I'm having a problem with the source code provided when the equipment was delivered.
We need to modify the program as part of a diversity increase in our process and it seems that the project was created using an older version of Step 7 (probably 5.4) and now we have Step 7 5.5 in our machines. This machine is based in a MP277 HMI using WinAC as the PLC and the HMI it self.
For some reason when I try to open the project (after I have updated the hardware catalog) it says that the HW-Update is an "older version or not fully installed" and you can see in the anexed picture. I have thoroughly followed the procedure to update it (downloaded and then installed the download files).
I tried updating it several times and it didn't work. I starting to think that I'll have to install Step 7 5.4 to be able to open it. At first I had a problem with WinCC flexible now I have installed all of the requires programs and updated the product catalog and it still won't open.
the reason I know it's not the program is that we have a Siemens PG and all the programs (Step 7 5.x and WinCC Flexible) are installed and it's running ok. I might check the real version of the programs running in this PG so I can compare to what I got here.
But this PG it's not avaliable for us engineers it's stricltly for the maintenance crew and even though I can use it once in a while, for develepment and modifications that don't involve maintenance I will have to jeaopardize the avaliability of this machine in case of a problem, and you might know well that if this PG stops working they will probably say I did something to it. And It's not cool to mess with a U$ 10,000 equipment.
Thanks in advance for any help given.
