INSTCMBG0320000 – BACnet/Modbus to ST Cloud Gateway

INSTCMBG0320000 ST Cloud Control Gateway for BACnet MS/TP, BACnet IP and Modbus.

INSTCMBG0320000 is an Intesis ST Cloud Control gateway designed for remote monitoring and control of devices operating with BACnet and Modbus communication protocols. The device worked as a bidirectional cloud-based solution that connected local building automation devices with a web-based dashboard and an end-user-oriented mobile application. The INSTCMBG0320000 model has been marked by the manufacturer as discontinued with no direct replacement available, so availability and possible alternative communication solutions should be verified before selecting it for a project.

The gateway supports BACnet IP, BACnet MS/TP, Modbus TCP and Modbus RTU, making it suitable for building automation systems, HVAC installations, metering applications and projects based on devices from different manufacturers. On the communication side, the unit uses Ethernet and EIA-485, allowing integration of both network-based devices and serial bus devices. INSTCMBG0320000 is not a classic BACnet-to-Modbus converter, but a gateway that provides remote access to BACnet or Modbus devices through the ST Cloud Control environment.

The ST Cloud Control solution allowed the integration of up to 4 devices, with up to 12 widgets for each device. The system interface was based on automatically generated web dashboards designed for convenient operation by end users. In addition, the system could be controlled through native mobile applications for Android and iOS, making it easier to monitor operating parameters, control devices and supervise installations remotely without using an extensive local BMS or SCADA visualization system.

INSTCMBG0320000 in building automation systems

INSTCMBG0320000 was intended for installations where BACnet or Modbus devices needed to be monitored and controlled remotely from the cloud. The manufacturer’s documentation shows integration examples with devices such as HVAC units, meters, humidifiers, thermostats, VRF units, sensors and commercial units. Depending on the system architecture, the gateway could work with BACnet IP, BACnet MS/TP, Modbus TCP or Modbus RTU devices and then make their data available in the ST Cloud Control environment.

This type of solution was especially useful where a technical user, facility administrator or system integrator needed simple remote access to selected installation parameters without deploying a full local visualization system. The INSTCMBG0320000 variant supports DIN rail mounting and wall mounting, which made it easier to adapt the device to different electrical enclosures, automation cabinets and technical installation points in building automation systems.
