Has anyone had the problem of the alarms on the HMI stop showing up on your mark 6?

We have a mark 6 for the BOP and one for the Steam turbine but only the turbine ones stop showing up

During the outage we disconect the switches to clean them and since then this happend

Thanks

 

Do you got alarms from "workstation alarms window" at least ?

 

Do you mean a Mark* VI?

Is the steam turbine HMI separate from the BOP HMI? Are there multiple GE Mark* VI HMIs and do they all fail to display steam turbine alarms?

Have you tried rebooting one of the HMIs that is not showing the steam turbine alarms? If so, what happened?

Do the HMIs run GE WorkstationST services? If so, have you tried stopping and re-starting the WorkstationST service? If so, what happened?

Is the Mark* VI turbine control panel a SIMPLEX or TMR control panel? If it’s a SIMPLEX have you tried re-booting the <R> processor? If so, what happened?

The alarm transmission is separate from CIMPLICITY, and sometimes it can get “confused.” If the HMIs use WorkstationST then the alarm display method is done using WorkstationST Alarm Display. Have you tried stopping and restarting the WorkstationST Alarm Display service. If so, what happened?

Without the answers to the above questions there’s little else we can say or suggest. A lot questions—but not very many if the HMIs don’t use WorkstationST….

 

Hi
Yes... Mark VI

We use the same HMI for the steam turbine and the bop. But only the BOP alarms are showing

We have reboot the workstations but that did not solve the problem

The steam turbine is a TMR service... We have not rebooted the controlers

I will try to start and stop the services on the hmi and give an update

Could it help if we cycle power on the controlers?

 

Do you got alarms from "workstation alarms window" at least ?

On the workstation and engineering station only alarms for BOP show. I can simulate alarm conditions on the steam turbine but they dont show up on the display on the cimplicity alam viewer.

Wierd thing is we have two steam turbines on separate tmr mark VI systems and the problem is on the two systems. Same thing, no alarms just in the steam turbine... The only thing they share is a pi historian.

 

Cycling the power of the controllers—one at a time, waiting a minimum of 30 seconds after turning the power off before turning it back on—might help. But it’s not recommended to do thus while the unit is running.

HOW MANY HMIs ARE THERE COMMUNICATING WITH THE STEAM TURBINE MARK* VI?

WHEN DID THIS PROBLEM START?
WHAT HAPPENED BEFORE THIS PROBLEM STARTED?

THERE SHOULD BE AT LEAST ONE NETWORK SWITCH NEAR THE MARK* VI AND IT SHOULD HAVE THREE ETHERNET CABLES CONNECTING THE SWITCH TO EACH OF THE THREE CONTROLLERS. HAS ANYONE DISTURBED OR CHANGED THE ETHERNET CABLES CONNECTED TO THE NETWORK SWITCH NEAR TGE MARK* VI?

If you’ve rebooted the HMIs then the WorkstationST Alarm service has been started during the reboot. There should be an icon in the System Trays of the HMIs for the WorkstationST Service. If you double-click on it you should be able to see the status of the related apps and services. Can you post a CLEAR photo of the WorkstationST services window?

Has someone changed the settings of the WorkstationST Alarm display to block the alarms from the steam turbine Mark* VI?

Again—when did this problem start and what happened or was happening before this problem started?

 

Hi
The problem started when we disconected the two switches you mention, on an outage, to clean them.

There are two hmi's and one engineering station

I check the settings on the alarm window of the operator and engineering HMI's. They are set to get alarms from the steam turbine and the bop

I will get some pictures soon and post them

Thanks

 

So, did someone take pictures of which Ethernet cables were plugged into which ports of the Ethernet switches? Usually they are managed switches--meaning there are groups of ports dedicated for different purposes. You say you are getting operation data, but not alarms. That usually means the connection to the Mark* VI controllers is working properly.

And, the number of HMIs just keeps growing....

Again, in the Windows System Tray at the bottom right corner of the monitor there should be an icon for WorkstationST services. If one of the services is not working (I'm suspecting that for some (strange) reason the WorkstationST Alarm Viewer service is not working properly) there is sometimes a small red X in the icon. Double-click on the icon and a small table should pop up in a short period of time that lists all the services which were enabled and should be running; if one of them is stopped it should indicate that.

There is a drawing which is usually provided with GE Mark* turbine control systems, called the Network Topology Diagram, and it usually shows which cables should be plugged into which ports for managed switches. Usually. Unfortunately, if any changes are made during or after commissioning usually the drawing doesn't get update and if the person who made the changes doesn't mark up the site's copy then that information is usually lost. That's why it's a VERY GOOD idea to take pictures of the switches and cables in the switch ports to refer to when they are unplugged and plugged back in--so that they get returned to the proper ports. If the cables DON'T have labels appropriate labels should be ADDED to the cables BEFORE unplugging them, so they can be put back where they came from with more ease.

But, in my experience if operating data is coming through from the Mark* VIs via the network switches then alarms should also be coming through. But, it's possible for some strange reason if the cables weren't plugged back into the ports from which they were taken that this MIGHT be the problem. It would be odd, in my opinion, to get operating data but not alarms but stranger things have happened. Alarms are "broadcast" whereas operating data is more targeted (or at least it has been in the past). And, as usual, GE has the only secret decoder ring when things go awry (meaning they haven't written good manuals and documentation for troubleshooting problems like this--in the past, anyway). Yet anothe reason that taking pictures and making sure cables are labeled is so important before unplugging them.

But, at least you know when the problem started. So if you have to get the supplier involved (who will likely have to get GE involved) they can hopefully get an answer quickly.

 

After checking everything we did a reset on each one of the controlers and we finaly got alarms on the steam turbine

Thanks for the support specialy to the great WTF

Have a great weekend everybody
