Variable Area (Setting Range) List - Omron E5CN-HT Communications Manual

SECTION 5 Communications Data for Modbus

5.1 Variable Area (Setting Range) List

• 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 specifying 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.
