Hi, I am learning how to use our LADDER III software. I am writting a small program and I need a .5s flashing bit. Where would I find this 0.5second flash bit for Fanuc. Also, how to you set the preset time of a timer? For example I am using a SUB 3 timer. :rainfro:

Sub3 timers are set in the PMCPRM page under TMR. Sub24 timers are "fixed" timers in the sense that you have to physically edit the ladder to change the timers preset.

If you're trying to get a bit to flash to do something like a red stack light flash you can do whatever bit you're using to activate the output and run it through a timer, and have the output reset its self. It would look something like this.

Flashon--SLRED------------------------------ SLRED
I I--------I/I----------Sub3 TMR1---------------O



I had to put the dashes between my comments because the post kept auto formatting to the left margin.

My example is wrong. That would essentially turn the stack light on for about a milisecond, and then shut it off for the timer's preset. The correct way would be

Flashon-------SLRESET-------------SLRED
---I I-----------I/I-----SUB3 TMR1---O---This line is the amount of off time.

SLRED--------------------------SLRESET
--I I----------Sub3TMR2-------------O---This line is the amount of on time.
