CCW - Using constants with compare instruction blocks

Hi,

Have done a few programs with CCW and am slowly getting my mind around it. Previously I have used compare instruction blocks to start drives based on the values of a startup timer. To do this I used the timer address for i1 and then used "#T30s" for i2. This meant that when the timer value was greater than 30 seconds then the compare instruction would become true and the drive would start.


This time I am using an analog input for i1 (0-4000) and need to put a constant into i2 but am not sure of the correct syntax. Can anyone help me out?

Thanks

Is (0-4000) the raw value of what input?? You just have to make sure i1 and i2 are the same data types.

You could convert the analog input to a real value and then use your trigger point (i2) as a real value - example 1389.0.

Yes the 0-4000 is a raw value. I will try converting it to real number and see how that goes. Thanks.

Here's a sample of how I might have done it.

Thanks for that. It worked fine once I converted it to a real number.
