This pull request implements the MODBUS function code FC23 (Read/Write Multiple Registers) as specified in the MODBUS Application Protocol Specification V1.1b3 (Page 38, Section 6.17: "23 (0x17) Read/Write Multiple registers").
The Function Code 23 (Hex 0x17) performs a combination of one read operation and one write operation in a single MODBUS transaction. The write operation is performed before the read.
This implementation was done by Dominik Köhler in the name of Iniationware GmbH, initialized by Klaus Landsdorf - CEO of Iniationware GmbH.
Client and Server now have support for the aforementioned Read/Write Multiple Registers feature. The implemented functionality was tested with unit tests for parsing/serializing an FC23 request/response - and should work as expected. Let me know, if there are any issues when testing.
I've also compiled a basic feature documentation of the FC23 request, accessible under
rodbus\WCFC_README.md, feel free to modify it in any way needed.If you have any open questions, suggestions or notes about the FC23 feature implementation, do not hesitate to let me know. I am always happy to help where I can.
Best regards!
