集成网关intesisbox把Modbus 从设备转成KNX控制系统，集成到Modbus RTU从站设备（冷水机组，楼宇，电表，暖气地板，热泵，PLC）到KNX控制系统转换
IntesisBox acts as a Modbus RTU master device in its Modbus interface, reading/writing points of the Modbus slave device(s), and offering this point"s values through its KNX interface. IntesisBox acts in the KNX side as one more device of the KNX system. IntesisBox"s KNX EIB interface connects directly to the EIB bus and is opto-isolated from the rest of the internal electronics
The Modbus interface of IntesisBox reads continuously by polling the Modbus slave devices/registers configured. If a non response of the Modbus slave is detected, the corresponding virtual signal inside IntesisBox will be activated indicating communication error with the device. All the updated readings of the Modbus registers are maintained in IntesisBox memory for immediate interaction with KNX when needed.
Each Modbus register of the slave device is associated to a KNX group address. All the Modbus registers of the different slaves are accessible through KNX group addresses.
When a change in any Modbus register/slave occurs, a write telegram is sent to the KNX bus, to the associated KNX group address. This is configurable individually per point.
IntesisBox KNX series are configured using
| Modbus 设备类型 | ||||
| 点数 | 100 | 500 | 3000 | 能定义最大的点数到Intesisbox中 |
| Modbus从站设备 | 254 | 254 | 254 | 最大的从站设备点数也可以定义到Intesisbox中 |
