A Variety of Source Signals
The GX/GP can connect to DC voltage, TC, RTD, and
ON/OFF inputs and measure temperature, flow rate, and
other parameters. The GX/GP acquires data by sampling
input signals at the set scan interval. The shortest scan
interval is 100 ms. Up to four alarm conditions can be
specified on each measurement channel.
Expandable Module Construction
The I/O section is modular, so you can configure your
system according to the input types and number of
measurement points.

Data Storage
There are two ways to store data. One way is to record
measured data at all times (display data and event data).
The other way is to record only when events, such as
alarms, occur (event data). Measured data is saved to
the internal memory at the specified interval. Data in
the internal memory can be saved to the SD memory
card automatically or manually. Measured data can
be transferred automatically to an FTP server over an
Ethernet connection.
