The D400 can support up to eight network connections to host and network clients,
including:
•
SCADA master station
•
Substation LAN
•
Enterprise network (Corporate wide area network). The following networking
connections are supported:
–
Ethernet (Twisted pair or Fiber optic)
–
COM2 (for dial-up)
The D400 accepts a time synchronization input (IRIG-B format) from GPS receivers that can
be subsequently distributed to connected devices.
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.
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.
The D400 provides a series of I/O adapter cards for connecting cables and wiring from
substation devices and network interfaces. All physical connections are made to easily
accessible connectors on the rear panel of the D400.
