Autocrossover
Mechanism with which a TP port is automatically switched over
between MDI and MDI-X pinning to establish a connection regardless
of the port pinning of the device being connected. This makes the use
of crossover cables unnecessary.
The autocrossover function is available only when the port is set to
autonegotiation mode.
Autonegotiation
Procedure standardized by IEEE 802.3 in which the transmission
parameters (for example 10/100 Mbps, full/half duplex) are negotiated
automatically between the devices.
Auto Polarity
Exchange
Procedure in which the module automatically detects incorrect
attachment of a cable to the electrical OSM/ESM port (RD+ and RD-
swapped over). The OSM then reverses the polarity automatically.
Autosensing
See Autonegotiation
Backbone
In conjunction with the OSM/ESM, this means a bus or ring structure
made up of interconnected OSM or ESM modules that form the
backbone of an industrial LAN.
Display Mode
The display mode LEDs indicate the display mode in which the port
and power LEDs and the attached input signals (OSMs/ESMs with
digital inputs only) of the OSM/ESM are currently working. The display
mode can be changed with the button on the front panel of the
OSM/ESM.
ESM
Electrical Switching Module. SIMATIC NET Ethernet switch with
electrical ports
Fault Mask
The fault mask specifies which ports (ports 1 - 8) and power supply
terminals (line 1/2) are monitored by the signaling contact. The fault
mask can be set again with the button on the front panel of the
OSM/ESM.
Filtering
OSMs/ESMs learn the addresses of the devices that can be accessed
via a port. They redirect the packets intended for this device only via
this port.
ITP Port
Port with Industrial Twisted Pair (ITP) connector (sub D 9-pin female)
