Hi, I didn't check voltage level but I suppose that is about 0-5V. The second points, I write this program in OB1 cycle block. The first, OB1 call PB 94 and then, in PB94 calls PB 194 where I make changes. And in PB194 I call FB15. I have three nesting. In FB block I didn't use formal operand, only direct addressing. Best regards.

Hi luciferC4, You need to remove the eprom, before you can change your program. First of all you need to load the s5 program to a file (all blocks "B") to make sure you don't loose any machine data. Then you switch off the plc and remove the eprom. After power on you will have to reload the program to plc and check if it works properly again. After this all is done you are free to start changing and testing your program ... Good luck |

Hello Simaticus, I must ask you something. Still I haven't done changes (because machine had to work all time) in plc program. But before that can you explane what do you mean under your advice:First of all you need to load the s5 program to a file (all blocks "B") to make sure you don't loose any machine data! I have original version of program and for safety, I did upload from plc program and made one copy where I made my changes and that version I'll download in plc. BR.
