Revision history of the Tani OPC Servers

Version 2.10.2 - 2024-11-25

• The system tree offers a new variable for checking of changes in the structure layouts. It counts the changes during runtinme.
• Newer encryption functions from 2024 are supported now.
• OPC UA supports the newest specification 1.05 now completely. This was tested intensively in the OPC Interoperability Workshop by the OpcFoundation 2024/10. All the older and now deprecated things from previous specifications are supported also.
• Bugs fixed
• Behobene Fehler
• OPC UA browsing in the client part has been optimized again. An additional request queue saves a lot of network traffic.
• The OPC UA client now accepts self signed certificates from the communication partner if the connection is set for sign and encrypt. The OPC UA specification doesn't allow self signed certificates here, but the effort for signed certificates is high, and in local environments signed certificates can not be created if public certificate companies ship the certificates.
• OPC UA client connection configuration has a minor fix.
• In OPC UA connection works the read only setting again. This was damaged in Version 2.9
• In OPC DA Server connection is a memory leak fixed mainly on calls of Refres2.

Version 2.10.1 - 2024.8.5

• Some minor addenums in OPC UA for features from March 2024 are implemented.
• Bugs fixed
• Behobene Fehler
• A mismatch in writing modbus arrays is fixed.
• In the Siemens S7 300 structure import has fixed. The error was in recursive structure array import.
• In forwarding alarms from an UA server to an UA client a missing RPC function is added. This preventy seldom method invalid errors.
• The GDS Push functionality in OPC UA now supports the certificate revocation lists.
• In the syncronization in connections to any PLC where the PLC runs with event send enabled a race condition is fixed.
• A memory consuming issue is fixed. This did happen in UA server to UA client, and broken connections during the establishing of the OPC UA client connection.

Version 2.10 - 2024.5.22

• New: OPC UA Reverse Connect is now supported conforming to the UA 1.05 specification.
• An expansion for arrays of any kind is made. Now with a setting arrays with one element only will be handled separately as an array. Existing applications most need an array with one element only as a normal variable.
• New: The memory variables now support a quality setting and the NULL state. This allows more complex simulations for modular systems.
• New: Modbus server. Internally this offers registers, coils and imputs. Multiple nodes can exist.Acces simply with symbols or with the Modbus item syntax.

• New: In OPC UA the GDS push functionality for the certificate management is added.
• Bugs fixed
• Now a broken connection to a PLC during the start browse options does not damage structure layouts.

• New: Alarm and event history functionality.
• The diagnostics logger non can track up to three variables separately. Dist is for detecting seldom data mismatches ald seldom slowly data updates.

Version 2.9.2 - 2024.1.24

• With the integrated MQTT broker now PLC variables can be registered. This is hanging on the network connection, if it breaks the registered items will be automatically unregistered after a 30s timeout.

• Bugs fixed
• In S7 1200 model with firmware 3.0.2 and hardware version 2 now inputs and outputs are working.

Version 2.4.2 - 2021.8.10

• OPC DA for Windows now is using more processors if multiple OPC DA clients are used in parallel.

• Now BACnet variables are supported also which have a name, but with nullbytes only.

Version 2.4.1 - 2021.7.23

• Virtual connections new. These are connections only for the rights management. With item redirects multiple lists of items can be created. Virtual connections are transparent for all OPC variants.
• S7 1500 PLC with firmware 2.9, programmed with TIA version 17, now are supported. These PLC have a new S7 protocol.
• Importing structures over OPC UA now is more simple: As in the PLC connections the structures can be chossen oder the variables using them also.
• Bugs fixed

• In handling of OpcPipe another high load effect is fixed. It was triggered by tenthousand of variables which nearly all change treir values frequently. Additionally a high load of writing from the OpcPipe client now does not drop data. The same theoretically can happen under OPC DA or OPC UA. But both OPC variants have more network overhead, so the timing nearly cound not happen.
• In the OPC DA server functionality now calling write confirms do not slow down the general speed if the user implementation of the confirm function is working slowly.
• An error in the Linux historian installer is fixed.
• In the OPC UA client some extensions are build for better interoperability with newer Wago devices.

• Bugs fixed
• The Regor devices now are offering the SSH server on both network adapters.
• Install processes for Windows XP and Windows 32 bit did changed in the search of libraries. The problem was that path settings in older and 32 bit windows are not handled immediately, they mostly will require a reboot.
• In OpcPipe wiht using multiple of tenthousand variables an effect is fixed. This did happen if the elements are created very quickly.
• The status variable functionality of the graphical configuration now allows writing of write only variables. Mostly IEC 60870-5 are offering such variables.
• Siemens S7 1500 models in which the program documentation is not stored in the PLC or which are containing secured program parts now can browse flags, inputs, outputs and timers.

• Browsing variables and nodes over OPC UA, OPC DA and OpcPipe now knows a maximum dept of browsing. This can be configured, the default maximum dept lies at 100. Some clients try recursively browsing all variables on startup. If a loval client connection is connected to a locally server recursively browsing will work endless. The new limit will prevent this.
• A special OPC server installer for Windows XP will be offered now. It supports XP only. OPC DA and UA ist working, all supported PLC and devices can be reached. The graphical software parts as the configuration is not included, please configure the OPC server over the network from a more modern system.

• The NTP client now can be configured for each adapter.
• If the station parameters are changed the server certificates will be actualized. This will happen for the self signed certificates only.
• On boot the first minutes all changes in station things and the system time will checked and on demand will renew the servers certificate details.
