Introduction
2 Introduction
2.1Function overview
Project structure
The project is saved in a file that is named after the project.
The first organization unit created in the new project is automatically called PLC_PRG. Other organization units (programs, function blocks and functions) can be called from here.
The DDS uses the Object Organizer to differentiate between the different object types within a project:
•Organization units
•Data types
•Visualization elements (visualization)
•Resources.
The Object Organizer allows fast access to all objects of your project. Resource structuring uses the following objects, among others:
•Libraries
•Codes
•Task configurations
•etc.
Project generation
Addresses not included in the PLC configuration cannot be used.
First configure the control to facilitate access to the system organization units during programming.
Then generate the organization units required for your application, or copy them from existing projects. Program the required organization units in the desired language.
On completion of the programming process, compile the project and eliminate any reported errors.
Simulation with the DDS
Once all errors have been eliminated, activate the simulation, log in to the simulated control and start the project. The DDS is now in online mode.
The window with the PLC configuration can now be opened, and the project can be checked for correct operation. For this purpose, assign the inputs manually and check that the outputs are set as required. The organization units also allow a monitoring of local variable current values. Use the Watch and Receipt Manager to configure the data records to be monitored.
Note!
Lenze function blocks are not simulated.
Simulation is generally restricted. ( 6-37)
Debugging with the DDS
In the event of a programming error, breakpoints can be set. If program execution stops at a breakpoint, the values of all project variables as at that time can be inspected. Logical correctness of the program can be checked by step-by-step processing (single-stepping).
Program variables and inputs / outputs can be set to specific values.
Project documentation using the DDS
The entire project can be documented or exported to a text file at any time.

Introduction
2.2Project components
2.2.1Project
A project includes all objects of a control program. Links with the libraries are saved in a file bearing the project name.
A project includes the following objects that can be accessed via the Object Organizer:
•Organization units
•Data types
•Visualizations
•Resources
–Libraries
–Codes
2.2.2Organization unit (POU)
Functions, function blocks and programs are organization units of a project and referred to as program organization units (POU) in the
IEC 61131 programming language.
Every organization unit consists of a declaration part and a body. The body is written in one of the IEC programming languages (IL, ST, SFC, FBD, LD or CFC).
The DDS supports all IEC standard organization units as well as Lenze-specific organization units. Use of these organization units in your project requires the associated function library to be linked to your project with the help of the Library Manager.
Organization units can call other organization units. Recursions cause a compiler error and must be avoided.
2.2.3Function
A function is a software organization unit that returns exactly one data element (that may also consist of several elements such as fields or structures, for example)on execution and whose call may occur in textual languages as an operator in expressions.
Note when declaring a function that a type must be assigned to the function, i.e. the function name must be followed by a colon plus type.
The names of function and function output are identical.
Example of a correct function declaration:
FUNCTION Fct: INT
•A function declaration starts with the keyword FUNCTION.
•A result must be assigned to the function, i.e. the function name is used like an output variable.
•In ST, a function call may occur as an operand in expressions.
•Functions cannot save their internal statuses. Function calls using the same input parameters always return the same value.
•No functions can be programmed in SFC.

Introduction
Function CheckBounds
Tip!
Definition of a function with the name CheckBounds in your project will automatically check whether the boundaries have been exceeded on access to an array in your project! (refer example below).
Also refer the Checkbound library (Checkbound.lib).
The function name is defined and must not be changed.
The following program example to test the CheckBounds function corrects access outside defined array boundaries.
The function CheckBounds ensures that the value TRUE is not assigned to position A[10], but to the upper permissible range limit A[7].
Use the function CheckBounds to correct accesses outside array boundaries.

Introduction
2.2.4Function block
A function block is a software organization unit whose execution returns one or several values.
•Unlike a function, a function block does not supply a return value.
•A function block declaration starts with the keyword FUNCTION_BLOCK.
•The creation of instances (data records) of a function block is a prerequisite.
2.2.4.1Function block instances
•Every instance has its own identifier (instance name) and a data structure which includes its inputs, outputs and internal variables.
•Instances are locally or globally declared like variables by giving the function block name as identifier type.
Example of an instance named INSTANZ of function block FUB:
INSTANZ: FUB;
•The instances described above are always used to call function blocks.
•Only input and output parameters can be accessed from outside an instance of a function block, not its internal variables.
Example with the help of a data model:
Instances L_ABS1 ... L_ABSn are instances of the function block type L_ABS. Instance as many instances as required.

Introduction
Example of access to an input variable:
(* The function block fb has an input variable in1 of type int. *) PROGRAM prog
VAR inst1:fb; END_VAR LD 17
ST inst1.in1 CAL inst1 END_PROGRAM
•The declaration parts of function blocks and programs may contain instance declarations. Instance declarations are not allowed in functions. A function cannot call a function block.
•Access to the instance of a function block is restricted to the organization unit in which it was instanced, unless it was globally declared. Function blocks should never be globally declared as this would lead to logical errors.
•The instance name of a function block may be used as input for a function or a function block.

Counter is the instance name of function block L_IOParCounterModule and can be |
|
|
used as input in the code. |
Note!
All values remain the same from one execution of the function block to the next. Therefore function block calls with the same arguments do not necessarily return the same output values!
Should the function block include at least one Retain variable, the whole instance is stored in the Retain area.
2.2.4.2Calling a function block
The input and output variables of a function block can be approached by another organization unit. For this purpose, a function block instance must be generated and the desired variable specified with the help of the following syntax:
<Instance name>.<Variable name>
Input writes only
Input and output reads
•To set the input parameters on call in the IL and ST text languages, assign values to the parameters in brackets after the function block instance name (assignment via := as for the initialization of variables at the point of declaration).
Tip!
SFC allows function block calls in steps only.

2.2.5.1
Program
A program is an organization unit that returns one or several values on execution.
•A program declaration starts with the keyword PROGRAM.
•Programs are known globally throughout the entire project.
•Programs can be called by programs and function blocks. Program calls in a function are not allowed. Programs do not have instances.
•If an organization unit calls a program, thus changing program values, these changes remain active for the next program call, even if the program is called by another organization unit.
Tip!
Only the values in the associated instance of a function block are changed on function block call.
These changes are significant only if the same instance is called.
Program example
Example of a program in IL: |
Examples of calling the program shown on the left: |
|
|
|
|
|
IL |
CAL PRGexample |
|
|
LD PRGexample.par |

|
|
ST |
PRGexample; |
|
|
result:=PRGexample.par; |
|
|
|
|
FBD |
|
|
|
|
Example of a possible call sequence from a main program:
LD 0
ST PRGexample.par (* par is preset with 0 *)
CAL AWLexample (* result in AWLexample = 1 *)
CAL STexample (* result in STexample = 2 *)
CAL FUPexample (* result in FUPexample = 3 *)
• If the variable par of the program PRGexample is initialized with 0 from the main program, and programs are then called successively by means of the above program calls, the result will have the values 1, 2, and 3 in the programs.
• Changing the call sequence will also change the values of the associated result parameters.
Note!
The string length is limited by the applied automation system.

Drive PLC Developer Studio
Introduction
Restrictions occur through limited lengths in the string routines. Only 20 characters can be processed before the string is cut.
The example below illustrates the restriction in online mode.
2.2.6PLC_PRG
PLC_PRG is a special predefined organization unit for a cyclical task. This organization unit is called exactly once per control cycle.
•If Project Insert object is run for the first time after a new project has been created, the dialog box Organization unit is pre-assigned with an organization unit called PLC_PRG of type Program. This pre-assignment should not be changed!
Caution!
Do not delete or rename the organization unit PLC_PRG if you do not use a task configuration. Do not attach PLC_PRG to an already created task as PLC_PRG will then be called several times, leading to logical errors.
PLC_PRG is generally the main program in a single task program.
2.2.7System POUs
System POUs are hardware-dependent POUs (program organization units) with special functions which are provided by the associated PLC (e.g. 9300 Servo PLC, Drive PLC). (Also refer associated PLC manual)

Introduction
2.2.8Resources
Resources are required to configure and organize your project and to trace variable values:
•Global variables to be used throughout the entire project.
•PLC configuration to configure your hardware.
•Task configuration to control your program through tasks.
•Task monitoring to monitor the task runtimes.
•Watch and Receipt Manager to display and pre-assign variable values
•Automation system settings for selection and, if appropriate, for final configuration of the automation system
2.2.9Libraries
The Library Manager can link your project to several libraries whose organization units, data types and global variables can be used in addition to the user-defined ones.
The register card Global Variables contains the variable g_ErrorCheckBounds.
Depending on the selected PLC, some libraries are automatically linked when a new project is created (the library ”standard.lib”, for example).
2.2.10Data types
In addition to the standard data types, users can define some data types of their own. Structures, enumeration types and references can be created.
2.2.11Visualization
The DDS provides visualization to monitor and modify project variables.
The visualization allows offline drawing of geometrical elements that can then change their shape/colour/text output online, depending on certain variable values.

Introduction
2.3Debugging, online functionality
2.3.1Debugging
The DDS debugging functions assist troubleshooting.
•To allow debugging, go to dialog box Options, category Build options and tick check box
Debugging.
Note!
The check box Debugging should be ticked for debugging only.
Breakpoint on, Single step or Single cycle are possible only if Debugging is active.
2.3.2Breakpoint
A breakpoint is a point in the program where processing stops.
•Breakpoints enable the user to look at variable values at a certain program location.
•Breakpoints can be set in all editors. In the text editors, breakpoints are set to line numbers, in FBD and LD to network numbers, in CFC to organization units, and in SFC to steps.
•Breakpoints may be set in the implementation of an initialized function block. No breakpoints may be set in function block instances.
2.3.3Single step
Single step means in:
•IL: Execute program to next CAL, LD or JMP command.
•ST: Execute next instruction.
•FBD, LD: Execute next network.
•SFC: Execute action to next step.
•CFC: Execute next organization unit (box) in the CFC program.
The logical correctness of a program can be checked by step-by-step processing.
2.3.4Single cycle
Selection of Single cycle will stop processing after every cycle.
Caution!
If a breakpoint is set, the use of tasks will lose the real-time response. A 1ms-cycle task will no longer be started every millisecond.
If breakpoints are set, all tasks will be started one after the other after the main program PLC_PRG has been processed. Event-controlled tasks will be started upon a valid start event only.
This, among other aspects, influences the functionality of the generated overall project.

Introduction
2.3.5Changing values online
Variables can be set once-only to a specific value during operation after the command Write values was transmitted to the control. The value of a variable can also be changed online by simply double-clicking it. Boolean variables thus change from TRUE to FALSE and viceversa. For the other variables, the system will display a dialog box Write variable xy to edit the variable value.
2.3.6Monitoring
In online mode, the current values for all variables displayed on screen will be continuously read from the control and displayed. Refer declaration and program editor for this display.
Current variable values may be output in the Watch and Receipt Manager and in a visualization.
The display and monitoring of variables from function block instances requires the associated instance to be opened.
The implementations show the pointer value. The dereferenced value is shown for dereferenced variables.
Monitoring VAR_IN_OUT variables
When monitoring VAR_IN_OUT variables, the de-referenced value is output in the declaration part and the program part.
Monitoring Pointers
Warning!
Monitoring of de-referenced pointer values is not supported by all Lenze target systems.
In online mode, it depends on the target system which de-referenced pointer values (pointer variable^ ) are indicated.
Some Lenze target systems indicate the pointer value itself.
During monitoring the pointer and the de-referenced value are output in the declaration part. In the program part, only the pointer is output.
pointervariable= <pointer value>
Pt= <value>
The value of the pointer is indicated in the implementations, whereas in the case of de-referencing only the de-referenced value is indicated.
Monitoring ARRAY components
The following components are displayed:
• Array components indexed via a constant. anarray[1] = 5
The following components are not displayed:
• Array components with extended index. anarray[i+j] = 5 or anarray[i+1] = 5
2.3.7Simulation
During a simulation on the processor, the generated control program will be processed together with the DDS, offering complete online functionality. The logical correctness of the program can be tested to a limited extent only without control hardware. ( 6-37)
2.3.8Log
The log records user actions, internal processes, status changes and exceptions chronologically in online mode and serves monitoring and error tracing. ( 6-42)

3 Program example “Traffic light”
3.1Introduction
This chapter includes a program tutorial for an easier start with the DDS.
The setup calls for the programming of a mini traffic control system for two traffic lights at an intersection.
•Both traffic lights will alternate their red/green phases.
•To avoid accidents, the traffic lights will also include amber and amber/red between the red and green phases, with the amber/red phase being shorter than the amber phase.
This example illustrates
•how to implement time-controlled programs using IEC 61131-3 language tools.
•how to edit the various standard languages using the DDS.
•how to link the different languages.
•how to simulate a program in the DDS and visualize it on screen.

Tip!
Only the organization unit named PLC_PRG of type “Program” will be processed by the cyclical task. The cyclical task does not need to be explicitly created.
5.Select Sequential function chart (SFC) as the language for this organization unit and confirm with OK.
6.Now create two further objects in the Object Organizer on tab Organization units with the help of Project Object Insert:
–TRAFFICLIGHT type Function block in the language Function block diagram (FBD)
–WAIT type Function block in the language Instruction list (IL)
TRAFFICLIGHT
In the organization unit TRAFFICLIGHT, the individual light phases will be assigned to the traffic lights, i. e., the red light will be on during the red and amber/red phases, the amber light will be on during the amber and amber/red phases, etc.
WAIT
In the organization unit WAIT, a simple timer will be programmed to receive as input the phase duration in milliseconds and to return an output TRUE as soon as the time has expired.
PLC_PRG
The organization unit PLC_PRG links the organization units with each other so that the traffic light emits the correct colour at the correct time and for the specified time. It processes the entire project during the cyclical task.

Drive PLC Developer Studio
Program example
Process
The first interrogation establishes whether Q is already set to TRUE ( TRUE: timer running). [ Line 1]
•If Q is TRUE, we will not change the assignment of DELAY but instead call function block DELAY without input (to check whether the time has already expired). [ Line 10]
•If Q is FALSE, we will set the variable IN in DELAY to FALSE and thus at the same time ET to 0 and Q to FALSE. [ Line 4]
All variables are now set to the desired initial status.
–Now save the time required from variable SETTIME in variable PT [ Line 5/6], and call DELAY with IN:= TRUE. [ Line 7]
–In the function block DELAY , the variable ET will now be counted up until it reaches the value SETTIME ; then Q will be switched to FALSE .
•The negated value of Q will be saved after every WAIT cycle in OK [ Line 14/15]
•As soon as Q becomes FALSE, OK becomes TRUE.
The timer is complete.
3.2.7The main program PLC_PRG
The organization unit PLC_PRG is the main program for calling the two function blocks WAIT and
TRAFFICLIGHT .
29.To edit the organization unit PLC_PRG, activate its editor window by selecting
Object Organizer, tab Organization units and double-clicking PLC_PRG .
3.2.7.1Declaration
To ensure that the function blocks created before can be used in PLC_PRG , it is necessary to declare instances of these function blocks. The traffic light example requires two instances of the function block TRAFFICLIGHT ( LIGHT1, LIGHT2) and one instance of the function block WAIT ( WAIT1).
30.Use the declaration editor to declare as local variable (between the keywords VAR and END_VAR) the variables for the required instances.
3.2.7.2Sequential function chart
The start-up diagram of an organization unit in SFC always consists of an action Init, a subsequent transition Trans0 and a jump back to Init.
