Product Description

The F77 compact housing design can be programmed and so adapted to various applications.
You can program limits, output mode, output type, and sound beam width via the programming
button on the sensor or the convenient IO-Link interface. Programming via the IO-Link also
provides the option of setting many other parameters such as filter options, echo suppression,
synchronization settings,...
The IO-Link versions with switching output enable IO-Link communication in accordance with
the IO-Link standard. The F77 versions with analog output can be configured via their IO-Link
interface but are not designed for long-term IO-Link operation.
The advantages of the UC***-F77 series ultrasonic sensors are:
■ Compact housing design
■ Advanced setting options via programming button on the device
■ IO-Link 1.1 interface for service and process data, and for parameterization
■ xcellent immunity to background noise such as compressed air
■ Can be self-synchronized to avoid mutual interference of several adjacently mounted
ultrasonic sensors
■ Programmable echo suppression
■ Also available as sidelooker version with M18 mounting option and higher detection range
What is IO-Link?
IO-Link is a new dimension in the communication of and with sensors. The possibility of making
the intelligence that is already integrated in each and every sensor fully available to users
opens up new possibilities for automation. Using IO-Link brings specific advantages to all
areas of application in the field of factory automation; in service (fault elimination, maintenance,
and device replacement), during commissioning (cloning, identification, configuration, and
localization) or in operation (job changes, continuous parameter monitoring, and online
diagnostics). Reducing the variety of interfaces offers users significant savings potential. This
variety of interfaces often results from having analog sensor inputs and the complex installation
required in this case.
Device description file (IODD)
The sensor parameters are different for each device. These parameters are described in a
standardized format in the device description IODD (IO Device Description). The IODD can be
imported into various engineering tools from different system providers, providing they support
IODD. The sensor can be configured or diagnosed using the appropriate tool.
You can also transform the IODD via the "IODD DTM Configurator" to configure via a tabular
user interface. We recommend "PACTware" software as the user interface in which you can
load the transformed IODD. It is also possible to use equivalent software.
You can find the device description file (IODD) which is necessary for connecting to an IO-Link
system online at www.pepperl-fuchs.com on the product page for the relevant UC***-F77-... .
DT (Device Type anager)
If a sensor is not used long-term in an IO-Link environment, but nevertheless needs to be
configured, this can be done easily via a PC with installed FDT framework application (e.g.,
PACTware) and with the DTM (Device Type Manager, a kind of "device driver") available for the
sensor. Unlike configuration via the IODD, this method provides extended functions and
ensures improved graphic visualization and convenient operation. Functions such as UC***-
F77 series "echo suppression" can only be configured via the relevant DTM.

Sensor Programming via the Programming Button
5 Sensor Programming via the Programming Button
Basic information about programming
In terms of factory settings, the sensor can only be programmed during the first 5 minutes after
switching on. This time is extended during the actual programming process. The option of
programming the sensor is revoked if no programming activities take place for 5 minutes. After
this, programming is no longer possible until the sensor is switched off and on again.
When configuring sensors via the IO-Link, you can use the DTM to adjust the programming
button’s locking logic. This is done in the "Sensor configuration" menu option, "Local controls"
tab.
When actively communicating via the IO-Link interface of the sensor, it is not possible to use
the programming button to program.
The programming activities can be canceled at any time without changing the sensor settings.
To do so, press and hold the programming button for 10 seconds.
Programming via the programming button can take place in the stand-alone mode of a sensor
or also in the synchronized sensor group of several sensors (only for automatic common mode
and multiplex mode). When programming in the synchronized sensor group, there may be a
delay to starting the programming routine, depending on when the sensor in question is next in
line. For the duration of the programming process, the other sensors in the sensor group go into
standby mode (green L D is flashing). Then synchronization mode continues to operate as
normal.
5.1 Programming Switch Points/Limits
Programming Switch Point 1/Near Limit (SP1)
If the object is detected correctly during the programming process, the yellow L D flashes
slowly. If no object is detected, the yellow L D flashes at a higher frequency. A flashing red L D
during or when completing the programming process indicates unreliable object detection. In
this case, correct the alignment of the object during the programming process until the yellow
L D flashes. Only then will the settings be transferred to the sensor memory.
1. Position the object at the site of the required switch point/the required near limit.
2. Press and hold the T programming button for 2 seconds (yellow L D flashes)
3. Briefly press the T programming button (green L D flashes 3 times as confirmation). The
sensor returns to normal operation.
Programming Switch Point 2/Far Limit (SP2)
1. Position the object at the site of the required switch point/required far limit.
2. Press and hold the T programming button for 2 seconds (yellow L D flashes)
3. Press and hold the T programming button for 2 seconds (green L D flashes 3 times as
confirmation). The sensor returns to normal operation.
Note!
Depending on the type of sensor, you can program the switch points for sensors with switching
output and the limits for sensors with analog output. The programming procedures are the
same in both cases and are therefore described in conjunction below.
