Function
l C1100 = 1
– If | counter content | ³ | FCNT1−CMP−VAL | (comparison value), FCNT1−EQUAL is set = HIGH
for 1 ms. Afterwards the counter is reset to the starting value (FCNT1−LD−VAL).
) Note!
If the signal is to be available longer, e. g. for a query of the output via a PLC, you
can prolong the signal via the TRANS function block.
l C1100 = 2
– If | counter content | ³ | FCNT1−CMP−VAL | (comparison value), the counter is stopped.
– Via FCNT1−LOAD = HIGH, the counter is reset to the starting value (FCNT1−LD−VAL).
l C1100 = 3
– If | counter content| = | FCNT1−CMP−VAL | (comparison value), the counter is stopped.
– Via FCNT1−LOAD = HIGH, the counter is reset to the starting value (FCNT1−LD−VAL).
– FCNT1−OUT is limited to 32767 for counting upwards and to −32767 for counting
downwards.
