Initialize/Setup the BC9000 The following parameterizations can be carried out without using configuration software and with the aid of the DIP switches and the end terminal (KL9010). This parameterization mode is active only if just one end terminal (KL9010) is inserted. Otherwise, the normal settings apply. Restoring the manufacturer's settings Switch off the Bus Coupler, and plug in just the end terminal (KL9010). Set all the DIP switches to ON, and switch the Bus Coupler on again. Once the default parameters have successfully been set, the Error LED lights, and the I/O Run and I/O Error Led's flash alternately. You can then switch the Bus Coupler off, connect the Bus Terminals, and continue as usual. Deleting the boot project (only BC9000) Switch off the Bus Coupler, and plug in just the end terminal (KL9010). Set DIP switches 1 to 9 to ON, DIP switch 10 to OFF, and switch the Bus Coupler on again. Once the boot project has been successfully deleted, the I/O Run and I/O Error Led's flash alternately. "You can then switch the Bus Coupler off, connect the Bus Terminals, and continue as usual. Setting the Ethernet Parameters Switch off the Bus Coupler, and plug in just the end terminal (KL9010). Set all the DIP switches to OFF, and switch the Bus Coupler on again. The I/O RUN and I/O Error Led's light steadily. Make the desired setting in accordance with the following table. DIP Switch Parameters Selection Setting Comment 1 Buad Rate 10 MBaud OFF (0) 100MBaud ON (1) Default 2 Auto-Baud- Disable OFF (0) Rate Enable ON (01) Default 16 April 2008 Beckhoff Application Notes 4
DIP Switch Parameters Selection Setting Comment 3 Transmission Type Half Duplex OFF (0) Full Duplex ON (01) Default To accept the values, set DIP switch 10 to ON. The Bus Coupler indicates that it has accepted the parameters by flashing the I/O RUN and I/O ERR Led's You can then switch the Bus Coupler off, connect the Bus Terminals, and continue as usual.

The following image shows the Device 1 (Virtual-Ethernet) selection: 16 April 2008 Beckhoff Application Notes 6
6. Right click on Device 1 (Virtual-Ethernet) and select Scan Boxes (see image below). 16 April 2008 Beckhoff Application Notes 7
7. Once the selection has been made, TwinCAT will go out and search for all the PLC's on the Ethernet network. In this instance, there is only one (see the image below: 8. Note that the name of the PLC was automatically assigned as BC9000-2 (172.16.17.2). Obviously, the PLC is a BC9000. The -2 at the end identifies the last portion of the Ethernet Node address as Node 2. This is further confirmed with the display of the full Node address of 172.16.17.2. Place a check mark in the box for this PLC and then click OK. 16 April 2008 Beckhoff Application Notes 8
9. System Manager will then look like this: Note the BC9000-2 entry under Device 1-Image. 16 April 2008 Beckhoff Application Notes 9
10. Double click on BC9000-2 to see if all the Bus Terminals have been found, identified, and listed below the BC9000-2 heading. 16 April 2008 Beckhoff Application Notes 10
11. Right-click on BC9000-2 and select Export Variables Info... 12. When you click Export Variable Info..., a Save As window opens. Find the folder to save this project information to, then click Save. The image below illustrates this task.

Once saved, the document will have an "exp" file extension attached. 16 April 2008 Beckhoff Application Notes 11
Note: This "exp" document must be saved with the System Manager file (tsm file extension) as well as the PLC program file (pr6 file extension) in the same folder. The tsm and pr6 files must also have the same names. 13. At this point, everything about the hardware for this PLC is known. At the top left corner of the TwinCAT window, select File and Save As. Find the folder of the previous step and then type in the name for this project. Click Save and this file will be saved as a tsm file. Program the PLC Using TwinCAT PLC Click on the icon in the lower right Windows menu bar (see below) SelectPLC Control. When the TwinCAT PLC Control windowopens, there may be a program already open from a previous effort. If so, go to the File menu and select New. 16 April 2008 Beckhoff Application Notes 12
14. The Choose Target System Typewindow (shown below) will open.select BC via AMS and click OK 15. The New POU window appears to allow for the selection of the name for the new POU, the type of POU, and the Language of the POU. Generally speaking, the first POU should be MAIN as there has to be one POU in the program named MAIN and it must also be a selected as a program. Also, a Language for the POU must be selected. Here, Ladder Diagram (LD) was selected: 16 April 2008 Beckhoff Application Notes 13
16. The main window now appears (TwinCAT PLC Control): 16 April 2008 Beckhoff Application Notes 14
