A rising edge at SetCnt will set the counter to the 32 bit value that is written
by the controller into the process output data.

Workpiece measurement

If the workpiece measurement is
enabled, it is read via CB1.3 and
CB1.4 and saved in two latch values.

enabled

CB1.0

EnLatchC

1

bin

The rising edge of the zero input (

input C [

}

19]

) is active. The

counter value is stored in the latch register at the first external latch
impulse after the EnLatchC bit becomes true. The subsequent pulses
do not have any effect on the latch register. (see note below)

Note

EnLatchC or EnLatchRise and EnLatchFall?

If bit CB1.0 (EnLatchC) is set, bit CB1.3 (EnLatchRise) and bit CB1.4 (EnLatchFall) must
not be set, otherwise you cannot know which event has caused a counter value to be
stored in the latch.

Status byte 1 in process data mode

The status byte 1 (SB1) is located in the input image, and is transmitted from terminal to the controller.

ValLatchC

bin

A zero-point latch has occurred: a rising edge at the zero input (

input

C [

}

19]

) has caused the current counter value to be stored in the

latch register as a reference mark.
Subsequent pulses do not have any effect on the latch register. To
reactivate the

gate/latch input [

}

19]

you must:

• set bit 0 (EnLatchC) in the control byte to 0

bin

.

• wait until this change has been acknowledged by resetting bit 0

(ValLatchC) in the status byte.

• set bit 0 (EnLatchC) in the control byte to 1

bin

again.
