产品详细资料
打开Modbus/TCP客户端连接(3000)Modbus/TTCP以太网接口使用通道将数据传输到另一个Modbus/TPC设备或从另一个Modbus设备传输数据。多达32个通道可用于Modbus/TCP客户端通信。然而,这32个信道与SRTP信道共享,因此SRTP信道和Modbus/TCP信道的组合不能超过32个。Open Modbus/TCP COMMREQ请求通信子系统将信道与远程Modbus/TTCP设备相关联。使用本文件后面定义的COMMREQ,PLC可以将数据传输到远程设备或从远程设备传输数据。一旦为Modbus/TCP客户端通信分配了信道,该信道将保持分配状态(即SRTP信道等其他协议无法使用该信道)。PACSystems™ RX3i和RSTi EP TCP/IP以太网通信用户手册0节GFK-2224Y 2019年8月Modbus/TCP Client 187信道连接仅在以下情况下释放:应用程序关闭信道,当PLC转换为STOP时,当以太网接口使用冗余IP,CPU从活动单元转换为备份单元时,信道自动关闭,以太网接口被重置或者底层TCP连接被终止。
Open a Modbus/TCP Client Connection (3000) The Modbus/TCP Ethernet interface transfers data to or from another Modbus/TCP device using a channel. Up to 32 channels are available for Modbus/TCP client communications. However, these 32 channels are shared with SRTP Channels so that the combination of SRTP Channels and Modbus/TCP Channels cannot exceed 32. The Open Modbus/TCP COMMREQ requests the communication subsystem to associate a channel with a remote Modbus/TCP device. Using the COMMREQs defined later in this document the PLC may transfer data to and from a remote device. Once a channel is allocated for Modbus/TCP Client communications, the channel remains allocated (i.e. another protocol such as SRTP Channels cannot use the channel).The PACSystems™ RX3i and RSTi-EP TCP/IP Ethernet Communications User Manual Section 10 GFK-2224Y August 2019 Modbus/TCP Client 187 channel connection is released only when: the application program closes the channel, the channel is automatically closed when the PLC transitions to STOP, when the Ethernet interface uses a Redundant IP and the CPU transitions from the Active to the Backup unit, the Ethernet interface is reset or the underlying TCP connection is terminated.
