Modbus is a data communication protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Modbus has become a de facto standard protocol and is now a commonly available means of connecting industrial electronic devices.
This driver provides 2-way communication with Modbus devices to enable control from a Control4 user interface.
- Modbus TCP (communication using TCP/IP)
- Modbus RTU (communication using RS232/RS485)
- Master Driver
- Blind Driver
- Venitian Blind Driver
- Dimmer Driver
- Switched Light Driver
- Relay Driver
- Single Setpoint Thermostat
- Split Setpoint Thermostat
This driver requires that you have the modbus points associated with the device. We will build up a library of devices, but if you don't find the device you need, then you'll need to follow the documentation to create the configuration for you particular device.
This is because even though modbus is a standard protocol, it doesn't specify standards points for devices. So HVAC or lighting devices can use different addresses for the same function.
