40025 Setpoint Output Register (SOR) 0 15 N/A Read/Write
Status of Setpoint Outputs. Bit State: 0 = Off, 1 = On.
Bit 3 = S1, Bit 2 = S2, Bit 1 = S3, Bit 0 = S4.
Outputs can only be activated/reset with this register
when the respective bits in the Manual Mode Register
(MMR) are set.
40026 Manual Mode Register (MMR) 0 31 0 Read/Write
Bit State: 0 = Auto Mode, 1 = Manual Mode
Bit 4 = S1, Bit 3 = S2, Bit 2 = S3, Bit 1 = S4,
Bit 0 = Linear Output
40027 Reset Output Register 0 15 0 Read/Write
Bit State: 1 = Reset Output, bit is returned to zero
following reset processing; Bit 3 = S1, Bit 2 = S2,
Bit 1 = S3, Bit 0 = S4
40028 Analog Output Register (AOR) 0 4095 0 Read/Write
Linear Output Card written to only if Linear Output is in
Manual Mode.(MMR bit 0 = 1)
40029 Input Absolute Value (Hi word)
N/A N/A N/A Read Only
Gross value of present Input level. This value is
affected by Input Type, Resolution, Scaling, but not
affected by Offset Value
40030 Input Absolute Value (Lo word)
40031 Input Offset Value (Hi word)
-199999 999999 0 Read/Write
Input Offset Value plus the Input Absolute Value equals
the Relative Input Value (standard meter value).

PAX2A MODBUS REGISTER TABLE
The below limits are shown as Integers or HEX < > values. Read and write functions can be performed in either Integers or Hex as long as the conversion was done
correctly. Negative numbers are represented by two’s complement.
Note 1: The PAX2A should not be powered down while parameters are being changed. Doing so may corrupt the non-volatile memory resulting in checksum errors.
