The meanings of the values in these groups are well defined by standard literature. However, the
contents of some values are implementation-specific. This section explains contents of values
specific to the PNC.
Interface Number
Many MIB-II groups use an SNMP interface number to refer to a device port. For the PROFINET
Controller module the interface numbers are:
Physical Port
SNMP Interface Number
External Port #1
1
External Port #2
2
External Port #3
3
External Port #4
4
Internal Data Port

MIB-II Interface Group Values
For the MIB-II Interface Group, the
ifDescr
value provides a textual description of the corresponding
interface/port. The values returned for that item are the same as the port numbers listed above.
The counters
ifInDiscards
and
ifInUnknownProtocols
are always reported as zero.
MIB-II System Group Values
Many of the items provided by the MIB-II System Group are implementation-specific. The values
that are returned for the PNC are described below.
Name
Value
sysDescr
Text description of the device being managed. For example:
GE Intelligent Platforms PROFINET IO-Controller, IC695PNC001
sysObjectID
Uniquely identifies the kind of device being managed. The first part of the value
returned (1.3.6.1.4.1.24893) indicates that this is a GE Intelligent Platforms
device. The two numbers after that (1.5) indicate that it is a product made for
the Control Systems Business. The three numbers after that identify (in order):
Family: RX3i = 1
Product: PROFINET Controller = 2
Model: (specific to each Family/Product combination)
For the RX3i PNCr: 1.3.6.1.4.1.24893.1.5.1.2.1
sysContact
Nothing (empty string)
sysName
The Device Name assigned to the nod
e. If the Device Name hasn’t been
assigned yet, an empty string is returned.
sysLocation
Nothing (empty string)
sysServices
79 (0x4F)
This value indicates the PROFINET Controller has Layers 1
–4 (physical,
datalink, network and transport) and Layer 7 (application) functionality.
