Structure
A FlexChain system comprises a host and a number of guests (sensors). As shown in
the image below, the system components are connected sequentially (bus topology). A
system comprises a host and at least one guest. Up to 60 guests in total can be con‐
nected to a host.
Function
The FlexChain system operates similarly to a light grid. That is, each individual channel
in the system is processed sequentially. This principle means that only one channel at a
time is active. Consequently, there is no possibility of mutual interference within a sys‐
tem, and the guests can be installed arbitrarily close to one another without any inter‐
ference occurring. Due to this sequential processing, the scan time and the response
time of the system depend on the number of connected guests. The total times are
short, however, because the processing interval between two channels is in the µs
range (see also the technical data).

NOTE
Layout of data cables
■
Use shielded data cables with twisted-pair wires.
■
Implement the shielding design correctly and completely.
■
To avoid interference, e.g., from switching power supplies, motors, clocked drives,
and contactors, always use cables and layouts that are suitable for EMC.
■
Do not lay cables over long distances in parallel with voltage supply cables and
motor cables in cable channels.
The IP enclosure rating for the device is only achieved under the following conditions:
■
The cables plugged into the connections are screwed tight.
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!
5.2 Schematic arrangement
The first guest is connected to the host using the pigtail. It can be connected to either
port A or port B. Up to 30 sensors in total can be connected per port.
All guests have an M8 4-pin male connector and an M8 4-pin female connector (pig‐
tail). The pigtail can always be connected to the male connector of the next guest.
The bus terminator must be connected at the end of the system. This is included in the
scope of delivery of the FlexChain host.
With regard to the arrangement of the guests on Port A and Port B, there is only one
restriction for sender and receiver sensors: the sender and the associated receiver
must not be connected to the same port.
If the pigtail cable is insufficiently long, it can be extended using an M8 4-pin cable.
Ensure that the total cable length of the system does not exceed 40 m when doing so.

7 Operation
7.1 Configuration via SOPAS ET
To configure the system via SOPAS you will need the SOPAS software, the SOPAS Device
Description (SDD), and a USB connection.
NOTE
The USB interface is intended only for configuring the device and must be unplugged
during operation.
The SOPAS screen for FlexChain is divided into a number of tabs (orange). Every tab
provides a specific set of parameterization functions. You can easily jump back and for‐
ward between the tabs.
7.1.1 Home
20
The Home tab does not contain any settings. The purpose of this tab is to provide you
with information and status details for the connected FlexChain system.
The Home tab is divided into three areas.
The area on the left (red) shows information about the current status of the system.
This includes, for example, the status of the switching input and switching output pins,
the system status, the teach-in status, etc.
The middle area (green) provides a live display of the channel status. This area shows
which channel is blocked or not blocked by an object. If there is something wrong with a
sensor, this is also indicated directly in this display.
The area on the right (blue) lists the technical values and settings. Details such as the
response time and the number of connected guests are shown here. Furthermore, you
can select a specific guest in the green area by clicking on it. The information for the
selected guest then appears in the “Guest Information” area on the right hand side.

Subject to change without notice
7.1.2 Teach & Positioning
The Teach & Positioning tab can be used to teach in the switching threshold of individ‐
ual guests or all guests at once. The guest position can also be set automatically (auto‐
mated position assignment) or changed manually.
OPERATION 7
Automated positioning
The “Automated position assignment” method is used to automatically assigned a posi‐
tion to every guest in the FlexChain system. Positions are assigned based on the follow‐
ing rules:
1 The first position is the first guest connected to port A. Further positions are then
assigned in increasing numerical order for the guests hanging off port A.
2 All guests on port B are then numbered according to the same principle as in step
1.
3 Sender/receiver sensors are always jointly assigned a position. The receiver
serves as the reference during positioning.
The transmitted process data word also varies according to the position of the guest.
For example, the first channel of the guest at position 1 is represented by the first bit in
the process data word. This means that the sequence within the process data word
depends directly on the guest positions.
Note when changing the number of guests: if a guest is removed or a new guest con‐
nected, this guest is not taken into consideration when using the “Automated position
assignment” positioning method. You need to either use the “Confirm chain change”
method beforehand, or perform the “Auto assign” method (see below).
Manual positioning
The position of each guest can be individually configured via the serial interface and/or
via SOPAS. This option was implemented because the automated positioning may not
always represent the actual physical position in the application. The manual positioning
option was therefore created for simpler organization or easier interpretation of the
process data word.
A comparison of the addressing, the automated positioning, and the desired positioning
is shown in Figure 3.

Subject to change without notice
21
7 OPERATION
Using SOPAS, the position of a guest can be easily changed via drag & drop (see Figure
4). Note that the sequence number in the process data word also changes depending
on the positioning.
22
To ensure the correct guest has been selected, detailed information about the selected
guest is shown on the right hand side. There is also a “Find Me” function for easily
locating a guest. After selecting a specific guest and pressing the Find Me button, the
LEDs on the selected guest light up.
NOTE
1 Find Me can also be activated during process data operation (PD = valid). Note,
however, that this will have a periodic effect (500 ms) on the cycle time.
2 The Find Me function is automatically deactivated by the device for certain com‐
mands/configurations (Factory reset, Teach-in, Confirm chain change, Automated
assignment, Automated position assignment, Change position, or Teach-in posi‐
tion).

If the option is selected, teach-in is carried out automatically whenever the voltage
supply is interrupted. There must have been no changes to the sensors, otherwise
an AutoAssign must be performed.
There are sensors where the threshold value can only be set manually directly on the
sensor. A teach in via the host is not possible in this case.
The teach-in status should be queried after a teach-in. This returns a response for each
individual slave position.
IOLink307SlaveTeachInStatus can have the following values:
– Teach-in Necessary (0)
is set if the slave at the relevant position has been replaced (serial number has
changed), provided the slave is actually teachable, a teach-in has not already been
carried out at that position, an Automatic assignment, Confirm chain change, Fac‐
tory reset or DataStorage download has been performed.
– OK (1) (the last teach-in was successful)
– Fail (2) (the last teach-in failed, e.g., poor alignment)
This is an immediate teach-in response. It is also retained after a restart, and does
not become a “Teach-in Necessary”.

7.1.3 Zones
– Local Adjustment at Device (optional) (3) (e.g., GTB with local pot)
– Not Available (4) (Slave does not have a teach-in function, for example a sender, or
is completely masked (user mask))
7.1.3.1 Zone definition
The Zones tab can be used to define multiple areas or zones. Up to 16 zones can be
defined.
The zones are displayed, on the one hand, in a table on the right hand side. You can
configure the zones there. The zones are also shown in the system schematic (on the
left).
Specific measurement functions can be defined within each zone. The result is passed
on as an internal output state, which in turn can be used as input for further functions,
or directly outputted via an output. The measurement results of a zone can also be out‐
putted via the serial interface (see also PROCESS DATA).
Automated zone assignment
The “Automated zone assignment” function is performed by “Automated zone assign‐
ment” or “Auto assignment”. When performed, every guest in the zone is assign the
NCB>=1 (number of channels blocked greater than or equal to 1) function. NCB>=1
means that if at least one channel in the zone is blocked, the internal output state is
set to “High”.
The exception to this is zone 1. It is initially defined as the first channel to the last chan‐
nel. If more than 16 guests are connected and the “Automated zone assignment” func‐
tion is performed, the last zone is assigned from Guest16 to Guestmax.
Manual zone assignment
You can individually select each zone in the right hand area of the screen, and config‐
ure the zone in the bottom area. The “Status” column shows whether the internal out‐
put state Qint is active or not.

OPERATION

1 NCB: for object detection or width classification
Example 1: NCB>=1 for object detection (Qint active if at least 1 channel is
blocked)
Example 2 (see graphic): NCB=2 for width classification (Qint active if exactly 2
channels in a zone are blocked)
2 LCB/FCB: for height or position determination
FCB: first channel blocked. This is the blocked channel in the zone that is located
closed to the host.
LCB: last channel blocked. This is the blocked channel in the zone that is located
furthest from the host.
Example: Zone1 extends from channel 1 to 6
LCB >=2: if the last channel blocked in the zone is channel 2 or higher, the internal
output state Qint1 is activated. (right side of graphic)
FCB >=2: if the first channel blocked in the zone is channel 5 or lower, the internal
output state Qint1 is activated. (left side of graphic).

7.1.4 Logics
The Logic tab can be used to further process the individual Qint internal output states
or external signals using logic functions (AND, OR,…). A total of 8 logics are available,
whereby Logixn-x (x>=1 and x<n) can also be used as an input signal for Logicn. The
logic state can be outputted via the switching output or via the serial interface.
Figure 6: Logics tab with two logics
If all logic inputs of a gate are “Not Used”, the result will differ depending on the logic
function selected. This fact can also be used to produce a constant 0 or 1.

4 RS-485 Trigger
Sends data as soon as a signal is high.
5 Sender Off
Test function for simulating object detection: The sender LEDs can be deactivated
via the input. This can be used to test whether the associated receiver LED
responds.
The FlexChain process data word has a length of 32 bytes. Each of these bytes can be
individually populated with the desired data.
Figure 7: Overview of the Process Data tab
Loading process data via profiles
A number of pre-defined process data profiles are available that can be selected to
populate the process data word.
Figure 8: Loading process data via a profile
Manually customizing the process data
Each individual byte of the process data can be customized. After clicking on a byte, a
drop-down list of information that can be assigned to the byte is displayed. The length
of each “information block” is limited to one byte (8 bits). A single byte can therefore be
used, for example, to transmit 8 channel states.

Figure 9: Settings tab
The following settings can be configured in the Settings tab:
1 Local interface lock: Locks the buttons on the display
2 Crosstalk Offset Time: If two identical FlexChain systems are operated in close
proximity to one another, there is a possibility of mutual interference. The
Crosstalk Offset Time changes the cycle time of the FlexChain system. The two sys‐
tems can then no longer interfere with one another due to the different cycle time
and the standard 2-bit processing.
3 “Notification handling” can be used to activate or deactivate events. Various
events such as overtemperature, overvoltage, etc. can be selected. PDinvalid
means invalid process data.
4 Test functions: Deactivates the sender LED. This is used to check whether the
receiver is responding.
5 Factory reset: Restores all settings to the factory defaults. If there are guests con‐
nected to the system, these need to be reassigned using “Automated assignment”,
and then taught in again using “Teach all devices”.
6 Blanked channels: The “blank all currently made/blocked channels” functions can
be used to hide all free or currently blocked beams. This function is useful if there
is a static object in the light path (e.g., light grid). The channels can also be individ‐
ually hidden using Ctrl-left mouse button. Channels that are hidden are no longer
included in the process data.
