(4) After you successfully download the hardware configuration to the CPU module, the BUS FAULT LED
indicator on the CPU module is OFF. Close the HWCONFIG window. If the BUS FAULT LED indicator
on the CPU module is still ON or blinking, the CPU module is in an abnormal state. Make sure the
actual hardware configuration is the same as the hardware configuration in the HWCONFIG window,
and refer to the operation manual for more information about eliminating the error. Refer to Chapter 8
for more information about HWCONFIG.

Connection Test
After you download a program to a PLC, you can monitor the execution status of the PLC through ISPSoft.
ISPSoft provides two monitoring modes; device monitoring mode and program monitoring mode.
Monitoring mode Description
Device monitoring mode
You can monitor the status of the devices in the PLC through the monitoring
table. In this mode, ISPSoft updates only the status of the devices. The
current program in ISPSoft does not have to be the same as the program in
the PLC.
Program monitoring mode
In this mode, the operating status of the program is displayed in the program
editing window. The present program in ISPSoft must be the same as the
program in the PLC.
*. You can enable the device monitoring function without program monitoring; however, if you enable the program
monitoring function, the device monitoring function is also enabled.
