BitOfDWord 126 pt 140 pt 154 pt 168 pt 182 pt 196 pt 210 pt With this function, it is possible to `filter' (extract) a bit out of the Double Word that is entered as an input parameter (`InDWord'). The result of the function is `bool'. Input BitNo defines which bit of the input word shall be extracted (BitNo=0 -> Bit0; BitNo=1 -> Bit1). The input parameter `BitNo' has to be within limits 0 . 31. Values outside this limits generate an error code. 224 pt 238 pt Block type: Function BitOfDWord: BOOL 252 pt Input InDWord :DWORD input data BitNo :INT bit number 0.31 which is to be extracted :BOOL output bit 266 pt 280 pt Output 294 pt 308 pt 322 pt 336 pt 350 pt 364 pt 378 pt 392 pt 406 pt 420 pt 434 pt 448 pt 462 pt 476 pt 490 pt Diagnostics Static internal variables for diagnostics Error_Code :INT When input-parameter (`BitNo') is outside the foreseen limits [ 0 . 31 ], following error-code is returned: BitNo < 0 Error_Code = 1 BitNo > 31 Error_Code = 2 Examples Suppose : InDWord := 2#1000_0001_0000_0100_0101_0110_0100_0001 · · BitOfDWord (InDWord, 6) = `1' BitOfDWord (InDWord, 1) = `0' 504 pt 518 pt 532 pt 546 pt 6. INT_to_BCD 560 pt 574 pt 588 pt This function converts a numerous INT data format to BCD coded data.

Latch 126 pt 140 pt 154 pt 168 pt 182 pt 196 pt This function block passes through the signal from the input DataI to the output DataO, as long as input L_En =TRUE. Once the input L_En detects a falling edge the output stores the data value applied to the input at this moment. The output keeps this data value, it does not follow anymore the changes of the input signal. The "latched" output can be reset by the input Res at any time, i. e. the output is set to the actual value of DataI and the output follows then the input value again. 210 pt 224 pt 238 pt Input L_En: TRUE: DataO = DataI FALSE (falling edge): hold DataO -> DataO = DataI (at f-edge time). 252 pt 266 pt 280 pt Block type: Function Block Latch 294 pt Input DataI :BOOL input data L_En :BOOL latch enable Res :BOOL resets the output DataO :BOOL output data 308 pt 322 pt 336 pt 350 pt Output 364 pt 378 pt 392 pt 406 pt 8.

These inputs can be enabled or disabled by the inputs En1.En3. If an enable input (En1.En3) is FALSE the assigned input (In1.In3) is ignored. This allows to select which of the input signals (In1.In3) are to be used for the interpretation of the biggest value out of 1 or 2 or 3 which is to be returned by the function. By this it is also possible to force only one input to be returned by the function which gives the possibility to check (by return value) the individual value of each input signal. 574 pt 588 pt If all Enable inputs are FALSE the function returns zero. 602 pt 616 pt Block type: Function MaxOf_SEn: DWORD Input In1 :DWORD Input variable 1 658 pt In2 :DWORD Input variable 2 672 pt In3 :DWORD Input variable 3 686 pt EN1 :BOOL Enable signal for Input variable 1 (IN1) EN2 :BOOL Enable signal for Input variable 2 (IN2) EN3 :BOOL Enable signal for Input variable 3 (IN3) :DWORD Returns maximum value of the enabled inputs 630 pt 644 pt 700 pt 714 pt 728 pt 742 pt Output 756 pt 770 pt 784 pt 798 pt 812 pt 826 pt Pilz GmbH & Co.

MinMax 238 pt 252 pt 266 pt 280 pt This function block stores the minimal and maximum value of an input signal until they are deleted by a reset signal.

The output Out is set to FALSE when the periodic time, specified on input Ptime has elapsed, even if the input In is still TRUE.

If not enabled, both feedback input can be either FALSE or TRUE fix value If the feedback loops are used, then an alarm message is shown after the transition of an output without transition of feedback loop. The check is done with a delay Delay time for feedback loop check, is an additional input FblD_T Alarm messages are generated if the feedback loops don't work properly, but don't influence the motor behaviour. The programmer who uses this block must be able to decide if this is a dangerous alarm or not and act in the proper way.
