Modbus 0x17 refers to a specific function code in the Modbus protocol. The Modbus protocol is a communication protocol commonly used in industrial automation systems to establish communication between devices such as programmable logic controllers (PLCs) and other electronic devices.
Function code 0x17, also known as "Read/Write Multiple Registers," allows the reading and writing of multiple registers in a Modbus device. This function code is used to request data from multiple registers or write data to multiple registers in a single Modbus transaction.
To use function code 0x17, you need to specify the starting address of the registers you want to read or write, as well as the number of registers to include. The response from the device will contain the requested data or acknowledge the successful write operation.
It's important to note that the specific implementation of Modbus and its function codes can vary depending on the device and the Modbus protocol variant being used (such as Modbus RTU, Modbus TCP, etc.).
