Encoder Redundancy
The DTA3050 enables encoder redundancy for Adtec's line of encoders. Three types of redundancy are supported:
1:1 •
N + 1 •
N + 2 •
1:1 Encoder Redundancy
The most basic form of redundancy is 1:1. Input-port pairs on the DTA-3050 support redundancy. The configuration is set as
a Boolean for 1:1 redundancy on any of the ten input ports. The port pairs are: 1 and 2, 3 and 4, 5 and 6, 7 and 8, and 9 and
10. If either port in a pairing group is set to be redundant, then both ports are put in redundant mode. Once a port has been
defined as redundant, the paired port will become the identical configuration of the port set to redundant.
Redundancy is determined monitoring the status of sync and reception of table information. In the event the primary port is no
longer receiving table information from the encoder, the port is disabled and the secondary is placed on line.
