Hello TommyM you certainly can read out the Safety Signature from your standard program and then use it for comparison,display on a HMI etc. The Safety Signature is available asTypeDWORD in the F_GLOBDB and you need tosymbolically access it as: "F_GLOBDB".F_PROG_SIG Other Safety program related variables you might be interested in are (see also chapter 7.1 of SIMATIC Industrial Software S7 Distributed Safety - configuring and programming manualfor more on this): "F_GLOBDB".MODE(Type BOOL:1=Deactivated Safety mode) "F_GLOBDB".ERROR (Type BOOL:1=Error occured inexecutionof the Safety program) "F_GLOBDB".F_PROG_DAT (Type DATE_AND_TIME: Date and time of last compilation) Note that you'll also get these variables listed if you do a printout of your SafetyProgram (see also attached example pic). I hope this helps |
