I am converting a rslogix 500 program into a Studio 5000 program but some of the instructions are not the same. For instance in rslogix 500 I have source that is RTC:0.HR and I am not sure how to convert that since I cant find an RTC instruction in the STudio 5000. Could someone please help me?
 
RTC:0.HR

I believe this is not an instruction but an address. Note the colon ( : ) and dot (.) delimiters. It looks like a Real Time Clock address
 
Sorry I dont know how to do ladder logic on here but your right... it is actually a GEQ instruction with source (A) showing RTC:0.HR <10 and/or source (B) showing 5

and then the rest of the rung goes on.
