Function Libraries The main program, PLC_PRG, is a free-wheeling task equivalent to the organisation module of KUBES programs. PLC_PRG runs exactly once in every control cycle. PLC_PRG is the plug board for other actions such as refreshing the process chart or communicating with the CoDeSys programming system. Event-controlled tasks configured using the Task Configurator (see page 61) are picked from a task list whenever the specified event occurs. They act as interrupt handlers. Their processing starts when the current task has stopped running. Example: a cyclic task to be run at an interval t#10ms will not be processed after every timer interrupt if the main program runs for longer than 10ms. Use function calls to set up event-controlled tasks to run as interrupt service routines. They can interrupt the processing of the current task. To know how to use functions for setting up special tasks, refer to section: 4.4 P690.lib 60 E 700 GB
4.3.3 Task Configuration 4.3.3.1 PLC_PRG Function Libraries Project handling can be controlled by so-called tasks and/or the dedicated PLC_PRG utility program. A task defines as a runtime unit of an IEC program. It is specified by its name, a priority and a type defining the condition that triggers it. A condition can be either timebased (cyclic interval, free-wheeling) or defined by an internal or external event that triggers the task whenever it occurs. Examples would be the rising edge of a global project variable or one of the controller's interrupt events. Every task can be assigned a sequence of programs to be run as the task is being executed. The combination of priority and condition defines the order in time in which the tasks are processed. Every task can have a watchdog (timer-controlled monitor) to it. When running a task in online mode, its actual processing can be viewed by means of a dynamic chart display. There is also the option of directly linking system events (Start, Stop, Reset etc) to running a project module. The CoDeSys runtime system of Ventura Remote PLC has extensive task management features which you should use to optimise the control processes. Run the Task Configurator utility to define the properties of the tasks. Furthermore, function calls can be used to set up special event-controlled tasks/threads as processes of the ARTOS runtime kernel (see page 70 ) PLC_PRG is automatically created as a program-type module every first time you choose 'Project' 'Add Object' to add a module to a new project. PLC_PRG runs exactly once in every control cycle. Generally speaking, PLC_PRG is the main program of a single-task program. If it has no task configuration to it, the project must contain module PLC_PRG. Vice versa, if it does have a task 61
