Counter Module 750-404 4

:$*2⇓,2⇓6<67(0

An example:

The counter is set with “Set Counter” to the value 0x0000.0000

- 0X1X.XXXX, 0x00, 0x00, 0x00, 0x00 are carried over as output value

(carry over the control-byte and the new counter position),

-wait until the input value is 0X1X.XXXX, 0x00, 0x00, 0x00, 0x00

(the status-byte shows the loading feedback) ,

-carry over 0x00, 0x00, 0x00, 0x00, 0x00 as output value (release counter).

Wait for the first and further counting pulse

-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x00 (no counting pulse received)

-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x01 (1 counting pulse received)

-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x02 (2 counting pulses received)

-.................

-the input value is XX00.XXXX, 0xFF, 0xFF, 0xFF, 0xFF (maximum counting position

is reached)

-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x00 (a further counting pulse

causes an overflow)

-the input value is XX00.XXXX, 0x00, 0x00, 0x00 0x01, (a further counting pulse is

received)

Notes: 0x23 is a value in hexadecimal form

0101.1001 is a value in binary form

“X” is used if the value at this position is without any significance.
