INBACMBM6000000 – Modbus RTU/TCP to BACnet IP/MSTP Gateway 600 Points

INBACMBM6000000 – Modbus RTU/TCP to BACnet IP/MSTP Gateway 600 Points. 

The INBACMBM6000000 gateway from Intesis (HMS Networks) enables transparent, bidirectional integration of Modbus RTU and Modbus TCP slave devices into BACnet ecosystems supporting BACnet IP and BACnet MS/TP. With capacity for up to 600 data points, it bridges legacy Modbus hardware—energy meters, HVAC controllers, PLCs, sensors—into a modern BACnet BMS or SCADA without additional converters.

Certified by BTL to the B-AAC (Advanced Application Controller) profile, the device guarantees seamless interoperability with professional BACnet controllers. Simultaneous RTU and TCP operation simplifies hybrid projects: serial field buses on RS-485 coexist with Ethernet-based Modbus devices, all exposed as standard BACnet objects.

Compact and robust, the unit features two isolated serial interfaces (Port A RS-485, Port B RS-485/RS-232) plus a 10/100 Mbps Ethernet port. DIP-switches allow quick activation of 120 Ω termination and line polarisation. 1500 V DC galvanic isolation between ports protects against ground loops and industrial noise, ensuring reliable communication even in harsh electrical environments.

Installation is flexible: a wide 9–36 V DC or 24 V AC power range, DIN-rail or wall mounting, and flame-retardant UL 94 V-0 polycarbonate housing (IP20). On-board LEDs provide instant diagnostics for power, errors, Ethernet link/speed, and TX/RX activity on each serial port, speeding up commissioning and maintenance.
