Great video. Also please clear doubts also. 1. Is the 3 wire communication represents Tx, Rx & Gnd? 2. Is it possible to communicate btw plc and io link with ethernet? 3. Can I use standard sensors with the IO link?
Hi there, Thank you for your questions! For question #1, depending on the manufacturer of the sensor will have its own wiring-type spec sheet. Could be 3 or more wires, but you should always use the data sheet of the sensor. The IO master is responsible to get the information from each device to the PLC. For question #2, PROFINET is based on standard Ethernet for its communication medium, which we discussed in the video. For question #3, for the most part, yes, you can use the standard sensor, but depending on the IO link you use in your design. Again, check the data spec sheet. Here is a link for more learning! www.siemens.com/global/en/products/automation/industrial-communication/io-link.html Happy learning!
Loves this channel. Going to subscribe to the courses in the next few weeks. I'm hoping once i complete everything on their website and obtain all the certificates then i can get a job in automation. ♥️
We're very happy to hear that, Johan! If you have any questions or concerns in the meantime, please do not hesitate to contact us at any time - we're more than happy to help!
Seems like a great cost reduction option for customers. Only limiting factor would be the 20m max distance for the M12 cables. Depending where you instruments are located the 20m might not be enougb to get back to the master
Very helful vedio, im towercrane technician but i need more information ang learn more about plc, you vedio is very helpfull to me, thank you very much
Thanks for making this video. I have a question: do the sensors and actuators need to be specifically designed to work with IO masters or normal sensors and actuators can also be linked to it? thanks in advance
The sensors and actuators used in any I/O strategy need to have the required interfaces built into the sensor or actuator to be able to use the specified I/O hardware protocol. For example, in the video, the sensors and actuators each had IO Link capability built into the devices. They were then able to connect easily to an "I/O block" that "speaks" IO Link on the field side and Profinet on the PLC network side. To answer your question, "normal" 24VDC or 4-20ma sensors and actuators cannot be connected to IO Link blocks, Profinet interfaces or Profibus interfaces because the sensors and actuators do not have the memory or communication structures embedded to provide the data required by these advanced protocols.
You should make a video about OPC UA. I made some proyects to connect Raspberry PI with others embedded devices, sensors, actuators and linked to a DB remotely... but still not with PLC (I don't have but want to buy one). I think it can be a great addition to the channel. Greetings
Really interesting. I've never seen these in the field in process plants. Though there were probably there when I worked in Pharmaceutical Plants on the Manufacturing Lines which had many subsystem PLCs locally and sensors. But at that time I didn't work in Automations just Process Controls at the time. Still very interesting as I didn't know this was a protocol either. I do think i can use one of these for my local PLC Test Bench setup at the office though.
You will be suprised how many there are of these. I was stunned when i first saw them. Then did my research and found out what they were. But ya that always happens, u tend to panic lol
Dear Admin, Thanks for wonderful animated video. I want to know the difference between Profibus, Profinet and Modbus. Can you pls post a session on this topic.?
Thank you RealPars! I wonder what make us move to use the I/O link , in other words , what make it better than using normal wires hooked up to I/O cards! Does using the I/O link substitutes the i/O cards , in other words , it replaces the i/o cards
Hi there, Thank you for your inquiry. Your question is excellent!

What is best way to use an existing 4-20 analog device with an IO link master? Can a signal conditioner be used between the two in order to establish communication?
There are dozens of devices in the market to do this. This is just one example: www.balluff.com/en/de/products/product-news-overview/product-news/io-link-converter-for-analog-in-and-output-signals/. Do a web search for "4-20ma to IO-Link" to see a whole lot more.

IO-Link is a field instrument-level protocol just like Foundation Fieldbus or Asi. However, it is typical for the IO-Link connection block to convert the IO-Link signals, which are typically "short-haul" signals to Ethernet/IP, ProfiBus or some other "long-haul" protocol that can be run longer distances. In this video, the IO-Link connection "bricks" are joined to the PLC network via ProfiNet.
@@realpars Thanks for aswering from the follower to yours. I expect a next video about ASi or about the characteristics of the Fielbus, Devicenet (US), Asi (EU) and this field protocols that I just discovered
What about if I have an optical sensor value that I need to detect soon as happen, can I use I/o Link to manage that signal or it is better to connect directly the signal like digital out. Thank you!
Hello how you guys doing you guys got some awesome videos I don't know how many I have seen but it's a lot. I have one question I have a CNC lathe the drivers are analog AC Servo Motors it's what I was told I look at the papers and it says is analog I bought a new CNC control what do you recommend to change from digital to analog. I would like to use the old drivers is there something like the io link. Some kind of converter from digital to analog if there is what do you recommend thank you keep making good videos
Servo motors typically have specialized drivers provided by the manufacturer of the drive. I would check with them to see if there is a way to use a digital interface to their servo using a converter or gateway device. IO-Link would not be used for drive control, but there are many other digital bus systems, such as Profinet and Ethernet/IP that may be able to be used with proper gateway.
Technically, IO-Link is remote I/O. For "mainline" PLC's like Siemens S7 series or Rockwell Logix, you will need to have a link coupler to tie the IO-Link sensors to the main PLC network (ProfiNet, Profibus, Ethernet/IP, etc).
I am doing 2 projects now that are using both technologies. The price for the interface blocks and cabling are about the same. IO-Link can put information onto ethernet locally using IO-Link master blocks in the field which raise the price of the field bricks but eliminate the need for an ASi master at the PLC or DCS. Overall, each is very easy to design, install, and configure. IO-Link has much richer diagnostics and can handle analogs much better than ASi.
One question please, and i know you would love to answer this. Kindly let me know how did you make this video? I mean the graphics and editing. I can do that but it would take way too much time in flash and other softwares. Please do let me know how! Especially the animation from start till 50 seconds
Hi there, Thanks for your kind compliment, glad to hear that you enjoy our graphics! I am actually not sure about this as this is done by our graphic and animation department.
Thank you for your question! IO-Link uses digital signals to exchange data with sensors. This is less susceptible to noise and more accurate than 4-20mA analog signals. Hope this helps!

Hi Thanks for this wonderful and informative video. I gotta ask that why maximum cable length of IO links is 20m? I connected series of PICV (Pressure Independent Control Valve) to a Siemens KNX thermostat, and my link is exceeded than 20m. Is it a problem?
Every protocol as a standard specification. Maximum cable lengths are determined by the type of signal, the speed of communication, and the electronics used, The biggest consideration is power loss along the length of the cable to a point where reliable communication is no longer guaranteed. For Ethernet, CAT5E, the maximum cable length is specified by IEEE 802.3 as 100 meters. For IO-Link, the maximum cable length is specified as 20 meters. Will a longer cable work? Maybe. Maybe not. Following the standard helps guarantee that you will not encounter signal loss issues. Problems are more likely to occur when an IO-Link junction has multiple devices connected where many of the devices have excessively-long cables.
This module is called an I/O Link Master module. There are many types and versions of these modules (new.siemens.com/global/en/products/automation/systems/industrial/io-systems/simatic-et-200al.html). Typical IO-Link masters in a Siemens system are joined to a Profibus or Profinet network, and I/O or other I/O connection modules are connected to the ports of the IO-Link master.
The cable is usually caller an IO-Lin,k Device Cable. This cable is an unshielded, three or five conductor cables, not longer than twenty meters, using a standard four or five-pin M12 connector. The master and device pin assignment is based on the specifications in IEC 60947-5-2
Correct. IOLink is used for digital and analog transmitters and devices, whereas HART is used pretty much for analog transmitters only. HART does have one distinct advantage, in that it can be implemented using existing analog wiring by upgrading the transmitter and install HART capability at the I/O subsystem.

IO Link is similar to any other node-based protocol. Each device has a unique node number on the segment and has a device description file that identifies the information available from the device. These node numbers are assigned to a device as part of the device's configuration (or DIP Switch selections). A successful hardware configuration in the PLC will contain the node numbers to be used to communicate with the device.
Remote I/O is a general term that is used for a control system architecture where I/O is terminated remotely from (not directly connected to) the CPU rack. IO Link is a specific, simple communication protocol which is for short distance, bi-directional, digital, point-to-point I/O connections. IO Link is an industrial communications protocol that is defined by standard IEC 61131-9. IO Link can be used in a remote I/O architecture for bringing discrete or analog data into the PLC. IO Link requires a communications master and a connection to the PLC network.
IO Link works in the way as Profibus PA. The PLC has a card or other built-in hardware that acts as the IO Link Master. The IO Link nodes each have a unique node number on the bus that is added to the hardware configuration in the PLC. The PLC reserves addresses as each node is built in the hardware configuration, and those addresses can be used in the PLC program. There are tools available that allow some of the device configuration and setup to be done via a graphical software interface.
The I-O Link Master acts more like a DP/PA link coupler, since I/O Link data is transferred to the CPU over Profinet or ProfibusDP in the example in this video. There are also I/O-Link Master cards that fit into the CPU "rack" that are useful when the I/O is close to the CPU. In this video, use of an I-O Link Master is shown in a remote configuration.
It can be done if you install and interface device that converts 4-20ma to IO Link. Example: IFM DP-1213. 4-20ma devices cannot be directly connected to an I/O Link bus without a protocol converter such as described above.
ET200M and ET200SP (as well as other ET200 models) are remote I/O hardware platforms that connect to the PLC network via Profibus DP or Profinet communication protocols. IO Link is a communication protocol, not remote I/O hardware. To use IO Link in a remote I/O strategy, you will need to install I/O blocks (as shown in the video) or other interface hardware to connect field I/O to the PLC network using IO Link.

ET200M and ET200SP (as well as other ET200 models) are remote I/O hardware platforms that connect to the PLC network via Profibus DP or Profinet communication protocols.
IO Link is a communication protocol, not remote I/O hardware. To use IO Link in a remote I/O strategy, you will need to install I/O blocks (as shown in the video) or other interface hardware to connect field I/O to the PLC network using IO Link.
thanks..
You're welcome, Derin!
What about the method of addressing io link
what addressing are you talking about? You put the IO master into the PLC software having the starting adresses.
