Other-wise the keyboard buffer is cleared.0: Buffer is not clearedDefault: 10sCountCharAu-toEnterINPUT INT Number of characters, which are automatically outputas keyboard buffer.0: deactivatedDefault: 0Output OUTPUT STRING[16] Contents of the keyboard buffer as max. 16 bytestring.Valid OUTPUT BOOL The static output indicates that the string at Output isvalid. The signal is pending for one cycle.Error OUTPUT BOOL Error is activated for the time TimeError when a keyis pressed, but the keyboard buffer is full.TimeDebounce CONSTANT TIME Time for debounce of the inputs.Default: 100msTimeError CONSTANT TIME Time for the duration of the error signal.Default: 500ms7.3.5 FB 50 - KEYPAD2 - KeyboardThis block is used to connect an external keypad (0...9,*,#) without an own power supply.The block provides output column signals. Depending on the pressed key, the keyboardprovides the according row signals. The block evaluates the signals internally by meansof a bit pattern table and transfers the determined ASCII code into the keyboard buffer. Ifnecessary, or automatically the keyboard buffer is output as max. 16byte character string.n Via Row 1...4 the rows 1...4 of the keyboard matrix are connected.n Via Column 1...3 the columns 1...3 of the keyboard matrix are connected.n Via TimeDelay you can specify a waiting time after setting the column outputs up toreading the corresponding row inputs. This time must be greater than the delay timeof the used module.n Via ClearCode you can specify a key code to clear the keyboard buffer.DescriptionVIPA SPEED7 Building ControlAccess Control > FB 50 - KEYPAD2 - KeyboardHB00 | OPL_SP7 | Operation list | en | 18-30 111
