Hello,

i m trying to upload the programm from our ET200S IM151-8 PN/DP CPU <151-8AB01-0AB0> using TIA PORTAL v13 SP1. Both programms are made with TIA PORTAL V13, so they told me.

i use the ping instruction to see the device and i take a respond. However, when i m trying to upload i take the message that no accesible nodes were found.

I would be greatefull if someone could give me an advice

Hi,

my customer had the same behaviour because virusscanner was active.

Do you know this entry:

What options are available in STEP 7 (TIA Portal) for uploading when the project in the CPU has been created with a different version?

->Please check Key "S/O/N"

Regards,

Towome

Thank you for your replays, finaly i found that the antivirus software was the problem for the problem

Perhaps you must enable TIA communication in Firewall - Settings.
