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 2100 should not be powered down while parameters are being changed. Doing so may corrupt the non-volatile memory resulting in checksum errors.

For Input Registers, replace the 4xxxx with a 3xxxx in the above register address. The 3xxxx are a mirror of the 4xxxx Holding Registers.
2
An attempt to exceed a limit will set the register to its high or low limit value.
Bit State: 1= Reset Output; Bit is returned to zero
following reset processing
Bit 3 = SP1, Bit 2 = SP2, Bit 1 = SP3, Bit 0 = SP4
Status of Setpoint Outputs: Bit State: 0=Off, 1=On,
Bit 3 = SP1, Bit 2 = SP2, Bit 1 = SP3, Bit 0 = SP4
Outputs can only be activated/reset with this register
when respective bits in Manual Mode (MMR) register
are set
Bit State: 0=Auto Mode, 1=Manual Mode
Bit 4 = SP1, Bit 3 = SP2, Bit 2 = SP3, Bit 1 = SP4,
Bit 0 = Linear Output
Functional only if Linear Output is in manual mode
(MMR bit 0 = 1). Linear Output Card is written to only
if Linear Out (MMR bit 0) is set
Gross value of present Input A level. This value is
affected by Input Type, Resolution, Scaling, but not
affected by Offset Value
Gross value of present Input B level. This value is
affected by Input Type, Resolution, Scaling, but not
affected by Offset Value
Relative Input Value (standard meter value) is sum of
Input Offset Value and Input Absolute Value
Relative Input Value (standard meter value) is sum of
Input Offset Value and Input Absolute Value
