The Siemens TCP/IP Ethernet driver exchanges data between OPC clients and Siemens S7-200, S7-300, S7-400, and S7-1200 PLCs using the TCP/IP Ethernet protocol. The driver talks directly to the S7 PLC using a standard PC network interface card, and does not require additional software packages or libraries. Specialized block read and write optimizations automatically increase the speed of many applications when using CP243, CP343, and CP443 communications processors.
The Siemens TCP/IP Ethernet driver also supports the netLink adapter cable.

- Fixed an issue where ATG on a structure would fail if the END_STRUCT had additional characters (such as a comment).
- Fixed an issue with the TIA Portal Exporter that caused crashes when users provide invalid file paths.
- Added support for Siemens TIA Portal v16.0.0.
- Fixed an issue where TIA Portal offsets could be miscalculated in bit or BOOL arrays.
TIA Portal Tag Export Utility
- ProgramBlock and DataBlock Tags now have comments exported (similar to PLC Tags for all supported TIA project versions).
- Exporter Project Parsing Timeout default increased from 5 minutes to 10 minutes to better handle large project sizes.
- Overall performance improved as well as other user interface enhancements to improve performance and reliability.
TIA Portal Exporter Utility
- Fixed an issue introduced in 6.4. Now S7 String type tag addresses that do not contain a “.LEN” specifier will function correctly when the PDU size of 240 is negotiated by the device or manually set by the user from the Maximum PDU Size parameter in device properties.
- Added support for Multiple Non-Redundant 400 CPUs.
- Tag Comments are now exported in the project's ""Reference Language"" by default.
- Added support for Siemens TIA Portal v126.96.36.199 through v188.8.131.52
- Added support for Siemens TIA Portal v184.108.40.206
- Increased the maximum channel count from 256 to 1024.
- Fixed an issue where a write operation to an array would fail if it hadn't been read.
TIA Portal Exporter Utility
- TIA Portal Exporter Utility now supports TIA Portal V14 SP1 and V15.
- Fixed an issue creating server tags from multi-dimensional arrays.
- Increased the maximum channel count from 256 to 1024.
- Added support for larger PDU sizes of 480 and 960.
Note: Using larger PDU sizes allows for increased throughput and larger array size access from the device. Refer to the device Communication Processor manual for supported PDU sizes.
- Added a new setting called Maximum PDU Size. The driver and device negotiate the highest supported PDU size by starting at this defined setting and no higher. Available PDU sizes include 240, 480, and 960.
- Fixed an issue where atomic data types inside an array of structs were not generated when doing automatic tag generation (ATG).
- Added Chinese language support.
- Support for importing Siemens TIA Portal tags into the Siemens TCP/IP Ethernet driver.
- Requires using the export files produced by the TIA Portal Exporter Utility. The installer for this utility is included with the Siemens TCP/IP Ethernet driver.
- TIA Portal versions supported: TIA Portal V13 SP1, TIA Portal V13 SP2, TIA Portal V14.
Note: V14 SP1 is not currently supported.
- Includes German language support.
- Fixed a bug where atomic data types inside an array of structs were not generated when performing Automatic Tag Generation.
- Added German language support.
- Added Japanese language support.
- Resolved an issue that could cause memory corruption and runtime crash.
- Corrected an issue where nested UDT structures within arrays weren't parsed correctly from ‘s7p’ files during Automatic Tag Generation.
- Fixed an issue where validating invalid tag addresses with 16 or more continuous alpha characters could result in a crash of the Runtime. This could occur in two cases: after Auto Tag Generation from a device containing symbolic tags or if a client referenced tag names not defined in the server.
- Fixed an issue where tags of type 'Date' could result in other tag values not being updated. This only occurred with tags that were in the same block as the Date tag.
- Added support for HEXSTRING data types.
- Enhanced Automatic Tag Generation support to include extended (non-ASCII) characters.
- Fixed an issue where an uninitialized buffer could cause a buffer overflow and result in a crash.

This occurred when there were two or more devices under one channel that had tags pointing at the same address, but with a different Byte Order selected. This could result in an incorrect Byte Order for one or all of those tags.
