    First of all, you need to Read Holding Registers (R.H.R #3), not Read Input Registers (R.I.R #4). Also, you can read and write bits (coils) directly using Read Coils #1 and Force Coils #5 or #15. But the simplest method when you are communicating between two Unitronics Vision PLCs is to use the FB Read/Write Mixed Data. This FB allows you to enter a mix of operands and read or write them directly using a single function call.
