The usage of the sld tool is simplified:

  • Starting with release May 2024, the SIMATIC app file is built in a generic form valid for all types of the SIMATIC S7-1500 PLC family.
    So, it is only required to build for the target "1500" and the sld tool is performing the final adaption to the specific PLC while downloading. The target plcsim can be removed from apax.yml to avoid building the ST code twice. If such a case occurs, you will receive a warning from apax build.
    As a result, the --input option of the tool is now optional and defaults to the ./bin/1500 folder.

    Building a library in AX is not changed at all and will continue to use the target "1500".

  • On target side, the options --target, --username and --certificate can be omitted, if you define the variables myPLC_IPADDRESS, myPLC_USERNAME and myPLC_CERT in apax.yml.
    Details are described in the section connection parameters.

  • This version of sld supports only SIMATIC app files build with stc 6.x or 7.x, but not future versions of stc.

  • The sld tool is prepared for the end-of-support date of DotNet 6 in November 2024. Details can be read here

  • Describe sld functionality more detailed in the documentation.
