Configuration Lock Indicator
Configuration lock indicator is not supported by the Logix Designer application.
Table 13 - Network Activity Indicator
State Status Recommended Action
Off No link established Establish link.
Flashing Green Transmit or receive activity None.
Steady Green Link established None.
Table 14 - Safety Input Status Indicator
State Status Description Recommended Action
Off Safety input off The safety input is off or the channel is configured for not used. Turn the safety input on or reconfigure the
channel, if desired.
Solid yellow Safety input on The safety input is on. None.
Solid red Fault detected A fault in the external wiring or input circuit detected. Check configuration, field wiring, and devices. If no
problem found, replace module.
Flashing red Partner fault detected A fault in the partner input circuit of a dual-input configuration
detected.
Check the field wiring and verify your configuration
for the partner circuit. If no problem found, replace
module.
Table 15 - Test Output Status Indicator
State Status Description Recommended Action
Off Test output off The test output is off or the channel is configured for not used. Turn the test output on or reconfigure the channel, if
desired.
Solid yellow Output on Output is on. None.
Solid red Fault detected A fault in the external wiring or input circuit detected. Check field wiring. If no problem found, replace
module. For outputs configured for muting could
indicate undercurrent or burned-out lamp.
Table 16 - Safety Output Status Indicator (1791ES-IB8XOBV4 only)
State Status Description Recommended Action
Off Safety output off The safety output is off or the channel is configured for not used. Turn the safety output on or reconfigure the channel, if
desired.
Solid yellow Safety output on The safety output is on. None.
Solid red Fault detected A fault in the output circuit was detected. Check the circuit wiring and end device. If no problem
found, replace module.
Both tags in a dual channel circuit do not have the same value. Make sure logic is driving tag values to the same state
(off or on).
Flashing red Partner fault detected A fault in the partner output circuit of a dual output configuration
was detected.
Check the circuit wiring and end device of the partner. If
no problem found, replace module.
