PANEL VIEW 1000 :communication Driver fault

[sotos37]

The problems has started a couple weeks ago :
Randomly 2-3 times per shift an error appeared
communication driver fault 645
after pressing the touch screen another error appeared
communication driver fault 637
After restarting the device , the machine worked normally

But now after booting an alarm appears
MINOR FAULT 1007
COMMUNICATION FAULT 649 0,0

• The panel view is connected via CONTROLNET with a controlLogix (1756-PA72/B)
• The CPU (LOGIX5555) is on Run mode
• The controlNET card has two leds :
On: is flashing green
Channel A : is flashing red

On the controlNet display there is a message:
NET ERROR
%C07
Kp0V
nC00
nV00
A#01

• The panel view on the back on the right side has two leds
Both of them are off after booting

thanks

Check the condition of the cable, connectors, a terminators.

and no one changes the net configuration? can send data to the panel have a different length? and what about RSNetWorx for ControlNet?

[sotos37]

no changes have been made to the net configuration
Also the cables and the terminal seems to be ok.
is it possible that the controlnet card is been defective?

[Kirillij]

yes. its can be. use "RSNetWorx for ControlNet" for check net config and condition of the net-card.
repack connector cable is also good (if the system is not new).
