PLC 5 High/Low select function?

[Ideasworking]

Hello,

I need to compare two analog values and store the high or the low value. Does the PLC5 have an instruction like this? If not are there any other ways to determine the high or low value of two analog values?

Thanks,
Lou

Just in case anyone cares... What I did was use four compares and four moves.

For the high select, I have two rungs; rung 1 comares A to B, if greater the move puts the A value to a new address (N33:27). Rung 2 compares B to A, if greater the move puts the B value to the same new address (N33:27).

The low select looks pretty much the same but the new address is N33:28

Hope this helps someone else.
Cheers!
Lou

Couldn't you get by with only two compares?
If A > B Then
move A to N7:100
Else move B to N7:100
