Cross-Protocol Data Exchange with the PLX31-EIP-MBTCP
The PLX31-EIP-MBTCP connects EtherNet/IP controllers to Modbus TCP servers across plant networks. This gateway exchanges register data between Rockwell systems and Modbus field devices. System integrators therefore apply it where mixed-protocol architectures demand direct data flow. Its DIN-rail housing mounts inside standard enclosures without extra brackets.
Detailed Technical Parameters
Protocol mapping defines the PLX31-EIP-MBTCP, because the processor board translates data tags between EtherNet/IP and Modbus TCP frames. Dual Ethernet ports support daisy-chain wiring across cabinet layouts. Meanwhile, the gateway handles client and server roles on both protocol sides. Review the essential specifications in the table below.

Integration into Control Systems
The PLX31-EIP-MBTCP snaps onto a DIN rail and connects through standard Ethernet cables. Commissioning engineers configure tag mapping through the setup software. Consequently, cross-protocol links return to service quickly after gateway replacement. The device converts protocol frames within milliseconds of each scan cycle. Furthermore, the metal housing resists interference from drives and power equipment nearby.
Why Plants Choose This Gateway
Many facilities still operate mixed-protocol environments for their proven process reliability. Hence, the PLX31-EIP-MBTCP serves as a dependable spare for keeping data links online. Its standardized DIN-rail format simplifies stock management across multiple sites. In addition, the dual-port design reduces cabling requirements inside cabinets. This gateway keeps production data flowing and schedules on track.
