Mitsubishi MELSEC iQ-R Ethernet/IP Module RJ71EIP91

Mitsubishi MELSEC iQ-R RJ71EIP91 Ethernet/IP Module — Seamless Rockwell/SCADA Integration for Saudi Plants

The Mitsubishi MELSEC iQ-R RJ71EIP91 is a 100BASE-TX Ethernet/IP adapter module that enables iQ-R PLCs to communicate as slave devices on EtherNet/IP networks. In Saudi Arabia — where Rockwell Allen-Bradley PLCs (ControlLogix, CompactLogix) dominate many Aramco and SABIC facilities, and where Emerson DeltaV and Siemens PCS 7 DCS systems use EtherNet/IP as a primary plant floor network — the RJ71EIP91 allows Mitsubishi iQ-R to integrate as a smart device without a separate gateway.

The module supports Class 1 (cyclic) and Class 3 (message) communication, with up to 512 bytes input + 512 bytes output assembly data. Explicit messaging (CIP) allows reading/writing specific tags — enabling deep integration with Rockwell FTView SCADA and FactoryTalk HMI systems found across Saudi industrial facilities.
