PF2100 MODBUS REGISTER MAP | PROFIRE ENERGY INC.
READ-ONLY INPUT/HOLDING REGISTERS
The Input Registers (300xx) are 2-byte read-only values. They are mirrored in corresponding Holding Registers (400xx) for convenience and to
maintain compatibility with some PLCs.
Use the “Read Input Registers” Command (0x04) to read the Input Registers (300xx).
Use the “Read Holding Registers” Command (0x03) to read the Holding Registers (400xx).
Example 1: Read Single
Reading 1 register starting from Register Offset 3 will result in two data bytes being returned.
The first byte will be the most significant byte of Register Offset 3, and the second byte will
be the least significant byte.
Example 2: Read Multiple
Reading 2 registers starting from Register Offset 3 will result in two data bytes being returned. The first byte will be the most significant byte
of Register Offset 3 and the second byte will be the least significant byte. The next two bytes will contain the value of Register Offset 4.
