4.6.2 Hardware test
1 In [Switch setting for I/O and intelligent function module] of GX Developer, set
"Mode setting" to "Hardware test". (Switch 1: 0001h)
2 Match the other intelligent function module switch settings to the setting contents
used.
1 Set the programmable controller CPU to STOP status.
2 Reset the programmable controller CPU.
3 After the programmable controller CPU is reset, the following hardware tests are
executed automatically.
4 During the test, the ERR. LED flashes.
1) ROM check
Reads the ROM data and checks the sum.
2) RAM check
Reads the test data written to the RAM and checks the consistency.
3) Switch setting check
Checks that the intelligent function module switch settings are set within the
allowable range. However, the Switch 1 "Mode setting" is not tested.
*1 For a MELSEC iQ-R series system with an MES interface module, do not use the system monitor
of GX Works3 during the hardware test. It is not necessary to use the system monitor of GX
Works3 during the hardware test.
1 Check the ERR. LED status to see the hardware test result.
ERR. LED status
OFF
ON
2 When the test is completed normally, set the "Mode setting" to "Online" with
[Switch setting for I/O and intelligent function module] of GX Developer and reset
the programmable controller CPU. (Switch 1: 0000h)
3 When the test has failed, check that the switch setting is correctly set, and
conduct the hardware test again.
If an error occurs again, a possible cause is the hardware failure of the MES
interface module.
Please consult your local Mitsubishi representative.
