SICK EtherCAT SIG350

3 Product description
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 EtherCAT. 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 EtherCAT 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 IO-Link
IO-Link is a standard (IEC 61131-9) that can be used to connect intelligent devices at
the sensor and actuator level to an automation system.
The SIG350 complies with IO-Link specification V1.1.3.
Communication
Communication takes place between a master and a device. An IO-Link Master con‐
tains one or more ports. One device can be connected per port, which means that
IO-Link is point-to-point communication and not a fieldbus. The IO-Link Master forms
the interface between the higher-level fieldbus level and the IO-Link system.
IO-Link is functional and enables advanced diagnostics of sensors and actuators or
simple and fast parameterization through bidirectional communication. The IO-Link
devices are connected to the master via unshielded 3-, 4- or 5-wire standard cables of
a maximum length of 20 m.
The SIG350 supports IO-Link communication at the following speeds:
