The Foxboro P0916MZ I/A Series Baseplate-to-Baseplate Cable is a dedicated communication cable used to connect compatible baseplates within Foxboro I/A Series distributed control systems. It carries a 2 Mbps communication link between baseplates, supporting data exchange between interconnected sections of a control system.
In modular DCS installations, baseplates provide the physical mounting and electrical interconnection for processors, fieldbus modules, and other control hardware. When a system uses multiple baseplates, the appropriate interconnection cable is required to establish the intended communication path. The P0916MZ serves this purpose in compatible I/A Series configurations.
This cable is associated with the I/A Series modular baseplate architecture, including installations that use compatible control processors and I/O baseplates. Its application is different from that of a field termination cable, which connects an I/O module to a termination assembly. The P0916MZ is intended for baseplate-to-baseplate communication rather than direct field-signal wiring.
During system design or maintenance, engineers should confirm the required communication interface, baseplate configuration, connector arrangement, and cable routing. Correct cable selection is particularly important when expanding an existing control system or replacing an interconnection cable during a planned shutdown.

The P0916MZ establishes a communication connection between compatible Foxboro I/A Series baseplates. In a modular control system, interconnected baseplates allow supported control hardware to participate in the intended system communication architecture.
The cable forms the physical link between the relevant baseplate interfaces. Once the cable is correctly connected and the system hardware is configured, communication can take place through the supported baseplate communication path. The cable itself does not execute control logic, process field inputs, or generate output commands; those functions remain with the connected processors and I/O modules.
A typical installation may include a control processor mounted on one baseplate and additional compatible control hardware on another. The interconnection cable supports communication between the baseplates according to the system design. The actual communication path and supported hardware arrangement depend on the installed I/A Series architecture.
Cable compatibility is essential. A cable intended for baseplate-to-baseplate communication should not be treated as interchangeable with a fieldbus termination cable or an I/O termination assembly cable simply because the connectors or cable lengths appear similar. These components serve different electrical and communication functions.
During troubleshooting, intermittent or absent communication can result from a loose connector, damaged cable, incorrect connection, or a fault elsewhere in the communication path. Engineers should inspect the physical connection and review the system’s diagnostic information before replacing control modules. A cable replacement should also preserve the intended baseplate arrangement and communication configuration.
The P0916MZ provides the physical communication link between compatible baseplates within an I/A Series control system. It supports the modular architecture by connecting control hardware installed on separate baseplates.
Control Processor / System Hardware → Baseplate Communication Interface → P0916MZ Cable → Compatible Baseplate Interface → Connected Control Hardware
| System Component | Function |
|---|---|
| P0916MZ Cable | Establishes the baseplate-to-baseplate communication connection |
| I/A Series Baseplate | Provides mounting and interconnection for compatible control hardware |
| Control Processor | Executes configured control logic and manages supported system operations |
| Fieldbus Modules | Interface with supported field devices and process signals |
| Additional Baseplate | Accommodates compatible hardware within the modular control architecture |
| System Communication Infrastructure | Supports data exchange between interconnected control-system components |
| Engineering and Diagnostic Tools | Assist with configuration checks and communication troubleshooting |
The exact role of each connected baseplate depends on the installed system configuration. The P0916MZ supplies the cable connection; it does not replace the processor, baseplate, or other hardware required to establish a functioning control system.
| Application | Typical Use |
|---|---|
| Distributed Control Systems | Connecting compatible baseplates in modular I/A Series installations |
| Process Automation | Supporting the interconnection of control hardware in process-control cabinets |
| Power Generation | Maintaining baseplate communication in compatible plant control systems |
| Chemical Processing | Connecting modular control hardware used for process monitoring and control |
| Oil and Gas Facilities | Supporting existing I/A Series control-system infrastructure |
| Industrial Control Cabinets | Establishing communication links between compatible baseplate assemblies |
| System Expansion | Connecting additional baseplates where the architecture supports this arrangement |
| Control-System Maintenance | Replacing a faulty or damaged baseplate communication cable |
| Plant Modernization | Maintaining existing interconnections during compatible hardware replacement projects |
Application suitability depends on the installed Foxboro system architecture, baseplate interfaces, and required communication path. The cable should be selected according to the actual hardware configuration rather than its model designation alone.
If communication remains unavailable after cable replacement, verify the baseplate interfaces, connector seating, system configuration, and status of the connected hardware. Avoid assuming that the cable is the sole cause of a communication fault.
The P0916MZ is associated with compatible Foxboro I/A Series baseplate communication arrangements. Related hardware must be selected according to the installed system architecture and the role of each component.

The P0916MZ connects compatible Foxboro I/A Series baseplates through a 2 Mbps communication link. It supports communication between interconnected control-system hardware rather than connecting an I/O module directly to a field termination assembly.
No, not simply on the basis of cable length or physical appearance. A baseplate-to-baseplate cable and an FBM termination cable serve different functions and connect to different parts of the system architecture. Confirm the required connection type before selecting a replacement.
Inspect both connectors, confirm the correct baseplate interfaces, and check the system’s communication diagnostics. If the cable connection is correct, investigate the connected baseplates, installed hardware, and configuration before concluding that the cable is defective.
Confirm that RH916MZ is approved for the specific installed baseplate configuration and required communication function. Also verify the connector arrangement and any applicable system-specific requirements before installing the replacement.
