Section: IO
The input and output definition can be done in this section. All defined inputs and outputs are available in the Map I/Os.
SEC IO //optional: yes, modifier: [UPDATE] SEC Input : <input identifier> //optional: yes, modifier [HIDE,UPDATE] Variable := <variable name>; //optional: no, type: InstancePath Name := <name>; //optional: no, type: text Desc := <description>; //optional: no, type: text UpdateInTask := <task name>; //optional: yes, type: TaskRef END_SEC SEC Output : <output identifier> //optional: yes, modifier [HIDE,UPDATE] Variable := <variable name>; //optional: no, type: InstancePath Name := <name>; //optional: no, type: text Desc := <description>; //optional: no, type: text UpdateInTask := <task name>; //optional: yes, type: TaskRef END_SEC END_SEC
For details on the syntax of the definition types see: description in Syntax of the module declaration.
The parameter
Variable
defines the instance path of an input variable or output variable.All components of the path for inputs must be input variables (or local variables in structures). All components of the path for outputs also must be output variables (or local variables in structures). The variable must be primitive data type or enum data type.
A variable can be parameter and input/output at the same time. A variable must not be used by two different I/Os.
The target of an
input
oroutput
section must uniquely identify the input or output. There is no case sensitivity.The parameter
UpdateInTask
determines the task for updating I/Os. If this parameter is missing the task with the flagUPDATE_IOS
will be used. For toplevel modules an error will be created if the task specified inUpdateInTask
is not defined for the module.
