Getting More Involved

____________________________________________________________________________

Bus identifier is the CAN interface on the MPC5200. CAN0 is the first interface.

Select the tab sheet CAN settings.

SPS-Kit with phyCORE® phyCORE-MPC5200 QuickStart Instructions

Node id is the id of the CAN device connected to the MPC5200. Baud rate is the baud rate with which the connection runs, here it is set to 500kb/s. You can also select Nodeguarding and Emergency telegram if it is supported.

Select the tab sheet Default PDO mapping.

On the right side you can see a predefined Send PDO with two

Index entries. These entries refer to the two Index entries in the Objects list on the left. Both entries are connected to a local

variable in the program PCL_PRG. This means, that every time the variables c and d are updated a PDO is sent with the value of the two variables as data. Click on the PDO 16#1800 entry on the right and press

Properties.

Getting More Involved

____________________________________________________________________________

The COB-ID is the COB that is used for sending the PDO. It consists of an offset and the NodeID configured in the CAN settings tab sheet. Change this value when working with different CAN devices that expects different COB Id´s.

• Change to the tab sheet POUs in the project browser. Double-

click on PCL_PRG. The source code window for this project appears.

The program starts with a call to

CanOpenWriteMSG( wDrvNr:= 0, dwCanID:= 16#70B, ucLen:= 2, bRtrFrame:= TRUE, pPointer8byte:= 0, ucByte1:= 0, ucByte2:= 0 );

Note that you can also send CAN packets directly via a library call.

The parameters are:

SPS-Kit with phyCORE® phyCORE-MPC5200 QuickStart Instructions

wDrvNR: CAN interface dwCanID: COB Id of the packet ucLen: number of data bytes to send bRtr: Remote frame pPointer8byte: ??? ucByte1: first data byte ucByte2: second data byte …

This is used in this example to initialize the CAN device.

The program counts up the two variables c and d. So with every update cycle there will be a packet transmitted with these values.

Click on Project\Build to generate the program.

Debugging

4.3 Visualization

With the CodeSys integrated visualization tool you can draw graphical elements and connect them with your program variables. So the changing of a variable during run-time on the target will change the graphical look of these elements. In this chapter you will learn how to draw a graphical element and to connect it with a variable.

First we will define a Receive PDO that will trigger our visualization object.

Open the PLC Configuration dialog. Click on CANDevice and then on the tab sheet Default PDO mapping. In the drop down box List of mappable objects select Receive. Click on the button Insert Receive PDO. In the Objects list open the first index. Select PLC_PRG.a and click on the >> symbol. The entry is added to the new inserted Receive PDO. Select the newly created index under the Receive PDO and click on Properties.

SPS-Kit with phyCORE® phyCORE-MPC5200 QuickStart Instructions

In the field COB-ID enter NodeID + 512 or any other COB Id your device uses for sending. You have now configured a receive PDO and connected it to the local variable a of the PLC_PRG.

Now we have to draw the visualization screen. Click on the tab sheet Visualization in the project browser. Select Visualizations with the right mouse button. In the popup select Add Object. In the following dialog enter a name for this visualization object, e.g. CanVisu. We now draw a LED on the visualization screen. Click on the

symbol for the circle

and draw a circle on the screen.

Click on the circle with the right mouse button and select Configure. Select Colors and click on the button Inside in Alarm Color. Select red as the fill color. Select Variables and enter PLC_PRG.a in the field Change color.

Close the dialog and save the changes. Click on Project/Rebuild all to compile the project.

Debugging

Start the run-time system on the target if not already running. Press Online/Login and then Online/Start. When you now force your device to send a POD with the specified COB-ID the program copies the data in this packet in variable a. If the variable is greater than zero, the LED should become red.

Please refer to the CoDeSys manual for further information about visualization.

5 Further Information

15 min

This chapter gives you some more informations on how to build your application for running stand-alone and how to write your own drivers and integrate them in the run-time system.

5.1 Running your application without the CoDeSys IDE

When your application is ready for production processes, you can run it as a stand-alone application without the need to have a PC with CoDeSys running. For this to work, you have to create a boot project.

Open CoDeSys and the LED.pro demo if not already open.

If the run-time system on the target isn’t running type in the HyperTerminal

./ppc-plclinux_rt

to start the run-time system.

Press Online/Login Press Online/Run to start the example.

Now you have to create the bootproject.

Press Online/Create Bootproject.

This will automatically copy all necessary files to the target.

Press Online/Logout.

Press File/Exit to close CoDeSys.

Further Information

5.2

Stop the run-time system by pressing CTRL+C in HyperTerminal. Now you can start the run-time system again by typing

./ppc-plclinux_rt

The run-time sytem will now use the boot project files copied from CoDeSys at startup an run the application. The red led on the MPC5200 carrier board is flashing.

Starting the program when booting the target

In this passage you will integrate the created boot project into the start process of the target. When you have finished this part, the run-time sytem will be started automatically each time you are starting the target. With the configurations done in the previous chapter, the run-time system will load and execute the boot project .

The run-time system is startet via the autologin tool that is part of the PHYTEC Linux distribution. You just have to configure the config file for the autologin tool and start the tool via an additional entry in the file inittab

The inittab file describes which processes are started at bootup and during normal operation (e.g. /etc/init.d/boot, /etc/init.d/rc, gettys...). Init distinguishes multiple runlevels, each of which can have its own set of processes that are started.

First you will have to create a start script for the autlogin tool in /etc/sysconfig.

Change the directory to /etc/sysconfig

cd /etc/sysconfig

SPS-Kit with phyCORE® phyCORE-MPC5200 QuickStart Instructions

It is also possible to write your own drivers and dynamically include them in the run-time system. You can find the necessary driver templates and makefile installed on your hard disk in the folder C:\Phytec\SPS-Kit(MPC5200)\RTS\IODrivers. For this to work you’ll need a Linux development system. Please refer to the MPC5200 Linux Kit disc that comes with the SPS Kit. On the disc you’ll find a quickstart instructions that describes how to setup the development system.

For more information on writing own drivers in CoDeSys please refer to the CoDeSys manual.
