Communication Module 41
Chapter 3 System Description
Communication Module
The following communication components are available.
The Communication Module (CM) is an optional, three-to-one interface to the
MPs. Using a variety of communication methods, protocols, and physical media
types, the CM enables communication with:
• External host computers
• Distributed control systems (DCS)
• Open networks
• Network printers
• Other Trident systems
• Tricon V9 systems
A single Trident controller supports up to two CMs on one CM Baseplate. Each
CM operates independently and supports three RS-232/485 serial ports and two
Ethernet ports. Two CMs can provide redundant communication connections or
additional independent communication ports.
The CM Baseplate should be connected directly above or below an MP Baseplate.
Two MP Interconnect Assemblies are required to connect the MP Baseplate to the
CM Baseplate. For more detailed information, see the Trident Communication
Guide.
Communication Capabilities
Each CM provides the following communication capabilities:
• Serial ports
• Network ports
• Protocol support
