QUESTION:
Which variables are supported by SNMP or by SIMATIC NET?

ANSWER:  
In the following is an overview of possible functions/variables of SNMP (MIB II) that are significant for monitoring the device status:

  • System Group
sysDescr
sysName
sysLocation
sysUpTime

Designation

Access rights

Description

sysDescr

read only

A string of up to 256 characters is used. This value contains the name and version Ids, the software operating system and network type, i.e. for an OSM, for example, OSM TP62, and for a CP343-1 the S7300 station.

sysObjectID

read only

Output of the object identifier under which the component is to be reached in the Siemens MIB tree: "1.3.6.1.4.1.4329.6.2.nnn.mmm"
If no private OIDs have been declared, then the object identifier [0,0].

The value 0 is preset here.

sysUpTime

read only

Counter in hundredths of a second after the last reset (e.g. after Power Up).

The value is preset here.

sysContact

read and write

Provided by the network manager (default: empty).

Possible value is a string of up to 256 characters.

sysName

read and write

Provided by the network manager – in compliance with convention of the full-qualified domain name. Default: empty

Possible value is a string of up to 256 characters.

sysLocation

read and write

Provided by the network manager (default: empty). Describes location of the device - preset.

Possible value is a string of up to 256 characters.

sysService

read only

Displays the set of services that are provided by the component as per ISO/OSI model. 
Level functionality:

  1. physical (e.g. repeater)
  2. data link/subnetwork (e.g. bridges, switches)
  3. Internet (e.g. IP gateways, routers)
  4. end to end (e.g. IP hosts)
  5. applications (e.g. e-mail server)

The value is a preset integer 32 bit.

Table 1: System Group Parameters

  • Interface Group

Designation

Access rights

Description

ifNumber

read only

Number of different interfaces available in the component. Generally only one interface is available in SIMATIC NET. A total number is given even if not all the interfaces are ready for operation. An interface is, for example, the Ethernet connection of a CP to the TCP/IP batch. Another interface would be, for example, the IP path "local host".

The value is a preset integer 32 bit.

ifDescr

read only

This value includes information about the interface. This string should contain the name of the manufacturer, the product name and the version of the interface. 

Example with CP343-1:
SIEMENS SIMATIC NET CP343-1 6GK7343-1EX20-0XE0 HW: Version 1 FW: Version 1.1.10 Fast Ethernet Port 1 Rack 0 Slot 4

A string of up to 265 characters is used.

ifType

read only

The value "ethernet-csmacd(6)" is entered for SIMATIC NET.

Other possible values:
other(1), -- none of the following
regular1822(2),
hdh1822(§),
ddh-x25(4),
rfd977-x25(5),
ethernet-xsmacs(6),
iso88023-csmacd(7),
iso88024-tokenBus(8),
iso88025-tokenRing(9),
iso88026-man(10),
starLan(11),
proteon-10Mbit(12),
hyperchannel(14),
fddi(15),
lapb(16),
sdlc(17),
dsl(18), -- T-1
el(19), -- the European version of T-1
basicISDN(20),
primaryISDN(21), -- system-specific, serial interface
propPointToPointSerial(22),
ppp(23),
softwareLoopback(24),
con(25), -- CLNP via IP
ethernet-3Mbit(26),
nsip(27), -- KNS via IP
slip(28), -- generic SLIP
ultra(29), -- ULTRA Technologies
ds3(30), -- T-3
sip(31), -- SMDS
frame-relay(32)

The value is a preset integer.

ifSpeed

read only

Estimated value over the nominal bandwidth of the interface in bits per second. In SIMATIC NET either 10 Mbit/s or 100 Mbit/s displayed. 

The value is of the data type "Gauge".

ifOperStatus

read only

Value from list:
up(1),
down(2),
testing(3),
Current operating state of the interface is given here.
The state "testing(3)" indicates that no user data is being transported.

The value is a preset integer.

ifLastChange

read only

Counter in hundredths of a second. Counts how long the interface has had its current operating state.
If the state was reached before the last reinitialization by the SNMP manager, then the value is zero.

The preset value is of the data type "TimeTicks".

ifInErrors

read only

Counter of the packages which have been received but not forwarded to the higher protocol levels because of detected errors.

The preset value is of the data type "Counter".

ifOutErrors

read only

Counter of the packages that have not been sent because of an error. 

The preset value is of the data type "Counter".
