Product Overview
The DSCS140 is a high‑performance communication processor module designed for industrial automation networks. It serves as a central communications node for the MasterBus 300 (MB300) architecture, enabling seamless data exchange between controllers, I/O stations, field devices, HMIs and SCADA systems. With its robust hardware, it supports demanding environments, long‑term reliability and flexible network topology integration.
The module is intended for use in process plants, manufacturing automation, utilities and similar industrial environments where reliable, high‑speed communication and system integration are critical. Its compact design allows installation within control racks or network cabinets, and the module supports plug‑in or rack‑mounted formats for ease of maintenance and replacement.

Product Description
The DSCS140 acts as the “brain” of the communication layer in an industrial automation system using the MB300 bus architecture. It interfaces between field‑level I/O modules, subsystems and the higher‑level control network, handling message routing, protocol bridging and ensuring data integrity. The module helps to unify network communications, enabling efficient exchange of sensor and actuator status, control commands and diagnostics.
Architecturally, the module is designed to fit into a control rack in the automation cabinet. With its compact form factor and modular design, it allows rapid servicing and replacement when required. The DSCS140 is built to operate continuously under industrial conditions: temperature extremes, vibration, electromagnetic interference and network load. Its role is critical for system uptime and network performance — a fault in the communications processor can degrade or disable entire subsystems.
Product Applications
-
Process automation plants (chemical, petrochemical, oil & gas) where multiple I/O modules and controllers must communicate reliably.
-
Manufacturing automation systems with stringent network requirements, such as automotive, heavy machinery and plant control.
-
Utilities (water/wastewater, power distribution) where control systems rely on robust communications between sensors, actuators and control stations.
-
Networked building automation systems, transportation systems or infrastructure‑automation where data integration and reliability are vital.
-
Retrofitting or upgrading legacy I/O rack systems (MasterBus 300 architectures) where a communication processor is needed to link existing I/O and controllers.
