MB Address in

Specifies the register or digital point address offset within the Modbus
slave device. The MBS Master reads or writes from/to this address
within the slave.
Refer to the documentation of each Modbus slave device for their
register and digital point address assignments.
Note: The value entered here does not need to include the "Modbus
Prefix" addressing scheme. Also, this value is an offset of the zero-
based Modbus addressing scheme.
Example: Using a Modbus Function Code 3 to read from address
40010 in the slave, a value of ‘9’ would be entered in this parameter.
The firmware (internally) adds a ‘40001’ offset to the value entered.
This is the same for all Modbus addresses (0x, 1x, 3x, 4x).
Override
Value Upon
Error
This parameter is only applicable for
Enable Codes
3 (Bit/Word
Override) or 4 (Float Override).
If an error occurs associated to a read command the module
automatically populates the associated database area with this
override value.
