4.2 FC1: Hardware

The FC1 flow computer consists of a rack-mountable card cage with an
operation panel on the front side.
At the rear side, the compulsory CPU board additionally offers one network
LAN interface and two serial RS232/RS422/RS485 interfaces (COM ports).
These interfaces are typically intended for the connection of gas quality
measurement devices or other devices equipped with a protocol interface.
Several different I/O boards can be mounted from the rear side. The FC1
device is available in two housing widths, i.e. with a housing width of 1/3 for
up to four process boards or a housing width of 1/2 for up to seven process
boards. The I/O board configuration is variable; Table 6 shows an overview
of all available I/O boards.
In principle, all board types can be mounted in any slot. There is a restriction
for MSER4 and ESER4 boards only: In case of a device with a housing
width of 1/3, only one MSER4 or ESER4 board can be mounted in slot 4.
A device with a housing width of 1/2 can contain up to two boards of MSER4
or ESER4 type (in slot 6 and slot 7).
