Circutor CVM-NRG96 Manual

CVM-NRG96-ITF-BACnet-C
M98238701-03-15A
3.- CVM-NRG96 communication
The unit incorporates BACNet MS/TP communication, following the specifications of
ANSI/ASHRAE 135 (ISO 16484-5). Using a RS485 connection, the analyzer can
connect to a BACnet and include all of the objects and services defined in the
attached PICS map (Protocol Implementation Conformance Statement). Instant,
maximum and NRG96mum variables can be read.
The default speed is 38400 bps and the MAC is 2 (node number), and can be
changed with the keyboard or by writing the BaudRate and MAC_Address variables.
The identifier (Device_ID) can be changed with the keyboard, with write property or
by writing the Device_ID variable. Another option is to write on the Object_Name in
Device:
a) #Baud x – where x may be: 9600, 19200, 38400, 57600, 76800, 115200 bps
b) #MAC x – where x may be: 1 ... 127
c) #ID x – where x may be: 1 ... 4194303
