4.2 PGM assembly
The PROFIBUS Gateway Module consists of an Input/Output Terminal Assembly (IOTA) board and the PGM
module which is housed within a plastic cover and is mounted onto the IOTA board. The PGM assembly is
installed in a control cabinet on vertically-mounted channels specifically for Series C control hardware. The
following table provides information on the PGM IOTA board.

4.2.1 CF9 control firewall - 9-port control firewall (CF9)
In the control cabinet, Control Firewall assemblies (CF9) provide connection of control hardware (PGM and
C300 Controllers) to the FTE network. STP CAT5 cables connect the FTE-capable control hardware to the
Control Firewall IOTA. Two Control Firewall assemblies are required to provide network redundancy, (one CF9
supports the FTE "A" segment and the second supports FTE "B" segment). Eight ports on each control firewall
provide connection for up to eight FTE nodes. A 9th port provides an uplink to the supervisory FTE network
and level 2 control.
See the Control Firewall User's Guide for details about the Control Firewall installation.
