IOLink function blocks
Two IOLINK function blocks, which represent the 2 physical IO links on the C300
Controller IOTA, provide the user-configured I/O Link interface to support
communications with Series 8 I/O modules. Each IOLINK is configured to support
Series 8 I/O modules or 'No Link' if no I/O control is required. Each IOLINK supports
redundant and non-redundant communications.
I/O modules supported by the C300 Controller
The C300 Controller supports Series 8 I/O modules. Series 8 I/O modules are connected
to the C300 by a pair of I/O Link Interfaces. Two IO Link interfaces, which are
redundant, provide connection between the C300 controller and associated I/O modules.
Each IO links can be configured to support Series 8 I/O modules.
Refer to the Series 8 I/O User’s Guide for listings of the supported I/O modules.

Identify C300 Controller components
Table 1 identifies the C300 Controller components and its associated components. The
C300 Controller supports non-redundant and fully redundant operation. Redundancy is
built in to the controller, so that just adding another controller and a redundancy cable; a
redundant controller pair is achieved. Note that the '8C' or CC designation on the model
number indicates the printed wiring boards are conformally coated for additional
protection from the environment, (8U or CU= uncoated).
Table 1 Series 8 Hardware components
A distributed process controller and I/O
gateway for the Experion LX system.
Module contains printed circuit
assemblies, status indicators and a
display, inside in a plastic housing.
Module mounts to its Input Output
Termination Assembly (IOTA).
Provides the connection point for the C300
Controller module and all cable
terminations to the controller, (FTE,
IOLink, Redundancy, Battery and Time
Source cable terminations). Provides 24
Vdc power distribution to the controller
