• Gate function
The gate function can be coupled to one of the 6 inputs on the device. If the
gate function is selected, the counter counts.
If the gate function is not selected, the current counter reading remains
unchanged ("frozen").
• Latch function
The latch function can be coupled to one of the 6 inputs on the device.
If the latch input is selected, then the current counter reading is saved. The
saved value can be displayed in the process image by means of a
corresponding command.
The latch function can be locked or unlocked by means of the process image
(control byte).
• Preset function
The preset function can be coupled to one of the 6 inputs on the device.
If the preset input is selected, the current counter reading is set to a
previously-defined preset value. This function is used, for example, to detect
the C track of the incremental encoders and set the counter value to zero.
The preset function can be locked or unlocked by means of the process
image (control byte).
• Cam function
You can use the cam function to set one of the device outputs when the
current counter reading is in a predefined value range.
Up to 4 cams can be defined for each counter channel. The lower and upper
limiting values and the output channel to be used can be parameterized for
each cam.
The encoder supply for the counter channels can be switched between 5 V and
24 V.
The positive switching digital inputs have a characteristic in accordance with
IEC61131-2, Type 3. They have extensive parameterization options such as filter
times or signal inversion.
The positive switching outputs are designed for 0.1 A (max. 0.2 A) and short
circuit/overload protected. Extensive parameterization options are also available
for the outputs, such as signal inversion, substitute value strategy or restart
behavior.
The properties (e.g. filter times) of all signal channels of the module can be
parameterized independently: depending on fieldbus, via the device description
file (e.g. GSD, GSDML, etc.) of a fieldbus or independent of the fieldbus, via an
FDT/DTM frame application such as WAGOframe.
