Part No. 750-366

2.4 Communications

2.4.1 Modbus

Modbus is an open serial protocol used by the HAWK 1000 system for sending  and  receiving control
commands, position data,  and diagnostic data  between  the PLC and  attached devices. Modbus
communications are managed  by the SM2 module  located  to the right of the  base unit  in slot  4.

HAWK 1000 devices that communicate using Modbus include the burner flame safety control and the fuel, air,
and FGR actuators. The Modbus communication network allows burner control system status and fault
information to be transmitted to the PLC and displayed on the HMI screen, and in addition is used for actuator
control, feedback, and fault information.
