- Pulp & Paper / Water Treatment: Legacy PLC and RTU serial bridge to DeltaV control network
Engineering Advantages
- Native DeltaV platform compatibility — no additional gateway hardware required
- Supports both RS-232 (point-to-point) and RS-485 (multi-drop, up to 32 nodes) topologies
- Hot-swap capable within DeltaV I/O subsystem for minimal process disruption
- Deterministic serial communication with configurable baud rates and parity settings
- Compact card form factor reduces panel space requirements
- Full backward compatibility with existing DeltaV I/O carrier and controller infrastructure
System Architecture & Signal Flow
The KJ3241X1-BA2 installs directly into a DeltaV I/O carrier card slot. Serial field devices connect via the card’s RS-232 or RS-485 port. Data is transmitted over the DeltaV I/O bus to the DeltaV controller, where it is processed and made available to the DeltaV Operate HMI and historian. The module supports standard Modbus RTU and proprietary serial protocols as configured in DeltaV Control Studio. Signal isolation and surge protection are provided per Emerson’s I/O subsystem design standards.
