I'm using a DL06 PLC with DirectSfot32.

Now maybe I'm completley missing something obvious here, but how do I setup the timers?

So, let's say I have a timer, T0, I can set a K paramter. What is this, and how do I apply a 'real ' time to this?

i.e. I want a 3 second timer (fixed, not variable, always 3 seconds) - how is this done?

I'm just baffled, but I can't seem to find where I would set this in DirectSoft.

Thanks in advance for any help.

You start by making a rung with a conditional input. Go across to a TMR box. Call it T0

When the input is true, the timer runs. The value of the timer is in tenths of second, (BCD). For 0.01 sec count use TMRF. TO view the count look at TA0 (This is a word for TMRs. I can't remember for sure, but I think if you use TMRF, then TA0 is a double word. You can only use every other timer if you are using TMRFs.)

If the count of the timer is less than the Kvalue that you have in the box, then the status bit (Tx) is false. If the count is Greater than your Kvalue, the status bit is true.

When the input to the timer is false the timer is reset to zero and does not run. (consequentially T0 would be false if input is false.)
