2. Function
The EMG 1500–PN Gateway serves as interface between the
Ethernet and the FRAKO Starkstrombus
®
.
2.1 Operating principle of the EMG 1500-PN
Polling signals are sent to the EMG 1500-PN via the Ethernet.
These are converted into polling commands in the FRAKO
Starkstrombus
®
. The response from the instrument addressed is
then returned via the Ethernet. The EMG 1500-PN Gateway is
capable of serving several Ethernet connections simultaneously.
2.2 Communication with the EMG 1500-PN
Various programs and devices can be linked to the EMG 1500-PN
Gateway.
•
The SYSTEM-SW is used to configure the EMG 1500-PN.
•
The EMIS 1500 central unit uses the EMG 1500-PN to access
the individual instruments in the Energy Management System
and collect their data.
•
The Setup programs for the individual EM (Energy
Management) instruments such as EMA-SW, EMR-SW or
OPT-SW, are also able to be connected to the appropriate
instruments via the EMG 1500-PN.
2.3 Connections
The EMG 1500-PN is provided with connections for the power
supply (230V AC) and three communications connections.
•
an RJ-45 Ethernet jack
•
a FRAKO Starkstrombus
®
connection (RS 485)
•
an RS 232 connection (9-pin D Sub)
2.4 Display
The EMG 1500-PN has 4 LED annunciators. If the Run LED
flashes, this indicates that the instrument is working correctly. The 3
other LEDs indicate the status of data transmission
(see Section 5.1, page 12)
