Hello, we have an industrial control system and we want it to be isolated and secured, and not connected to a computer network
but recently we should connect the rs422 port of a panel to a network to send some infomation
the panel is controlled by some controllers and is connected to the control network computers...
it must be something like sending information to printer, and its jut send not receive
but I dont know if we can limmit rs422 to one direction sending, should we use a firewalll and where?
and is it possible viruses and worms penetrate to the control system via that port and controllers...
