●DM Area Setup

• DM Fixed Allocation Words for Modbus-RTU Easy Master

DM settings from D32300 to D32305 (CP1E: D1201 to D1205) are set before the

execution of the ladder program.

D32306 and D32307 (CP1E: D1206 and D1207) do not need to be set explicitly.

They are modified by MOV instructions, and are used to change, start, and stop

frequency commands.

• Operation Command (Register No.0001 Hex) allocation and details for

Inverter V1000

For this example, only operation command (No.0 bit) will be used.

• With Modbus-RTU easy master function, CRC-16 checksums do not need to be

set in the DM area, since they are calculated automatically.
