SECTION 6 Communications Data for Modbus
6-2
6.1 Variable Area (Setting Range) List
The following table lists the variable areas. Items expressed in
hexadecimal in the “Set (monitor) value” column are the setting range in
the Modbus specifications. Values in parentheses “()” are the actual
setting range.
When there is a section reference for a setting item, refer to that
reference for details.
