You can find oscat library for S7 here: http://www.oscat.de/component/jdownloads/summary/2-oscat-basic/8-oscat-basic-332-s7.html To be able to process the archived file you need STEP 7 professional (S7-SCL included).I copied 2 function blocks that are PWM in signal generation section.They work for S7-300/400 while for S7-1200 you need to customize.If this is difficult to convert , I can provide simple algorithm to make PWM in software In real CPUs all OB30 -->OB39 are not used as cyclic iterrupts, as my favorite Giant CPU (S7-417), supports only OB30-->OB38 but other supports limited numbers of OB3X.
