产品详细资料
COMMREQ状态字地址偏移:此字包含所选存储器类型内的偏移。状态字地址偏移量是一个从零开始的数字。例如,如果您希望%R1作为CRS字的位置,则必须为偏移量指定一个零。%R100的偏移量为十进制99。请注意,这是通道命令中基于零的字段。(单词5):保留。设置为零。(单词6):保留。设置为零。(字7及以上)数据块:数据块定义要执行的信道命令。有关如何填写通道命令信息的信息,请参阅下一节。Modbus/TCP通道命令本节介绍通道命令的操作。其中包括每个通道命令的详细描述和示例。有四个通道命令:▪ 打开Modbus/TCP连接▪ 关闭Modbus/TCP连接▪ 从Modbus服务器设备向PLC读取数据▪ 将数据从PLC写入Modbus服务器设备▪ Modbus服务器设备的掩码写入寄存器请求▪ 在PLC存储器和Modbus服务器设备之间读取/写入多个寄存器请注意,Modbus/TCP通道COMMREQ(与SRTP通道COMMREQs不同)不包含配置超时值的参数。强制Modbus通道命令超时由用户自行决定,必须在用户应用程序中执行。
COMMREQ Status Word Address Offset: This word contains the offset within the memory type selected. The status word address offset is a zero-based number. For example, if you want %R1 as the location of the CRS word, you must specify a zero for the offset. The offset for %R100 would be 99 decimal. Note that this is the only zerobased field in the Channel commands. (Word 5): Reserved. Set to zero. (Word 6): Reserved. Set to zero. (Words 7 and up) Data Block: The Data Block defines the Channel command to be performed. For information on how to fill in the Channel command information, see the next section.Modbus/TCP Channel Commands This section describes the operation of the Channel commands. A detailed description and example of each Channel command is included. There are four Channel commands: ▪ Open a Modbus/TCP Connection ▪ Close a Modbus/TCP Connection ▪ Read Data from a Modbus Server Device to the PLC ▪ Write Data from the PLC to a Modbus Server Device ▪ Mask Write Register Request to a Modbus Server Device ▪ Read/Write Multiple Registers between PLC memory and a Modbus Server Device Please note that Modbus/TCP channel COMMREQs (unlike SRTP channel COMMREQs) do not contain a parameter to configure a timeout value. Enforcing a timeout for a Modbus channel command is at the discretion of the user and must be implemented in the user application.
