inst_tech Posted February 28, 2008 Report Posted February 28, 2008 Hi all, I'm trying to convert the following code into FBD but again having problems. I've tried various combinations through PLC Sim but the logic just doesnt seem to match. Heres what I'm trying to convert:- A M0.2 AN M1.0 L S5T#1M SD T1 A T1 AN M1.0 AN M2.1 A I4.2 O M0.3 A M0.0 = M0.3 Thanks for any pointers. Regards
Preet Posted February 28, 2008 Report Posted February 28, 2008 SD T1 is which type of timer ? or if it is something else.Plz clarify. Preet
inst_tech Posted February 28, 2008 Author Report Posted February 28, 2008 SD is an On Delay Timer Regards
inst_tech Posted February 28, 2008 Author Report Posted February 28, 2008 Hi, Thanks for your help although having run it through PLC sim I'm not sure its quite right. In the original code M0.3 will not come on unless M0.0 is high (this seems correct as M0.0 is the "Automatic On" flag. When testing your code M0.3 will come without M0.0 being high. I tried this but it also didnt work:- A ( A M0.2 AN M1.0 L S5T#1M SD T1 NOP 0 NOP 0 NOP 0 A T 1 ) A( O I4.2 O M0.3 ) AN M 2.1 A M0.0 = M0.3 Thanks for any further help. Regards
inst_tech Posted March 1, 2008 Author Report Posted March 1, 2008 Thanks, thats great. I can now see how the code converts which will allow me to try the rest of the program. Wish me luck............ i'll need it! Regards
