INSTCMBG0320000 – BACnet IP/MS/TP or Modbus TCP/RTU to ST Cloud Gateway for 32 Devices

INSTCMBG0320000 – BACnet IP/MS/TP or Modbus TCP/RTU to ST Cloud Gateway for 32 Devices. 

The INSTCMBG0320000 is a robust, industrial-grade gateway that enables full cloud connectivity for BACnet IP, BACnet MS/TP, Modbus RTU and Modbus TCP devices. Designed specifically for integration with the ST Cloud Control platform, this device allows seamless remote monitoring and control of up to 32 individual devices through intuitive app and web interfaces.

The gateway can operate in three different modes: as a BACnet IP Client, a BACnet MS/TP Master, or as a Modbus RTU Master and Modbus TCP Client. Its BTL certification ensures full compatibility with any BACnet device, guaranteeing a reliable and smooth integration within any BMS or industrial control environment.

On the Modbus side, the gateway supports up to 5 Modbus TCP nodes, and offers broad protocol flexibility with support for multiple function codes (1x, 2x, 3x, 4x, 5x, 6x, 15x, 16x). Additionally, data format customization options include bit lengths of 1, 16, 32, 48, or 64 bits, and data types such as unsigned, signed, floating point, or bitfield. The device also allows selection of byte order between big endian and little endian.

Configuration is performed via the Intesis MAPS software, which offers a powerful, user-friendly interface for defining communication parameters, testing configurations, and importing preconfigured templates. Once installed, configured, and linked to a registered ST Cloud Control user, all data points and widgets associated with the connected devices become visible within the ST app and browser interfaces for real-time control and visualization.
