PROFINET Training in South Africa

The IDX Academy ran its second internationally certified PROFINET Engineers course in Johannesburg this last week. Congratulations to the newly certified PROFINET Engineers! The course ran over three days and included a theory and a practical component, and on the third day, two exams. 

The theory covered the basics of PROFINET in terms timing, data exchange, the communication stack, infrastructure, GSDML files, etc., while in the practical, the delegates built a PROFINET Cable, created a PROFINET network, setup a controller using the TIA Portal from Siemens and did network analysis with Wireshark. Tools used in the practical include NETILITIES, ProfiTap Industrial and the Handheld PROFINET Cable Tester which are all from PROCENTEC. 

The delegates will each receive an internationally recognised PROFINET certification and are entitled to claiming 3 CPD points from ECSA for attending the course. Feel free to contact the IDX Academy or PROFIBUS Competence Centre of South Africa if you would like more information on the courses.

PROFIBUS Training in Durban


A little known fact is that the IDX Academy runs certified PROFIBUS training in the Durban area. The training is run according to a schedule and it is best to get your booking in early because space is limited! IDX has teamed up with Cube Technologies, who host the training, making Certified PROFIBUS training even more accessible in the KwaZulu Natal area. 

Who actually presents the course? 
Well it will be a certified trainer from the PROFIBUS Competence Centre of South Africa (run by IDX in Johannesburg), so the course cost is slightly higher than if you were to do the training in Johannesburg (because of the cost travelling of the trainer and equipment shipping), but companies in the area find it a lot more cost effective than if they were to pay for the travelling expenses of sending a delegate to Johannesburg.

Where is Cube Technologies exactly?
Sanyati Park
3 Abrey Road
Kloof
KZN
South Africa

How do I sign up?
Contact Cube at +27 31 764 6081 or visit www.cubetech.co.za, or contact the PROFIBUS Competence Centre at +27 11 548 9977 or visit www.profibuscentre.co.za

What courses are offered?

  • Certified PROFIBUS Engineer’s Course (Earn 5 ECSA CPD points for this course!)
  • Certified PROFIBUS Installer’s Course
  • Certified PROFIBUS Troubleshooting and Maintenance Course
The next courses are running in August 2012 so register today!

How to Configure an Anybus COM Port Transport Path


When configuring an Anybus Gateway device, some of the configurations need to be downloaded using a COM Transport path. Below is a description of how to configure a COM Transport path.

1. When the Transport Path Dialog appears, Select the Serial Tab.


2.Click the "Create" button.


3. Once you click create, you will be presented with the types of transport paths. Select the "COM-Port Transport Provider".


4. You need to give the Transport path a name. If you are planning on using multiple COM ports, make sure the name helps you select the correct COM port when configuring devices (i.e. You could name the transport path "COM 1 Transport Path" so that you know which COM port it is tied to)


5.Once you have named the Path, Select the COM Port.


6. Now that you have configured your Transport Path, you can select OK to download your configuration.


I trust this will help you get your Anybus device configured correctly.

For any questions or comments please feel free to contact us.

How to use the Anybus NetTool for Profibus

This describes the process of using the Anybus NetTool for Profibus so that you don't need any previous knowledge of configuring Profibus networks.

To start you will have to install the Anybus NetTool for Profibus which will come with installation cd included with your Profibus Master device.


1. Once you have installed the NetTool, open it and select "New project"



2. This will bring up a new configuration area that will contain the setup for you Profibus network.



3. The first device you can add to the setup is the Profibus Master. Drag the selected master to the configuration area.



4.To configure the slave you need to have the correct GSD files installed. The GSD file can be found on the device vendors website. 



5. If the GSD file has not been installed click the "Tools" menu option to find the option to add the GSD file to the library.



6. Once the GSD file has been installed, you can find it under the "Profibus DP" library option. Drag the correct file into the configuration area.



7. You can now double click the Master object, which will open the Master properties.




8. Select the Profibus tab and change the relevant Master settings



9. Once you have configured the Master, double click the slave object and set the address to correspond with the slave configured address.



10. Now select the modules under the slave item in the library window and drag all the relevant IO modules into the slave configuration. (Note. Once you have configured the slave, you are able to copy and paste the slave object with all the configured settings, if you have more than one of the same device.)



11. Repeat the process of adding a slave device for any other devices, making sure the address and IO config match what is physically configured on the slaves.


You can now save the project and download it to the Gateway.




 To download the configuration to the Gateway you need to have a Transport path configured. This is basically a connection, either Ethernet or Serial for the config to be downloaded to.

For help configuring the transport path, please see this blog post.

You should now be able to use the NetTool for Profibus to configure your Profibus Master Gateway.

How to configure an AB7629 Gateway

How to configure your Profibus Master to Modbus TCP Slave Gateway?

This seems to be a common question, yet with the amount of time we do it ourselves, we end up forgetting the procedure by the time we receive the next query. So for the sake of all mankind, and our sanity, here is a description of the procedure which will hopefully help you, and help us for the next query...

First things first, go to the link below and make sure you have all of the documents and software installed that it describes. The software you will need is:

  • Anybus IPConfig (this sets up the IP address)
  • Hyperterminal (this configure the gateway IO mapping)
  • NetTool for Profibus Master, which should come on the CD with the device (this configure the Profibus network)

http://anybus.com/support/support.asp?PID=239&ProdType=Anybus%20X-gateway

Hardware that you need:

  • Null modem cable
  • PC with COM port and Ethernet port
  • 24v power supply
  • Profibus RS485 cable with termination plugs (not necessary but helps with testing) 
  • Cup of coffee (not necessary but helps with nerves) 

Once you have installed all the software, you need to make sure you have the GSD files for all the devices you want to control on you Profibus network. These can be found on the vendors websites.

I am Going to setup 2 devices which have the following IO config:

  • 4 bytes input
  • 5 bytes output

Configure Profibus Network

  1. Connect your NULL MODEM COM cable to the Profibus Config port.
  2. To configure the Profibus network you must open the NetTool for Profibus. When adding the devices with their GSD files and adding all the required IO, take note of the amount of bytes being used. For example, if I have 2 devices each with 4 bytes Input and 5 bytes output, my Input max is 8 and my Output max is 10 (you need this info to enable the correct amount of Modbus Registers).
  3. Save your config and download it to the Gateway.
  4. Profibus is now configured.
    (note: Please make sure you have selected the correct COM port when configuring this section, otherwise you will pull your hair out in frustration while the system doesn't work)

Enable Modbus Registers

  1. Connect your  NULL MODEM COM cable to the Gateway Config port.
  2. Open Hyper Terminal and setup the COM port with the following settings.
    Baudrate: 57600 bits/s
    Databits: 8
    Parity: None
    Stop bits: 1
    Flow Control: None
  3. Make sure you are connected and press ESC. This should bring up the menu for the Gateway config.
  4. Select option "6 - Change configuration"
  5. There will be a few settings that come up before the Input and Output register count, continue pressing enter to confirm the settings, or + and - to change the settings.
  6. When you get to Input registers you are going to allocate the amount of registers you want the gateway to expose. These registers are tied to the Read Input Register command on the Modbus Master. For our example I would set this value to 8 bytes.
  7. The next option is the Output registers and again this indicates the amount of output registers you want the gateway to expose. These registers are tied to the Read Holding Register command on the Modbus Master. For our example I would set this value to 10 bytes.
  8. Continue pressing enter until it asks you to save the changes and restart the gateway.
  9. Modbus is now configured
    (note: Please make sure you have selected the correct COM port when configuring this section, otherwise you will pull your hair out in frustration while the system doesn't work)

Setup Network Address

  1. Open the IPConfig tool that you installed from HMS.
  2. This will scan and detect any network enable HMS device. Double click on the device that has been found and set the network address you choose.
  3. You now have an ethernet address you can ping.
    (note: if you have selected an IP range that you are not a part of, you will not be able to ping this device until you set your PC's ethernet address to the same range)

And that's that!

This should now leave you with a fully functioning Gateway that just works! If you have any queries or if the simplicity of this blog is not as simple as I intended it to be, please contact me.
