Dpl Programs

User programs are written for drives and options using a combination of DPL (Drive Programming Language) text, QLD (Quick Ladder) and LD/ FB (Ladder/ Function Block) diagrams.

Only certain node types support user programming. Also, different editors are used to develop the programs for different types of node. This is shown in the following table.

For help on SYPTLite, please consult the SYPTLite help file.

The DPL Editor is used to write programs in offline mode. When online and communicating with targets, the DPL Editor allows programs to be debugged, for example by setting breakpoints and watching the values of program variables and drive parameters. The DPL Editor can manage programs for several nodes at once. While online and communicating with a set of nodes, you can also switch individual DPL programs to editing mode.

When defining the properties of nodes, you can choose to embed DPL program source code (including diagrams) into the user image built from the program and downloaded to the target node. You can also choose whether to embed debugging information in the DPL program. Embedding the source code of a DPL program into the image downloaded to a target means that the original source is always available for upload and modification at a later date. Embedding debugging information enables the debugging (breakpoints, pausing, resuming) of DPL programs while in on-line mode. However, embedding debug information can slow down the execution of a DPL program.

The Beckhoff Remote I/O device does not support DPL programming. However, it is managed by SYPT in order to allow CTNet cyclic data to be defined.

The DPL editor can be opened to edit a user program by double-clicking a node in the Hardware Architure or Link Architecture views of the Configuration Editor or by selecting a node and from the Edit menu, choosing Edit Contents.

In the DPL Editor, you can perform the following tasks when managing DPL programs for nodes:

Creating Programs
Opening and Closing Programs
Saving Programs
Editing Programs
Editing/ Viewing the Properties of Programs
Printing Programs

Creating Programs

When you open the program for a new node, a DPL program is automatically created.

To create a program

1. In the Hardware Architecture or Link Architecture view of the Configuration Editor, select a newly created node.

2. Either double-click the node or from the Edit menu, choose Edit Contents.

The DPL Editor opens displaying the new DPL program. If the program for the node has been previously edited, the existing program will be opened for editing.
