  • The manual gives the addresses without saying whether they are 0- or 1-based. The one example it gives (holding register 0x07D0 is decimal 2000) is a wire address, so they are given here as 0-based. If a read fails, try address_base 1.
  • Defaults from the manual: 19200 baud, 8 data bits, even parity, 1 stop bit, slave address 247. When the address is changed it can be 1 to 246.
  • Byte order is ABCD for floats and 32-bit integers (big-endian words). Each float takes two registers.
  • The manual lists the 4.6.3 table as Read Input Registers (0x04) and the 4.6.6 table as Write Multiple Holding Registers (0x10). The holding registers are given as RW; the manual does not say they can be read back with 0x03.
  • Input and holding registers use the same numbers for different things (3222, 3400 to 3406): they are separate address spaces.
  • Error flags: register 3200 holds all flags as a bit field (the manual numbers the bits 1 to 16, here 0 to 15). Registers 3201 to 3216 repeat each flag as a register; the manual lists no Error9 flag.
  • In the manual's unit lists for registers 3400 and 3701, value 4 is printed as l/h, the same as value 2. It is most likely l/s.
  • Changing the interface parameters is a three step write: 0xAC1D to register 5010, the parameter word to register 2000, then 0xBA5E to register 5020; restart the device afterwards.
  • The device also answers Read Device Identification (0x2B / 0x0E) with the vendor, product code, software version and serial number as text; this is not a register, so it is not in the map.
  • Written from the manufacturer's document; not tested on a device.
