Communication

The busbar tap-off unit with AKM measurement
technology has the following listed data interfaces
for communication with other instances.
INFORMATION
· The arrangement of the data interfaces on the
AKM can be found in chapter „Interfaces" auf S.
64.
· Detailed information about communication and
data interfaces can be found in the usage infor-
mation of the installed measurement devices.
3.10.1 Ethernet interface (standard, exception
AKM 103)
The Modbus TCP/IP communication takes place
via an industry standard RJ45 interface, which
leads from the measurement device to an RJ45
connection socket on the AKM.

3.10.2 RS-485 interface (standard)

Mode RTU communication takes place via 2 RS-
485 interfaces leadi ng from the measurement
device connections to a socket and a plug on the
AKM. This makes it easy to implement master-sla-
ve topologies.

3.10.3 Digital input (option)

The digital input of the measurement device is also
provided as a socket on the AKM. The optional di-
gital input (S0 input) is used, for example, to record
the consumption of compressed air or coolant.
The measured values of the equipment (consumer)
connected to the digital input are stored in the
installed measurement device and can be evalua-
ted and analyzed, for example, using the GridVis
software.
The AKM with the "digital input" option includes a
24 V power supply unit to supply external devices.
The following types have the "digital input"
option:
AKM 96RME
AKM 96RMPN
AKM 96PA
AKM 96PAMID
AKM 96PQL
