MEnv (STRUCT) ¶ TYPE MEnv : STRUCT The environment that is passed to each instance. InOut: Name Type Initial Comment mtree IModuleTree The module tree. Never 0. rmps IRmpService The RMP messge service. 0 if RMP communication is disabled. prsman AC_PERSIST.IPersistenceManager The persistence manager if created, 0 otherwise. exts POINTER TO IEnvironmentExtender Extenders possibly provided by other composer plugins. ATTENTION : Returned externder FBs might be not initialized properly (depending on activated generators, etc.) uiexts UINT 0 Number of possible EnvironmentExtenders visus POINTER TO POINTER TO AC_Visu_Base Pointer to the AC_Visu_FBs for frame changing. ATTENTION : This pointer may be 0 (meaning that i.e. no visus were generated)

Module (FB) ¶ FUNCTION_BLOCK Module EXTENDS BaseInstance IMPLEMENTS IModule Base implementation, should be extended by every function block that implements a module. The standard task methods, the Init method abd the methods OnBeforeOnlineChange and OnAfterOnlineChange call the corresponding methods of all submodules in tree order. The properties have the monitoring attribute ‘call’. For details see IModule .
