IQ 150S C: DNP Map
C: IQ 150S Meter DNP Map
C.1: Introduction
The IQ 150S meter’s DNP map shows the client-server relationship in the meter’s use of DNP
Protocol.
C.2: DNP Implementation
PHYSICAL LAYER
The IQ 150S meter can use RS485 as the physical layer. This is accomplished by connecting a PC
to the meter using the meter’s RS485 connection (see Chapter 5).
RS485
RS485 provides multi-drop network communication capabilities. Multiple meters can be placed on
the same bus, allowing for a Master device to communicate with any of the other devices.
Appropriate network configuration and termination should be evaluated for each installation to
insure optimal performance (see Chapter 5).
Communication Parameters
IQ 150S meters communicate in DNP 3.0 using the following communication settings:
• 8 Data Bits
• No Parity
• 1 Stop Bit
• Baud Rates: 9600, 19200, 38400, 57600
