including:
• SCADA master station
• Substation LAN
• Enterprise network (Corporate wide area network). The following networking
connections are supported:

A substation computer can be set up with the D400 through the USB KVM connections to
access the local HMI.
Optionally, a portable PC can be connected to the front Ethernet port to access the HMI.
Local maintenance
A local PC can be directly connected to the D400 through the front serial communications
port to perform system maintenance using the D400 System Utilities.
