Direct Logic PLC Help

[edward.ortiz]

I have a DL205, dl250-1 cpu and a ecom100 module. I have a 16bit register utlizing bits 0-10. I am trying to figure how to set up a sequence for the bits. I want to use a bit to activate a valve for minutes, then another bit for 10 minutes, then the 3rd bit for then minutes, then the 4th bit for 10 minutes. A total of 40 minutes. How do i set this up in DirectSoft?

Why not take each bit and add the corresponding time to and internal memory location? Then use that memory location for the timer on the valve. Am I missing something in the sequence that you are look for?

Can you please elaborate a bit more on the steps to do this

Use each bit to Add (ADD) the constant for that bit to an internal memory location. ( Example: V0)
Then use the Timer (TMR) instruction to control the valve.

Note: You might have to use the Positive Differential (PD) to avoid adding the variables every scan. Or if you do not know when to trigger, then move the result to another internal memory location and reset the previous.

I have attached a link to the programming manual.
