3.1.1.2. Write File Record (21)

The Write File Record command writes multiple groups of file registers to the Modbus slave.

Note that file registers are referred to by several different names in the Modbus specifications. They are variously called "file records", "registers" and "references" in the current Modbus specification, and they are called "General References" or "Extended Memory file (6x) references" in the original Modbus specification and the Modbus/TCP specification (with this command being called "Write General Reference").

To add a register group to the request, click the Add button and then enter the group details in the File Register Groups table:

To remove a register group from the request, select the group in the table and click the Delete button.

The register values to be written should be entered in the Value column of the Data to be written table.
