Hi, I have a fairly easy assignment for a school project that has the following components: -1 impuls start switch -1 impuls stop switch -2 El-motors When you push start one motor is suppose to run. Then you push stop and it stops. The next time you start the other should run. Only one motor shoud run at the time. I solved this using a KEEP function in ladder logic. But I want to be abel to do the same thing in structured text. So my problem is that I cant fint anything to replace the KEEP function. Any help would be much appriciated.
