5 SEQUENCE INSTRUCTIONS
5.4 Shift Instructions
Processing details
■
Bit device
• These instructions shift the on/off state of the device area just before the one specified by (d) to the device area specified
by (d). After the data is shifted, the data of the shift source device area is turned off.
Ex.
When the SFTP instruction that specifies M11 is executed, it shifts the on/off state of M10 to M11, and turns off M10.
• Turn on the shift target start device by using the SET instruction.
• When the SFT(P) instruction is used consecutively, program devices in descending order of the device numbers.
■
Bit-specified word device
• These instructions shift the 1/0 state of the bit just before the one specified by (d) to the bit specified by (d). After the data is
shifted, the data of the shift source bit is set to 0.
Ex.
The SFT(P) instruction that specifies D0.5 (b5 in D0) is executed, it shifts the 1/0 state of b4 in D0 to b5, and sets b4 to 0.
