A few quick speedbumps in my project: Ethernet I/0

[Evilbeard]

I just got all the parts for my new project. I'm communicating to multiple drives using GS-EDRV-100s. I assembled my PLC, and connected it to the switch and the 3 EDRVs I'll be using. I set them up using NetEdit so they all had correct IP addresses. The PLC sees them and I add them in the Configuration Menu. The PLC tells me that they aren't the expected slave type. I don't have my GS3 drives hooked to them yet (they're 3 phase drives and I don't have 3 phase in my office (YET)). Is this the problem, or is there something I haven't configured properly? I could assemble this on a rolling portable jig and take it to the lab where I could wire it to 3 phase, but that just seems like a hassle.

Not sure what is reporting in the absence of actual data, maybe a GS1. As a workaround, you could try changing the config to GS1 and see if it gets happy.

attemped making them GS1 drives connected, no go. I still get the slave error. It looks like the attachment. It doesn't show the actual drives as the problem, but the GSEDRV100's.

Hook the drives to 120VAC on L1, L2 and ground.  IIRC the drives have to be present to prevent the EDRV100 from throwing an error.

There are really two errors happening. Prior to communicating with the drive, the EDRV100 has a default drive type value which is probably something like "unknown", so when the Ethernet I/O master attempts his validation it fails. I would considering this the proper behavior. The missing drive is really a second issue, in that if you had the drive present and then removed it, you get a different error. This too is the proper behavior.

One possible workaround is to mark the slave as optional. The error will persist, but the config will remain and the PLC stays in RUN mode.

Ok, I just wanted to make sure this was to be expected. I'm still writing the program (I have another couple hundred rungs of code to write yet), and I just wanted to get everything set up as I worked along. When I go to install this (we're gutting an old machine and refurbishing it with new controls and motors), it will be simple to line out this last bit. I just didn't want to get to installation and then find out I'd goofed something up majorly and then have to go back and rework a bunch of things. I'll let you know when (and I will) run into further little issues! Get back to enjoying your holiday! (I only have another 8 hours to go! YEAH!)

Definitely. EDRV's without drives are just E's.
