STEP 7     V5.6 SP1 Upd3      08/07/2019   

PCS7里的Step7更新了，但是之前的step7更新链接里没有 我看文件还是4月份日期 所以再等等

HW Config

·                     The installation of HSPs is now possible using the command line call via the HSP installer. You can find more information in the help on configuring the hardware in topic "Installing HW Updated via the Command Line".

·                     The operation of a DP/FF-Link downstream from an IE/PB-Link V3.1 is now possible.

·                     As of this Hotfix: A configuration in RUN is now once again possible for specific configurations that were downloaded to the CPU with STEP 7 V5.5 SP4 HF9.

NetPro

·                     The output of warnings during compilation in NetPro has been improved.

Report System Error

·                     Generating 'Report System Error' has been improved.

看以上更新内容还是填坑，尤其是5.5 HF8的坑，如果没有遇到可以暂时先不装…… 等一楼的链接更新。

// 八月都过一半了 这个更新和TIA V15.1 update3 还没出来 无奈啊
