2.3 Start-up behaviour of the controller
6827
15233
11575
215
A restart can, for example, be caused by:
• voltage restoration after power failure
• reset after watchdog response because of too long a cycle time
• error elimination after an E-stop
To ensure a safe behaviour of the controller:
► Monitor the voltage supply in the application program.
► In case of an error switch off all relevant outputs in the application program.
► Monitor actuators which can cause hazardous movements in the application program (feedback).
► Monitor relay contacts which can cause hazardous movements in the application program
(feedback).
► If necessary, ensure that welded relay contacts in the application project cannot trigger or continue
hazardous movements.

3.2 What is IO-Link?
5123
>
3.2.1 Introduction
5300
For fieldbuses one master communicates with several slaves which the master distinguishes on the
basis of the slave addresses. The sensors and actuators connected to the slaves perform either binary
or analogue operation. The slaves have to be equipped correspondingly. The parameters of the
sensors and actuators can be set during operation.
The IO-Link enables the operation of "smart" sensors and actuators on the existing fieldbus via special
modules. IO-Link sensors provide additional diagnostic information on a 3-pole standard cable besides
the normal switching output.
IO-Link is an open system: independent of the fieldbus and the manufacturer. The diagnostic interface
is supported by all leading bus systems.
Only the serial communication between the master and the slave are features both of the IO-Link and
the fieldbuses. Everything else is different:
There is no address setting since the data are only exchanged between two participants.
The IO-Link master communicates with the connected IO-Link device via a point-to-point
connection.
Remote parameter setting of the IO-Link device via the fieldbus is possible.
Advantages of the IO-Link system:
existing cable topology (here: standard AS-i cables) remains unchanged,
thanks to the point-to-point connection addressing of the devices is not necessary;
transmission of diagnostic data without additional wiring: exchange of process data and service
data between sensors / actuators and the controller,
transmission of analogue values without conversion losses,
fully compatible: Use in parallel to standard devices on the same bus.

5124
3.3.1 User characteristics
5125
The presetting of the AS-i link gateway ensures operation of two sensors with two words of cyclic data
(process data) each.
The IO-Link port configuration can be changed via function blocks in a higher-level controller or a
configuration software on a service PC.
It is also possible to change the setting of the IO-Link devices via function blocks on the control level.
To do so the data are to be sent to the AS-i module via AS-i function calls. Then the AS-i IO-Link
gateway acts as a transparent transport channel*) and transfers the data to the connected device.
*) "transparent transport channel" means: The data are left unchanged over the whole communication line. Only the transfer
protocol changes between the AS-i and the IO-Link systems.
>
3.3.2 System interface
5126
The system interface is a largely transparent communication interface between the AS-i and the IOLink system. Transparency is restricted since the device is largely initiated automatically using default
values.
>
3.3.3 User interface
5127
The device does not feature a user interface. It is indirectly available as function calls. Settings of the
module and the connected IO-Link devices can be changed via these calls.
>
3.3.4 Software interface
The device only runs on AS-I masters with master profile M4 complying with the AS-i specification
V3.0 [AD5]. To be able to use all functions the master must also support the CTT2 protocol calls for
device groups amended in revision 2.

3.3.5 Communication interface
The device has 2 communication interfaces:
via an AS-i communication to the usual AS-i standard to specification V3.0 [AD5],
via an IO-Link interface per port.
The IO-Link interface is implemented to specification 1.0 [AD1] or partly in anticipation of the
specification 1.1 [AD2].
(Overview of the specifications chapter Approvals, standards to IO-Link (→ page 45))
>
3.3.6 Operating states
The AS-i IO-Link gateway provides the following operating states:
Start-up
During reset / switch-on the module verifies the identity of the connected IO-Link devices
(manufacturer ID, device ID, function ID). In the "plug & comm" mode the identity check is not
made. Then cyclic operation is started.
If the "plug & comm" mode is not active, a newly connected device has to be configured before its
first use.
Cyclic operation
On the AS-i side data are exchanged normally, i.e. cyclically and acyclically.
On the IO-Link side normal operation is cyclic.
The gateway application assigns the data....
- referred to the port from AS-i to the IO-Link or
- referred to the port from the IO-Link to AS-i.
Error state with non-compatible device
If the connected device does not comply with the requirements, the gateway application signals
this to the higher-level system and waits for the connection of the correct device.
Error in the IO-Link communication
The faulty communication is displayed via a red LED on the respective IO-Link port. Errors,
messages and warnings from the IO-Link application trigger a periphery fault in the AS-i part
depending on the hardness set.
Removing and connecting the AS-i slave.
During operation you may remove the AS-i slave from the bus and connect another one or the
same one again. After connection of the AS-i slave rebooting is started in the same way as for
start-up ( above).
Removing and connecting IO-Link devices
During operation you may remove IO-Link devices and connect others or the same one again.
Connecting devices to the port is to be considered as an IO-Link start-up.

4.1 Configuration of the process data image
6209
The process data image on the various AS-i transfer options are configured...
- via an acyclic command or
- via a defined default assignment.
The requested mode is selected via the AS-i parameter bit P0.
The IO-Link configuration can be set to the "plug & comm" mode by setting the AS-i parameter bit P2.
In that mode...
- the ports are operated in the scan mode,
- checking of the connected IO-Link devices is deactivated,
- saving parameters is deactivated.

The IO-Link device parameters are always directly changed in the IO-Link device which usually saves
this data non-volatilely.
Deviations between the projected IO-Link configuration (manufacturer, device and function IDs) and
the configuration of the connected devices (with the "plug & comm" mode deactivated) lead to a
peripheral-fault message of the AS-i field module.
If one of these IDs is projected with 0x0000, the configuration of this ID is not checked.
Upcoming alarm events in the device also lead to a peripheral fault message of the AS-i field module.
The type of treatment of unique events must be set beforehand in the service "gateway configuration".
