5.8 INPUTS AND OUTPUTS
On the two-terminal, two channel system (redundant channel), direct outputs 1-1 to 1-8 are send over both chan-
nels simultaneously and are received separately as direct inputs 1-1 to 1-8 at channel 1 and direct inputs 2-1 to 2-8
NOTE
at channel 2. Therefore, to take advantage of redundancy, the respective operands from channel 1 and 2 can be
ORed with FlexLogic™ or mapped separately.

The relay provides eight direct outputs that are conveyed on communications channel 1 (numbered 1-1 through 1-8) and
eight direct outputs that are conveyed on communications channel 2 (numbered 2-1 through 2-8). Each digital point in the
message must be programmed to carry the state of a specific FlexLogic™ operand. The setting above is used to select the
operand which represents a specific function (as selected by the user) to be transmitted.
