Module and Channel Status Display

At a Glance

The discrete I/O modules are equipped with a display block featuring LEDs that displays the module’s channels status the overall module status.

Description

The following table explains how the LEDs located on the discrete I/O display block operate.

LEDs	Continually Lit	Flashing	Off
RUN (green)	module operating normally	N/A	module inoperative or off
ERR (red)	internal event: Module analysis needed	Communication loss between the discrete module and the CPU	no detected internal error
I/O (red)	external event: overload, short circuit, sensor/pre-actuator voltage error	Terminal block incorrectly wired	no detected external error
+32 Green	selection of channels 32 to 63	N/A	selection of channels 0 to 31
Channel status	channel at 1	channel error, overload, short circuit, or open wire detected⁽¹⁾	channel at 0
(1) When channel status is open wire detected, the flashing timing is the following: 64 ms ON 64 ms OFF 64 ms ON 2000 ms OFF

NOTE: The +32 LED is only present on the 64-channel modules. It is enabled/disabled with a push-button located on the top of the module. By default, the first 32 channels are displayed.

NOTE: For a mixed input/output module, the first line of channel status LEDs represents the inputs (for example, for a mixed 16 input/16 output module, LEDs 0 to 15 represent the inputs and LEDs 16 to 31 represent the outputs).

NOTE: After the sensor power outage, the I/O (red) LED of the following modules switch on and the last recorded position of the sensor is displayed by the input channel status LED's:

BMX DDI 1602
BMX DDI 1603
BMX DDI 1604T
BMX DDI 3202K
BMX DDI 6402K
BMX DDM 16022
BMX DDM 3202K
BMX DDM 16025

WARNING

CHANNEL LED INFORMATION NOT MATCHING SENSORS POSITION

After a sensor power outage:

The I/O error LED is on
Do not take into account the input LEDs information (they show the last recorded position of the sensors, not their real positions)
Check the real positions on the sensors.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Display Panels

When a voltage is present on an input or output, the corresponding LED is lit.

Display of internal or external events is only effective once the module has been configured. After powering-up or a cold start, all the LEDs flash twice (for 2 seconds) to show that the module is operational. When an event is detected, the channel status is recorded until the cause of the event is cleared.

There are several display blocks depending on the type of discrete I/O module.
