3.1.Hardware Troubleshooting
During initialization, the Profibus DP driver checks for the
3.2.SST Profibus card LEDs
There are two LEDs on the SST Profibus Card. When operating normally the COM LED should remain solid green. Any communications errors will cause it to flash red for at least one second. The SYS LED shows the status of both the master and slave. If using either the slave or master, the SYS LED will show green if all is ok, amber if all is ok but the bus is running in program mode, and red if there is a problem. If running both master and slave, the LED will sequence through the master status, the slave status and then off.
