The OPC server is available only with the OEM version or the full version, so the lite version of RSLinx does not have the OPC Server included. Rockwell Automation RSLinx 2.10 is an OPC server, meaning that any OPC Client should be able to exchange data with this server. This version has been upgraded to version 2.20. Rockwell Automation developed their own OPC Server in version 2.0 of RSLinx. Any OPC client, such as Lookout, BridgeVIEW, or other packages on the market, can connect to this server. With the release of Industrial Automation Server CD 1.1, this server became an OPC server. #Rslinx classic lite manual driver#The other one (Harmony.hrc) seems to be missing.The NI Industrial Automation Servers CD has an Allen Bradley (RSLinx) driver that can communicate with RSLinx through a dynamic link library (DLL). #Rslinx classic lite manual how to#I watched a YT video showing how to delete harmony files ( ) and then I noticed I only have one harmony file in my folder (Harmony.rsh). There are still no nodes showing in RSWho. #Rslinx classic lite manual install#I've spent the day uninstalling Rockwell software, then I deleted files from the registry editor containing Rockwell and then I did a fresh install of the RSLinx Classic Lite. I don't think any programs or apps have been added recently. Their IT staff has now made the user "administrator" as they didn't have all the rights on this PC before that. Sadly none dated back to before it stopped working. I'm not aware of any recent updates but I looked in System restore if there are any previous versions saved. #Rslinx classic lite manual drivers#I've already tried configuring different drivers and com ports before and I've tried again but it hasn't worked. Good luck with it – and remember, the more we know about your problem, the more detailed help we can provide. if so, you might want to try going "back a step" or two and see if the problem goes away. ĭoes your computer have a series of saved "System Restore" type files?. sometimes the registry gets messed up when that happens. Has anyone added any programs or applications to your computer lately?. sometimes these guys make well-intentioned changes to "protect" the computer system without realizing that they're making a mess of things that are important. ĭo you have an IT department involved with the maintenance and security of this computer?. sometimes this is scheduled to happen automatically during the dark of night – and you might not be aware that it has even happened. Has Microsoft "pushed out" any updates to your computer lately?. What operating system is running on your computer? (Windows 10, etc.). note that this approach is intended as something to grasp at in case your efforts with RSLinx don't work out. if that doesn't work, then here are some questions for you. If any of you have any experiences with similar problems I would greatly appreciate any advice.įirst I'd try the suggestion from geniusintraining. In the meantime the client has plugged in the computer containing the old SCADA which still works fine so the PLC's must be working fine. Then I came across something that said that deleting harmony files might help in situations like this. I tried installing a newer version of RSLinx but no luck. First I thought it might be the adapter cable so I replaced it but it didn't work. It worked fine for about 9 months then suddenly nodes couldn't be found anymore and the communication to the SCADA went dead. In RsLinx Classic Lite I configured the driver as "DH485 UIC devices", selected the correct COM port and RSWho found the available nodes. The PLC's used are Allen Bradley SLC 5/03. We used RSLinx Classic lite and 1747-UIC USB to DH485 adapter and then Kepware as an OPC server for Omron's SCADA. It was our first and so far only time working with Omron or Rockwell. Some time ago we replaced a client's old Rockwell SCADA with Omron's SCADA.
