I am using a T100MD 16-16 to run a composites oven. I upload a new file quite often to change max temps, ramp times, etc. Lately, the plc has caused some errors, random stuff like overtemp, or not finishing it's cycle, miscount on cycle times, etc. Nothing has changed with the program really, I just change a couple of parameters in it to modify the output, and it has always been very reliable in the past years. Can the PROM become corrupt over repeated downloads? I am using Trilogi in DOS, from Windows 98, is there something in this setup that could corrupt the compiler?
