Hardware Test

This section describes how to perform a test related to hardware, such as a ROM/RAM of the FX5-ENET.
• 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.
