5.2 Double command (DC) / Double-point indication (DP)
Range of values:
0 (bit 1 = 0 and bit 0 = 0) - „Not applicable“ for DP,
not permissible for DC
1 (bit 1 = 0 and bit 0 = 1) - OFF
2 (bit 1 = 1 and bit 0 = 0) - ON
3 (bit 1 = 1 and bit 0 = 1) - Error status/Intermediate position for DP,
not permissible for DC
Note
• „Not applicable“: double-point indication is not configured (not
assigned to a binary input).
• The value „11“ ist transmitted for intermediate position „00“ too.
