Module Status (MS)
Table 46
explains the states of the Module Status (MS) LED of the E300 EtherNet/IP
Communication Module.
Table 46 - EtherNet/IP Communication Module Status Troubleshooting
Possible Cause
Check the control power connection on the A1 and A2 terminals of the
E300 Control Module.
This is a normal power-up sequence.
Check the Ethernet scan list for the correct scanner configuration.
Reset the E300 EtherNet/IP Communication Module or verify the validity of the data in the
configuration assembly.
Cycle power to the device. If the fault still exists, replace the device.
Table 47
explains the states of the Module Status (MS) LED of the E300 DeviceNet
Communication Module.
Table 47 - DeviceNet Communication Module Status Troubleshooting
Possible Cause
Check the DeviceNet control power on the A1 and A2 terminals of the E300 Control
Module.
This is a normal power-up sequence.
The E300 Module is in Program/Non-run Mode where no I/O connection exists or an I/O
connection exists while not in Run Mode.
The E300 Module is in Run Mode where I/O connection(s) is in Run State.
The E300 Module has been mis-configured and results in a fault condition.
The E300 Module has become inoperable due to a defective and/or intermittent
component within the unit. In most instances, activating the Trip/Reset button will not
remove this fault condition and the only way to recover from this condition is to replace
the E300 module or identify/replace the faulty component(s). In some scenarios, pressing
the Trip/Reset button may clear this fault condition. In this case, the cause for the fault is
most likely to be environmentally related and therefore component replacement is not
required.
