In general use, you have to polling Coil 1016. When it change to 1 it is mean that the
RFID device read new tag. Holding registers 1002-1011 contains tag ID.
When you read ID number you should release Coil 1016 (or Holding Reg 1000) flag
(clear to 0). Only after that the reader is able to read next ID tag.
Modification of the output parameters can be done by the Modbus protocol. It is not
stored in the module's permanent memory. That means after reboot, the output
parameters previously saved to the EEPROM by the configuration program will be
restored.
