842E-SIP? Shouldn't you be using a multi-turn encoder for this, rather than a single turn? I mean, you can use a single turn and handle the rollover in the PLC if you want, provided it's rotating...

If Chris' post is correct, perhaps you could within your UDT create an expression BOOL tag, and put the expression in there. Then bind your enabled tag property to that expression tag?
