4.3.9.6 Discrepancy analysis blocksThe discrepancy analysis block "AND0" has four time-monitored inputs, two of which arenegated 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 thetime 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 second discrepancy analysis block "AND2" behaves like "AND0". The outputsignal is available at Q64. The discrepancy time is set with parameter p4611.As of V1.12: A violation of the discrepancy time is indicated for "AND0" and for "AND2" in thefollowing ways:• TZW2 – bits 6 (AND0) and 7 (AND2) - see section TZW2 - technology status word 2(Page 325)• As "a" on the operating status display - see section Status display (Page 303)4.3.9.7 Basic blocksThe basic function blocks "AND", "OR", "NOT" and "XOR" are provided to be able to map basiclogical combinations.4.3.9.8 Frequency analysis blocksAn input signal can be analyzed for specific frequencies and duty factors via the "FRQ" frequencyblocks. Two identical frequency analysis blocks are available, capable of detecting frequenciesof 1 Hz and 0.5 Hz with a duty factor of 20 %.The detection criteria and the valid tolerances are described in detail in the following figure.SIDOOR functions4.3 Extended functionsATD4xxW for industrial applicationsSystem Manual, 06/2022, A5E51901827B AA 99
