Mining Application Using IO-Link Master and PC

Mining Application

A North American mining systems integrator implemented a solution for a mining company seeking a better way to identify particle size and increase awareness of jams on their mineral mineral fragmentation conveyor line.

Comtrol’s IO-Link Master 4-EIP, with the IO-Link laser distance sensor connected, helped them achieve both of these tasks. The main reasons they decided to use Comtrol’s IO-Link master were:

  • Comtrol’s master is able to work directly with a PC, no PLC required
  • Other IO-Link master solutions rely on a PLC to use and set up the master, which was not desired for this application
  • The ease of set-up, powerful web interface and Modbus TCP support were other determining factors.

The end-user was using a vision system for analyzing mineral fragmentation on a conveyor line. The mineral would be broken down and sent along the line where the vision system would ensure the particle size was correct.

However, problems exist with picking up accurate readings when the bed depth, or amount of mineral on the line, is great. Working with Comtrol’s IO-Link Master that is used to connect the IO-Link distance sensor has helped the company increase their accuracy with reading the bed depth. The laser distance sensor is also used to pick up the distance to the top layer of mineral going down the line which helps normalize the data along with the vision system. This improves accuracy in analyzing mineral particle sizes as the line moves along.

Access Control UL294/294B Regulations: Why Do They Matter?

UL294 is the standard of safety for Access Control System units that all access control systems must meet. UL294B is a newer standard, specifically for the use of Power over Ethernet (PoE) components used within access control systems where PoE is the primary power source.

Government and state regulations are moving toward required UL294 compliance. Comtrol’s RocketLinx ACS7106 is the first UL294B certified switch enabling confidence in deployment and integration within access control systems. 

The ACS7106 switch features four 10/100BASE-TX PoE Plus ports for providing power and data to remote PDs (Powered Devices) such as access card readers and IP surveillance cameras, and two 10/100/1000BASE-TX uplink ports that assure maximum throughput for high bandwidth applications.


The official site for the UL Standards states that:

SCOPE (UL294)

1.1 These requirements apply to the construction, performance, and operation of systems intended to regulate or control:

a)    Entry into a protected area or a restricted area or

b)    Access to or the use of a device(s) by electrical, electronic or mechanical means.

Meeting Your Network Needs: Unmanaged vs. Managed Switches Explained

The world is moving towards managed switches as complexity and demand increases. But what are the differences and how do you know which switch is right for you?Unmanaged vs. Managed Switches Explained RocketLinx_group 3_left

An unmanaged switch reduces costs and simplifies the configuration process. On the other side, a managed switch is more intelligent, allows for new technology and application adjustments, as well as enabling better troubleshooting and most importantly increased security.

An unmanaged switch is less expensive at initial purchase. An unmanaged switch contains a fixed set of rules and will handle incoming data based on those rules. It’s important to note that the forwarding rules cannot be changed, which may increase downtime to discover and fix a problem. An unmanaged switch can simplify the configuration process or decrease the product cost in some of these areas; a less powerful processor, may contain less memory, fewer LEDs, fewer ports. Depending on your network needs those cost saving efforts can greatly benefit your company.

The best feature of a managed switch is its configurability. When using a managed switch you are free to adjust the rules for your application at any time, this can be very useful in the Industrial Automation field and many others. The configurability can save costs and downtime when you are free to separate your networks.  The best way to benefit from this configurability would be to have an engineer in your company who understands the managed switch’s complexity. A managed switch offers other valuable resources such as; the support of VLANs, IGMP snooping, port mirroring, decreased downtime and increased security.

Comtrol offers a wide selection of industrial, enterprise, and hardened switches supporting 10/100/1000 Ethernet, fiber, and PoE applications.  The end decision of a managed or unmanaged switch will be determined by your unique network needs.

Tech Tip: DTE and DCE

DTE, short for Data Terminal Equipment is a device that controls data flowing to or from a computer. The term is most often used in reference to serial communications defined by the RS-232C standard. This standard defines the two ends of the communications channel as being a DTE, and a DCE device. In practical terms, the DCE is usually a modem and the DTE is the computer itself, or more precisely, the computer’s UART chip.

Comtrol serial ports are DTE devices except for products which have been specifically designed to be switchable from DTE to DCE.

Connecting:

When connecting a DTE device to another DTE device it is necessary to use a Null Modem cable.

When connecting a DTE device to a DCE device it is necessary to use a Straight Thru cable.

IO-Link 101: 10 Terms to Know

1. IO-Link System

An IO-Link system is comprised of sensors and/or actuators that support IO-Link (version 1.0 or 1.1) which are connected via a master, such as Comtrol offers. The master then will communicate to a controller (PLC, HMI, SCADA, etc.) through an industrial Ethernet protocol such as Ethernet/IP, Profinet IO or Modbus TCP.IO-Linksimultaneous

Full Explanation

2. MultiLink – Comtrol Specific Benefit

MultiLink provides the capability to simultaneously access multiple IO-Link controllers running different industrial Ethernet protocols.

Full Explanation

3. IODD: IO Device Description

Every IO-Link sensor/actuator has an IODD file which allows you to interact with the device on a web interface such as Comtrol’s. Each IO-Link device manufacturer will have these available via their website. With Comtrol’s IO-Link Master you can load and store a library (up to 15790K) of IODD files for your IO-Link devices onto the Comtrol IO-Link Master so that you can configure the IO-Link sensors or actuators from the IO-Link Master web interface.
