  "Addresses are relative to the module: the Modbus address on the 4510 is the slot's base address (set on the Modbus page of the 4510 web console: reload the default addresses or edit them) plus the relative address given here, separately for coils, discrete inputs, holding registers and input registers. Modbus/TCP port 502 on the ioThinx 4510 adapter.",
  "The manual lists every parameter with a length: in bits for coils and discrete inputs, and in 16-bit registers for the others. A DWORD or REAL value takes two registers; a REAL is a 32-bit float. Per-channel entries here follow that: for example 8 registers of DWORD for 4 channels are four 32-bit values.",
  "The manual does not state the word order of the 32-bit values; big is assumed. The function codes are 1, 5 and 15 for coils, 2 for discrete inputs, 3, 6 and 16 for holding registers and 4 for input registers.",
  "Each 'All' register is a bit mask with one bit per channel."
