Hello everyone

My project is communication between X-RAY machine and PLC. I use CP 341 for communication of MODBUS RTU then the X-RAY has address 40100 - 40104 and address 40150 - 40157 . How can I setup data block buffer.

You don't need to reserve space for all those registers, you need only a couple of dozen words: for the header and the user data.

Which Modbus driver library do you use?
