We are designing RS485 devices to be daisy chain wired to a AXL F RS UNI 1H, with 3152 CPU. Looking for guidance on how to program Modbus communication to Read/Write Register values. The UM/APP documents are extremely detailed (bit level)/confusing. Any guidance is much appreciated.
Hello,
the Modbus RTU library can be downloaded from the PLCnext Store: PLCnext Store | Modbus_RTU. It contains not only the library but also code examples of how to use Modbus RTU with the AXC F RS Uni module. If this does not help, please leave a comment here.
