do03 flag operator mode [2] = 3 “AND”
Definition flag 3 (I3 set => Bit 2 ru18 set):
do01 flag operand A [3] = 18 “dig. input state (ru18)”
do02 flag operand B [3] = 28 “level 2 (do06)”
do06 flag level 2 [3] = 4
do03 flag operator mode [3] = 3 “AND”
Linking the flags:
do20 select flag O1 = 7 “F1 + F2 + F3“
do19 AND operation for output = 1 (selected flags for O1 are AND linked)
Output O1 is set only if the condition F1 (I1 is set) and F2 (I2 is set) and F3 (I3 is set) is
fulfilled.
Inversion of the digital output state
The terminal state can be inverted via object do11 dig. output logic. The state after the
inversion can be read out via the object ru18 dig. input state.
Only outputs of the control board can be inverted via this parameter. The outputs of the
safety module cannot be influenced by the control board.
Overcurrent of the digital outputs
All digital outputs are protected against overload by hardware. When this protection is ac-
tivated, a separate error is generated for each output.
