1. Overview

● The Multi-monitoring function allows users to display and collect “measured input value”, “current setpoint”, “control output” and “alarm generating state” of GREEN Series controller as trend data. The GREEN Series controllers connected to the personal computer can be detected automatically by Automatic scan, and the trend data is displayed on a personal computer screen. The data of a maximum of 16 loops (*1) can be collected at the same time. A maximum of 16 trend data can be displayed on a chart screen. Trend display cycle: 1 to 3600 sec (variable) Trend display times: 65000 times (fixed regardless of a trend display cycle)

● The Panel view shows measured input value, current setpoint, control output and alarm generating state of the connected loop.

● The collected trend data can be outputted as a CSV format so that commercial spreadsheet software like Microsoft Excel can treat.

● The saved trend data can be read out and displayed as trend graph.

● T uning can be carried out for every connected loop. Auto-tuning, change of PID param-

eters, change of operation mode and the like can be carried out.

*1: One unit of the following controllers uses two loops: UT750/UP750 cascade control, dual-loop control, temperature and

humidity control and cascade control with two universal inputs, UT550/UT551/UT520/UP550 cascade control.
