SysDirAsync Library Documentation ¶ Company System Title SysDirAsync Version 3.5.19.0 Categories System|SysLibs Author 3S - Smart Software Solutions GmbH Placeholder SysDirAsnc Description 1 ¶ All asynchronous system libraries are only asynchronous wrappers around their underlaying System-Library. So this library is only an asynchronous wrapper around the SysDir.library. The asynchronous functions are named as the correspnding function in the base library, but only with the ending <SysFunction>Async. Every asynchronous system function is included in one function block, with the ending <SysLib>AsyncFB. This FB must be instantiated to use all asynchonous methods. Each asynchronous method has 3 parameters: t<SysFunction>: Pointer to the parameter structure (see below) pudState: Pointer on current status of the asynchonous action: ASYNCSTATE_INVALID : UDINT := 16#FFFFFFFF ; ASYNCSTATE_PENDING : UDINT := 0 ; ASYNCSTATE_ACTIVE : UDINT := 1 ; ASYNCSTATE_READY : UDINT := 2 ; ASYNCSTATE_ERROR : UDINT := 3 ; ASYNCSTATE_TIMEOUT : UDINT := 4 ; The status at starting the asynchronous job always is ASYNCSTATE_INVALID. pResult: Pointer to runtime system error code (see CmpErrors.library) Each asynchonous method gets the same parameter as the base system library, but they are collected to one parameter structure. The name of this parameter structure has always the prefix “t”: t<SysFunction> For a description of the particular function parameters please see the chapters on the corresponding functions in the documentation on the System-Base library (<SysLib>.library). When calling the asynchronous method, the asynchronous job gets started. The job will be finished as soon as the status has got one of the following three values: ASYNCSTATE_READY: Job successfully finished ASYNCSTATE_ERROR: Job terminated with error ASYNCSTATE_TIMEOUT: Job timeout reached before job could be finished successfully The last parameter in the parameter structure contains always the result of the base system function indicating whether the asynchronous job could be finished successfully of not. The result value of each asynchronous method is the handle of the asynchronous job. By use of this handle and the functions of the library CmpAsyncMgr.library further information on the asynchronous job can be retrieved. USAGE of the FB: ¶ Before first use of the function block, you have to call AsyncSetJobParams() to initialize the asynchronous manager. After this, you can use any of the asynchronous methods!
