5: Communication Installation
The Shark® 100/50 meter is designed in four forms that each have communication
capability. The first form uses RS485 serial communication. This allows the meter to
be wired in a daisy chain connection along with other meters, and to communicate
data back via serial protocol. The available protocols are Modbus RTU/ASCII or DNP3.
NOTE:
The RS485 option is the only communication mode available for the Shark®
50 meter.
The second form of the meter is the Shark® 100 - INP10. This meter provides similar
communication capability, but communicates over a 10/100BaseT Modbus TCP/IP
Ethernet connection.
The third form of the meter is the Shark® 100B. This unit adds the capability of
communicating over BACnet/IP. This allows the meter to act as a BACnet server and
to transfer data to a BACnet client over an IP architecture. This meter also provides a
basic web interface and a Modbus TCP/IP connection.
The fourth form of the meter is the Shark® 50B. This unit adds the capability of
communicating BACnet MS/TP through serial RS485. This meter also provides a basic
web interface and a Modbus TCP/IP connection.
5.1: Shark® 100/50 Meter Serial Based Communication
The basic Shark® 100 meter provides two independent Communication ports. The
first port, Com 1, is an optical IrDA port. The second port, Com 2, provides RS485
communication speaking Modbus ASCII, Modbus RTU and DNP3 (V3 and V4)
protocols. The Shark® 100B meter and Shark® 100 with the INP10 option have an
RJ45 port instead of an RS485 port (see Section 5.3). The Shark® 50 meter has the
RS485 port as an option, but no IrDA port. The Shark® 50B meter has both RS485
and an Ethernet option, but no IrDA port; its RS485 port is dedicated to BACnet
communication, and its Ethernet port to Modbus TCP/IP communication.
