Option LED Display
The option has two bicolor, red/green LEDs: one for Module Status (MS) and one for Network Status (NS).
The operational states of the LEDs after completion of the DeviceNet power-up diagnostic LED sequence are described
in
. Wait at least 2 seconds for the power-up diagnostic process to complete before verifying the states of the
LEDs.
Table 3 Option LED States
Power-Up Diagnostics
An LED test is performed each time the drive is powered up. The initial boot sequence may take several seconds. The
option is successfully initialized when the LEDs complete the diagnostic LED sequence. The LEDs then assume
operational conditions shown in
.
