MODULE – Extension module of the REX control system

Block SymbolLicensing group: STANDARD
PIC

Function Description
The REX control system has an open architecture thus its functionality can be extended. Such extension is provided by modules. Each module is identified by its name placed below the block symbol. The individual modules are added to the REX control system configuration by connecting the prev input with the Modules output of the EXEC block or with the next output of a MODULE which is already included in the configuration. There can be only one module connected to the next output of the MODULE block. The next output of the last module in the configuration remains unconnected. This means that the modules create a unidirectional chain which defines the order of initialization and execution of the individual modules.

Each module exists in two versions: one for the development platform (Host) and one for the target platform (Target). The modules are implemented as DLL libraries in Windows and Windows CE operating systems. The naming <modname>_H.dll (for development platform) and <modname>_T.dll (for target platform) is used, where <modname> is the module name.
