Hi all,

I am currently working on a project upgraded from TIA Portal V17 to V19, where we are using an S110 drive. The original project was developed by another engineer, and I am now tasked with making some parameter changes.

Our engineering team replaced the motor with one that includes a brake, so I need to modify the S110 drive parameters accordingly. I have received the backup configuration from the previous programmer.

On my system, I have STARTER V5.7.0.1 installed. When I open the backup in STARTER, a popup appears stating “Missing software - STEP 7 V5.7 + SP3”.

My questions are:

• Why is STEP 7 V5.7 + SP3 required when I am using TIA Portal V19 and STARTER V5.7?
• Is it necessary to have a STEP 7 license installed to make changes to the drive parameters in this case?
• Can I safely ignore this popup and continue editing the parameters without any issues?

I do not have a STEP 7 license installed on my PC. For your reference, I have attached a screenshot of the popup message.

I would appreciate your guidance and clarification on this matter.

Thank you in advance for your support.
