3.3.5 Communication interface
5130
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].

3.3.6 Operating states
5131
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.
