Hardware Test
This section describes how to perform a test related to hardware, such as a ROM/RAM of the FX5-ENET/IP.
• During the hardware test, values in the buffer memory cannot be referred from the GX Works3 or the
program.
• Do not change the operating status of the CPU module during the hardware test. If the operating status of
the CPU module is changed, the module major error occurs in the CPU module.
Operating procedure
1.
Set the FX5-ENET/IP to the hardware test mode using the GX Works3.
[Navigation window] [Parameter] [Module Information] [FX5-ENET/IP] [Indispensable Setting] [Mode
Settings] Select "Hardware Test"
2.
When a cable is connected to the Ethernet port of FX5-ENET/IP, disconnect it.
3.
Set the CPU module (FX5-ENET/IP) to the STOP state and write parameters.
4.
Power off and on the system or reset the CPU module (FX5-ENET/IP).
5.
The hardware test is automatically executed.
The following table shows the LED indications of the FX5-ENET/IP for the hardware test.
Status
During hardware test execution
Hardware test completed successfully
Hardware test completed with an error
6.
When the test completed successfully, set the FX5-ENET/IP to online mode using the GX Works3.
[Navigation window] [Parameter] [Module Information] [FX5-ENET/IP] [Indispensable Setting] [Mode
Settings] Select "Online"
Write parameters and power off and on the system or reset the CPU module (FX5-ENET/IP).
7.
When the test completed with an error, check that adequate measures to reduce noise are taken for the programmable
controller system and retry the hardware test. If the test still completes with an error, a hardware failure may have
occurred on the FX5-ENET/IP. Please consult your local Mitsubishi representative.
