关闭Modbus/TCP客户端连接(3001)应用程序通过发出关闭Modbus-TCP客户端连接COMMREQ来关闭Modbus+TCP客户端连接。Close COMMREQ关闭底层TCP连接,并为其他通信任务释放通道。如果COMMREQ中的信道号标识非Modbus/TCP客户端连接或非活动信道,则返回错误响应。10.4.2.1命令3001示例终止在通道5上建立的Modbus/TCP客户端连接。将COMMREQ状态字返回%R10。(字7)通道命令号:字7请求关闭通道服务。(字8)通道命令号:字8标识先前通过Open Modbus/TCP Client Connection请求打开的通道。如果关闭Modbus/TCP客户端连接被发送到已关闭的通道,则返回成功的CRS值1。从Modbus/TTCP设备读取数据(3003)从Modbus-TCP设备读取数据COMMREQ请求从Modbus+TCP设备向PLC传输数据。读取数据COMMREQ必须参考先前通过Open Modbus/TCP Client Connection COMMREQ建立的活动Modbus/TTCP通道。
Close a Modbus/TCP Client Connection (3001) The application program closes a Modbus/TCP Client Connection by issuing the Close Modbus/TCP Client Connection COMMREQ. The Close COMMREQ closes the underlying TCP connection and frees the channel for other communication tasks. An error response is returned if the channel number in the COMMREQ identifies a non-Modbus/TCP Client connection or an inactive channel. 10.4.2.1 Command 3001 Example Terminate the Modbus/TCP Client connection established on Channel 5. Return the COMMREQ Status word to %R10.(Word 7) Channel Command Number: Word 7 requests the Close channel service. (Word 8) Channel Command Number: Word 8 identifies a channel previously opened with an Open Modbus/TCP Client Connection request. If a Close Modbus/TCP Client Connection is sent to a channel that is already closed, a success CRS value of 1 will be returned.Read Data from a Modbus/TCP Device (3003) The Read Data from a Modbus/TCP Device COMMREQ requests a data transfer from a Modbus/TCP device to the PLC. The Read Data COMMREQ must reference an active Modbus/TCP channel previously established with the Open Modbus/TCP Client Connection COMMREQ.
