Modbus RTU

ModbusRTU是开放式主/从协议可方便用干串口设备上众多自动化系统把Modbus RTU接口作为标准或可选设备，因此可很容易通过集成于AC500上的COM1和COM2口(RS232或RS485)与之通讯。Modbus不但用于工业场合，而且用于建筑安装，能源优化系统，远距离数据传输和连接操作面板等。

1, the bottom plate can be installed and plugged into a full series of CPU modules

2. 1 to 4 slots can be used to connect the local I/0 expansion of different communication modules, and up to 10 1/0 module baseboards can be connected

3, integrated an FBP interface that can be used for slave station communication

4, integrated COM1 port (pluggable terminal) and integrated COM2 port (SUB-D plug)

Modbus RTU

ModbusRTU is an open master/slave protocol for ease of use Many automation systems on dry serial devices have the ModbusRTU interface as standard or optional, so it can be easily communicated via COM1 and COM2 ports (RS232 or RS485) integrated on the AC500. Modbus is not only used in industrial applications, but also in building installations, energy optimization systems, long-distance data transmission and connecting operation panels.
