Hello
I have 1214C DC/DC/DC CPU which I can't communicate with it through pc. When I'm Trying to search the cpu in tia portal I can't find it.
The plc was working properly but suddenly it's status lamps goes as following
Run/stop flahes green and yellow
Error lamp is always red
Maint lamp flashes yellow
Also when I connect ethernet cable between pc and plc
Link lamp always green
RX/TX always off
Any help will be appreciated.
