Hi, a newbie to siemens step-7 who has no training at all.
Currently have a few questions regrading programming,
1) what is the step-7 equivilent of rslogic500's OSR,first scan pulse,? how do i add it to my rung?
2)how do i change the timers/counter's timebase? its stated in the help file as a 16bit word but i do not know how to change/edit that value.
3) how do i assess the timer's done status as opposed to rslogic500 timer/dn and timer/en bit??
many thanks in adv!!!
