There are many kinds of DCS cards. The points to be explained below are the operator station in the xp313 of the central control DCS card of Zhejiang University. Let's have a look.
The operator station is an industrial PC, and its basic structure is not fundamentally different from the ordinary desktop computer. When a PC fails, it is necessary to use the plug-in method, the replacement method and the comparison method to determine which parts in the PC are faulty, and then replace the faulty parts or replace the slots (the replacement of PC parts should generally be guided by the engineering and technical personnel on the site).
In order to avoid blind replacement of components, the fault can be determined according to the number of alarm sounds when the PC is started.
When the display is abnormal and the industrial computer fault is eliminated, check the button setting of the display. Determine the position of the "D-sub / BNC" button on the front of the display: if the signal line on the back of the display is connected through the 15 pin D-type interface cable, the button is placed at the "D-sub" position; If the signal line on the back of the display is connected through the BNC type interface cable, the button is placed at the "BNC" position.
If the signal line on the back of the display is connected through the BNC interface cable, determine the position of the synchronization signal switch "sync. Switch": if the green synchronization signal (3bnc) mode is used, the switch is set at the "s.o.g." position; If the H and V separated synchronization signal (5bnc) or H + V mixed synchronization signal (4bnc) mode is used, the switch is set to "H / V" position.
When the color of the display is not pure, press the "demagnetization" button on the front of the display to eliminate electromagnetic interference. If the display button is set correctly and the display is still abnormal, the standby display or office display can be replaced temporarily, and then contact the supplier for display maintenance.
What are the precautions for the operator station in the DCS card xp313? The above explained the problem from two aspects. For more information, please visit our website http://www.sdjkyqyb.com Consult.
