The following list shows some examples when IEDs are connected to SYS 600C with
the following Gateway or NCC connections and with Local process database:
• NCC connection with one DNP LAN communication including 84 IEDs resulting
in 1 000 process updates per second sent to one NCC
• NCC connection with two DNP LAN communications including 67 IEDs resulting
in 1 600 process updates per second sent to two NCCs
• NCC connection with one IEC 104 LAN communication including 158 IEDs
resulting in 1 900 process updates per second sent to one NCC
