Data Reading; Direct Data Reading - GE Hydran 201i Instruction Manual

• A modem can be connected to any Hydran 201i System in a local network.
The modem is typically installed in any of the local network's Hydran 201Ci
Controllers.
• The modem of the local network is connected to a telephone line.
• The host computer equipped with a modem and the Hydran Host software
communicates with the Hydran 201i System network(s), thus simplifying the
monitoring process.
• Each power station can have its own, independent network.
• The station can be entirely automated (unmanned).

12.2 Data Reading

Data (gas level, hourly and daily trends, alarm messages, etc.) can be read as follows:
• Direct reading using a Hydran 201Ti, a Hydran 201Ci controller, the Hydran
Host software or Perception software: See Section 12.2.1.
• Reading of the Hydran 201i System's historic data (using the H201Ti, the
Hydran Host software or Perception software): See Section 12.2.2.

12.2.1 Direct Data Reading

Data can be read directly as follows:
• With the Hydran 201Ti: Its local user-interface includes a six-key keypad and a
2-line per 16-character display. For details, see Chapter 5.
• With the Hydran 201Ci-1: Its local user-interface includes two illuminated
push-buttons and a display, all mounted on the enclosure's door. Note that
the H201Ci-1 does not provide the cause of the alarm.
• With the Hydran Host software: A host computer running General Electric's
Hydran Host software remains the easiest way to read data when the H201Ti
is set to Hydran protocol. The host computer screen provides an interaction
far superior to the one of the H201Ti's local user-interface. For details, see the
Hydran Host Software Manual. The windows Network Survey and Real Time
Log Set-Up can be used to monitor the data of up to 128 H201Ti's.
• With the Perception software: A host computer running General Electric's
Perception software remains the easiest way to read data when the H201Ti is
set to ModBus protocol.
superior to the one of the H201Ti's local user-interface.
