Double command
Double commands are process outputs which indicate 4 process states at 2 outputs: 2 defined (for example
ON/OFF) and 2 undefined states (for example intermediate positions)
Double-point indication
Double-point indications are items of process information which indicate 4 process states at 2 inputs: 2 defined
(for example ON/OFF) and 2 undefined states (for example intermediate positions).
DP
→ Double-point indication
DP_I
→ Double point indication, intermediate position 00
