Basic Functions of the GX/GP
The basic functions of the GX/GP includes measurement, recording, display, storage, and
data utilization.
In addition, loop control and program control (/PG option) become possible by installing the
PID control module.
This section provides an overview of each function.
Measurement
The GX/GP can measure signals from thermocouples, RTD sensor input, DC voltage, On/
Off (voltage-free contact, level), DC current (mA), pulse input and resistance. (The input type
varies depending on the module type.)
The GX/GP samples the signals received through the input modules at a specified scan
interval and performs A/D conversion. These values become the measured values of each
channel.

Recording
Data Type
The GX/GP can record two types of measured data: display data and event data (event
only when the measurement mode is set to High speed or Dual interval).
Data sampled at the scan interval is recorded in the internal memory as measured data for
each specified data type (display data and event data).

Dual interval
When the measurement mode is Dual interval, measured data of the channels assigned to
measurement groups are recorded in the internal memory by each measurement group.
