Introduction
OTX signatures support the Design By Contract (DBC) approach, 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, you must know nothing about the internal structure.
In OTX there are two types of signature:
The procedure signature describes the interface of a process (Procedures). The screen signature the interface for input and output within the HMI library (Human Machine Interface).
