7.2.1.2.7 Network Trigger
If several SIMEAS R-PMU are combined to form a local network (LAN), the triggered device can
use the network to send UDP broadcast telegrams to the other SIMEAS R-PMU devices and
start a TAR fault recording there. The subnet is defined via
IP Address SIMEAS R-PMU
and
Subnet Mask SIMEAS R-PMU
, see chapter 12.7.2 and chapter 10.2.2.
You can set separately, whether the SIMEAS R-PMU is to send network trigger signals or to
evaluate incoming network trigger requests. If incoming network trigger requests are evaluated,
only the TAR is able to start a retrigger. Retriggering is not possible via a new network trigger. If
SIMEAS R-PMU receives a network trigger, the trigger time stamp indicates the receipt time of
the network trigger.
If SIMEAS R V2/3 devices are also used in the same network, the SIMEAS R-PMU can evaluate
a network trigger received from these devices and start its own record. The opposite case, i. e.,
that the SIMEAS R V2/3 device starts a fault record upon receipt of a trigger from a SIMEAS R-
PMU device, is only possible if both devices refer to the same time base.
