SICK EtherCAT SIG350

MQTT
The MQTT (Message Queuing Telemetry Transport) protocol is an open network protocol
for machine-to-machine communication that enables the transmission of telemetric
data between devices.
An MQTT client is integrated in the SIG350, which enables the device to publish certain
information to an MQTT broker. The format is JSON.
The publication of messages can either take place periodically or be triggered man‐
ually.
The MQTT interface of the SIG350 complies with the JSON Integration for IO-Link
standard version V1.0.0 published by the IO-Link community.
OPC UA
OPC United Architecture (OPC UA) is a platform-independent standard with a service-
oriented architecture for communication in and with industrial automation systems.
The OPC UA standard is based on the client-server principle and enables machines
and devices to communicate horizontally with each other and vertically with the ERP
system or the cloud, regardless of the preferred fieldbus. The SIG350 provides an OPC
UA server at field device level, to which an OPC UA client can connect to exchange
information securely. The interface complies with the IO-Link Companion specification
(version V1.0).
3.1.3 Web interface
The SIG350 has an integrated web interface that provides functions for device configu‐
ration and the display of status and diagnostic information via a web interface. The web
interface provides an overview of the configuration and status of the device.
The graphical user interface ensures fast and intuitive operation.
The prerequisite for using the web interface is the existence of a valid IP address. This
can be set via the rotary switches directly on the device or via the DCP tool. SICK also
offers the SOPAS ET engineering tool, which can be used to configure the SIG350.
In the SIG350, IP addressing is preconfigured to BootP in the delivery state.
After assigning the IP address, enter http:// followed by the IP address, e.g. http://
192.168.0.1, in the address bar of your web browser to access the web interface. If the
device status page is not displayed, check your browser and firewall settings.
