Does any one have experience with or ever applied the function external machine option before. I am aware of its basic purpose and also know about AsSafety library and FBs like ‘’ safeDownloadData’’ but i still don’t understand how to make my safety application flexible based on the “External Machine options”. For example, i have “machine A” with 3 axes X,Y and Z with safeMotion application and would like to have axis Z as optional because for “Machine B” i only have axes X and Y. In safedesginer i can see this option under the SafeLOGIC X20SL8101 as shown here , but i just don’t know how to go about it. By the way we are not using mappSafety for our application. I couldn’t find a good example or material in Help regarding this. Any help or guidance is appreciated.
