Hello guys, I am trying to force a flag (M memory) of a S5 cpu( 115U CPU 943B 6ES5-943-7UB21) and I keep getiing this message "Function not permitted" where it is supposed to be "End of force fct.". I never forced a variable in S5, so I might be missing something... but I already read this manual (Display) many times and follow exacly as it shows and it just wont work. What I do is: add variable FY 190 change format to KM press F6 (Activate) once it displays the values I press ESC I replace the bits I want to change ( to 0 or 1 ) then when I press F6 (Activate) "Function not permitted" comes up I cant even find this error for S5 force variables when searching in the web, it is very frustating... Hope some of you guys can help me. Thanks in advance, J.Noguchi Attachment6ES5_998-0MA24.pdf (717 Downloads) |

Hello, I'm French so please excuse my English mistake You can go on 3 page to see some variable. The better one is the one you =can access with Shift + F8. The one with shift + F5 is to force the output, and the one with Shift + F7 is only status, no force. Please not that on Siemens, is your software write your data (here FY190), before you use the value you force, if like if you do nothing. I can't see the mene where you are (I don't have any S5 at this time), it will be better if you take a screen shot or a photo. JD ORAZI S5, S7 expert.(I work from 1989 with Siemens PLC). |
