Seversean

Actually I'm still getting disconnected from Kepware here and there. Is there a bit or a way to detect this disconnection?

Not sure, but I suspect that maybe it did this by default.

I emailed this same question about bit SB350 to support and never got a response.

Got it, I realized my problem. This whole time the help file tabs sidebar had been slid over as to make it hidden. I couldn't see search or index or contents or anything. Been driving me mad trying to find anything.

Can you tell me how to find the alarm help file? I came across it once and now I can't seem to find it.

Are you familiar with how to use this bit? Left on all the time?

Not getting responses from the forum on this or even Unitronics. Seems odd.

Looks like maybe this fixed the disconnections.

Having this same problem and found bit SB350. Turned that to a 1 manually and my alarm screen came up. No idea if this is the way it's done. I've never found any mention of this bit anywhere.

OK, I've looked at that as well as finally found the help for the Alarms, which I printed, because I doubt I could find it again. After configuring alarms and adding PLC code as shown in examples and help I still never get the alarm screen up. Then I came across bit SB350 'Show Alarms on LCD (On=Show, Off=Hide) Turning this on popped up the alarm screen. So now I'm confused how this bit should be used. Left on all the time? Turned on in ladder logic? There has never been any mention of this bit anywhere.

I've had issues with this still off and on. Sometimes one Kepware server loses connection, or both. Sometimes I lose PC connection all together. For the time being I've put a comms reset button on the HMI to reinitialize the ports. Even this was a pain because I'd find I'd reinitialize and only one Kepware server would connect. I then found having a delay between the two different Modbus connections initializing fixed that and they will both return to connectivity. I'm not sure why I lose connection, perhaps it was SI101? It was set to 2 and I changed it to 10. Even when Kepware wasn't communicating the bits showed there was a connection so not sure how to detect no connection automatically and reinitialize with that.

I'm trying to get more information on getting the alarms screen to work. Is there a good training video or document for this? I'm using a V570.

One issue I've come across is losing communication randomly. Usually both IO servers will stop communicating Modbus, reinitializing the connection fixes it. But yesterday I lost both Modbus and PC connection and couldn't even connect to the PLC at all to troubleshoot. In the mean time I've put an initialize comms button on the touch screen and have the comms reinitializing automatically each day at 6am. When I've lost comms the SB bits all show connections still. Not sure if anyone has any idea or fixes for this?

I got it! Turns out the last issue was the fact I missed a port setting in Kepware on IO server 2 and it was still set to 502 instead of 503. There's port settings in Kepware under both the channel and the device so just missed one of them. Pulling data on both IO servers now, I'll keep an eye on it to see it continues to work. Joe, wish I could take credit (or maybe not with some of the bugs) on putting together this entire program but I didn't. I just inherited these machines running and was tasked with installing LAN adapters on all of them and getting remote connectivity capability as well as data monitoring. Sounds like the V700 would have been the way to go but that was the machine builders decision for whatever reason. Thanks for all the help. I'm sure I'll have other questions eventually.

I thought maybe this screen would be helpful. Sockets 0-3 initialized. Sockets 1,2 utilized. 1 being my PC and 2 being IO Server 1. No other connects.

In the past I had one other device, a wireless sensor gateway, that would only accept one connection. My work around was messaging the data to an AB Micrologix and reading it out from there. That was only one device, since this is 12 devices I'd like to figure out how to get dual connections working in this case. I've attached the project file. 2-4-2021.vlp

Yes it is definitely a licensed version of Kepware, we have many other devices connected for a couple years. Allen Bradley, Koyo, and now trying Unitronics. Current situation is I am back to IO server 1 collecting data while IO server 2 is unable. Screenshot below is IO server 2, not getting any data at all. IO server 1 showed good reads. Strangely, at one point IO server 2 was getting data while IO server 1 wasn't. They seem to be fighting over the same port still even though I've pointed the to two different network ID's and ports.

Yes, those were the ones, Modicon 984. I did actually have one of the sockets mistakenly set to Master so that has been corrected. I'll have to power cycle and see if there's any change. We have 12 high pressure coolant pumps and filtration systems here running with V570's. The objective is to get them on Wondeware for higher visibility on their status and alarms. I'll get back to you after reboot and if still having issues upload the program. Does anyone have any experience from the Kepware side of it?

After all that neither IO server can poll the PLC now. Before all this I was able to at least get one of them to poll the PLC successfully. It shows I have sockets 2 and 3 initialized but no connections.

I believe this is what you meant to do...

Yes, used ladder logic in AB of course but I think things are defined differently. Looks like what you're calling a rung is the whole blank space between the lines with the number 1,2,3 etc. And what I'd call a rung you're referring to as a logic thread. AB constructs the rung lines automatically as you drop in instructions. I believe this format is similar to Modicon and others I've used on occasion. Calling the whole space or rung a 'Net'. Just different and I have to orient myself and figure it out. So I need to create a new 'Net' and put each individual rung or logic thread per Net. I think I can see why it didn't work now... Exactly what I meant by new at Unitronics.

Not sure why but this doesn't appear to have worked. SB149 and SB150 are not set to 1.

OK, I can redo all that. Simplify it. Again, I have zero experience with Unitronics so using the software, moving stuff around and creating new rungs is all foreign to me, coming from Allen Bradley background. BTW the config in the Kepware does ask for the network ID number...

OK, these are the new rungs. So the default for socket 3 is TCP(20257) but I've initialized it to TCP 503. It still shows up in the config as TCP(20257) though. Guess that's just documentation saying thats the default? See any issues with this? Forgive any mistakes, I have no experience with Unitronics.

Curious how mine is working then if you need to initialize and configure each socket. I initialize socket 0 (502) and then configure Socket 2 (502). Seems like maybe socket 2 is working without any initialization?
