netSWITCH for SERCOS III
The SERCOS III Real-Time Ethernet system provides deterministic jitter-free data
transmission for controlling and synchronizing drives. Parallel to this and based
on a time-slot basis, standard Ethernet telegrams can be transmitted via a NRT
(Non-Real-Time) channel. These NRT telegrams must be buffered for retransmission
on a standard Ethernet network. The netSWITCH provides this buffer connection
between the sycronized SERCOS III network and standard Ethernet.
Besides the two Ethernet ports for SERCOS III, there is one Ethernet
port for connection to a notebook or other standard Ethernet capable devices.
In the SERCOS III network, SERCOS III telegrams and Ethernet telegrams
on the NRT channel are received by the netSWITCH. The Ethernet
telegrams of the NRT channel are forwarded by the netSWITCH to the
standard Ethernet ports making these messages available to users outside
the SERCOS III ring. Likewise standard Ethernet telegrams that are received
by the netSWITCH are inserted into the NRT channel of the SERCOS III
network for delivery to SERCOS III components.
The netSWITCH forwards the SERCOS III real time telegrams with a
throughput time of 600 ns. NRT telegrams are processed according to the
Store-and-Forward principle.
Configuration
For configuration, settings must be made to the time slot of the SERCOS III
NRT channel (starting time t6 and ending time t7). This can be done using a
web browser.
Status and Diagnostic
LEDs are available at the netSWITCH for control of communication and
status of the device. Additional status and diagnostic information can also
be read from the netSWITCH with the use of a web browser.
