PLC connect service can not work synchronous
Our costumer have system 800xA 5.1 revc DCS system and redundant ASCS servers.
Plc connect service has been locked on synchronising case. Because of that we shutdown secondary server and installed last good full backup on primary server. After than shutdown primary server, open secondary server and installled has been taken same date secondary servers full backup on secondary server. Finally open primary and secondary server again.
But now, When I create a plc connect service on primary server for primary server or secondary server, I can't see on secondary server. If I create a service on secondary server are happenning similar problem.
What can I make about problem.
Could you help me, please
You've posted several questions about PLC connect and TriangleWorks OPC servers. Is this the same system that you have been having trouble with for several weeks ?
You say the original problem was that one redundant PLC connect service was stuck "synchronising".
.... Did you sucessfully resolve the problems you were having a few weeks ago ?
.... Has this ever worked properly ?
I'm sorry, but I am confused by some of your questions ....
You restored an 800xA Backup TWICE ? Once on the primary and once on the backup Server. Is that correct ?
.... Thats not how 800xA backup/restore works. What EXACTLY did you recover from - eg an 800xA maintenance backup of just the xA system or a Windows image of all the software and operating system ?
If you restored from a backup - why do you need to create the services again?
.... The backup should restore everything including your service configuration.
You say that you create a service on ASCS1 but you cannot see the service configuration when you log in to ASCS2 ? Is that correct ?
.... Please post screen shots of exactly what you see.
.... What procedure are you following to create service groups for PLC connect.
Yes, this is the same system.
When I asked about PLC connect and TriangleWorks OPC servers to AKS, A asked to same question to regional ABB support center and Triange microworks OPC server company support center.
They sent a few configuration type. While I was trying thats occured "synchronising" problem. After than I deleted the systems on ASCS servers. And restore again from old full backup.
I used to primary ascs maintanance full backup files for restore to primary ASCS and I used to secondary ascs maintanance full backup files for restore to secondary ASCS.
Later When I Open computers again. PLC connect service for secondary server permanent change from service to synchronising. Becouse of that I erased service and create again.
So, the answer is "No, this system has never worked properly" ?
The 800xA maintenance backups save the whole system configuration. You should only restore the system onto the primary aspect server - ONE time.
What steps exactly are you doing to create the services ? Have you checked the "Post Installation" and "PLC Connect Configuration" manuals and followed the procedures for creating PLC Connect services ?
You should ....
1. Create a "Service Group"
2. Add "Services" to the group
3. Assign the Services to a computer.
Please post some screen shots that show your errors.
I istalled maintenance full backup first primars server after than I tryed plc connect service only primary server it was working.
After than open secondary server And then thats Can't synchronised
I try to remove server on nodes on configuratiion wizard. I saw this error message.
I erased oll service about plc connect servise and add again its can't work.
After than again. I installed to maintenance full backups seperate all serevers.
should I install to full backup primary server When secondary server open or shutdown?
You cannot restore an 800xA backup onto a running system, the whole system (all servers and clients) must be shut down.
If you did not shut down the system but tried to restore objects onto ASCS1 then the server will syncronize with ASCS2 as soon as it starts. Syncronising with ASCS2 overwrites the objects that you just tried to restore.
Please check the dates & times on some objects in the system. I suspect that you have not actually restored anything. This is probably a good thing.
Now you need to create the PLC_Connect service group again. Please refer to the installation guides on how to do this. System Post Installation (3BUA000156*)
Section 12, page 130.
Then you should be back to the same position as last month, where your PLC connect can work on one server or the other but not both at the same time. Then you can start troubleshooting again.
Go through the steps that we suggested the first time you posted. Identify what works and what doesn't. It is quite possible that your Triangle OPC server does not properly support "redundancy" in the way that ABB expects redundancy to work.
In the finally case PLC connect services are healthy working,When I started primary server first, primary server plc connect service was enable and
started Triange microworks opc server scada data gateway service.
By the way secondary server plc connect service gone to standby mode.
I shutdown primary server, secondary server service went to enable and started opc server service file on secondary server.
But Any data can't refresh and when I try to read and data, I saw to all data Bad/Comm Falure.
I started primary server pc again, while secondary server plc connect service enable, primary server plc connect service was working to standby mode and
OPC Server pogram was working on secondary server.
Data quaity went to good/Non-specific.
I don't understand anything about problem. Servise working true and OPC server working true. But System can't communicate to data, when primary server pc shutdown mode.
Could you help me.
