Basic Indicators
Basic Indicators •
Processor (everything should be green) –
Run – solid green to be in RUN mode •
–
I/O – solid green means good modules • •
– –
– –
Otherwise put in RUN mode using key switch Otherwise look for absence of green OK LED on module Note that some modules do not have OK LED
Force – off, we do not use forces! RS232 – solid or flashing green, communicating with touch panel BAT – should be green, but generally is not critical OK – must be solid green! Any red means we need to go online to see what the problem is. A power cycle will probably fix it, but we will lose any information on what caused the fault.
Basic Indicators •
Power Supply –
•
OK – green
Network Module –
Link – green, good link to switch
–
Net – flashing green, Ethernet traffic
–
OK – green, module is good
–
Module on the ControlLogix
–
Card on the FlexLogix
–
Built in on the CompactLogix
