通用消息源
目标标签消息缓冲区消息处理器2 DeviceNet DPI 38自动化出版物PFLEXRM002DENE2013年8月第1章详细驱动器配置和操作设置PowerFlex 700S以遵循20COMMD的速度参考，参数691[DPI Ref Select]必须设置为“端口5”。参数16[Speed Ref Sel]必须设置“Speed Ref DPI”。参考和反馈值是PowerFlex 700S中的浮点值。使用以下逻辑以整数数据的形式发送和接收参考和反馈数据。在ControlLogix系统中，数据链路通过DeviceNet作为32位整数（DINT）传输。为了发送或接收浮点，必须使用COP（复制）指令。
复制指令执行
逐位复制。将复制指令的长度设置为适合目标数据类型的值。例如，当将DINT数据类型复制到REAL数据类型时，长度将为一（1），因为两种数据类型都包含32位数据。在ControlLogix系统中使用显式消息时，使用消息类型CIP Generic。数据通过DeviceNet以与PowerFlex 700S中的参数相同的数据类型传输。确保ControlLogix消息指令中源和目标标记的数据类型与PowerFlex 700S中的数据类型匹配。此外，ControlLogix消息指令中的元素数必须与源数据的大小匹配。例如，要发送一条显式消息以写入参数12[Speed Ref 2]，该参数为浮点：•Source和Destination标记应为REAL类型。•元素数应为4字节，因为REAL数据类型占用4字节的数据。
Common Message Source
Target tag message buffer message processor 2 DeviceNet DPI 38 automation publication PFLEXRM002DENE August 2013 Chapter 1 Detailed drive configuration and operation settings PowerFlex 700S to follow the speed reference of 20COMMD, parameter 691 [DPI Ref Select] must be set to "Port 5". Parameter 16 [Speed Ref Sel] must set "Speed Ref DPI". Reference and feedback values are floating point values in PowerFlex 700S. Use the following logic to send and receive reference and feedback data in the form of integer data. In the ControlLogix system, the data link is transmitted as a 32-bit integer (DINT) through DeviceNet. In order to send or receive floating-point, the COP (copy) instruction must be used.
Copy instruction execution
Copy bit by bit. Set the length of the copy instruction to a value appropriate for the target data type. For example, when you copy the DINT data type to the REAL data type, the length will be one (1) because both data types contain 32-bit data. When using explicit messages in a ControlLogix system, use the message type CIP Generic. Data is transmitted through DeviceNet in the same data type as the parameters in PowerFlex 700S. Ensure that the data types of the source and target tags in the ControlLogix message instructions match the data types in the PowerFlex 700S. In addition, the number of elements in the ControlLogix message instruction must match the size of the source data. For example, to send an explicit message to write parameter 12 [Speed Ref 2], which is a floating point: • Source and Destination tags should be REAL. • The number of elements should be 4 bytes, because the REAL data type takes up 4 bytes of data.
