Starting the Application

At a glance

To work in standard mode, you need to associate defined variables to PDO addresses of the equipment declared on CANopen Bus.

NOTE: For more information on addressing, refer to chapter Data Instances.

Assignment of variables

The table below shows the procedure for direct addressing of variables:

Step	Action
1	In the Project browser and in Variables & FB instances, double-click on Elementary variables.
2	In the Address column, enter the address associated with the variable in the form \Bus.Node\Rack.Module.Channel.Data.
3	Repeat the same procedure for all located variables.

Illustration of assigned variables

The following screen shows the application variables assignment:

Description of variables assignment.

The first four Boolean variables are assigned to the four discrete inputs of the STB DDI 3420 module.
New_Setpoint is assigned to the Lexium 05 control bit. A positive transition of this bit triggers a new positioning.
Target_Reached is assigned to the Lexium 05 status bit which is set to ‘1’ when the target is reached.

CANopen bus wiring

The CANopen bus is connected as follow:

NOTE: The Lexium 05 is at the end of the CANopen Bus. Set the Terminating resistor CAN switch to ‘1’.

The assignment of the pins connectors is as follow:

BMX P34 2010/20102 terminal block description:

Pin number	Symbol	Description
1	-	Reserved
2	CAN_L	CAN_L bus line (Low)
3	CAN_GND	CAN ground
4	-	Reserved
5	Reserved	Optional CAN protection
6	(GND)	Optional ground
7	CAN_H	CAN_H bus line (High)
8	-	Reserved
9	Reserved	CAN external positive supply (optionnal)

Advantys STB configuration

The table below shows the procedure for configuring the Lexium 05:

Step	Action
1	Shut down the STB.
2	Using the rotary switches (located on the front of the CANopen NIM), configure the baud rate. The rotary switches are positionned as followed (5 = 500 kbits/s):
3	Start up then shut down the STB.
4	Using the rotary switches, configure the address of the STB. For example, is the node number of the equiment is ‘54’, the rotary switches are positionned as followed:
5	Start up the STB and press the reset button located on the STB NCO module during for 5 seconds.
6	The STB is configured automatically.

Lexium configuration

The table below shows the procedure for configuring the Lexium 05:

Step	Action
1	Start up the Lexium 05. RDY is displayed on ther interface.
2	Press Enter
3	Press the down arrow key until COM- is displayed. Then press Enter.
4	Press the down arrow key until CoAD (CANopen Address) is displayed. Then press Enter.
5	Using the arrow keys, configure the node number. Then press Esc.
6	Press the down arrow key until CoBD (CANopen Baud Rate) is displayed. Then press Enter.
7	Using the arrow keys, configure the baud rate (500). Then press Esc.
8	Press the Esc until RDY displayed.
