PlcShellRegister (FUN) ¶ FUNCTION PlcShellRegister : RTS_IEC_RESULT Register a new Command Handler The command is sent TO the handler as an event OF the EventMgr. So the CommandHandler needs to implement the Interface ICmpEventCallback. Note: For the ease of use, you can also derive your Command Handler from the FB “CommandHandler” in this library. This helps you in the registration and deregistration of the handler. RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Return PlcShellRegister RTS_IEC_RESULT Input pszName REFERENCE TO STRING pszHelp REFERENCE TO STRING pICallback ICmpEventCallback

PlcShellSetEof (FUN) ¶ FUNCTION PlcShellSetEof : RTS_IEC_RESULT Set EOF This function should be called when the Command Handler is finished with it’s output. RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Return PlcShellSetEof RTS_IEC_RESULT

PlcShellSkip (FUN) ¶ FUNCTION PlcShellSkip : RTS_IEC_RESULT Skip a number of blocks in the output. If a Command Handler sends a huge amount of output, it might be necessary, that this output is splitted into several blocks by the communication layer. When this happens, the communication layer will discard everything, but the current block from the output and recall the Command Handler several times. To avoid this, an intelligent Command Handler can generate only the currently necessary block of output. For this, it needs to “skip” all blocks, which are already sent, by calling this function. Then it should write only that much data, that they fit into one block and call PlcShellSetEof() when it is finished. RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Return PlcShellSkip RTS_IEC_RESULT Input iBlockID DINT

PlcShellUnregister (FUN) ¶ FUNCTION PlcShellUnregister : RTS_IEC_RESULT Unregister a new Command Handler Unregister the command handler, which is passed to this function. Most likely this function will be used in FB_exit, because every Command Handler in IEC has to unregister when the application is deleted. RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Return PlcShellUnregister RTS_IEC_RESULT Input pICallback ICmpEventCallback
