Network Protocol Reference

Writing in Holding Registers [10h]:

This function writes data in consecutive holding registers. An example follows:

•Write “3000 seconds” as the first acceleration time 1 (F002) in an inverter having a slave address “1.”

•This example uses change data “300000(493E0h)” to set “3000 seconds” as the data resolution of the registers “0024h” and “0025h” holding the first acceleration time 1 (F002) is 0.01 second.
