Variable names and file (program) names MUST differ ! Keywords must not be used as variable names ! Sample: A variable named LT (e.g. for the function „lamp test“) will lead to an error message because LT is the reserved keyword for a comparator !

Use a capital letter as the first letter and use small letter for the rest. Separate variable names consisting of several word by underscores between the words and start each word with a capital letter. When working with brackets please use indentions for each level. e.g. use one TAB for each new bracket level. Always put jump labels in a separate line and highlight them by e.g. framing them with comments All below mentioned hints serve the purpose of making your programs easy to read and give them a well-defined structure: Hints for the creation of programs IEC-Basics and basic logic circuits

For the execution the following rules are valid:.The task, for which the condition is fulfilled, will be executed, i.e. if the time period has elapsed or on the rising edge of the associated global triggering event. ·If several task have valid conditions at the same moment the task with the highest priority will be executed first. ·If several tasks have valid conditions and the same priority the task with the longest waiting time will be executed.
