Hawk 1000 Section 2 — System Components
Part No. 750-366 2-5
2.4.2 Ethernet
The
HAWK
1000
uses Ethernet for several communication functions:
• Communication between the PLC and HMI. The Ethernet cable connecting the PLC and HMI can be either
a straight through or a crossover type.
• Connection of the boiler control system to an existing infrastructure, i.e. plant Local Area Network (LAN)
• Integration with a Building/Plant Automation System (BAS)
• Remote monitoring of boiler control system via the customer's Wide Area Network (WAN) or via the Internet
• Connection of a laptop for diagnostics
Ethernet/IP is also used for control functions. Individual boiler controllers may be networked to facilitate lead/lag
control, with a single BAS interface for multiple boiler systems.
2.4.3 USB
USB communications are used to connect a laptop computer for diagnostic purposes.
