Start Assistant

First steps

3.1 Launching the program

Note

In order to query the diagnostic information, the connected AS-Interface safety monitor must
be in protective operation.

If a connection to the AS-Interface safety monitor cannot be established on program startup
(no AS-Interface safety monitor connected, connected to wrong interface etc.) or if the connec­ted AS-Interface safety monitor is in configuration operation, the Diagnostics option is deac­tivated.

In this case, it is only possible to create a new configuration, load and edit a configuration which
has been stored on a data carrier or to search for errors (see chapter 6.2 "Troubleshooting and
error rectification").

Option Diagnostics

When you select the Diagnostics option, first a window opens with the following query. By
clicking Neutral, the diagnostic information of the connected AS-Interface safety monitor is
queried, even if no configuration is loaded in ASIMON.

Note

Querying the diagnostic information of an unknown configuration can take several minutes, as
the configuration of the connected AS-Interface safety monitor must be reconstructed in ASI-
MON. In this way you can load an unknown configuration without needing to exit protective
operation.

Figure 3-2 Query with the Diagnostics option

Next, the Diagnostics window opens (see chapter 6.1 "Diagnostics").

Option New configuration

With the New configuration option, you can create a completely new configuration for the
AS-Interface safety monitor. First, you must enter the base data for the new configuration in
the Information about monitor and bus window. This window is displayed automatically.

Note

The Information about monitor and bus window can be called up at any time. To do this, on
the Edit menu, select the Information about monitor and bus… menu item or click the

button.

Note

If a valid configuration has been loaded to or from an AS-Interface safety monitor, the time at
which the current configuration in the program was transmitted to the AS-Interface safety mo­nitor is shown in the Download time window area.

In the Information monitor tab, you must enter a title for the configuration, select the opera­ting mode, specify whether a safe AS-i output exists and specify the "Basic" or "Enhanced"
function range of the AS-Interface safety monitor.

Operating mode

First steps

3.1 Launching the program

You can select from three operating modes:

•one OSSD

for AS-Interface safety monitors of type 1 or type 3 with 1 OSSD (1 redundant safe relay
output)

• two independent OSSDs

for AS-Interface safety monitors of type 2 or type 4 with 2 independently functioning
OSSDs (2 redundant safe relay outputs)
Select this operating mode when you would like to configure two completely independent
shutdown modes.

• two dependent OSSDs

for AS-Interface safety monitors of type 2 or type 4 with 2 OSSDs (2 redundant safe relay
outputs) in which the second OSSD is dependent on the first (see chapter 4.3.5 "Output
devices").
Special switch-off functions are available in this operating mode.

Note

Prior to a subsequent change of operating mode, determine whether this operating mode is
compatible with the AS-Interface safety monitor type which you are using (see table 3-1).

AS-i output

Here, you specify whether the AS-Interface safety monitor which is to be configured has a safe
AS-i output and whether it is linked to a safe AS-i input. Furthermore, you also specify here
whether a safe actuator is connected or whether the AS-Interface safety monitor functions as
a safe input slave in a coupled AS-Interface network. In this case, you must specify the
AS-Interface address of the actuator or assign the safe input slave an AS-Interface address.

Function range

Here, enter the function range of the AS-Interface safety monitor which is to be configured. The
following table shows how the six device types of the AS-Interface safety monitor differ from

one another:

First steps

3.1 Launching the program

On the Information bus tab, you must enter the AS-Interface bus addresses of the used stan­dard slave and the safety-oriented AS-Interface slaves which are present in this AS-Interface
network.

Figure 3-4 Information about monitor and bus window, Information bus tab

Notice

If you would like to operate two or more AS-Interface safety monitors on the same AS-Interface
bus, you must enter for all AS-Interface safety monitors all safe slaves on this AS-Interface bus
in the Information bus tab even when they are not monitored by the given AS-Interface safety
monitor.

With the Find button, you can also search the AS-Interface bus for slaves when the AS-Inter-
face safety monitor is in configuration operation.

Note

The AS-Interface slaves found when searching the AS-Interface bus are first all listed in the
Information bus tab as standard. You must then manually assign each as safe/standard!

If you clicked the Simulate slaves checkbox on the Diagnosis / Service tab, two or four bus
addresses are automatically assigned for the simulated slaves and the corresponding check­box deactivated. In order to be able to activate Simulate slaves, the one or three addresses
which follow the monitor address must be free.

First steps

3.1 Launching the program

On the Diagnosis / Service tab, you can make service settings for Diagnosis stop and for Re­set of error condition as well as configure the diagnostics via the AS-Interface bus.

Figure 3-5 Information about monitor and bus window, Diagnosis / Service tab

Service settings, Diagnosis stop sub-tab

Figure 3-6 Diagnosis stop sub-tab of the Diagnosis / Service tab

The Diagnosis stop function is activated by clicking the Activate: checkbox. This function is
used when a stop condition is fulfilled (specified AS-Interface standard/A/B slave is in the ON
state) to keep the devices in a ready state (diagnostics LED yellow, waiting for confirmation).
This does not occur with activated local acknowledgement. The diagnosis stop is level-sensi­tive and is deactivated if the specified standard/A/B slave has no bus communication.

This function is very useful, for example, for detecting during very brief switch-off actions which
device, and, thus, which safe input slave caused the switch-off.

Note

For additional information on calling up diagnostic information see chapter "Diagnostics and
error handling" and chapter "Diagnostics via AS-Interface".

First steps

3.1 Launching the program

Service settings, Reset of error condition sub-tab

Figure 3-7 Reset of error condition sub-tab of the Diagnosis / Service tab

By selecting the Activate: checkbox, the global reset of error conditions via one of the stan­dard/A/B slaves connected to the AS-Interface bus is activated.

If a device detects an error, the AS-Interface safety monitor enters the error state. The error
state is locked (error lock). With versions of the AS-Interface safety monitor before 2.0, the er­ror state can be rectified only by resetting the AS-Interface communication or by resetting the
AS-Interface safety monitor by switching off and then switching back on the AS-Interface safety
monitor or by pressing the Service button on the AS-Interface safety monitor.

As of version 2.0 of the AS-Interface safety monitor, it is possible to differentiate the reset of
error conditions (Reset). Reset of error condition can be activated by an AS-Interface standard/
A/B slave, e.g. a button, and acts only on a device level. Thus, the complete safety monitor is
not reset, but rather only the device locked in the error. For a safety monitor with two indepen­dent OSSDs, therefore, only that OSSD is reset in which the device locked in the error is con­figured.

AS-Interface diagnosis

Monitor base address

You can assign an AS-Interface bus address for the AS-Interface safety monitor. In this case,
it is possible to query diagnostic information about the AS-Interface bus from your AS-Interface
master (e.g. the PLC). If you do not assign an AS-Interface bus address, the AS-Interface sa­fety monitor functions strictly as a "listener", i.e. only as a monitor on the bus. It is not possible
to communicate with the safety monitor via AS-Interface in this case.

For assigned monitor base addresses, you can set under Data selection whether the dia­gnostic data are to be output via AS-Interface sorted by OSSD or are to be left unsorted (all

devices) (see chapter 7).

Note

When performing diagnostics via the AS-i, the PLC is informed of the indices of the devices
which are switched off. Previously, if a device was added to or deleted from the configuration,
all subsequent indices were shifted. As a result, it was necessary for the user to modify the
diagnostics program in the PLC.

In the Edit menu of ASIMON version 2.1, you can now use the Device index assignment
menu item to freely assign the diagnosis indices to the devices for AS-Interface diagnostics
(see chapter 7.2 "Assignment of the AS-Interface diagnosis indices").

ASIMON V3 - Configuration software for AS-Interface safety monitor

22 Programming and Operating Manual, Edition 09/2008, GWA 4NEB 333 1558 02 DS 02

First steps

3.1 Launching the program

Simulate slaves

If less than four safe or unsafe AS-Interface slaves are connected to the AS-Interface bus, you
must set Simulate slaves to zero in order for the AS-Interface safety monitor to function
correctly.

The number of simulated slaves can be 1 (for large AS-Interface networks) or 3 (for small
AS-Interface networks).

Note

If Simulate slaves is set unequal to zero, either 1 or 3 additional AS-Interface slaves are
simulated internally. These slaves are automatically assigned the first or first three bus
address(es), respectively, which follow on the AS-Interface safety monitor.

If the Simulate slaves function is activated (number of simulated slaves: 1 or 3), the state of
the relay- and message outputs can be queried by the AS-Interface master (PLC) via the
AS-Interface at monitor base address+1, data bits D3 … D0. Bit state 0 identifies an inactive
output, bit state 1 an active output, corresponding to the substitute value in the process image

of the AS-Interface master.

Data bit Content

D0 State of relay output 1
D1 State of message output 1
D2 State of relay output 2
D3 State of message output 2

According to this, the AS-Interface safety monitor occupies a different number of bus
addresses in the AS-Interface network:

Number of

occupied bus

addresses

0 No bus address was assigned to the AS-Interface safety monitor. No communi-

cation and, thus, no diagnostics possible via AS-Interface with the safety moni­tor.

1 One bus address was assigned to the AS-Interface safety monitor. Diagnostics

possible via AS-Interface with the safety monitor. Number of simulated slaves
equal to 0.

2 One bus address was assigned to the AS-Interface safety monitor. Diagnostics

possible via AS-Interface with the safety monitor. Number of simulated slaves
equal to 1. State of relay- and message outputs can be accessed via AS-Inter­face at monitor base address+1 (monitor version 2.12 and higher).

4 One bus address was assigned to the AS-Interface safety monitor. Diagnostics

possible via AS-Interface with the safety monitor. Number of simulated slaves
equal to 3. State of relay- and message outputs can be accessed via AS-Inter­face at monitor base address+1 (monitor version 2.12 and higher).

First steps

3.1 Launching the program

Option Open configuration

With the Open configuration option, you can open an existing configuration file (*.asi) which
was previously stored on a data carrier for purposes of editing or transmitting to an AS-Inter­face safety monitor.

Figure 3-8 Opening a stored configuration file

Note
ASIMON configuration files have the extension *.ASI (version 1 AS-Interface safety moni-

tors), *.AS2 (version 2 AS-Interface safety monitors) or *.AS3 (version 3.x AS-Interface
safety monitors).

Option Load configuration from AS-Interface safety monitor

Note

If a connection to the AS-Interface safety monitor cannot be established on program startup
(no AS-Interface safety monitor connected, connected to wrong interface etc.) or if the connec­ted AS-Interface safety monitor is in protective operation, the Load configuration from AS-In-
terface safety monitor option is deactivated.

In this case, it is only possible to create a new configuration, load and edit a configuration which
has been stored on a data carrier or to search for errors (see chapter 6.2 "Troubleshooting and
error rectification").

When you select the Load configuration from AS-Interface safety monitor option, the con­figuration of the connected AS-Interface safety monitor is queried and displayed in the main
program window.

Checkbox Show dialog on startup

When this checkbox is activated, the Start Assistant is called up each time the ASIMON pro-
gram is started. If you do not wish to use this program feature, simply deactivate this checkbox
and the Start Assistant will no longer automatically be opened on program startup.

On the Extras menu under Use Start Assistant, you can reactivate or deactivate the automa­tic call of the Start Assistant on program startup at any time.

3.2 Description of the user interface

Window

The work area may contain any number of windows. The functions in the Window menu are
available for arranging the windows.

As in the past, a device is inserted from the icon library using drag&drop. All windows are ini­tially equal. A window becomes an OSSD window by inserting an output device. If all OSSDs
are defined by a separate configuration window, no further output devices can be inserted in
other windows.

In addition to the OSSD windows, which contain the actual configuration for an AS-Interface
safety monitor, you can use other windows to form substructures (sub-devices) and create
user devices.

Note

The Preprocessing window area familiar from previous software versions no longer exists.
For AS-Interface safety monitors of types 1 and 2 with "Basic" function range, the only possible

logic device available for the linking of two monitoring or system devices is the logic OR func­tion.

In the 1st OSSD and 2nd OSSD windows, the monitoring devices (safe AS-Interface slaves),
start devices, external device monitoring devices, system devices, logic devices and output de­vices are grouped into the desired configuration and linked to one another using the logical
AND function. Very complex functions can be created in this way.

Operation

Note

The view in the window is updated by pressing the <F5> key; i.e. the window contents are re­drawn on the screen.

To paste devices from the icon library into the other windows, as well as to edit, delete, move
and copy devices between the windows, various options are available depending on your per­sonal preference:

• With the mouse:

-by drag&drop from the icon library:
click device with the left mouse button, keep mouse button pressed, and move the de­vice. Simultaneously press the <Ctrl> key for further options:

- If devices are pulled from the selection list to a window with the mouse, the device is

Configuring the AS-Interface safety monitor 4

Configuring the AS-Interface safety monitor

The AS-Interface safety monitor is a universally usable protective device and can, therefore,
be configured for a very wide range of applications.

4.1 Function of the AS-Interface safety monitor

The functional task of the AS-Interface safety monitor is to continuously specify the state(s) of
the OSSD(s) in accordance with the configuration specified by the user based on the states of
the configured devices and to activate or deactivate the assigned safe switching outputs or
safe actuators.

The ASIMON software automatically arranges the devices in the respective windows during
configuration.

Each device can take on two states:

ON state (switched on, logical "1")

This state means that the device has agreed to validate the circuit, i.e. to activate the safe
switching outputs. Depending on the device type, various conditions must first be met.

OFF state (switched off, logical "0")

This state means that the device has not agreed to validate the circuit, i.e. it results in the
switching off of the safe switching outputs.

In the first step of the evaluation, the states of all monitoring, logic and EDM devices are linked
to one another by means of a global logic AND function, i.e. only when all configured monito­ring, logic and EDM devices have the ON state is the result of the AND function equal to ON.
In principle, the device states are evaluated in the same way as in an electrical safety circuit in
which all safety switch elements are connected in series and validation is possible only when
all contacts are closed.

In the second step, the start devices which determine the startup behaviour of the OSSD are
evaluated. A start device enters the ON state when the result of the global AND function from
the first step of the evaluation is equal to ON and when the respective start condition is fulfilled.
With regard to the start condition, the start devices have a lock. The start condition must the­refore only be fulfilled once. A start device is reset (OFF state) when the result of the global
AND function from the first step of the evaluation returns the OFF state. The states of the start
devices used are linked to one another with an OR function, i.e. only one of the start devices
needs to be in the ON state in order for the internal validation of the circuit to occur.

The process is identical for all device variants of the AS-Interface safety monitor (1 or 2
OSSDs, "Basic" or "Enhanced" function range, with or without safe AS-Interface output).

Step 1 - Information about monitor and bus

In order to create a new configuration, you must first make the required entries in the Informa­tion about monitor and bus window for the AS-Interface safety monitor and the slaves which

are to be monitored (see “Start Assistant” on page 17):

• Assign the configuration title

• Specify operating mode of the AS-Interface safety monitor

- One OSSD

- Two independent OSSDs

- Two dependent OSSDs

• Specify safe AS-i output if necessary

- Linked to AS-i input

Configuring the AS-Interface safety monitor

4.2 General procedure

- Control of a safe actuator or safe input slave in the coupled AS-i network

• Specify function range of the AS-Interface safety monitor

- "Basic" or "Enhanced" function range

• Enter the AS-Interface bus addresses of the safe and unsafe AS-Interface slaves which
are to be monitored

• If necessary, activate diagnosis stop via Standard slave

• If necessary, activate reset of error condition via Standard slave

• Activate diagnostics via AS-Interface

- Enter the AS-Interface bus address of the AS-Interface safety monitor

- Selection of the diagnostic data: sorted by OSSD or by all devices

- If necessary, activate the option 1 or 3 Simulate slaves

Step 2 - Create configuration

You can now assemble a new configuration with the required devices from the icon library. see
“Creating and changing a configuration” on page 40. In addition, in ASIMON version 2.1, you
can freely assign the devices diagnosis indices for the AS-Interface diagnostics. see “Assign­ment of the AS-Interface diagnosis indices” on page 165.

Step 3 - Commissioning

After you have created a valid configuration, you can commission the AS-Interface safety mo­nitor. The commissioning procedure is described in chapter 5.

4.3 Creating and changing a configuration

4.3 Creating and changing a configuration

A valid configuration for the AS-Interface safety monitor must consist of the following devices
for each independent OSSD:

• at least 1 monitoring device

• at least 1 start device (with two dependent output groups, only for OSSD 1)

• exactly 1 output device (with two dependent output groups, only for OSSD 1)

The maximum number of devices is dependent on the function range of the AS-Interface safety
monitor type:

• function range "Basic":maximum 32 devices (device index 32 … 63).

• function range "Enhanced":maximum 48 devices (device index 32 … 79).

Procedure

Select a device from the icon library and insert it into the window of the desired OSSD (see
“Operation” on page 30).

Note

Detailed information about which devices can be used with which configurations can be found
in the description of the individual devices.

When you insert the device into a window, the input mask for the device first opens. Here, you
can make all required entries for this device.

This includes information such as:

• designation (name) of the device within your application, e.g. "Lock gate1"

• type, e.g. "double channel forced"

• AS-Interface bus address

• additional device options which can be activated

• monitoring and delay times

After confirming your entries with the OK button, the device appears in the window of the re­spective OSSD.

Note

The view in the window is updated by pressing the <F5> key; i.e. the window contents are re­drawn on the screen.

Example:

Figure 4-2 Graphic depiction of the devices

In addition to icon, designation and name, the respective device index for each device is spe­cified. The index, which is automatically assigned by ASIMON for each configured device,
uniquely identifies each device, regardless of whether it has been configured for the first or se­cond OSSD.

The index begins with 32 and increases incrementally by 1. Within the configuration log, each
configured device can be uniquely identified using the index.

Note

The display of the devices can be modified.

To do this, on the Extras menu select the Display options… menu item or click the button
(see chapter 3.2.4 "The work area").

Note

When performing diagnostics via the AS-i, the PLC is informed of the indices of the devices
which are switched off. Previously, if a device was added to or deleted from the configuration,
all subsequent indices were shifted. As a result, it was necessary for the user to modify the
diagnostics program in the PLC.

In the Edit menu of ASIMON version 2.1, you can now use the Device index assignment
menu item to freely assign diagnosis indices to the devices for AS-Interface diagnostics (see
chapter 7). When making the assignments, you can specify whether the diagnosis index range
is 0 … 47 or analogous to the device indices 32 … 79.

4.3 Creating and changing a configuration

ASIMON automatically organises all devices of a configuration with respect to the device indi­ces in the following order:

1. Monitoring and logic devices in any order

2. External device monitoring (EDM) devices (contactor monitoring)

3. Start devices

4. Output device

Upon insertion of a new device, the indices are correspondingly rearranged.

Note

A monitoring or logic device configured in the 1st OSSD can also be used in the 2nd OSSD
and vice versa.

You can define a device or a logical group of devices as a user device; this user device can
then very easily be used multiple times in the OSSDs.

Example:

Figure 4-3 Example: Structure of a configuration

To delete a device from the configuration, mark it with the mouse and then select the Delete
command from the Edit menu or the pop-up menu (right mouse button) or simply press the
<Delete> key.

To edit a device, double-click its icon to reopen its input mask. Here, you can edit all device
parameters. Alternatively, you can use the Device parameters… command in the Edit menu
or the Edit … command in the pop-up menu.

4.3.1 Monitoring devices

The monitoring devices constitute the actual safe switching components of the OSSD(s) in the
configuration.

For the safe monitoring devices, a distinction is made depending on type between:

Double channel, forced components

Upon actuation of an emergency-off switch with its two redundant contacts, the two contacts
open simultaneously. As a result of this construction, both contacts are always either open or
closed. If one of the two contacts closes or opens either too early or too late, an error results
after a tolerated transition time has passed.

The functional device for double channel, forced components can, thus, be used for applica­tions such as

• emergency shutdown switches

• safety guards

• active optoelectronic protective device

• zero-speed relays

Configuring the AS-Interface safety monitor

4.3 Creating and changing a configuration

Here, both the direct connection of an integrated AS-Interface slave as well as the connection
of a conventional device via a safe coupling module are possible. Local acknowledgement and/
or the startup test are available as options.

Double channel, dependent components

The monitoring to determine whether a safety guard is open or closed is performed by two pro­tective switches. If this safety guard is opened or closed, the protective switches are not actu­ated simultaneously. In the double channel dependent functional device, a synchronisation
time can, therefore, be specified. Both switches must close within this synchronisation time. If
the synchronisation time is exceeded, the start-test state results.

The safety monitor also monitors the switches to ensure that one of the two end positions "both
switches open" or "both switches closed" is always achieved.

The functional device for double channel, dependent components can, thus, be used for appli­cations such as

• safety guards with two protective switches

• two-handed operations

Here, both the direct connection of an integrated AS-Interface slave as well as the connection
of a conventional device via a safe coupling module are possible. Local acknowledgement and/
or the startup test are available as options.

4.3 Creating and changing a configuration

Double channel, dependent components with debouncing

Note

These components are only available for the types of the AS-Interface safety monitor with en­hanced function range (type 3 … type 6).

The monitoring to determine whether a safety guard is open or closed is performed by two pro­tective switches. If this safety guard is opened or closed, the protective switches are not actu­ated simultaneously. Moreover, the switches bounce, for example when the guard is closed
too fast. In the double channel dependent functional device with debouncing, it is, therefore,
also possible to specify a bounce time in addition to the synchronisation time. The bounce time
begins when both contacts close the first time. Within the specified bounce time, the switches
can change their state freely. After the bounce time has passed, both contacts are again que­ried. If they are then closed and if the synchronisation time has not yet passed, the validation
is performed. The selected synchronisation time must be greater than the bounce time. If the
synchronisation time is exceeded, the start-test state results. The safety monitor also monitors
the switches to ensure that one of the two end positions "both switches open" or "both switches
closed" is always achieved.

The functional device for double channel, dependent components with debouncing can, thus,
be used for applications such as

• slow-action switch

• switches with high bounce times

Here, both the direct connection of an integrated AS-Interface slave as well as the connection
of a conventional device via a safe coupling module are possible. Local acknowledgement and/
or the startup test are available as options.

Double channel, dependent components with filtering

Note

These components are only available for the types of the AS-Interface safety monitor with en­hanced function range (type 3 … type 6).

The monitoring to determine whether a safety guard is open or closed is performed by two pro­tective switches. If this safety guard is opened or closed, the protective switches are not actu­ated simultaneously. In addition, guard vibrations may result in short-term, single-channel
interruptions. This monitoring device can be used to "filter out" such interference without cau­sing the system to be switched off. The user defines a synchronisation time, a stabilising time
and, if necessary, a tolerance time for short-term, single-channel interruptions. When switched
on, the protective switch may switch between all possible states (none, one, or both contacts
closed) during the synchronisation time.

If both contacts remain open for the duration of the stabilising time, the synchronisation time is
restarted when the contacts are again closed. If the protective switch is in an undefined state
for the duration of the stabilising time, the functional device switches to the locked error state.
Only if both contacts close within the synchronisation time and remain closed for the duration
of the stabilising time is the validation performed.

The functional device offers various possibilities for handling short-term, single-channel inter­ruptions. Local acknowledgement and/or the startup test are available as options.

4.3 Creating and changing a configuration

Double channel, conditionally dependent components

Note

These components are only available for the types of the AS-Interface safety monitor with en­hanced function range (type 3 and type 4).

The monitoring to determine whether a safety guard is open or closed is performed by a pro­tective switch with lock. One contact is switched by the protective switch, the second by the
lock monitor. If the lock is opened, the guard can also be opened. This sequence of events is
monitored. It is an error if the protective switch opens first.

Which contact is dependent on which can be freely selected in the double channel conditionally
dependent functional device. The dependent contact can be freely opened and closed as long
as the independent contact is not opened.

The functional device for double channel, conditionally dependent components can, thus, be
used for applications such as

• door switch with lock

Here, both the direct connection of an integrated AS-Interface slave as well as the connection
of a conventional device via a safe coupling module are possible.

Notice

As a result of the permissible, independent actuation, a loss of redundancy is not detected!

Double channel, independent components

The monitoring to determine whether a safety guard is open or closed is performed by a pro­tective switch with lock. One contact is switched by the protective switch, the second by the
lock monitor. With this functional device, it is possible to open and close the lock without forcing
the guard to open or close.

The functional device for double channel independent components can, thus, be used for ap­plications such as

• protective switch for door monitoring

Here, both the direct connection of an integrated AS-Interface slave as well as the connection
of a conventional device via a safe coupling module are possible. Local acknowledgement
and/or the startup test are available as options.

Notice

As a result of the permissible, independent actuation, a loss of redundancy is not detected!

4.3 Creating and changing a configuration

Standard slave

Within an OSSD, it is also possible to use standard AS-Interface slaves in order to realise, by
means of their switching signals (inputs or outputs), an exclusively operational switching of the
safe switching outputs of the AS-Interface safety monitor in an OSSD.

Notice

The use of a standard slave device for safe switching tasks is not permitted!

Monitor input

Within the OSSDs or preprocessing, the input signals of the 2 or 4 inputs 1.Y1, 1.Y2 and

2.Y1, 2.Y2, respectively, of the AS-Interface safety monitor can also be used to implement
strictly operational switching of the safe switching output(s) of the AS-Interface safety monitor
in an OSSD.

Notice

The use of a monitor input device for safe switching tasks is not permitted!

Button

The Button device can be integrated within the OSSD or Preprocessing. The Button device
makes acknowledgement possible on the device level. As soon as the validation for the device
which is linked to the button is present, this device can be validated by actuating the button,
i.e. acknowledged.

With the aid of the Device button, it is possible, for example, to assign a common local
acknowledgement to multiple light barriers which have been linked together by an AND gate.

NOP

Dummies (NOP - N

o OPeration) can be used within an (OSSD) window to make the configu­ration or the graphical display in ASIMON easier to organise or to create a sample configura­tion to be used as a pattern for different configuration variants. An NOP dummy occupies an
index within the configuration. Each functional device can be replaced by an NOP dummy and
vice versa.

4.3 Creating and changing a configuration

Zero sequence detection

The zero sequence detection monitoring device can be used to monitor whether both switches
of a safe input slave are open. The device switches to the ON state when the value 0000 is
continuously transmitted by the safe slave.

Notice

The use of a zero sequence detection device for safe switching tasks is not permitted!

Application icons

The safe monitoring devices generally differ from one another only in type, e.g. double channel
dependent. From an application perspective, a device of the same type can be used both as a
safety guard as well as for two-handed operation.

Described in the following are the safe monitoring devices organised according to type. In the
icon library, you must first select the application icon for the desired device and then select the
respective type in the input mask.

To the left of the application icon in the configuration window, the type icon (double channel
forced, double channel dependent, double channel independent, etc.) is displayed for all safe
monitoring devices in order to clearly represent the configuration with a practical perspective.
The input mask of the application icons offers all device options, even if e.g. a local acknow­ledgement for a two-handed operation does not make much sense.

Device options

Many monitoring devices also possess, in addition to their safe switching behaviour, options
which can be used to realise more complex applications. These include:

Startup test

The startup test is used, for example, when the proper function of a safety guard is to be in­spected prior to starting the machine. In this case, the startup test requires that the guard be
opened and closed again before the machine is started. Only then can the machine be started.

47

Configuring the AS-Interface safety monitor

4.3 Creating and changing a configuration

Local acknowledgement

Local acknowledgement is used, for example, when a safety guard is located in an area not
visible from the control desk. With local acknowledgement, acknowledgement (i.e. a confirma­tion that no persons are present in this part of the machine) can only be performed from the
local operating desk.

In terms of the AS-Interface bus, an additional switching signal is linked to the monitoring de­vice. Only if this switching signal was active is the monitoring device validated in the safety mo­nitor. The switching signal for the local acknowledgement can be a standard slave, an A/B
slave or the non-safe OUT bits of a safe input slave whose AS-Interface bus address and bit
address must be specified.

Note

Certain time conditions apply to the arrival of the signals. These are illustrated using a safety
light barrier as an example:

1. Between the release of the safety light barrier and the actuation of the local acknow­ledgement, at least 50ms must pass.

2. An actuation of the local acknowledgement is evaluated as valid when the switching
signal is present for a minimum of 50ms and a maximum of 2s.

3. After the local acknowledgement is released, the monitoring device is validated fol­lowing a wait period of 50ms.

The available monitoring devices are described individually below.

Note
The functional devices and their variants, e.g. double channel forced safety input with

startup test, included in the devices described below can be found in this form in the configu-

ration log of the AS-Interface safety monitor (see chapter 5.8 and examples of the respective
monitoring devices).

4.3 Creating and changing a configuration

Description

With the double channel dependent monitoring device, both switching signals of the respec­tive safe AS-Interface slave each act on 2 bits of the transmission sequence. In this case, both
of the switching signals must arrive within a synchronisation time defined by the user. If only
one contact opens, the second contact must still open before both contacts can be closed
again.

Optionally, a startup test and/or a local acknowledgement are/is possible. Upon activation of
the Also acknowledge after startup checkbox, local acknowledgement is always mandatory
even after switching on the AS-Interface safety monitor or following a communication error
(warm start of the AS-Interface safety monitor).

Note

If the synchronisation time defined by the user is exceeded, the activation must be repeated.
If the synchronisation time is set to infinite (∞), the AS-Interface safety monitor does not grant
the validation until the second switching signal arrives.

4.3 Creating and changing a configuration

Description

With the double channel dependent with debouncing monitoring device, both switching si­gnals of the respective safe AS-Interface slave each act on 2 bits of the transmission sequen­ce. In this case, both of the switching signals must arrive within a synchronisation time defined
by the user.

For debouncing the contacts, a bounce time can be defined. During this time, the contacts are
not evaluated. The bounce time begins when both contacts close the first time. After the
bounce time has passed, both contacts are again queried. If they are then closed and if the
synchronisation time has not yet passed, the validation is performed. The selected synchroni­sation time must be greater than the bounce time.

Note

The set bounce time is always allowed to pass. This means that if a bounce time of 10s is set,
then the device is validated no sooner than this time.

If only one contact opens, the second contact must still open before both contacts can be
closed again.

Note

If the synchronisation time defined by the user is exceeded, the activation must be repeated.
If the synchronisation time is set to infinite (∞), the AS-Interface safety monitor does not grant
the validation until the second switching signal arrives.

Optionally, a startup test and/or a local acknowledgement are/is possible. Upon activation of
the Also acknowledge after startup checkbox, local acknowledgement is always mandatory
even after switching on the AS-Interface safety monitor or following a communication error
(warm start of the AS-Interface safety monitor).

Description

Configuring the AS-Interface safety monitor

4.3 Creating and changing a configuration

With the double channel dependent with filtering monitoring device, both switching signals
of the respective safe AS-Interface slave each act on 2 bits of the transmission sequence. The
user defines a synchronisation time, a stabilising time and, if necessary, a tolerance time.
When switched on, the protective switch may switch between all possible states (none, one,
or both contacts closed) during the synchronisation time.

If both contacts remain open for the duration of the stabilising time, the synchronisation time is
restarted when the contacts are again closed. If the protective switch is in an undefined state
for the duration of the stabilising time, the functional device switches to the locked error state.
Only if both contacts close within the synchronisation time and remain closed for the duration
of the stabilising time is the validation performed.

The functional device offers 3 possibilities for handling short-term, single-channel interrup­tions.

• If the shutdown with test request is activated, the functional device always calls for re­start with test request.

• If shutdown without test request is activated, the functional device calls for restart with
test request only for single channel interruptions which have lasted longer than the set to­lerance time.

• If tolerancing without shutdown is selected, shutdown in the event of single channel in­terruptions only occurs after the tolerance time has passed. Note here that the reaction
time is extended by the set tolerance time!

4.3 Creating and changing a configuration

Notice

If tolerancing without shutdown is selected, shutdown in the event of single channel interrupti­ons only occurs after the tolerance time has passed. The reaction time is extended by the set
tolerance time!

The set tolerance time in the "Tolerancing without shutdown" operating mode must not exceed
one tenth of the average time between two actuations of the monitored switch!

Example:
The shortest time between 2 opening operations of a safety guard is 5 s.
The set tolerance time in this case may be maximum 0.5 seconds.

Optionally, a startup test and/or a local acknowledgement are/is possible. Upon activation of
the Also acknowledge after startup checkbox, local acknowledgement is always mandatory
even after switching on the AS-Interface safety monitor or following a communication error
(warm start of the AS-Interface safety monitor).

4.3 Creating and changing a configuration

Description

With the double channel conditionally dependent monitoring device, both switching signals
of the respective safe AS-Interface slave each act on 2 bits of the transmission sequence. In
order for the second, dependent switching signal to be accepted in this case, the first switching
signal must be present. Which contact is dependent on which can be freely selected. It is an
error if the second, dependent switching signal arrives before the first switching signal.

Example: A door switch with locking. One contact is operated by the door switch (independent
contact), the second by the lock monitor (dependent contact). Only if the door is closed, the
lock can be opened and closed. An opened door contact with the lock closed is an error.

Caution

Double channel conditionally dependent monitoring devices offer only limited safety, as they
cannot be checked for simultaneousness. Check carefully to ensure that the use of a double
channel conditionally dependent monitoring device fulfils the requirements of the desired sa­fety category.

4.3 Creating and changing a configuration

Description

The standard slave monitoring device is used to integrate one bit (input or output) of a non­safe, standard AS-Interface switching signal as an additional switching signal for operational

switching of the AS-Interface safety monitor relay(s) in an OSSD.

Note

With the input and output bits of a non-safe, standard AS-Interface slave, the process image
is always analysed, i.e. the ON state always means an active signal in the process image.

With the standard slave, the output bits of a slave address can also be used. In this way it is
possible to react to a signal from the controller as well. As of version 2.0 the slaves simulated
by the monitor can also be used for this purpose.

If the Inverted parameter is activated, the inverter icon precedes the icon for the standard sla­ve device in the configuration.

Notice

The use of a standard slave device for safe switching tasks is not permitted!

The Button device can be integrated within the OSSD or Preprocessing. The Button device
makes acknowledgement possible on the device level. As soon as the validation for the device
which is linked to the button is present, this device can be released by actuating the button, i.e.
acknowledged (device switches to the ON state). If the device is not validated before the
acknowledgement arrives, the device switches to the OFF state.

Note

This function requires that the button remain unactuated after the validation condition has been
fulfilled for at least 50ms and then be actuated for at least 50ms yet for no more than 2s. After
the button is released, the device switches to the ON state after an additional 50ms for the time

make the configuration or the graphical display in ASIMON easier to organise or to create a
sample configuration to be used as a pattern for different configuration variants. An NOP dum­my occupies an index within the configuration. Each functional device can be replaced by an
NOP dummy and vice versa.

Note

With NOP devices, make certain that the status values are assigned correctly in the configu­ration. In AND logic operations, NOP devices should be assigned the ON state; in OR logic

Description

The zero sequence detection monitoring device can be used to monitor whether both swit­ches of a safe input slave are open. It is used to perform operational switching tasks. The de­vice switches to the ON state when the value 0000 is continuously transmitted by the safe
slave. With zero sequence detection, safe input slaves which are included at a different point
in the configuration can also be monitored. And vice versa, the address selected for zero se­quence detection for monitoring devices remains available.

Notice

In the event of a defect or error, e.g. insufficient voltage at the slave, the ON state can also be
achieved when both switches are closed. For this reason, it is not permitted to use a zero
sequence detection device for safe switching tasks!

4.3.2 Logic devices

In more complex safety tasks, the various input signals and intermediate states must be linked
– something not possible with the global AND. Logic devices are available for this purpose:

• Logical AND operation

• Logical OR operation

• R/S FlipFlop with SET and HOLD input

• Switch-on delay

• Switch-off delay

• Pulse on positive edge

Note

You can also link monitoring devices from the other OSSD by assigning them to a logic device.
For AS-Interface safety monitors of types 1 and 2 with "Basic" function range, the only possible

logic device available for the linking of two monitoring or system devices is the logic OR func­tion.

Example 1:

Figure 4-4 Logic device example

In the example shown here, the OR logic device switches to the ON state (switched on) when
the active optoelectronic protective device "LG1" is in the ON state (switched on) or the safe
switching output of the second OSSD is activated (relay triggered) or both conditions are true.

4.3 Creating and changing a configuration

Description

With the OR logic device, up to 6 monitoring or system devices are linked to one another via
the logic OR function.

The OR logic device is in the ON state when at least one of the linked devices has the ON
state.

Notice

In the configuration of the AS-Interface safety monitor, the same functional devices can be
used e.g. for a light barrier and an emergency-off switch. When configuring, you must pay at­tention to which safety functions may and which may not be bridged.

An application which can make use of the OR logic device is, for example, a material lock in
which the machine may only be put into operation when at least one of the two lock gates is
closed.

Description

With the Pulse on pos. edge logic device, an ON pulse with adjustable pulse duration is created
if a monitoring or system device changes state from OFF to ON.

The state of the Pulse on pos. edge logic device is calculated according to the following table:

Linked device Result of the link

switched off (OFF) switched off (OFF)
switched on (ON) switched on (ON) for the length of time set under

pulse duration
other switched off (OFF)

Notice

While the ON pulse is present at the output, the input is not monitored, i.e. a change of the
input state during the ON pulse is not evaluated and has no effect on the ON pulse. The func­tion of the device corresponds to a non-retriggering monoflop.

Notice

Even a short communication error on the AS-Interface line results in an ON pulse at the output!

4.3.3 External device monitoring devices

External device monitoring devices (also called EDM devices - External Device Monitor) are
used for realising dynamic contactor monitoring for a configuration of the AS-Interface safety
monitor. If no EDM device is configured, contactor monitoring is deactivated.

Note

Multiple EDM devices can be integrated in an OSSD.

For example, with dynamic contactor monitoring, the motor contactors connected downstream
of the safety monitor for the potentially dangerous movement are connected to the safe swit­ching outputs of the AS-Interface safety monitor. Via a feedback control loop, the state of the
contactors is monitored by the input contactor monitor on the AS-Interface safety monitor.

Note

Additional information about the electrical design and connection of a contactor monitor can be
found in the operating manual of the AS-Interface safety monitor.

Reset of error condition

If a device detects an error, the AS-Interface safety monitor enters the error state. The error
state is locked (error lock). With versions of the AS-Interface safety monitor before 2.0, the
error state can be rectified only by resetting the AS-Interface safety monitor by switching off
and then switching back on the AS-Interface safety monitor or by pressing the Service button
on the AS-Interface safety monitor.

With software versions of the AS-Interface safety monitor > 2.0, the reset of error conditions
(Reset) on the device level after OSSDs is possible, i.e. via an AS-Interface standard/A/B
slave, e.g. a button can trigger the error lock (see chapter 3.1 "Launching the program").

Description

As long as the safe outputs are switched off, the input contactor monitor on the AS-Interface

the input contactor monitor is not relevant for set switching time. Afterward, the input must be
inactive = OFF. The state of the contactor monitor is active = ON (switched on).

After the safe outputs have been switched off, the state of the contactor monitor returns to
inactive = OFF (switched off) and the input contactor monitor is not queried for the set
switching time. Afterward, the input contactor monitor must again be active = ON.

Contactor monitoring prevents the monitor from being switched back on for the duration of the
set switching time after it is switched off. This should allow all downstream contactors to reach
the idle state before contactor monitoring again queries the input signal, thereby preventing an
error lock.

monitor switches the safe outputs of the OSSD back off.

Notice

automatic start is not permitted, as in this combination it is possible for the safe outputs of the
AS-Interface safety monitor to be continuously switched on and off.

4.3.4 Start devices

In the course of the analysis, after all monitoring, logic and EDM devices have been processed,
the result of the AND link of all device states is determined for each OSSD. In the start devices,
this result is analysed together with a possible start condition.

For each independent OSSD, at least one start device is required. If multiple start devices are
present in an OSSD, they are linked with one another by means of an OR function. Thus, for
the validation of an OSSD, it is sufficient when one of the start devices fulfils the condition for
the validation.

Possible start conditions are:

• Automatic start (no additional start condition)

• Monitored start by means of an AS-Interface standard slave

• Monitored start by means of start input on the AS-Interface safety monitor

• Monitored start by means of a safe AS-Interface slave

• Activation via standard slave

• Activation via monitor input

4.3 Creating and changing a configuration

Note

A start device can only be assigned to one OSSD. If, for example, both OSSDs are to be star­ted with one button, a start device is to be configured for each OSSD. Both of the devices, ho­wever, use the same button.

Description

The "automatic start" start device requires no additional start condition. If the AND link for all
monitoring, logic and EDM devices of an OSSD returns the result ON, the "automatic start"
start device releases the OSSD via the respectively configured output device.

Danger

In the event of an automatic start, the OSSD switches on as soon as all conditions are fulfilled!
The machine can, in this case, start unexpectedly!

Note

The combination of the automatic start start device with other start devices is not useful, as
a start would occur in every case.
