7.5 Checking the Module Status (Hardware Test)

The hardware test checks whether or not each module works properly by itself. Always
perform this hardware test before configuring the system and for each module by itself
without connecting the cable. Otherwise, the hardware test will not be executed properly.
"CC-LINK PARAMETER ERROR" occurs when a hardware test is executed in a safety
CPU operation mode other than TEST MODE.
Execute the hardware test using the following procedure.
(1) Connect a terminating resistor
Connect a terminating resistor between safety master module terminals DA
and DB.
(2) Power on
Turn on the safety power supply module.
(3) Confirm TEST MODE
Check the LEDs on the safety CPU module to see that TEST MODE is active.
(Confirm that the "TEST" LED is ON.)
Not in TEST MODE
(4) Change to TEST MODE
Use GX Developer to change the current operation mode to TEST MODE.
For how to change to TEST MODE, refer to the QSCPU User's Manual
(Function Explanation, Program Fundamentals).
(5) Conduct a hardware test
In GX Developer, select "Parameter" - "Network Parameters" - "CC-Link" and
open the "Network parameter CC-Link list settings" screen. Set "Hardware
test" in the mode setting and perform Write to PLC. Turn OFF and ON the
PLC, or reset the safety CPU module and then cancel the reset status. Then,
conduct a hardware test.
