Protocols and Gateways

The Modius OpenData solution is able to unify information by collecting data using any standard communication protocol at the physical layer, including:

  • Modbus
  • BACnet
  • SNMP
  • Proprietary protocols
  • RESTful API

Because Modius OpenData works across all major device protocols, the solution is uniquely able to capture data from all major device categories and equipment vendors. For equipment that is not accessible on the network (via network communication cards), Modius provides a serial-to-network gateway to ensure that all of your critical equipment can be monitored. Modius OpenData can also capture data from existing systems, such as a BMS, which allows operators to leverage the legacy systems that they already have in place.

The Modius Standard RTU is a versatile and powerful system used for monitoring and control of equipment sites.

This is a high powered full function Remote Telemetry Unit (RTU). The Modius Standard RTU has built-in physical interfaces for connecting to contact closure I/O’s, analog sensors, and serial ports, making it ideal for monitoring and controlling a multitude of devices all from one box.
