3.1 General information
The SIG350 IO-Link Master is a gateway for connecting IO-Link devices as well input
and/or output signals for data integration into a PLC via EtherNet/IP . Parallel to the
fieldbus communication, the data can also be transmitted to a network via the inte‐
grated IIOT interfaces (REST API, MQTT or OPC UA). It is intended for use in industrial
environments that require enclosure rating up to IP67.
The module has eight IO-Link Master channels and eight universal digital channels
(PNP). The device is connected to an M12 female connector that can be operated
either in the Class A or Class B connection type.
In addition, the SIG350 has a powerful user interface that can be accessed either using
the SOPAS ET software from SICK or directly via the web interface. This is used to
parameterize the SIG350 and the connected devices.
The SIG350 can be commissioned using the following methods
•
Engineering tool of the PLC manufacturer
•
Integrated web interface
•
SICK SOPAS Engineering Tool application
•
Dual Talk interface
Parameterization
•
Parameterization via EtherNet/IP is performed using the engineering tool of the
PLC manufacturer to access the SIG350 directly. Depending on which type of
PLC engineering tool is used, parameterization of the SIG350 and the connected
devices is done in different ways.
•
The integrated web interface of the SIG350 provides direct access for parameter‐
ization via a suitable web interface on devices connected to the same Ethernet
network as the SIG350.
•
It is also possible to connect the SIG350 to the SOPAS Engineering Tool from SICK
via Ethernet for parameterization. The SOPAS Engineering Tool application can be
downloaded at www.sick.com.
•
The SIG350 also has different IIoT interfaces (Dual Talk) that provide direct access
for higher-level automation operations.
3.1.1 EtherNet/IP
The Profinet technology was developed by Siemens and the member companies of the
Profibus user organization. EtherNet/IP based on Ethernet-TCP/IP. Profinet can be used
to implement solutions for manufacturing technology, process automation, building
automation as well as for the entire spectrum of drive technology up to synchronous
motion control applications. Profinet is an open communication protocol according to
IEC 61784.
The SIG350 supports PROFINET specification 2.41 and follows the guideline “IO-Link
Integration – Edition 2 Specification for PROFINET Version 1.1 – February 2020 Order
No.: 2.832.”
Requested Packet Interval (RPI)
The PROFINET concept has a modular structure. Data is exchanged between the con‐
troller, also called the IO controller, and the connected participants, the IO devices, by
means of Ethernet telegrams. The devices exchange data cyclically according to the pro‐
vider-consumer principle. The devices operate simultaneously as receiver (consumer)
