SNAP-B3000-Modbus I/O Configuration
Tables of Configuration Types, Values, Scaling
These tables show the values for Holding Registers 33–48 in the
Mapping Information table on the previous page. Part numbers are
shown for analog inputs and outputs. Both points on a module
must be configured the same. All temperatures are in degrees C.
Analog points also show the scaling used for the I/O type and the
default for this type. Scaling allows a floating point to be returned
as an integer. To find the actual value, divide by the scaling number.
For example, if a value of 4,128 is returned for a single-channel 4–
20mA analog output, divide 4,128 by 1,000 to obtain the actual
value, which is 4.128.
