how to upload project from cpu1215c v4.3 to tia v14?

[numone 0]

we have a machine with cpu1215c 6ES7215-1HG40-0XB0 firmware v4.3 and the cpu has been programmed with tia portal v14 sp1. we do not have the source of project and we just want to upload it.

now when we want to upload the project from cpu to tia portal 14 it says that the firmware of online cpu is 4.3 and the offline is 4.2 and you cannot upload!!

how is it possible?

how we can upload project when v14 does not have firmware 4.3?!!

if we use tia portal 16 it says that the the online cpu has been programmed with tia 14 and you cannot upload it to tia 16!!

 

what has siemens thought for this endless loop?

Sounds like there may be an upgrade to v14 that you have not installed.

Like Crossbow said, there may be a service pack for v14 that you need to install. Contact Siemens Tech Support about that.

If that's not it...good luck....

At a previous location, I encountered a similar firmware issue with Sinamics drives in Simatic Manager. Because we had a few S7-315T processors, we had to install S7 Technology instead of Starter. If you uploaded out of a PLC, the software would just assign the newest firmware version it supports to any Sinamics objects, regardless of what they were in the field. It then wouldn't connect to the drives until you flashed the drives' firmware to the newer version. The only way we were able to successfully connect to those drives was to have a virtual machine with an older version of S7-Technology installed and create an empty project with whatever version of the firmware was actually in the drive, then upload. We then had to maintain two Simatic Manager projects for that machine with a note to open the drive project with a particular virtual machine only or it would convert it and you couldn't go online any more. By the time I left, I was maintaining 5 virtual machines each on 6 different laptops just for the different versions of S7-Tech and Portal we had to support. The answer from Siemens tech support was "just upgrade everything to the latest and don't make any mistakes". When we asked for Siemens to help us reconcile some of that, they said they could help us, but it would cost a lot and theyweren't responsible for any extra downtime for when things didn't work out perfectly.

By the way, I experimented with another virtual machine with Starter instead of S7-Tech with similar weird results. We had 3 machines with "T" processors that were all 3 from the same builder and were each at a different version of S7-Technology. We briefly had a 4th machine that was at a 4th version. Sadly, efforts to have them come in the same were fruitless.

Sigh...

Again, good luck...
