Configuration of the PCMCIA TSX CPP 110 Card

At a Glance

Once you have created the EDS files and the CANopen bus using the Sycon software, you must now declare and then configure the TSX CPP 110 card in the PLC.

To declare the card, please refer to the corresponding paragraph in this documentation.

The configuration of the card in this example is shown in the figure below. If you wish to obtain more details concerning the possible configurations, please refer to the corresponding paragraph..

Illustration

The screen below shows the configuration parameters required to implement our example:

Elements and Functions

This table describes the various zones that make up the configuration screen:

Zone	Number	Function
Module	1	This zone comprises the abbreviated title of the PCMCIA card that you declared, which must be a CANopen card.
Channel	2	This zone allows you to select the communication channel to be configured. Click on the channel to obtain the configuration tab.
General parameters	3	In this zone, select the task associated with the I/Os located on the CANopen bus. The selected task will determine the acquisition rate of the inputs and update of the outputs of the CANopen bus slaves. In our case, we will select the master (MAST) task.
Tab	4	The tab in the foreground indicates the type of screen displayed. In our case it is the configuration screen. If you are in online mode, you will be able to access other tabs. In this case, check that you have clicked on the Config. tab to obtain the screen shown in the illustration.
Config	5	This zone is used to select how the bus is to behave at start-up. Select Automatic.
	6	This zone is used to configure the bus. Click on the Control Expert button in order to access the configuration using Control Expert. Select the Demo_cfg.co file that you created with the Sycon software. Result: the bus parameters are displayed when a .CO file is selected. Note: If you modify the .CO file using Sycon, click the Update button in order to reload it into the configuration. Note: If you wish to display the list of slaves on the bus, click the Bus configuration button.
	7	This zone is used to configure the fallback mode for bus device outputs as well as the address (PLC internal memory) where the outputs from CANopen devices will periodically be read. In our example, we select Reset and a number of 32 words starting at the address 50 (%MW50 to %MW81). Later on we will see that these addresses correspond to topological objects (that depend on the slave in which they are located).
	8	This zone is used to activate or deactivate the CANopen bus watchdog. The watchdog is activated by default. It is triggered when the PCMCIA card can no longer manage the bus correctly. When it is triggered, it makes all the slaves’ outputs change to zero. In our example, we will leave it activated.
	9	This zone is used to configure the address (PLC internal memory) to which inputs from the CANopen devices will periodically be copied. In our example, we will retain the default values of 32 and 0 to indicate that the inputs will be stored in the words %MW0 to %MW31. Topological addressing is also available as for the outputs.
	10	This button is used to start the Sycon software, if it is installed on the PC.

WARNING

UNEXPECTED APPLICATION BEHAVIOR

Before deactivating the watchdog, ensure that, if the PCMCIA card does not manage the CANOpen bus, then the devices behavior remain acceptable.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Confirmation and Generation

Once you have completed the different fields in the configuration screen, you must:

confirm the configuration
generate the project.

When these two operations have been carried out, you can save your .STU file and transfer your project to the PLC.

I/O Distribution

The inputs and outputs configurated in the .CO file are distributed in the following manner:

%MW0 contains inputs for node 2.
%MW50 contains outputs for node 2.
%MW1 to %MW5 contain inputs for node 3.
%MW51 to %MW53 contain outputs for node 3.

I/O Topological Distribution

If you click the Bus configuration button in the configuration screen, you can display the two CANopen bus nodes and thus obtain the I/O topological addressing.

For node 2, we have the following inputs:

%IW\3.2\0.0.0.0 which corresponds to %MW0.

and the following outputs:

%QW\3.2\0.0.0.0 which corresponds to %MW50.

For node 3, we have the following inputs:

%IW\3.3\0.0.0.0 which corresponds to %MW1,
%IW\3.3\0.0.0.1 which corresponds to %MW2,
%IW\3.3\0.0.0.2 which corresponds to %MW3,
%IW\3.3\0.0.0.3 which corresponds to %MW4,
%IW\3.3\0.0.0.4 which corresponds to %MW5.

and the following outputs:

%QW\3.3\0.0.0.0 which corresponds to %MW51,
%QW\3.3\0.0.0.1 which corresponds to %MW52,
%QW\3.3\0.0.0.2 which corresponds to %MW53.
