today I was running a machine and I tried to change a timer value while the program was running. To change the timer value I had to change a value in v memory that LD to a timer v memory. Well the machine went haywire and the preset to the timer started to timing UP on it's own. Needless to say the machine won't work. I reloaded the program and still that preset is moving up for no reason that I can find. the preset again is being LD to a v memory location from a v memory location. nothing was true on the rung the tmr block is on. There is nothing that I can figure triggering the preset to increase on it's own.
Has anyone ever heard of something like this happening. I left the site, I have not tried wiping the memory on the cpu, yet.
