The library can retrieve information about projects and applications as well as area addresses and sizes of data types. Retain variables can be stored in files and it is possible to start, stop and reset an application from within another one. More information AppAreas: Different kinds of data like retain, input, output etc. are stored in certain areas of the PLC. The addresses and sizes of each are retrieved. Depending on the PLC an area can handle different kinds of data. AppInfo: To get information about an application, the respective one must be retrieved first. One way to get a specific application is to sequentially go through all applications, starting with the first. Another way is to fetch the current application or retrieve one by its specific name. On the basis of this, additional information about applications and the projects can be retrieved. AppInteract: Different actions like start, stop and reset can be controlled within a program. To demonstrate this, App2 will be controlled by App1. AppRetain: Retain variables can be saved and restored from a file. To restore them, the Pointer to the application must be identical to the one the data was stored with. ExceptionDuring_InitCode: An exception is generated in the FB_Init method of this function block. When the FB is instantiated this exception is thrown and no code can be downloaded to the PLC.

Path3D is designed to be used in combination with CODESYS SoftMotion (see the CNC 3D Editor example). However, this example shows the application of it independently from CODESYS SoftMotion. Product description A path with 2200 points in the shape of a gate is created in this example. The generated path is visualized in yellow. Parts of the path are highlighted in red, by setting the member variable udiSourceElementID of VisuStruct3DPathPoint and the visualization property Highlighting variable. The track is calculated from the points of the path. The data structure ‘VisuStruct3DTrack’ of System_VisuElem3DPath.library is used for hosting the points of the path and the track. More information PLC_PRG: The main program of this example instantiates an element of VisuStruct3DControl for navigating in the 3D model. It also creates an instance of PathGenerator (FB) that generates the path and calculates the track. Both structure instances are linked with the appropriate visualization element. PathGenerator(FB): This function block first creates a path of 2200 points. Afterwards, the track, which moves along the path, is calculated with the help of a ring buffer. That means, when the buffer is full, the next point will be saved at the beginning and the starting point will be incremented by one and so on. Visualization: The visualization object Path3D uses the information of the VisuStruct3DTrack elements ‘Path’ and ‘Track’ and the instance of VisuStruct3DControl for the 3D model. In the Path3D Properties the color of the path and the track can be changed. Also the color for highlighting specially elements of the path can be chosen.

Another example shows how to read and write SDO"s with CAN over EtherCAT as well as downloading a firmware file with File over EtherCAT. Product description ServoDrive over EtherCAT This example shows how to read and write IDN"s with ServoDrive over EtherCAT. As hardware a Rexroth IndraDrive is used. It is also possible to switch the device to another one which uses ServoDrive over EtherCAT. Several startup parameters can be set as device configuration. These parameters are called IDN"s for devices using ServoDrive over EtherCAT. For each IDN the name, attribute, unit, minimum, maximum and value can be set as number or byte array with a maximum of four bytes. File over EtherCAT This example shows how to read and write SDO"s with CAN over EtherCAT as well as downloading a firmware file with File over EtherCAT. It is also demonstrated how to get information about the master and slaves, like the number of active slaves or the state of the slave. As hardware two analog terminals with CAN over EtherCAT are used. The File over EtherCAT functions are implemented theoretically, without hardware. For device configuration several startup parameters can be set. For devices which use CAN over EtherCAT an index and sub index is used for each parameter. For each parameter it is possible to read or write the value as number or byte array with a maximum of four bytes. More information ServoDrive over EtherCAT Several startup parameters can be set as device configuration. These parameters are called IDN"s for devices using ServoDrive over EtherCAT. For each IDN the name, attribute, unit, minimum, maximum and value can be set as number or byte array with a maximum of four bytes. Two startup parameters are already set at the beginning. Look at the "startup parameters" tab on the device. The "slave" tab shows the EtherCAT address which is used to select the device. In the "EtherCAT_Master" device under the "Master" tab the correct source address, where the device is connected must be set. SoE: First the program has to wait for the EtherCAT master to be ready. Afterwards the IDN number 32 is read from device 1001 which was already set at startup. Additionally an IDN is written to the device and afterwards it is read again once as UINT value and as byte array. It is possible to read the name, attribute, unit, minimum, maximum and value of an IDN. Use the specific value at "byElem" for that. The "byDrive"value is not set, because the used device only has one. The index of the EtherCAT master is set at "usiCom" and the address in "uiDevice". Depending on the device, the timeout must be set high enough. File over EtherCAT For device configuration several startup parameters can be set. For devices which use CAN over EtherCAT an index and sub index is used for each parameter. For each parameter it is possible to read or write the value as number or byte array with a maximum of four bytes. Parameters for EL4132 and EL3142 are set before startup. By double click on one of these devices the "Startup parameters" tab is shown. One is already set and with the "New" button, more can be selected. The "Slave" tab shows the EtherCAT address which is later used for selecting the device. In the "EtherCAT_Master" device under the "Master" tab the correct source address, where the device is connected must be set. CoE: First the program has to wait for the EtherCAT master to be ready. Afterwards the parameter from device 1002 which is already set is read in a byte array and as dword. Additionally a parameter of four bytes is written and read afterwards. A parameter larger than four bytes is also written in this example. So far only the parameter values are used, but it is also possible to read the complete entry into a byte array. These values are device specific. All function blocks contain an "udiSdoAbort" variable. If an operation is canceled, this variable returns an abort code. The error to this code can be found in the CANOpen Spec. FoE: This function demonstrates a way how to download a fictional firmware with File over EtherCAT. After the EtherCAT master is ready, memory for the complete firmware will be allocated. Then the specific slave is set to boot mode to download the firmware. When the download is finished, the memory will be released. The upload function has no direct relation to the firmware example it shall only demonstrate how the instance is called.

Synchronous and asynchronous function calls are used. Product description Several functions for file management are demonstrated here, such as creating files and directories, renaming, deleting and copying them as well as reading and writing files. A directory can be browsed to find all included files. In the synchronous way, the function will wait until a result is returned. Sometimes this lasts longer than one cycle. There for an asynchronous call can be used. Here the function will not wait for a result. At each call the function will ask again for a result, when it is available the variable xDone is set to true, otherwise it stays false until a result is available. More information SystemDir: Several synchronous functions are used to create a directory. The directory is browsed to find all included files. After renaming, the directory will be deleted. SystemFile: Several synchronous functions for file modification are used. First the file is opened with write access. A string is written to the file and it will be closed after. The next step opens the file again and reads the written string. After copying the file a new string is appended at the end. Some file information like creation time and size are retrieved as well. CAA_Dir: It shows how to create, open, close rename, browse and remove a directory. This is done in an asynchronous way with use of a state machine. When the function block is done or sends an error, the Next or Error state is reached. CAA_File: This program does some file modification in an asynchronous way. After opening the file a string is written into that file and later read again. File information are fetched as well as appending another string into the file.
