In the manual - they say you can 'and' and 'or' and such.. You need a , then
the operator.

Oh I misunderstood your question. Yes I think a single variable comparison
block is limited to only a single comparison of a variable to one constant or
another variable. I am surprised that it worked with the last two compares
combined into a single block. So for your row of logic below I
The CL program I have running on our machine has at least 20 different variable
comparisons. There are even 6 in a single rung with 4 or branches and 2 pairs
anded together. So yes you can use more than two, and as far as I know there
is no practical limit.

I'm pretty sure no. I thought the machine I have using CL uses several more
than 2 compares, but I'll have to check (it was several years ago I wrote that
ladder.)
