6-2
• Four-byte Mode
One element uses 2 bytes of data (H'0000 to H'FFFF), so specify two-
element units. Reading and writing in 4-byte units is executed by speci-
fying an even address and specifying the number of elements in
multiples of 2.
• Two-byte Mode
One element uses 2 bytes of data (H'0000 to H'FFFF), so specify one-
element units. Reading and writing in 2-byte data units is executed by
specifying 1-element units.
The following table lists the variable area. 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.
