Sources and notes

  • Modbus Register Mapping, Control · version A029X159 (Issue 26), 2020-06
    sections 12, table 27 (registers marked PS0500), and 14 (fault status bitmaps marked PS0500)

  • Addresses are the manual's 4xxxx numbers less 40000, 1-based (40011 is holding register 11).
  • 32-bit values have the high register first. Write both registers, high then low.
  • Text values the manual lists as one character per register (serial numbers, time stamps) are left out.
  • The manual does not give the factory serial settings: check baud rate, parity, stop bits and node address on the control.
  • Save Trims writes the settings to flash memory, which wears out: use it only after a change, never on a schedule.
  • Registers missing from older control software answer with an exception.
  • Modbus works only from PS0500 software version 6.02.
  • Some fault bitmap bits mean one fault on the PS0500 and another on PowerCommand 2.x/3.x; these are the PS0500 ones.
  • 32 one-character text registers left out.
