PQM允许在一次传输中存储60个寄存器。PQM对该功能代码的响应是响应从属地址、功能代码、起始地址、存储的设置点数量和CRC。消息格式和示例：请求从设备17将值01F4存储到设定点地址1028，将值2710存储到设定值地址1029。本示例中的传输完成后，PQM从机17将存储以下设置点信息：功能代码16-执行命令某些PLC可能不支持使用功能代码5执行命令，但支持使用功能码16存储多个设置点。要使用功能代码16（10H）执行此操作，必须同时向PQM写入特定的命令序列。序列包括：命令功能寄存器、命令操作寄存器和命令数据（如果需要）。命令功能寄存器必须写入值5，表示请求执行操作。然后，必须使用内存映射中显示的命令列表中的有效命令操作编号写入命令操作寄存器。
The PQM allows 60 registers to be stored in one transmission. The PQM response to this function code is to echo the slave address, function code, starting address, the number of Setpoints stored, and the CRC. MESSAGE FORMAT AND EXAMPLE: Request slave 17 to store the value 01F4 to Setpoint address 1028 and the value 2710 to setpoint address 1029. After the transmission in this example is complete, PQM slave 17 will have the following Setpoints information stored: Function Code 16 - Performing Commands Some PLCs may not support execution of commands using function code 5 but do support storing multiple setpoints using function code 16. To perform this operation using function code 16 (10H), a certain sequence of commands must be written at the same time to the PQM. The sequence consists of: Command Function register, Command operation register and Command Data (if required). The Command Function register must be written with the value of 5 indicating an execute operation is requested. The Command Operation register must then be written with a valid command operation number from the list of commands shown in the memory map.
