Hi I'm trying to emulate sending a message from my cpu on telegram.

I'm using the example shown (i have only plc)

HERE

i am working on s7 1200 cpu 1211c AC DC RLY firmware 4.4 TIA 16v.

when I turn the send Message to TRUE

the Status shows me 16#7002 and Busy TRUE for 10 seconds then becomes 16#8701 and Error TRUE.

i am using my router connection 192.168.1.1

assigned same network ip to plc 192.168.1.80

what should i put to the dns server?

I entered my phone company's dns

I tried to enter my ip, but it doesn't work.

as certified I entered

"Go DADDY ROOT Certificate Authority G2".

I searched on the net and here on the forum but I didn't find the solution.

i hope someone can help me.

Thank you

ps

I noticed that in statSubfunctionStatus I have the value 16#8601

i made some changes

in the plc i activated the subnet and i assigned my ip to the dns

now when sendMesage is TRUE

status becomes 16#7002

busy becomes TRUE

after 10 seconds they return to the initial state

but checking the program block

I noticed that statSubfunctionStatus

from 16#0000 at the end of 10 seconds it becomes 16#8604
