Hello everyone,

I am new to programming PLCs and I have been given a S7 315-2 DP  to try out.

The CPU is  6ES7 315-2AF03-0AB0 with firmware V1.2.0 and I am using TIA Portal V13 SP1 connected through the MPI to USB adapter.

I am trying to do my first project but have run in to a problem.

In the hardware only two devices are in the CPU 315-2 DP folder

• 6ES7 315-2AG10-0AB0   V2.6
• 6ES7 315-2AH14-0AB0   V3.0  &  V3.3

but I have an older device 

• 6ES7 315-2AF03-0AB0 V1.2.0

I have compiled an empty test program which gives no errors, but when I download the program to my CPU an error is flagged. The error that shows up in the diagnostic status is the following.

Module exists.

faulty

Differences were found between the loaded configuration and the offline project.

The online and offline module configuration data are different.

After having searched the internet, I haven't found a solution to my problem.

I have the following questions.

Can I create a program and download it to my CPU using one of the newer CPUs included in the hardware without any problems?

Can I update the firmware on my CPU so that it matches the CPUs found in the hardware catalog?

Do I have to update the hardware catalog so that it includes my CPU?

Do I have to install an older version of STEP 7 for example STEP 7 V5.1 and create my program with that?

Yes.

Actual version is Step7 V5.5

I would like to thank you both  ChristophD  and  IBN-Service  for your swift response and taking the time to answer my question. 

kind regards,
