Hardware Features

Indicator Name and Description
Power-up, Major Hardware Fault, or the
channel is commanded to OFF.
The module is just powering up and not
initialized yet or there is a major hardware
OFF
fault causing the module to be held in reset
by the PLC. LED control is not possible for
this condition and will remain off. If the
module has already successfully entered run
mode than the channel may just be OFF.

Channels are all outputs. To actively control the state of the outputs, you must set
up a program within the PLC and transition the Controller to Run mode.

1.3.1 LED Blink Codes

The firmware uses the following LED blink codes to show the state of the
outputs. All 32 LEDs are yellow.

1.3.2 1.1 LED Operation

Once the PLC is in Run mode, any module channel that is set to the ON state,
shows a solid yellow LED for that channel. If the output is set to the OFF state,
the LED for that channel will be off.
Table 1-4 LED Blink Codes
Resolution
There are three likely conditions when the
channel LED is OFF:
•
The module is just powering up
and not initialized yet.
•
The output channel is set to
disabled (off) by the user when the
controller is in Run mode with no
fault occurring.
•
There is a major hardware fault
that is causing the module to be
held in reset by the controller. LED
control is not possible for this
condition and will remain off.
Once this happens, the controller
transitions to Program mode and
the module is not transmitting
output(s) as a device protection.
If a fault occurs, try to power cycle the
entire system to clear the fault indications
shown on the controller and CCW
program. If you cannot clear the fault, the
module will have to be replaced.
