3.3.9.4
Control bits
As of V1.10
5 control bits SBIT 0 ... 4, can be transmitted via the technology control word 2 (TSW2), bit
10 ... bit 14.
Like digital input signals, these control bits can be controlled by their edge, level, inverted
and non-inverted, linked to any function blocks and/or directly with motion tasks.
See also A.1.2.4 TSW2 - Technology control word 2 (Page 289).
3.3.9.5
Special function blocks
An active system fault can be acknowledged by means of the special "fault
acknowledgement" function block. The acknowledgement is triggered after the input signal
has been active for at least 5 s.
The controller's emergency power mode can be activated by means of the special
"emergency power mode" function block. You can find additional details about the
emergency power mode in the section Emergency power mode.
3.3.9.6
Discrepancy analysis blocks
The discrepancy analysis block "AND0" has four time-monitored inputs, two of which are
negated or inverted. The output signal at Q17 behaves according to the following rules:
● The output signal only becomes active if all inputs were activated synchronously within
the time defined via parameter p4610.
● The output signal becomes inactive as soon as at least one input signal has become
inactive.
● The output signal can only be reactivated after all input signals have been inactive.
As of V1.10: The 2nd Discrepancy analysis block "AND2" reacts like "AND0". The output
signal is available at Q64. The discrepancy time is set with parameter p4611.
3.3.9.7
Basic blocks
The basic function blocks "AND", "OR", "NOT" and "XOR" are provided to be able to map
basic logical combinations.
