10.2 LAN Communication
10.2.1 Connection
A LAN interface is integrated in the SIMEAS R-PMU in accordance with IEEE 802.3,
10Base-T/100Base-T with a Baud rate of 10 Mbit/s or 100 Mbit/s.
This interface allows SIMEAS R-PMU to communicate with OSCOP P in Client, Evaluation,
DAKON or Server mode via TCP/IP.
Hub/Switch
If several SIMEAS R-PMU or SIMEAS R devices are to be included in a network, a switch is
recommended. When a message is transferred, the switch automatically detects the recipient
device of the message. Thus the switch sends the message only to the device that it is intended
for. This avoids unnecessary load on other devices (receipt of message, processing of
message). Additionally, this ensures that time-critical data (e. g. network trigger, PMU data or
time stamp telegrams) is transferred without delays if possible.
Evaluation PCs/DAKONs with OSCOP P and PDCs can be connected directly to the network or
in another network connected to the SIMEAS R network via one or more routers.
Following are some examples for the creation of such networks.
Note
More detailed information on communication can be found in the Application Description „Com-
munication SIMEAS R/SIMEAS R-PMU“, or number E50417-X1074-C402, under
