Introduction
A Rosemount
™
2460 System Hub can emulate an Enraf 858 CIU
(1)
on any of the available host ports
(2)
.
With Enraf CIU 858 emulation, you can use a Rosemount 2460 System Hub together with an existing
host control system. The system hub is transparent to the old host, passing information along to the field
devices so the user will not even notice that the old CIU has been replaced.
This section describes how to configure the Enraf server functionality in Rosemount TankMaster.
The Enraf server ports can use RS-232 or RS-485 communication interface. However, note that the
RS-232 interface can only be used on Port 7.
