Signal

Source Note

Name Type DIS DIS format CFG List

FCNT1−CLKUP d C1104/1 bin C1102/1 2 LOW−HIGH edge = counts up by 1

FCNT1−CLKDWN d C1104/2 bin C1102/2 2 LOW−HIGH edge = counts down by 1

FCNT1−LD−VAL a C1103/1 dec C1101/1 1 Starting value

FCNT1−LOAD d C1104/3 bin C1102/3 2 · HIGH = Accept starting value

· The input has the highest priority

FCNT1−CMP−VAL a C1103/2 dec C1101/2 1 Comparison value

FCNT1−OUT a − − − − Counter limited to ±199.99 % (¢ ±32767)

FCNT1−EQUAL d − − − − HIGH = comparison value reached

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.
