HONEYWELL 8C-PCNT01 51454363-175 -1 Series 8 Controller and I/O Specification

The Experion Series 8 C300 controller forms the heart of the Experion control system and deterministically executes controlstrategies, 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 andcommunications are contained in the controller module.

The C300 controller runs the filed proven, deterministic Control Execution Environment (CEE) which is the core C300software that provides powerful and robust control for the distributed control system (DCS). The control strategies areconfigured 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 IOTAcontains all of the control and communication functionalities. The C300 IOTA contains only passive devices such asFTE address switches, FTE cable connectors and I/O Link cable connectors. Figure 1 below depicts the IOTAcomponents.

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

The C300 CEE provides an execution and scheduling environment in which Control Modules (CMs) and Sequential Control Modules (SCMs) execute user-configured control strategies. The CEE also support peer to peer communications with other C300 controllers and communication modules like Foundation Fieldbus and Profibus. The C300 CEE is configured using the Control Builder Engineering environment. The Control builder provides a graphical engineering environment where engineers can configure the Experion system and create control strategies by using the various function blocks available in the Library. The C300 CEE based control strategies can be configured with minimum execution rates of 50 msec.

Overview and Features Series 8 features an innovative design that supports enhanced heat management. This unique look provides a significant reduction in overall size for the equivalent function. Both Series 8 IOM and IOTA are available with Conformal Coated feature. The term ‘Coated’ stands for hardware with conformal coating material applied to electronic circuitry for protection against moisture, dust, chemicals, and temperature extremes. Coated IOM and IOTA are recommended when electronics must withstand harsh environments and need

 to have added protection. The unique features of the Series 8 I/O include: • I/O Module and field terminations are combined in the same area. The I/O Module is plugged into the IOTA to eliminate the need for a separate chassis to hold the electronics assemblies • Two level “detachable” terminals for landing the field wiring in the enclosure, providing easier plant installation and maintenance • Field power can be supplied through the IOTA, with no need for extra power supplies and the associated craft wired marshalling • Redundancy is available directly on the IOTA without any external cabling or redundancy control devices, by simply adding a second IOM to an IOTA • The innovative styling is one of its unique features. This styling includes features to facilitate the effective use of control hardware in a systems environment. These features include: o Vertical mounting for more effective wiring since most field wiring applications require entry from the top or bottom of the systems cabinet o An “information circle” for a quick visual cue to draw the Maintenance Technician’s eye to important status information o “Tilted” design for effective heat management within the cabinet enclosure. Since Series C allows for a significant increase in cabinet density, an effective heat management system is critical for high systems availability o Input and output circuits are protected from shorts to alleviate the need for in-line fusing, reducing installation and maintenance costs Series 8 IOTAs combine multiple functions into a single piece of equipment: o Single and redundant configurations o On-board termination of process signals o On-board signal conditioning o On-board connection to appropriate networks (FTE, I/O LINK) o Field power distribution without external marshalling o IOM plugs into the IOTA and receives power from the IOTA o The IOTA receives its power through cables from header board I/O Module Functions 

• High Level Analog Input /HART Input Module (16pt) 

The High Level Analog Input Module supports both high level analog and HART inputs. Analog inputs are typically 4-20mA DC for both traditional and HART devices. HART data can be used for status and configuration. HART data, such as the secondary and tertiary variables, can also be used as process control variables. Two versions Single ended and Differential type are available.
