5.3 Ethernet mode
With Ethernet mode a SUT50 can be connected via LAN interface with a
Videomatrix SIMATRIX NEO or SIMATRIX SYS.
Communication utilizes the UDP/IP protocol and port 7000. The IP address is
arbitrary.
The UDP/IP protocol is characterzied by minor delays and the avoidance of time-
consuming connection establishment. The UDP procotol underlying ethernet proto-
col layer prevents failures, for example caused by packet collision. It is protected
by CRC error check and has equal or higher transport safety than SIMATRIX
proctocol via V24 or TTY interface.
5.3.1 Connection state
If a connection between the HMI device and the server or console router is
established the green LED lights constantly. If the connection is interrupted the
LED flashes (with a delay up to 30 seconds, so the interruption is not indicated
instantly)
If an in IP address conflict occures the LED flashes red. Please verify that the IP
address of the device is not used already.
5.3.2 Network topology
It is possible to use the SUT50 in existing network-infrastructures like offices,
where PCs are connected as well.
Please be aware of delays that may occur when the network traffic is charged with
large amount of data. This affects both directions of communication of the SUT50 -
sending and receiving data.
5.3.3 Network router
A connection via network router is possible. Although in this case the HMI device
can not detect a physically interrupted connection to the server and thus will not
indicate this failure by LED.
