Logo!

Hey there.
I am using V7 of Soft Comfort to program a LOGO! I am wondering if there is any function comparable to an "EQU". instruction in other manufacturers PLCs. I am trying to turn on a output based on the position of a count up. Any suggestions?


Thanks for the help in advance.

Can't you use the analog comperator, and use the counter value as reference?

I may very well be able to. I was simply looking for a way to do this. I would have never thought of using an analog instruction to compare a counter to another value. I will give this a try here in a bit.

Thanks for the advice.

So I believe that this Analog Comparator will do as I want. The issue I have now is trying to connect the block to the rest of the circuit. It gives me the yellow message that says Incompatible Connectors. Is there something I need between my left power bus and the block? I have tried connecting to both the Ax and Ay terminals. I have my sensor: set to NO SENSOR and my refrence is set to my counter and the threshold is a value of one.

Should mention this is an OBA7 device!
Any ideas?

Thanks

are you working with ladder or with blocks? better use blocks.now for the Incompatible Connectors you can use M blocks as memory bits.

Hello there.
So I have been struggling with this a little. My goal is to turn on output 5 for ten seconds. then off for ten seconds. Then turn on output 6 for ten seconds then off for ten. Then turn on output 7 for ten seconds then off for ten. Repeat!!
I find this very simple in AB but with LOGO I am stuck. As you can see I want to increment counter C004 every time the counters cycle. Based on the position of the counter turn on an output. IE: Count at 1 turn on output 5, count at 2 turn on output 6, count at 3 turn on output 7 then reset the counter. One has mentioned to me to use the Analog comparator but I can't get it to work. If anybody cares to look at my quick program here and criticise it would be greatly appreciated.

Thanks!

Bump!
