Introduction
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.
In OTX, there are three types of signature:
- The Procedure Signatures
- The Screen Signatures
- The Device Signatures
The procedure signature describes the interface of a sequence (Procedures). The screen signature the interface for input and output within the HMI library (Human Machine Interface). The device signature describes the measurement and control interface of a measurement device or probe.
