Changes introduced with V4.7.0 - INTERMEDIATE information for next upcoming version

...

This section shows changes introduced with firmware V4.7.0.

General changes and remarks

• if I&M5 functionality is enabled, the firmware no longer automatically adds the additional "OEM ID" block to DCP frames
  • A new ParameterTypes of PNS_IF_SET_OEM_PARAMETERS_REQ was added to explicitly activate this block
• Profinet related IP frames are now sent with a VLAN tag to give these frames the priority recommended by Profinet specification
  • IP frame generated by other instances (integrated webserver, Socket API) are not affected
• if feature SecurityClass 1 is enabled, the behavior regarding SNMP has changed (off by default) to match new revision of Profinet specification
  
  • please check Protocol API Manual for more details regarding Profinet Security
• a dedicated technical datasheet document is delivered for each individual firmware stating the capabilities and limitations of the specific firmware
• Support of ReductionRatio which is not a power of 2 was removed and is no longer useable. This limits possible network update times.
• RAM based cifX hardware (e.g. CIFX 50-RE) is now able to store remanent data
• Support for SecondStage Bootloader V1.7.0 (and newer) was added
  • This allows using a larger variety of serial flashes

Packet handling (API changes)

The following services have changed starting with firmware V4.7.0.

...

Support for the following parameter types have been added:

• ParameterType 21

Tag list

No tag list changes with firmware V4.7.0 compared to V4.6.0.

Changes introduced with V4.6.0

This section shows changes introduced with firmware V4.6.0.

General changes and remarks

• The netX 52 firmware no longer supports (in total) 3 IO ARs but 2 only. With earlier released versions it was possible to change the number of ARs in the tag list to 3 and the firmware successfully has started. This is no longer possible due to resource constraints.

• The netX 52 firmware no longer supports 2 parallel ReadImplicit Requests at the same time. This is no longer possible due to resource constrains.

• Major internal rework has been done including a major update of the integrated IP stack. The firmware now is quite similar to Hilscher PROFINET IO-Device V5 firmware used for netX 90. This is by intention.

• The firmware supports the newly designed Device Data Provider (DDP) now.

• All firmware no longer use device identity parameters set via tag list of SecondStage Bootloader (HW Data). Any setting made in this specific tag in SecondStage Bootloader will be ignored by the firmware.

• The evaluation of OrderID and HardwareRevision from the SetConfiguration packet has been removed. The firmware expects the fields in SetConfiguration Request to be set to 0. Instead the firmware will always use the values provided in the Device Data Provider (DDP), which matches by default the values from the Security Memory or Flash Device Label (FDL). These values can be changed using service HIL_DDP_SERVICE_SET_REQ (0x1EEC).

• OrderID from SYCON.net database file is no longer evaluated. Instead the OrderID of the DDP is used which is either configured from the Security Memory or FDL.

• In case, the PROFINET IO-Device protocol stack is not configured, the firmware will no longer automatically enable the PHYs integrated in netX.

  • Once the PROFINET IO-Device protocol stack is configured, the PHYs will be enabled with parameters contained in the remanent data. If Autonegotiation is used after the protocol stack configuration it may take additional 3 seconds until the link is established.

  • A tag list is added to the firmware that allows configuration of a timeout after which the PHYs have to be enabled even if PROFINET IO-Device protocol stack is not yet configured.

• The firmware supports the Hilscher netIdent protocol by default. The UDP port “25383” is thus active and reachable by port scans.

  • A tag list has been added to the firmware to disable the netIdent protocol function.

• The IP stack integrated in the firmware will not be deconfigured if the PROFINET IO-Device protocol stack is switched to “bus state off”. Instead the IP parameterization is kept and all IP-based services continue to work.

  • However, the PROFINET-related protocols like DCP or RTA will be deactivated on “bus state off” as well as the integrated RPC Server used by PROFINET IO-Device protocol stack.

• Firmware offers supports for PROFINT Security Class 1 features

  • As no certification exists for the required features, we cannot guarantee a completely correct implementation. Our own tests show expected behavior.       
    Use at your own risk.

• Socket API quantities can be configured via tag list now.

• Some ParameterTypes of PNS_IF_SET_OEM_PARAMETERS_REQ have been removed.

• In case of error, some services no longer return any data in the confirmation packet.

• New service for Isochronous Applications has been added allowing to generate a user defined signal. Independent from this new feature, this firmware supports applications with the following scenarios

  • netX 100/500: 500 µs network update time and DPM update time, up to 2 submodules each 4 byte.

  • netX 51/52: 1 ms Network update time and DPM update time, up to 2 submodules each 4 byte.

• Sync signal is now always generated, independent if IRT is configured or not

  • Without IRT configuration the firmware internal scheduler cycle is used as base for sync signal.

  • Previous firmware versions did only generate this signal when IRT was configured and active.

• The sync signal now is “high active” instead of “low active”.

• Configuration with iniBatch database (generated by “netX Configuration Tool”) is no longer working. It was never officially supported and thus this will not be fixed. iniBatch configuration must not be used.

Packet handling (API changes)

The following services have changed starting with firmware V4.6.0.

In general, the check for the packet header field “ulLen” of request packets has been intensified in this version. Only the exact packet length is accepted now. Previous released versions accepted request packets with values for ulLen larger than required for the service.

...

• The flag PNS_IF_SYSTEM_DISABLE_STORE_REMANENT_ENABLED in ulSystemFlags is no longer supported. Use the newly introduced tag list entry to control remanent data responsibility.
• The fields abOrderID and usHWRevision are no longer supported and have to be set to 0. These values will always be taken from DDP.

...

Support for the following parameter types have been added:

• ParameterType 19

...

If the service is used with the same USI as an already existing Generic Diagnosis, the old diagnosis entry is silently updated by the new one as indicated by the PROFINET specification.
The service only accepts GenericDiagnosis entries with a severity “fault” and rejects all other severities as this is required by the PROFINET specification.

Changes introduced with V4.5.0

This section shows changes introduced with firmware V4.5.0.

General changes and remarks

• The netX 52 firmware no longer supports (in total) 4 IO ARs but only 3. In earlier releases it was possible to change the number of ARs in the tag list to 4 and the firmware successfully has started. This is no longer possible due to resource constraints.
• In addition to already provided firmware, several additional hardware platforms are officially supported now
  • netX 51 NXLFW
  • netX 100 NXLFW
  • netX 500 NXLFW
  • cifX
  • comX
  • comX 51
  • netJACK 100
  • netJACK 51
• The feature System Redundancy is supported now. However, a special firmware is required (LFW-PNS SR) which has this feature enabled. for identification, the System Redundancy enabled firmware uses Communication Class 0x1A in DPM Channel 0.
  • This feature is and will not be supported by regular standard firmware using Communication Class 0x0A as identifier in DPM Channel 0.
  • This feature is and will not be supported for netX 52-based hardware due to resource constraints.
• By default, IO Supervisor ARs are no longer supported. Support can be enabled at runtime using PNS_IF_SET_OEM_PARAMETER_REQ. This does NOT affect Supervisor DeviceAccess which is still enabled by default.
