to prevent signal reflections potentially interfering with
communications.
For RS485 (2-wire, point-to-point or multi-drop), the termination
should be placed at each end of the network. Connect the “T” terminal
to the RS485 B- to enable the termination at CN100 Controller RS485
port side, and refer to third-party devices user manual for information
about termination.
IO Link Ports
The I/O Link is a redundant serial communications subsystem that is
the interface between the CN100 Controller and its Series C I/O or
PM I/O. It is a multi-drop network operating at 750 Kilobits per
second (Kbps) for Series C I/O. The CN100 Controller has one pair of
I/O Link ports identified as I/O Link 1 (IOL1). Each port is
configurable to interface with either I/O Link speed. You cannot mix
I/O of different speeds on the same link.
Connecting with Wireless I/O
To connect Wireless I/O, a Honeywell Field Device Access Point
(FDAP) is connected to the controller through Ethernet. A Honeywell
FDAP can connect with non-redundant controller directly while to
connect with a redundant controller, a switch is needed.
ATTENTION: Confirm the location to be non-hazardous prior to
adjusting the switch.
ATTENTION: Veuillez-vous assurer que vous êtes dans une zone
d’atmosphère non explosive avant d’ajuster le sélecteur.
n For detailed and complete information about installing the FDAP,
see the Field Device Access Point User’s Guide.
n For the topology of FDAP and field devices in the system, see
"Network Security" in the Experion Network and Security Planning
Guide.
n For how to configure wireless I/O, see Control Builder Users Guide
for details.
