PLC-based Process Control Engineering Guide
PLC-based process controller is a process control system which has the base of SYSMAC SC/CJ series. It can be adopted for both loop control which controls analog signals and sequence control
which mainly handles contacts. By combining a loop controller and process I/O units, loop control functionality can be added onto the PLC, maintaining the basic PLC function.When developing a system, operating environment,
such as initial setting of PLC is required, so that the PLC can operate. Then, utilize CX-Process, the tool software of loop controller to build the system. HMI can be selected
from the Touch panel (NS series), special monitoring software CX-Process Monitor Plus, and general HMI software, depending on the application. This manual describes the procedure to build a PLC-based process control system.The engineering method may differ depending on the devices. In this manual, an example system is built on the Loop-control CPU Unit (CJ1G-CPU**P) and HMI recommended by Omron is combined.
Section1. outlines the features and mechanism of the Loop Controllers
Section2. describes the procedure to build an example system on the Loop Controller.
Section3. provides the names and functions of parts, and provides other information required toinstall
and operate Loop Controllers.
Section 4. describes application cases of PLC-based Process Control system.
