Nene Posts: 35 Rating: (0)	Hi, We have two WinCC V 6.0 SP4 systems and a new SCADA in the way. As we are planning to integrate all SCADAS in one, we don't know if it is better to use V 6.2 in the new one or not. Can we simply use the V 6.2 .PDL files in V 6.0 SP4 or must we update our 6.0 in order to do so? We may not upgrade our 6.0 systems right away, in the meantime are there compability issues regarding exporting TAGs,Tag logging,alarm logging, and Graphs from6.2 to 6.0 ?? Thanks in advance, Nene

I am pretty sure of that, unless if somehow you could save the changes to the project in WINCC6.2 to a previous version,of which i have not come across a thing to the likes of that. good luck.

You may open the screens, but functionallity is not guaranteed by Siemens. I've tried changing a project in v6.0 SP4 and opening it in v6.0 SP3. The screens did open, but some control objects, which had been updated in the service pack's release didn't work at all. And deleting those screens and doing the engineering in SP3 didn't make the project work again... so in the end, once I had changed the project in a newer version, it couldn't work again in a previous one, even when I deleted and re-created everything I had changed. It's recommended that all stations run the same version of WinCC. Best regards, Danielle

All versions of wincc are not full compatible when downgrading but with v6.2 to 6.0 you will have a big problem because the SQL have a diferent version (now is V2005). This version have some specific controls and you cannot use it on lower versions.

Danielle Posts: 1275 Rating: (123)	Hi, If you do engineering in v6.0 SP3 and run the project under SP4 it may work, but the correct procedure is to migrate it when using in newer versions. If you edit in the newer version, as I said, even in v6.0 some controls, or even more, may not work. From SP4 to SP3 I know the alarm controls and, if I'm not mistaken, trend controls as well, do not work at all... The advice is to always use the same version for all stations, so you'll have no problems. If you have SP3, you can get the upgrade to SP4 for free. If you have v6.0 and v6.2, the best procedure is to purchase an upgrade to v6.2. As I said, you can get unexpected and undocumented errors by engineering in different versions... and since this isn't supported by Siemens, you could end up simply losing all the engineering you made... Best regards, Danielle
