Basic Function <strong>Instruction</strong>FUN 6 D PBSHFSymbolBIT SHIFT(Shifts the data of the 16-bit or 32-bit register to left or to right by one bit)FUN 6 D PBSHFOperandD: The register number for shiftingOperandRangeWY WM WS TMR CTR HR OR SR ROR DRWY0∣WY240WM0∣WM1896WS0∣WS984T0∣T255C0∣C255R0∣R3839R3904∣R3967R3968∣R4167R5000∣R8071D0∣D4095D ○ ○ ○ ○ ○ ○ ○ ○* ○* ○Description● When the status of clear control "CLR" is at 1, then the data of register D and FO0 will all be cleared to 0.Other input signals are all in effect.●When the status of clear control is "CLR" at 0, then the shift operation is permissible. When the shift control"EN" = 1 or "EN↑" ( P instruction) from 0 to 1, the data of the register will be shifted to right (L/R=0) or toleft (L/R=1) by one bit. The shifted-out bit (MSB when shift to left and LSB when shift to right) for bothcases will be sent to FO0. The vacated bit space (LSB when shift to left and MSB when shift to right) due toshift operation will be filled in by the input status of fill-in bit "INB".ExampleShifts the 16-bit register dataLadder diagram Key Operations Mnemonic CodesORG ORG X 1X1X2ENINB6P.BSHFD : R 3OTBY0LDLDLDLD X 2LD X 3LD X 4X3X4L/RCLRFUNFUN 6PD: R 3FO 0OUTOUT Y 0B15 B0X3=1← ← ← ← ← ← ← ← ← ← ← ← ← ← ← ← ← ←(Left shift) Y0 Shifts the 16-bit data to left by one bit X2B15 B0X3=0→ → → → → → → → → → → → → → → → → →(Right shift) X2 Shifts the 16-bit data to right by one bit Y06-20

The nature of the instruction is a Pinstruction. Therefore, when the clock “CK↑” is 0→1 (rising edge), the CV will increased by 1 (if U/D=1) ordecreased by 1 (if U/D=0).When CV=PV, FO0(“Count-Up) will change to 1”. If there are more clocks input, the counter will continuecounting which cause CV≠PV. Then, FO0 will immediately change to 0. This means the “Count-Up” signalwill only be equal to 1 if CV=PV, or else it will be equal to 0 (Care should be taken to this difference fromthe “Count-Up” signal of the general counter).The upper limit of up count value is 32767 (16-bit) or 2147483647 (32-bit). After the upper limit is reached,if another up count clock is received, the counting value will become –32768 or -2147483648 (the lowerlimit of down count).The lower limit of down count value is -32767 (16-bit) or -2147483647 (32-bit). After the lower limit isreached, if another down count clock is received, the counting value will become 32768 or 2147483648(the upper limit of up count).If U/D is fixed as 1, the instruction will become a single-phase up count counter. If U/D is fixed as 0, theinstruction will become a single-phase down count counter.ExampleThe diagram below is an application example of UDCTR instruction being applied to an encoder.2-phase encoderBlackRed (POWER + 24VDC)Green (B phase)White (A phase)SWC X16 X17 X18PLC6-21
