Honeywell CC-PCNT01 C300 Controller Module

The Honeywell CC-PCNT01 is a distributed process controller and I/O gateway for the Experion control system. It executes configured control strategies and coordinates data exchange with connected I/O and peer controllers. The module contains printed circuit assemblies, status indicators, and a display within a plastic housing, and mounts on a compatible Input Output Termination Assembly (IOTA).

Control and I/O Communication

The CC-PCNT01 supports two I/O links, allowing the controller to exchange data with connected I/O hardware. The specified link speeds are 375 Kbaud for the PMIO link and 750 Kbaud for the Series C I/O link. The supported link type and connected hardware determine the applicable communication configuration.

The controller supports a 50 ms base execution period for control processing. Configurable execution periods are also specified for Control Modules (CM), Sequential Control Modules (SCM), and related module types. These periods determine how often configured control logic executes and should be selected according to the control strategy and system configuration.

Redundancy and System Integration

The supplied specifications indicate controller redundancy support and compatibility with remote non-Series C I/O, including PM I/O or Series A I/O. These capabilities depend on the applicable Experion hardware configuration and system engineering requirements. Verify the installed controller arrangement and I/O architecture before selecting a replacement module.

The controller mounts on its IOTA, which provides the physical connection and termination point for the controller's associated connections. The IOTA is a separate hardware assembly, so the controller model and termination assembly should be checked independently during maintenance or replacement.

Time Synchronization and Peer Data Updates

The CC-PCNT01 supports Simple Network Time Protocol (SNTP) and Precision Time Protocol version 2 (PTPv2) as time sources. The specified SNTP update period is 1 minute, while the PTP update period is 30 seconds. GPS time support is listed as not available.

Peer update rates are configurable at 100 ms, 200 ms, 500 ms, or 1000 ms. This setting defines the interval at which data is updated for peer-data pull/get requests used by blocks within the Control Execution Environment (CEE). It affects data freshness and should be considered when configuring inter-controller data exchange.

Frequently Asked Questions

Q: Which I/O link speed should be used with the CC-PCNT01?

A: The specified speed is 375 Kbaud for PMIO and 750 Kbaud for Series C I/O. Select the link configuration according to the connected I/O hardware and the installed Experion system architecture.

Q: Does the CC-PCNT01 support controller redundancy?

A: Yes, redundancy is listed as supported. Confirm the required controller pair, termination assemblies, cabling, and system configuration before replacing or adding a controller.

Q: Can the CC-PCNT01 operate with remote non-Series C I/O?

A: Yes. The supplied specifications list PM I/O and Series A I/O as supported remote non-Series C I/O types. Verify the specific I/O configuration and system release before implementation.
