Hey guys. I have a very basic question. I'll explain the reason for the question first.

I have a good amount of experience with Allen-Bradley SLC5/04, Logix 5000, and their HMI software PanelBuilder and RSView. I have not ever before used Simatic software.

In other words, I have a very strong working working knowledge of programming and panel design, but no experience with Simatic.

I have a panel with a Simatic S7-1200 PLC and a small Simatic Touch HMI. The panel is stand-alone and does not have any external SCADA or other network connections.

This panel was built by a company who is not able to provide a competent technician to modify some timers and simple logic problems.

Here's the question. What do I need to do, with Step7 TIA Portal V12, to connect and read-back the existing program from the PLC and HMI?

As I said, this is a VERY basic question and I apologize for being such a NOOB. Smile

I have watched tutorials on Simatic Step7 from Siemens, but they don't go into the details of read-back of an existing program.

There is a possibility of getting the source code from the autentic panel builder, however I will not be sure it is correct and matched to what's in the unit. So I would want to read-back and save what's there now.

If anyone has a video of this, or any step-by-step instructions it would be very much appreciated.

Sincerely,
David

I'm going to hopefully go back to the location of the panel today or tomorrow to get all information. It's a Simatic Touch but as for the tip number I didn't record that.

I didn't get all the info because at first I thought someone else was going to fix it. Smile

Ok, I went back to the station with this panel and tried to connect Step 7 TIA Portal to the system.

I was able to see and connect to the PLC and HMI, but the PLC program blocks all had a red X and the system told me I needed Step 7 V.11, instead of V.12. So I am installing V.11 and will go back tomorrow.

The HMI would not allow any online actions, and showed as a "non programmable" network module.

I'm learning quick that this software is very picky about versions. I probably need to install every version up to the latest.

The HMI is a 10 inch version 100 - PN. I am frustrated because I don't have access to the notes where I wrote down the actual number.

Just an update. I was not able to read-back the programs from the panel. I was however, able to get the autentic program source from the panel builder so I have all files and documents.
