Paint Spraying Operation Integrates IO-Link

Posted by


A furniture manufacturer was in need of a time and money saving solution. This company needed something that could identify the size of sections of furniture on the paint spraying line and thus reduce over-spraying and wasting paint. Leuze’s CML720i light curtains that were IO-Link enabled were chosen to accurately measure piece dimensions. They also needed an IO-Link master block that could handle the power requirements and effectively communicate with the PLC.

The CML720i light curtains are positioned at the entrance of a paint powder coating machine which tell the automated paint guns when to spray and when to turn off, based on the size of the piece moving through. Before this solution, spray guns would turn on well before a piece arrived and remained on well after, which over time wastes a large amount of paint. They also wanted to avoid spraying the hooks connected to the conveyor system which guided the pieces through the painting machine. All of this information is communicated to a PLC running on EtherNet/IP via the Comtrol IO-Link master 8-EIP.

By using Leuze’s CML720i light curtains that are IO-Link version 1.1 devices, they are able to save parameters set for the CML720i light curtains right in the Comtrol IO-Link master by using an IO-Link feature called Data Storage. This allows the customer to easily replace a CML720i light curtain and automatically upload the previously saved settings to the newly connected curtain. This eliminates the need to configure the device from the default state.

Comtrol was able to meet the needs of this application in a number of ways. The IO-Link Master 8-EIP supports high power current support, including 1.6 amps on port #1, which is required to operate the large CML720i light curtains. The IO-Link Master also provides power overload protection. If a device is connected that is attempting to pull more power than can be provided, the IO-Link Master will shut down that port once a certain threshold is exceeded. When the power draw subsides, the port will re-activate. In addition, the powerful web-interface provides the customer will multiple benefits that most master blocks do not.

For example, the web-interface allows the user to:

  • Save IODD files in a library
  • Utilize data storage
  • Change the parameters of a device right in the web-page
  • Use device validation to allow a specific device to work on a specified port
  • Configure ports to operate as an IO-Link port, Digital Input or Digital Output
  • Look at PLC diagnostics

Material Handling with IO-Link

Posted by

Material Handling

Material Handling with IO-LinkA large industrial supplier in the Midwestern U.S. uses small and large plastic totes to transport material throughout their factory. As these totes move along the line, there are designated locations where they are empty and need to be stacked, but often times these totes entered the stacking area with material left inside, which caused the stacker machine to jam. To prevent this from continuing, the industrial supplier turned to a systems integrator and Comtrol’s IO-Link Master.

Due to its simple installation, the system integrator opted to use Comtrol’s IO Link Master DR-8-EIP to control Leuze Electronic IO-Link enabled light curtains and laser distance measuring sensors. With this implementation, the light curtains determine how the totes are stacked while the laser distance measuring devices scan for contents inside the totes.

The IO-Link Master DR-8-EIP offers eight IO-Link ports, two dedicated Digital Input/Digital Output ports, and ten Digital Input ports. With this configuration, the IO-Link Master allows the flexibility to support up to 20 device connections.

Improve Diagnostics and Reduce Wiring for Sensors and Actuators with IO-Link

Posted by

IO-Link Technology

IO-Link, the first standardized IO technology for communication with sensors and actuators, is a powerful point-to-point communication based on the long established 3-wire sensor and actuator connection. In addition to working smoothly in any control system, IO Link encompasses features that give you better diagnostics and can reduce wiring for your devices.

IO-Link mobile diagnostics

IO Link gateways allow you to connect multiple smart devices via one IP address, saving you time and money in installation time.

With IO-Link, you can reduce the time needed to fix a broken sensor. Say a sensor fails. If you have a large control system, it may take a while for that sensor to be found. Then when it is found, it may be difficult to reach. IO-Link gives you all the information you need to find and fix that sensor, including diagnostics of the process control system, remote programming, and even custom replacements that can be done automatically. Comtrol’s IO-Link Masters provide diagnostics about both sides of a given connection; you will get information about the IO Link connection that is running from the IO-link master to the end device and you will get detailed information about the industrial data protocol.

The ability to do remote parameterization can be combined with the support for remote diagnostics. Troubleshooting and fixing problems with a system can all be done remotely. Additionally, for those processes or systems where a “recipe” architecture is appropriate, IO-Link sensors and actuators can be remotely parameterized by the PLC in bulk via a simple selector switch or other minimal operator action. This powerful feature could be used to maximize quality or increase duty cycle via extended capital versatility without the burden of re-configuring each device one at a time.

IO Link is the further development of the existing, tried-and-tested connection technology for sensors and actuators, which can be easily integrated into a system network with existing and new industrial Ethernet installations. Come and see why you should implement IO Link in your system today.

IO-Link Competency Centers

With increased developments in IO-Link technology, the need for Competency Centers has grown from locations in Germany and the Czech Republic to the USA.  The designated Competency Centers are labs in which technical expertise and support are available and offered to IO-Link manufacturers and vendors.

IO-Link Competency Center

What is IO-Link?

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. Major sensor manufacturers and industrial manufacturing companies, including Comtrol, have joined the international IO-Link Consortium to promote the IO-Link communication protocol due to its many advantages over standard I/O.

Comtrol’s IO-Link Master EIP-4 – ISDU Handling

IO-Link Master EIP-4In case you missed it, we recently published a post explaining IO-Link technology along with an overview of our IO-Link Master EIP-4 product.  As more people learn about the benefits of IO-Link, the more questions we get about our master’s features. Here are some of the features explained below.

One of the features explained is how Comtrol’s IO-Link Master EIP-4 eliminates complex and lengthy PLC programming for process data and ISDU handling (sometimes known as SPDU).

The Comtrol IO-Link Master provides a flexible and simplified ISDU interface with the following features:

  • Multiple or single ISDU command message support
  • Blocking and non-blocking messaging methods
  • Flexible PLC ISDU message formatting – each message can contain a single command, multiple commands with the same data area size, or multiple commands with varying data area sizes

What is IO-Link?

What is IO-Link?Comtrol recently debuted its IO-Link Master EIP-4 at SPS IPC DRIVES in Nürnberg, Germany, and the demo and show were a success! The IO-Link master EIP-4 combines the benefits of the IO-Link standard with the EtherNet/IP and Modbus TCP protocols.  The IO-Link Master effectively shields the PLC programmers from the IO-Link complexities by handling those complexities itself.  The result is simplified EtherNet/IP and Modbus TCP interfaces, which decreases system development time and installation efforts.

Industrial Ethernet Book has named Comtrol’s IO-Link Master one of the Top 5 New Products 2012 in their December issue of Industrial Networks News!

Comtrol is part of the IO-Link consortium, which has created a goal to “develop and market IO-Link as a technology.” This video helps explain, “What is IO-Link?”
