3. EXAMPLE: USE MODBUS COMMANDS TO CONTROL TWO RELAYS

Using BASE 0 addressing, alarm relays are controlled by writing to holding register 0x006F.
Bit 0 controls Relay 1. Bit 1 controls Relay 2.

First Alarm1 is forced by writing 01

01 to holding register 0x006. This turns Relay1 on.

Then Alarm2 is forced by writing 03

03 to holding register 0x006. This turns Relay2 on.

Both relays are turned off by writing 00

00 to holding register 0x006. The setup for this last

command is seen in the qModMaster window.

The Bus Monitor window displays the result of all three write commands.
