Beckhoff TwinCAT 8

Setting up CX9000

Add Route DialogAt default the CX9000 is addressed via DHCP therefore under the address info make sure the Host name is selected and not the IP Address. If you cannot find the CX this way make sure that your network settings are DHCP as well and that a cross over Ethernet cable is used.

Beckhoff TwinCAT 9

Setting up CX9000

Add Route DialogClick on the desired CX and click Add route. AS you can see the CX`s name is CX_01DA18. If you look at the CX`s MAC ID the last 6 digits are the last six digits of the CX. Therefore the last six digits of this CX`s Mac ID is 01-DA-18.

Logon InformationDefault User name is Administrator.

Default Password is kept blank

For CX10** and other embedded PC`s and Industrial PC`s the default Username is administrator. The Password is 1.

Beckhoff TwinCAT 11

Setting up CX9000

Add Route DialogOnce you have accepted the Username and Password you should get a “X” under the Connected. This means Twincat and the system manager now has a route to connect to the device.

Beckhoff TwinCAT 12

Setting up CX9000

Choose Target SystemLook for the CX that you have just connected to and click on it. It will highlight like on the left. You can then click “OK”

Beckhoff TwinCAT 13

Setting up CX9000

Now ConnectedAs you can now see at the top of the System manager the name of the device connected is showing. Also on the bottom right side is the status of Twincat on the CX and the CX connected in red.

Beckhoff TwinCAT 14

Setting up CX9000

Change CX AddressNow you will have an extra tab called “CX Settings”. Click on this and then you will be able to give the CX an address of your choice.

Beckhoff TwinCAT 15

Setting up CX9000

Change CX AddressChange the IP Address to 172.16.17.90.

Change the Subnet mask to 255.255.0.0

Click apply.

Default address for BC9000 couplers is 172.16.17.(*Dip switch*)

Beckhoff TwinCAT 17

Setting up CX9000

Internet Protocol PropertiesChange your Networks IP address. You can use any range from 1 – 255. Better to Disconnect your network cable when changing IP addresses.

I have addressed it 172.16.17.1

Click ok.

You will now be able to ping the CX using this range.

Beckhoff TwinCAT 18

Setting up CX9000

Choose Target SystemNow back to the Choose Target System. Since we have changed the address we must now link the CX again with the new Address.

Beckhoff TwinCAT 19

Setting up CX9000

Add Route DialogAs you can see the connected “X” has gone again. The address has changed.

Click the IP Address option next to the Host Name and Add Route.

Once again. The Username and Password is asked.

Click ok and you will now see the system is connected again with the new IP range

Restarting system in Config ModeConfig mode allows you to monitor and scan the bus.

Click the Blue button at the top of the system manager.

Click the “OK” button.

Now your CX is in config mode.

Scanning of IOClick “Yes” to scan for all boxes.

Click “Yes” do create corresponding device for the Ethercat PRofibus Master.

Do not activate free run. Free run is used when you want to force outputs when in config mode.

Your Scan tree should look similar to this

Twincat Programming – Choose a Run Time SystemChoose the run time system that is your CX. This will now connect the Twincat program to the CX so that when you download, the program will be downloaded into the CX.

If you look at your bottom left hand corner you will see a target and if the system is Running. This does not mean that the system is in Run mode however.

Twincat Programming - Save

Save your program in a specific location. This is important and remember where you have saved it as the system manager reads a *.tpy file in the folder where the plc program has been saved.

Connecting Twincat Program to System managerGo back to the system manager. Click on PLC – Configuration.

Right click and Click on “Append PLC Project…”

Search for you File *.tpy file which is saved in the directory that you saved your program. If you move your program and rebuild it this file will not be updated. You will have to search for the new *.tpy file created in the directory where you moved the program.

Beckhoff TwinCAT 35

Setting up CX9000

Program Connected To System ManagerNow the program is connected. As you can see the program can be rescanned. This is for when extra variables have been added to your program. You can set this to automatic by clicking “Options” and tick “Check PLC project changes”.
