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.
