Program execution is defined in the organizational modules. The user
can influence the system performance, e.g. start−up, by means of the
available OMs. Events like error detection, interrupt inputs and time−
outs during program execution result in the automatic call of the respec
tive organizational module.
The following table gives a summary of the criteria which define the or
ganizational modules for a given type of program execution. The user
program can be executed in cyclic, interrupt−controlled and time−con
trolled manner.
