The module automatically selects the communication speed that matches the IO-Link
device.
IO-Link modus (IOL)
IO-Link communication (C/Q) is activated at pin 4, so an IO-Link device can be con‐
nected.
ISDU (Indexed Service Data Unit) access
The acyclic data allows the device parameters to be written by an IO-Link device or
parameters, measured values and diagnostic data to be read by an IO-Link device.
The following tasks can be performed: • Parameterization/Configuration of an IO-Link
device during operation. • Diagnosis of an IO-Link device by reading out diagnostic
parameters. • Execution of IO-Link port functions. • Saving/Restoring of IO-Link device
parameters. The data on the IO-Link device is uniquely addressed with index and
subindex.
Data storage mode
The data storage mode allows IO-Link devices to be exchanged without any configura‐
tion in the event of service. Both the IO-Link Master and the IO-Link device store the
device parameters. During data storage, these different parameter data memories are
synchronized.
In the event of device replacement, the master writes the stored device parameters
to the new device. The application can be restarted without further intervention via a
configuration tool or the like.
If the IO-Link Master is replaced, the new master reads the IO-Device parameters from
the device and saves them. The “Save and Restore” data storage function must be
activated for this purpose. The application can also be restarted here without further
intervention via a configuration tool or the like.
The data retention mode is only available for devices that comply with IO-Link version
V1.1 and higher.
3.1.2
Dual Talk (IIoT interfaces)
The SIG350 features Dual Talk functionality, which allows the user to address the
module from IT networks and integrate it into Internet-of-Things applications.
The SIG350 contains the following interfaces:
•
MQTT JSON
•
REST API JSON
•
OPC UA
REST API
The Representational State Transfer – Application Programming Interface (REST API) is
a programmable interface that uses HTTP requests for GET and POST data. This allows
access to detailed device information. The format is JSON.
The REST API interface of the SIG350 complies with the JSON Integration for IO-Link
standard version V1.0.0 published by the IO-Link community.
