In a redundant configuration, a D400 can be connected to eight D.20 RIOs, with each
redundant pair of D.20 RIOs providing communication with up to 30 peripherals.
Features of the D.20 RIO include:
•
Dual D.20 link channels support looped peripheral systems
•
Integration with the D400 Substation Gateway
•
Manages peripheral code and configuration downloads
•
LEDs for device power and status, D.20 TX and RX, and Ethernet link activity and
connect speed
•
10/100BaseT interface for D.20 protocol communication with the D400 Substation
Gateway
•
Optional low and high voltage power supply modules
•
Inserts power on the D.20 interface cable
•
1U 19 inch rack, DIN rail, or panel mounting options
•
All connectors are mechanically secured
•
Supports 802.3p and 802.3Q (VLAN) to ensure D.20 data receives higher priority
•
1 ms accuracy using SNTP time sync
1 ms accuracy recorded for 99.6% of the total D.20 RIO points. See "Product
specifications" on page 17 for more details.
A D.20 network enables GE Digital Energy devices to connect to D20-series peripherals. It
uses an HDLC protocol to acquire data from and to send commands to the peripheral
devices. The D.20 network supports the following peripheral modules:
•
D20 A - Analog input peripheral
•
D20 S - Digital (status) input peripheral
•
D20 K - Digital (control) output peripheral
•
D20 C - Combo peripheral available in three configurations (C0/C1/C2) providing
combinations of digital inputs (C0/C1/C2), digital outputs (C0/C1/C2), analog inputs
(C1/C2) and analog outputs (C2)
