F133_BTT

Checks the state [1 (ON) or 0 (OFF)] of bit position n in the 16-bit data specified by d if the trigger EN is in the ON-state.

Parameters

Input

d (WORD, INT, UINT)

16-bit area

n (INT)

Specifies the bit position to be checked in decimal data. Range: 0–15

Remarks

Instead of using this F instruction, we recommend using the corresponding FP7 instruction: FP_TEST_BIT

The specified bit is checked by the system variable sys_bIsEqual.

• When specified bit is 0 (OFF), sys_bIsEqual (=flag) turns ON.

• When specified bit is 1 (ON), sys_bIsEqual (=flag) turns OFF.
