Sources and notes

Source: AEPH do Brasil Egeo manual, chapters 15-17 (Modbus RTU protocol); AEPH do Brasil MATRIX manual, chapter 22 (Modbus RTU protocol); AEPH do Brasil ORION manual, chapter 19 (Modbus RTU protocol)

  • Modbus RTU (slave); set PR = rtU on the indicator. FC03 reads and FC06 writes holding registers. Addresses are 0-based, as sent on the wire.
  • The manual allows 9600 to 115200 bit/s, 8 data bits, no parity and 1 or 2 stop bits (set in the serial menu). It gives no default: 9600 and 1 stop bit are placeholders. The address (END) is 1 to 99.
  • Weight and tare are 17-bit values split over two registers: the high byte of the first register holds the status (or the decimal places), its lowest bit is bit 16 of the value, and the second register holds bits 0-15. They are given here as separate registers because the format has no type for this layout.
  • Only the weight, tare and remote command registers are mapped. The register table also lists setpoint, calibration, analog output, clock and other configuration registers (0x0003 to 0x006F) whose value encoding the manual does not describe, so they are left out.
  • The register table shows the weight and tare at 0x000A-0x000B and 0x000C-0x000D, as the example frames do.
  • The command values follow the manual's example frames (1 = tare, 2 = zero, 3 = clear tare, 4 = print); the text next to the frames disagrees in places.
  • Written from the manual; this map has not been tested on a device.
  • The manual asks for 19200 bit/s, 8 data bits, no parity, 2 stop bits. The address (END) is 1 to 99.
  • The manual's register list gives the weight and tare registers as 0x0010 and 0x0012, but its example frames read them at 10 (0x000A) and 12 (0x000C); this map follows the frames.
