- fuzzy logic \\n </s>
