162 Programmable Controllers
Providing Effective Solutions by Integrating Sequence Control and Loop Control into the Same Basic
Functionality of the CJ Series
Overview
An engine for controlling analog quantities (e.g., temperature, pressure, flowrate) is built into the same CPU Unit as the engine for executing se-
quence control, delivering high-speed sequence control and high-speed, advanced analog quantity control in a single Unit.
Features
• Program graphically by pasting function blocks for PID control, square root calculations, or other functions in a window and then connect them
with the mouse.
• More than 70 types of function blocks are provided, including Bank Selector and Split Converter (for heating and cooling control), supporting a
wide array of control methods from basic PID control to cascade control and feed-forward control.
• Function blocks enable a control cycle speed of up to 10 ms. A range of control methods are supported from detailed flowrate control and pres-
sure control to high-speed temperature control.
• The CX-Process Tool can be used to open the tuning window and change parameters while monitoring PVs, SPs, and MVs.
• The Face Plate Auto-builder for NS (order separately) can be used to automatically create touch panel adjustment windows, including control
windows, tuning windows, and segment program parameter setting windows, from function block data.
