 ==== Introduction ==== ==== Introduction ====
-ModbusTCP is a feature on our [[venus-os:​start|Venus-devices]] eg [[https://​www.victronenergy.com/​panel-systems-remote-monitoring/​colorcontrol|Color Control GX]], and also the [[https://​www.victronenergy.com/​panel-systems-remote-monitoring/​venus-gx|Venus GX]]. ModbusTCP is an industry standard protocol, that can be used to interface PLCs or other equipment with Victron products. For example to enable a heat pump when there is excess solar power, or create a fully integrated glass bridge on a yacht.+ModbusTCP is a feature on our [[venus-os:​start|GX devices]] eg [[https://​www.victronenergy.com/​panel-systems-remote-monitoring/​colorcontrol|Color Control GX]], and also the [[https://​www.victronenergy.com/​panel-systems-remote-monitoring/​venus-gx|Venus GX]].

 +Through the ModbusTCP interface you can read and write date to the chargers, battery monitors, inverter/​chargers and other products connected to the GX device. The unit-id combined with the register address is used as a device-selector:​ selecting for example from which device you want to read its battery voltage measurement.

-(1): Only the Venus GX is provided with temperature sensor inputs. The battery temperature as measured by a sensor connected to a VE.Bus device is not available. And the battery temperature as measured by a sensor connected to a BMV battery monitor is available under the com.victronenergy.battery register set.+(1): Check for compatible [[venus-os:​start|GX devices]] (eg Venus GX) that provide ​temperature sensor inputs. The battery temperature as measured by a sensor connected to a VE.Bus device is not available. And the battery temperature as measured by a sensor connected to a BMV battery monitor is available under the com.victronenergy.battery register set.
  
 General note: not all list registers are available for each device. For example a BMV Battery Monitor has lots of readings: historical data such as maximum/​minimum,​ for example. A canbus-connected lithium battery might not have those parameters available. General note: not all list registers are available for each device.
