Moving 32Bit Floating by 2 integer numbers in RSlogix5

[georgeofthejungle02]

Hello:
I have a floating number, and I would like to use an existing msg block that have many spare integers to transfer this info from one PLC to another. But how do I break up the floating number into two 16 bit words and then put them back together in the end? (ie move F8:38 by breaking it into N11:400 and N11:401)
Does anyone know how to do this?
Thanks.
George

Use the copy instruction (COP). The copy performs a byte by byte copy without doing any conversion. Remember that the length field is relative to the destination data type. So when you are copying the float to the integers the length is two. When you copy the integers to the float the length is one.
