Gateway Management Function
The gateway supports SNMPv1 and SNMPv2c to exchange gateway and network-specific
management information with dedicated tools. The data content is defined in various
specifications and allows mainly to monitor the health status of network components, provided
that information is organized in so–called management information bases (MIBs) that various
standards define. Supported MIBs are:
■
MIB-II
■
LLDP-MIB
■
LLDP-EXT-DOT3-MIB
■
LLDP-EXT-PNIO-MIB
The gateway supports mandatory information defined in the specific standard.
3.4
Supported PROFIBUS PA Device Features
PROFIBUS PA devices complying with PROFIBUS DP-V0 and DP-V1 are supported. The
gateway supports following PROFIBUS PA communication features:
■
SET_PRM
■
SET_CFG
■
C2 communication
■
Diagnostics, including structured diagnostics
■
Module PRM parameters for PROFIBUS PA devices not supporting structured PRM
■
PROFIBUS I&M functions
■
RD_INPUT
■
RD_OUTPUT
■
GET_CFG
■
Acyclic C1 communication
■
Set_Slave_Address
The following PROFIBUS features are not supported because PROFIBUS PA devices cannot
support them:
■
Alarms
■
EXT_PRM
■
Module PRM parameters for PROFIBUS PA devices using structured PRM
■
PROFIBUS PA channel diagnostics
3.5
Cyclic IO Data of the PROFIBUS PA Devices
The PROFIBUS PA device slot data is mapped into gateway subslots.
For each PROFIBUS PA segment a maximum of 46 devices can be addressed, each
supporting 246 bytes of input and output data. The device address range is defined from
3
…
49. For each PROFIBUS PA segment, a fixed slot cluster is defined with a length of
46 slots. For more information, see chapter 3.2.
Example: Device data of PROFIBUS PA device address 5 in segment 3 is available in slot 155.
3.6
PROFIBUS PA Device Diagnostics
PROFIBUS PA SLAVE_DIAG data is mapped to PROFINET diagnostics alarms as defined in
the PROFIBUS PA GSD file. Channel-specific diagnostics for PROFIBUS PA devices is not
supported.
