Title: Lost comm after program load T100MD+
Post by: raan on August 09, 2008, 06:30:44 PM

I downloaded a program to the plc and after resetting the the plc the run error and pause light are now flashing red and I am unable to communicate with the plc. I suspect  that some cust functions that I redid to increment the two pwm outputs upwards may have caused some sort of overflow errors. Please advise

I was able to re-establish communications by using dip switch 4 and re-booting  the PLC. I went back to the old program and all is fine.
