Modbus Register List

The Modbus register is supported both on function call 2 and function call 4. The data is stored as either:

  • UINT32 (unsigned 32–bit integer), most significant word in n+0, least significant word in n+1, also known as big-endian.

  • UINT16 (unsigned 16–bit integer), registers are transmitted as with the most significant bit (MSB) first, also known as big-endian.

  • ASCII (the printable ASCII subset from 0x20 – 0x7E), strings with unused characters (length less than maximum) are filled with nulls. Strings are two characters per register, first character in high-order byte, second character in low-order byte.

  • Boolean (a single bit, 0 or 1), 1 = alarm active, reserved or undefined registers will return an error. Blocked reads which begin with a valid register will not return an error but will return zeros for undefined registers.

  • FP (floating point)

All registers are read only (RO). Bit 0 is the least significant bit.

NOTE: For the Modbus register the absolute starting register address is 0, this is equivalent to 40001 in Modicon terminology (address zero when transmitted over the wire).
