controllers to the internet
When Saia PCD controllers are connected directly to the internet, they are also
a potential target of cyber attacks. For secure operation, appropriate protective
measures must always be taken.
PCD controllers include simple, built-in protection features. However, secure op-
eration on the internet is only ensured if external routers are used with a firewall
and encrypted VPN connections.
