Operating in simulator mode, CannyLab performs actions with data of the diagram, equivalent to those to be executed by a controller computing kernel when running diagram on it, that allows simulate the operation of the controller on a PC.
The user can run the simulation of execution the functional diagram for debugging and testing at any stage of its creation. In simulation mode it is possible cycling and stepping through diagram, setting the conditions to pause the execution, forced setting inputs and outputs values of function blocks, control of intermediate values.
| Note: | In the current version of CannyLab simulator there is no support of controller hardware resources, so the reading results from addresses and write to the address in the simulator may differ from the results obtained in diagram execution by the controller. |
Contents
Enabling simulation mode
Enabling and disabling the simulation mode is done by selecting the appropriate item in the «Simulator» of main menu, or by pressing 
of toolbar.
In simulation mode, the appearance of the main window and diagram changes - removed not available in this mode dialog elements, debugging information is added on the diagram.
When the simulation is activated, will be performed a consistency diagram check, count memory (RAM) and program memory (ROM) which require the controller to run it. If problems are found the user will be warned about them.
Also, when the simulation mode is activated will be automatically detected and displayed functional blocks order of execution. All intermediate values of inputs and outputs of functional blocks, blocks internal memory and the value of all the networks will be reset to 0, a pointer to the next block in the execution queue will be set to the first block of the diagram, set simulation clocking to real time.
In simulation mode, the user can freely move around the diagram and change scale, but editing diagram elements in this CannyLab mode is restricted.
Continuous diagram execution
Running a continuous diagram execution by simulator is performed by selecting «Simulator» → «Start» of main menu or click the button 
toolbar, which in this case takes the following form 
.
| Note: | The items "Start" and "Pause" of menu "Simulator" and buttons and of toolbar are combined and are activated depending on the current state of the simulator.
|
When binding simulator clock to real time 
, which is enabled by default in the simulation mode, the simulator clock 
start the countdown looping diagram execution with a speed of PC system clock. If disable this binding, simulator internal clock will go as fast as possible, determined by the performance of the PC.
The scale of diagram time 
sets the increment that will be added to simulator clock after each pass of the diagram. This parameter can be seen as the time it takes the controller to once full execute of users diagram.
| Note: | To debug a large user diagrams implementing critical to runtime algorithms for PLC CANNY 7 time scale is recommended to set at the rate of 1 ms for every 30 function blocks. |
When changing the values of inputs and outputs of the functional blocks during the execution of the diagram, a new values are displayed on diagram immediately beside them. For clarity, the network connected to the outputs of blocks having a value other than zero, will be highlighted.
Pause and reset
Execution of diagram by simulator, can pause, selecting «Simulator» → «Pause» of main menu or click the button 
of toolbar, which in this case takes the following form 
.
A functional block in which diagram execution has been suspended, will be highlighted in yellow. Networks, with the values has changed in the last step will also be highlighted, simulator clock will be stopped.
| Note: | The items "Start" and "Pause" of menu "Simulator" and buttons and of toolbar are combined and are activated depending on the current state of the simulator.
|
If enable auto-tracking option for the current diagram block selecting «Simulator» → «Show block» of main menu or click the button 
of toolbar, display diagram in the workspace is shifted so that the working area contain a functional block on which execution was suspended.
Continuing diagram execution at a point where it was interrupted, performed by selecting «Simulator» → «Start» of main menu or click the button of toolbar.
Full stop diagram execution process and reset simulator to the initial state performed by selecting «Simulator» → «Reset» of main menu or click the button 
of toolbar.
Conditional pausing
The simulator provides the ability to automatically pause the execution of the diagram on the following conditions:
- when any value on the diagram has changed;
- when the value of a particular network on the diagram has changed;
- after execution of the next functional block on the diagram (step mode);
- before the execution of a specific function block on the diagram;
- on completion of a full cycle of the diagram;
Enabling and disabling automatic suspension of execution for any data changes performed by selecting «Simulator» → «Watch Changes» of main menu or click the button 
of toolbar.
Execution of the next function block, followed by suspension of diagram execution performed by selecting «Simulator» → «Next» of main menu or click the button 
of toolbar.
Performing one full diagram cycle with the suspension of execution of the current function block performed by selecting «Simulator» → «Loop» of main menu or click the button 
of toolbar.
Installing and removing a breakpoint on a particular functional block is performed by selecting the appropriate context menu item, available at the click of the right mouse button on the block. Background of the function block header declared breakpoint in simulator mode will be highlighted in red.
In the presence on the function block declared as breakpoint on the diagram, execution of the diagram will be suspended before each execution of each such block.
Installing and removing a breakpoint on a specific network is performed by selecting the appropriate context menu item, available at the click of the right mouse button on any network segment. The color of all segments of the network declared a breakpoint in simulator mode will be changed to red.
In the presence of networks on the diagram declared breakpoints, diagram execution is suspended each time the value of each such network has changed.
| Note: | Set or remove a breakpoint in the network or function block can be done also by double-clicking the left mouse button on these diagram elements. |
Принудительное изменение значений
Для имитации внешних воздействий на диаграмму во время симуляции, в симуляторе предусмотрена возможность ручного принудительного изменения текущего значения сетей.
Принудительное изменение значения сети производится выбором пункта контекстного меню «Установить значение» доступного по нажатию правой кнопки мыши на любом сегменте сети.
В открывшемся после выбора этого пункта диалоговом окне вводится устанавливаемое принудительно значение.
Значение, принудительно установленное для сети, отображается в виде надписи на черном фоне.
Установленное принудительно значение сети будет использоваться функциональными блоками, соединенными с данной сетью вместо её реального значения до тех пор, пока не будет освобождено вручную.
Возврат сети к получению значения определяемому работой диаграммы производится выбором пункта контекстного меню «Освободить значение» доступного по нажатию правой кнопки мыши на любом сегменте сети с принудительно установленным значением.
Быстро принудительно установить значение какой-либо сети равное единице, или быстро освободить значение сети можно также при помощи двойного нажатия левой клавиши мыши на данной сети, удерживая нажатой клавишу «Ctrl».
Изменение системы счисления отображаемых значений
По умолчанию, все значения отображаются в симуляторе в десятичном виде. Однако, систему счисления отображаемых значений можно в любой момент изменить, например на шестнадцатеричную, выбрав соответствующий пункт подменю «Симулятор» → «Формат значений» главного меню программы.
