Title: PLC pause error!!
Post by: shyampras on May 03, 2007, 11:12:02 PM

Hi,

One of my T100MD 888 PLC has PAUSE LED "on" since power up. I am unable to connect to it through Trilogi to reset it.

Need immediate help...

Reards,

Check if the DIP switch #4 has been turned ON. If so the PLC powered up with CPU in PAUSE state and COMM1 is set to 9600 bps.

If the DIP switch #4 is not turned ON but PLC is paused, then there could be a problem in the program inside the EEPROM. You can turned on DIP switch #4, power ON reset the PLC and set  TLServer COM port to 9600 bps. Transfer a blank program to the PLC, then turned OFF DIP switch #4, power reset again and the PLC should now work - TLServer need to be set back to 38,400 bps after this.
