The "sc show net" command displays the devices in the system network and shows additional
information about these devices.
Because both these functions rely on SNMP (Simple Network Management Protocol), only
SNMP-capable devices will be found. SNMP as of version 2.6 is available for Linux-based
devices, for all other devices (e.g. MCP) this depends on the associated software version. If
a simple call is made without any additional options, a list of the devices found will appear
showing the relevant IP address, DNS name (if known), and a short description (module name).
Options
The various switches, which can also be combined, allow additional information to be output
on the devices found:
● Unless additional options are involved, the output format for "sc show net" is designed to
be displayed on the screen. The alternative XML format is preferable, however, if further
machine-based processing is required. This can be selected via the -xml option (this option
must be the first one!).
● If the command line contains nothing after the switches, "sc show net" will search the
complete system network via broadcast for devices able to use SNMP. This search takes
time, however, and in the case of larger systems, the volume of information output can be
considerable. In view of this, a list of IP addresses or (DNS) names can be specified to
ensure a better overview. This will limit the search process and only the named devices will
be included.
-hw Information on hardware, such as the MLFB, serial number, hardware ID,
hardware version, SRM version, manufacturer, and the serial number of the
CompactFlash Card. Some devices have two of these hardware blocks (the
second one being intended for an integrated device).
The PLC in the NCU and the TACO in the OP on an TCU are two such ex‐
amples.
-tco Operating state data: Switch-on counter, operating hours counter, quantity of
data written to the CompactFlash Card, number of times maximum tempera‐
ture exceeded.
-loc Location data: Location, function, and contact details for the device (if config‐
ured there).
-sw Displays brief details of the software installed, only the version of the overall
status (or of the basic system if only this is installed).
-swfull Displays all the installed software components. They are represented hier‐
archically in the form of a tree. The following is provided for each component:
Information about the version, internal version (if different), target version (if
different), version details, and the installation path.
-panel: Displays panel-specific data: Size and color depth of the display, MCP/TCU/
DCK/EKS index, and the VNC server currently represented
-dhcp Data about a synchronizing DHCP server: Operating state (off/standby/ac‐
tive), priority, versions of the lease file and TCU data, and the range for dy‐
namically assigned IP addresses
