What are IO-Link devices?

What are IO-Link devices?

IO-Link is a powerful standard, an increasingly deployed point-to-point serial communication protocol used to communicate with sensors and/or actuators. Extending the globally recognized PLC standard IEC 61131, it allows three types of data to be exchanged – Process data, service data, and events.

What is IO-Link SIO mode?

2.1 SIO mode After start-up the sensor is in SIO mode. In this mode the sensor functions as a normally switching sensor. On the master side the IO-Link port is switched as a normal digital input. The sensor can be used like a standard sensor without IO-Link.

Is IO-Link EtherNet?

The IO-Link Master EtherNet/IP™ (EIP) series combines the benefits of the IO-Link standard with EtherNet/IP™ and Modbus TCP protocols. You can easily integrate the IO-Link Master into an industrial network with existing and new EtherNet/IP™ and Modbus TCP installations using our powerful web interface.

How does an IO card work?

I/O cards function as a bridge between a computer and an outside device – this can range from a monitor to a keyboard. The outside device transmits a signal to the I/O card which results in an action being performed. The part of the I/O card that faces out can accept a variety of different devices and cables.

What is IO-Link Wireless?

IO-Link Wireless is a global mission critical wireless communication standard designed for factory automation based on the IO-Link IEC 61131-9 standard, and defined as a system extension to the already established base technology of IO-Link.

What is an IODD file?

IODD file / PDF The I/O Device Description (IODD) contains details of the information available from the device such as identity, parameters, process data, diagnostic data and communication properties. The IODD is downloaded typically as a . zip file and it contains a . xml file and product photos.

Is IO-Link intrinsically safe?

No, IO-Link is system-constrained to preclude an intrinsically safe signal.

Is IO-Link a fieldbus?

IO-Link is fieldbus independent and can be integrated into all fieldbus systems worldwide. IO-Link relies on standards such as M12, M8 or M5 connectors and three-wire cables. IO-Link is an international standard according to IEC 61131-9.

Who created IO-Link?

Richard Morley
The “father” of the programmable logic controller (PLC), Richard Morley, recently passed away at age 84. After he invented the device 50 years ago, it revolutionized plant floors around the world.

What IO means?

I/O (input/output), pronounced “eye-oh,” describes any operation, program, or device that transfers data to or from a computer. Typical I/O devices are printers, hard disks, keyboards, and mouses.

What is an IO-Link device?

This can also be a “hub” which, as a concentrator, enables the connection of classic switching sensors and actuators. An IO-Link device can be an intelligent sensor, actuator, hub or, due to bidirectional communication, also a mechatronic component, e.g. a gripper or a power supply unit with IO-Link connection.

What are the specifications of the – IO Link community?

What are the modes of the IO-Link ports?

The IO-Link ports of the master can be operated in the following modes: • IO-Link: In “IO-Link” mode, the port is used for IO-Link communication. • DI: In “DI” mode, the port behaves like a digital input.

What is the pin assignment of the IO-Link device?

The pin assignment is specified according to IEC 60974-5-2 as follows: • Pin 1: 24 V • Pin 3: 0 V • Pin 4: Switching and communication line (C/Q) Besides the IO-Link communication, these three pins are also used to supply the device with at least 200 mA (see figure 3). 1 3 5 4 L+ L– C/Q IO-Link SIO 2 Figure 3: Pin assignment of IO-Link device
