Changelog:

0.9.0
– First version using the S7online interface

0.9.1
– added optional monitoring of the data exchange

0.9.2
– Fixed bug: Data exchange with plcsim doesn't hang up any more, 
  when packets of some PDU sizes occur
- Check of the running IEPG-Helper servicename to stop/start
  service in Windows 32 or 64 Bit OS
– Added Command-Line Arguments, and the possibility to Drag&Drop
  a configuration file on the NetToPLCsim.exe

0.9.3
– Temporary fix: Implemented own response for SZL-ID 0x0131 index 3
  request, to force clients not to use the cyclic data exchange
  mechanism, which causes sometimes communication failures
– Usability: Automatic name generation when a new station is added

0.9.4
- Nettoplcsim answers a client that only one single request at time
  can be handled (MaxAmQCalling/MaxAmQCalled)
- Added optional setting for rack/slot combination of CPU (maybe 
  possible to connect to TIA-Portal Plcsim)
- Added option for TSAP check corresponding to entered rack/slot.
  Connection ressources 1,2 or 3 are valid (1=PG, 2=OP, 3=S7basic)
- Protocol monitor: requested index and ID of SZL requests are shown

0.9.5
- Adding Tool „Get Port 102“ in Menu Tools, which helps to get 
  Nettoplcsim working under Step 7 V5.5 SP2 and Windows 64 Bit

1.0.0
- Nettoplcsim supports now the full functionality of Plcsim.
  Programming functions like up- and downloading of program blocks
  and online diagnostics are possible. Also block-specific messages
  (like ALARM_S, ALARM_8) and cyclic variable services are supported.
- Added own response telegram to SZL-ID 16#0x74, used to get the LED
  state of the CPU. Independent of the operating mode, the response
  is always RUN-LED on, and all other LEDs off.

1.1.0
- Fixed: if many ISO packets were sent in a single TCP telegram, 
  this may have caused an exception and disconnect (for V.1.0.0)
- Added support to S7-Plcsim for TIA-Portal S7-1200/1500
- Function "Get Port 102" from tools-menu is now executed on program
  start to stop the Siemens service
- Monitor window: With mouseclick on statusbar the capturing can be
  paused and resumed
- New documentation using Windows-Help files
- Changed license from GPL to LPGL

1.2.0
- Fixed: Handling of the station-name used in the function to browse
  the reachable Plcsim partners. Fixes the problem that sometimes no
  Plc was found, or an exception occured.
- Increased the timeout to stop the S7DOS service and added an
  optional second try, to prevent that a timeout occurs on slow
  machines.

1.2.1
- Fixed: Reading multiple TPDUs from TCP-stream corrected.
  Data from client applications which used to send more than one
  unacked PDU are now processed without problems.
- Protocol monitor: show requested variables in cyclic variable
  services

1.2.2
- Fixed: Received ISO packets with a length less than 5 bytes were not
  transferred to Plcsim. This is possible in fragmented ISO packets.

1.2.3
- Fixed: Fixed memory leak, which may lead to a crash of NetToPLCsim 
  with "Out of memory".

1.2.4
- Improvement: Take the negotiated TPDU size into account for all
  further packets.
- User interface: Improved dialog to browse and show the available
  IP addresses of the network interfaces.

1.2.5
- Fixed: Some Wi-Fi network interfaces are now displayed in the browse
  dialog. Added an option to show all available network interfaces.
