4 Functionality
4.1 Data Exchange support
The COM200 module is based on IP network and SMS services. The DLMS protocol is
used for data exchange between electricity meters and HES. The HES acts as DLMS client
and the E-meter as DLMS server. The following communication services are provided:
•
GPRS
•
CSD/SMS (Wake-up)
Two operating modes can be used:
•
Pull mode
•
Push mode
The “Pull” mode is initiated by the HES. It is used for collecting data from meters or sending
commands to meters and consumer’s interface. The “Pull” is using following DLMS services:
•
OPEN
•
RELEASE
•
GET or SET
•
Action
The “Push” mode is initiated by the meter to send critical information such as Alarms and so on
to the HES. The DATA-NOTIFICATION service of DLMS is used in this mode. Following table
