    Hi Folks, Was wondering if anyone has had experience with an S5 110? I am trying to upgrade this to an S7 which seems quite an easy task. I have a printout of the 110 program so just need to type this into S7. This is fine although heres my problem.... the 110 has 3 timer modules fitted and I'm unsure of the priciple of operation. The addressing in the program seems to indicate an input and an output is assigned but I dont really undertsand this. Can anyone help? I've trawled the net but not had much success. Thanks in advance

    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

    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

    Hello all, I was wondering if someone could maybe help me. I'm trying to convert the following code into LAD or FBD. I understand that sometimes due to complexity of STL that this would not be possible but the code I have looks not too bad. Appreciate any help. A I 1.0 AN M 2.3 A I 4.3 O M 0.0 AN I 0.3 AN M 0.4 = M 0.0 and A I 0.1 O M 0.1 A M 0.0 = M 0.1
