OP7 Program File

[Guest Mister Spark]

Hi all, I'm currently trying to download a program to a new Simatic OP7. I have received a file with the extension .arh from a suplier, but protool does not recognise this exstension so the file can't be transfered to the OP7. It was my understanding that protool and OP7 only work with .pdb files. Am I right in assuming this or is the .arh extension also supported? Cheers Mitch

Can it be that the .arh file is actually some kind of compressed format. In the past I have seen som .arj files, but not .arh Contact the suplier and ask them for the .pdb file.

use prosave 7.1 to download that file.
