Could say me what is wrong ?

[spadekevin]

Hello,

I updated my drivers and I use Simantic S7IsoTcp driver.

I communicate by ethernet through a Switch. I'm trying just to display an input and an output tags and a memory input tag from the PLC. It seems there are no communication between the HMI and the PLC because I have this message "comm err station 0".

From my computer, I can ping the HMI and the PLC with answers.
When I analyse the frames on Wireshark, I see "who has 172.17.2.10? Tell 172.17.2.39" (172.17.2.10 is the PLC ip address and 172.17.2.39 the HMI ip address). But there are no answer from the PLC.

I add images of my configuration.
Could say me what is wrong ?
Please help

I didn't find the right solution from the internet.
