Hi guys
I have an existing program on a tia 1500 plc which has an IP address of 172.16.23.### which is ok and a gateway of 172.16.22.01
But our OEM can not see the machine when they use vpn?? They can see our older machines on s7 -300 (classic ) what my question is in tia there is a setting called online access which has an IP address as 169.***.***.*** what is the online access used for and does it have to have the gateway ip??
Thanks stu
