|Short Description||Interface description to another module|
|Specified by||ISO 13209-2|
OTX signatures support the design by contract (DBC) concept, see Signature Concept. A signature is therefore a description of an interface to another module so that the user, who wants to use this module, needs to know nothing about the internal structure.
OTX allows different types of signatures:
- The Procedure Signatures describe the interface of a sequence (Procedures).
- The Screen Signatures describe the interface for input and output within the HMI library (Human Machine Interface).
- The Device Signatures describe the measurement and control interface of a measurement device or probe.
