DCS Troubleshoutting

To help troubleshooting some grafana helper dashboards have been created in the DCS grafana folder. 

The DCS Error Dashboard by default displays ALL the errors that area captured by DCS in a time range that can be tuned. There are a series of tabs that allow to select elements, zone, type of errors...

The same Dashboard contains statistical information to understand the recurrent errors and their source.

DCS Troubleshooting Dashboards

Magnet serial timeout 

When a serial timeout arise it means that there is a problem in the communication between the devil and the magnet device. The actions to perform in this case are:

1 - Assure the magnet is ON and is in "remote" (controllable by remote)

2 - Access the DCS Element dashboard by selecting the element that is in serial timeout the dashboard will return the devil number and many other information like the additional devices involved in the communication (like moxa and ports).

3- With the devil number access the Devil Manager and click the corresponding devil number to open a vnc session with the labview try to stop and start the devil. If the labview window is not present means the devil is crashed and you need to click reset button in the Devil Manager

If the procedure does not work and the serial timeout error is issued again in the  DCS Error Dashboard and the magnet cannot be controlled by the magterminal something HW is happening.

deep check

The DCS Element dashboard shows if there is some moxa involved in the connection if it's the case :

1. check the integrity of the cabling from the port of the moxa (found in DCS Element dashboard ) to the magnet interface
2. With the corresponding devil running check if the TX led of the port is blinking (the devil tries to access the hw).
   1. If not, must to check if the devil is running and Moxa serial lines documentation is aligned with the DCS Element dashboard.
   2. access to the Moxa web interface 
3. If the RX led of the corresponding port
