The Experion Series 8 C300 controller forms the heart of the Experion control system and deterministically executes control strategies, batch operations, interfaces to local and remote I/O and directly hosts custom programmable applications. The compact controller design does not require any additional Interface / communication modules and all control execution and

communications are contained in the controller module.

The C300 controller runs the filed proven, deterministic Control Execution Environment (CEE) which is the core C300 software that provides powerful and robust control for the distributed control system (DCS). The control strategies are configured and loaded to the C300 controller through the Control Builder, an easy and intuitive engineering tool.

The C300 Controller is constructed using the Series 8 form factor that employs an Input Output Termination Assembly (IOTA) and an electronics module which mounts and connects to the IOTA. One C300 Controller module and its IOTA contains all of the control and communication functionalities. The C300 IOTA contains only passive devices such as

FTE address switches, FTE cable connectors and I/O Link cable connectors. Figure 1 below depicts the IOTA

components.

The C300 Controller may operate in both non-redundant and redundant configurations. Redundant operation require a second identical controller with its own IOTA and connecting redundancy cable. The C300 Controller supports Series 8 I/O modules. Two IO Link interfaces, which are redundant, provide connection between the C300 controller and

associated I/O modules. The IO Link interface connectors are on the C300 IOTA.

C300 Controller Specifications

C300 Control Execution Environment (CEE):

The C300 CEE creates an execution and scheduling environment for Control Modules (CMs) and Sequential Control Modules (SCMs) to execute control strategies configured by users. It enables peer-to-peer communications with other C300 controllers and communication modules like Foundation Fieldbus and Profibus. Engineers configure control strategies using the Control Builder Engineering environment, which offers a graphical engineering environment for system configuration and control strategy creation. Users can set the minimum execution rates for C300 CEE-based control strategies at 50 msec.
