US Version. Seventh edition, June 1995
Installation Manual
A host computer can be connected either to a PC with OPI Soft-
ware or directly to the Field Communication Units (FCUs).
The TRL/2 system can be connected to all major DCS systems,
such as Foxboro, Honeywell, Rosemount and Yokogawa. New
interfaces can be developed on request. For a complete list of the
available interfaces, please contact Saab Tank Control or one of its
representatives.
8.1
Connect to the FCU for Quick Updates
When a host computer is connected to one or several FCUs, mea-
sured data such as level, average temperature, pressure, etc. can be
transferred to the host system. If the host system has inventory
functions, a connection directly to the FCUs is recommended.
8.2
Connect to OPI/2 for Inventory Data
When a host computer is connected to the OPI/2, calculated data
such as volume, mass and density can be communicated in addi-
tion to the measured data mentioned in chapter 8.1 above.
