Function Block Programming - Omron PRT1-SCU11 Operation Manual

B-1 Introduction
In order to facilitate the data transfer to and from Temperature Controllers from a CS1/CJ1W-PRM21 PROFI-
BUS-DP Master via the PRT1-SCU11, OMRON provides a number of PLC Function Blocks. These function
blocks can be used in the CS1/CJ1 PLC program to assemble the output data or extract the input data from the
CS1/CJ1W-PRM21 PROFIBUS Master I/O data areas. This appendix describes these function blocks.
Note Function Blocks are only supported by CX-Programmer version 5.0 and higher.
B-2 Basic / Extended Function Blocks
A total of 10 function blocks are provided for the basic and extended I/O configuration blocks for the E5_N,
E5ZN and E5_R Temperature controllers. The table below lists the specifics of these function blocks.
Item
Basic function Writes the SV/Operation command and reads the PV/MV/Status/Operation Executed word.
