SPC Bridge Modbus

SPC Bridge Modbus allows integration of Vanderbilt SPC intrusion system with a third-party system, e.g. a SCADA system, using the Modbus protocol. Using the SPC Bridge you are able to use events from all your SPC connected motion detectors, door/window contacts, fire detectors and alarm status for automations in the third-party system.

Secure and reliable

All communication between the SPC panel and the Bridge is encrypted and occurs on your local network. No cloud service is involved. Vanderbilt's official protocol FlexC is used. The SPC panel settings determine what can be controlled and monitored.

Modbus TCP server

The SPC Bridge provides a Modbus TCP server to which Modbus clients, such as Siemens LOGO! or a SCADA system, can connect.
Following states, status and commands from/to the SPC system are mapped to predefined Modbus registers:

  • SPC area command objects
  • SPC area status objects
  • SPC zone command objects
  • SPC zone state and status objects
  • SPC output command objects
  • SPC output state objects
  • SPC door commands objects
  • SPC door status objects
The map is designed for an absolute maximum of 16 areas, 256 zones, 16 outputs and 8 doors.
