Guide Guide Documentation Various IO-Link products are available from Siemens. Each of these products has a separate documentation. The IO-Link products are embedded in systems, e.g. ET 200SP. The documentation for the system consists of the respective system manual, function manuals and manuals. -
Page 8: System Overview
System overview Introduction A continuous communication down to the lowest field level ensures enhanced use of the functions and performance capability of sensors and actuators. Enhanced use of sensors and actuators allows you to operate your machines and plants more productively. No data other than the actual process value can be exchanged via the standard interfaces (digital, analog) used at the sensor/actuator level. -

Page 10: Io-Link Interface
System overview 2.3 IO-Link interface Example plant with IO-Link The figure below shows an example of plant architecture with IO-Link. Figure 2-1 Plant architecture with IO-Link The IO-Link master establishes the connection between the IO-Link devices and the automation system. If the IO-Link master is a component of the I/O system, it is installed either in the control cabinet or directly in the field as remote I/O in degree of protection IP65/67. - Page 11 System overview 2.3 IO-Link interface Connection system in IP65/67 M12 connectors and other connectors are defined for the connection system in IP65/67; sensors have a 4-pin connector, actuators a 5-pin connector. IO-Link masters are always equipped with a 5-pin M12 socket. The pin assignment according to IEC 60974-5-2 is specified as follows: •...

Page 15: Device Profiles
The structure of the IODD is identical for all devices from all manufacturers. The structure of the IODD is always represented in the identical manner by the IO-Link Configuration Tool of the master manufacturer (for Siemens, S7-PCT). This ensures that the handling is the same for all IO-Link devices regardless of the manufacturer. - Page 16 This means the IO-Link configuration tool supports the transparent representation of the IO- Link system down to field level. Siemens provides S7-PCT for engineering of the IO-Link system. S7-PCT with IODD of a device The following figure shows a section from S7-PCT with IODD of a device and the device information contained therein.
