Rosemount 2410 Tank Hub
1.1.1 Enraf system characteristics
A typical Enraf tank gauging system consists of a number or field devices such as level,
temperature and pressure devices. These devices are connected to a host computer via a
Communication Interface Unit (CIU).
Different versions of the CIU:
CIU 858
CIU 880 Prime
CIU 880 Plus
The host computer can either be a PC with Entis monitoring system, or an Enraf Microlect
station.
The Rosemount 2410 Tank Hub supports the Enraf GPU protocol. It can therefore be
connected directly to Entis/CIU systems using the GPU protocol.
Enraf GPU communication parameters
Start bits: 1
Data bits: 7 (ASCII)
Parity: Odd
Stop bits: 1
Baud rate: Selectable 1200 (default)/2400
Enraf gauges for emulation
The Rosemount 2410 can emulate Enraf gauges with Type of Instrument (TOI), B or C.
