Since you are able to adjust the local time with your plc, you are done once you do. The system time will be updated when you update the local time as you saw. No need to update the system time. With those of us who are not fortunate enough to be able to write the local time and have the plc automatically set the system time for us, my prior post might help them. For you, you have it easy and I am thankful you posted your results. Is this useful or am I still not clear what your real question is? If you want Siemens to change how they have been handling sytem and localized time, you need to submit a Support Request wth a very good reason. I know Siemens has posted many FAQs on doing the very thing that seems to be causing you so much frustration. So they do listen. |

Thanks for reply, huggy, but it seems that I am not able to underline perhaps the main point... Even if I am able to write (WR_LOC_T) the Local time, two problems are present: 1) WR_LOC_T has a second input parameter, the DST. You have to put TRUE if the date ur going to set is in DST or vice-versa 2) Automatic DST setting seems to not affect the local time but only the System Time (it's a nonsense but I spend many time in controlling this). I put Local time settings at 5 seconds before the DST time change (that I have set in configuration before), I look at the Local time and System time together... You see system time increasing of 1 hour and local time proceeding normally. Basically, it could be a great thing to work with system time only, using the WR_SYS_T. I will do some tests on this because if system time works better than it could be possible to forget the Local time... I'll post results sooner
Well, before doing a such kind of thing I'd like to know if I am really missing something of big on this argument... |
