4. Considering the scanner's limited memory for storage of the ADR configuration, more
than one scanner will be required if there are many MM200 relays in the DeviceNet
network.
The device profile is an extension of the Communications Adapter Device Profile (0xC0). It is
a group 2 only server. The MAC ID and baud rate are programmable through the EnerVista
MM200 Setup software. The MM200 supports the following DeviceNet object classes.
CLASS
01H
02H
03H
05H
A0H
B1H

A1H
A2H
The MM200 supports poll and explicit messaging types.
The Poll function consumes one byte of control data (described under User Object Class
B1h, Instance 01h, Attribute 01h) and produces 38 bytes of status and metering data as
described in User Object Class A0h, Instance 01h, Attribute 01h.
USINT, UINT, UDINT and DINT, stated in this document, stand for the following data types :
USINT = Unsigned integer byte
UINT = Unsigned integer word
UDINT = Unsigned integer double word
DINT = Signed integer double word
The Polling function consumes one byte of control data and produces 38 bytes of status
and metering data as described in User Object Class A0h, Instance 01h, Attribute 01h. The
control data format is as follows:
