Manual| TESTBIT (v, n) |
| Purpose | To return the logic state of bit #n of the
variable v.
The function returns 1 if the bit is ‘1’, otherwise it returns 0. n is an integer of value between 0 and 15. v may be any integer variable, however, if v is a 32-bit integer TESTBIT will only test the lower significant 16 bits. |
| Examples | IF TESTBIT (Input[2],3) THEN .... ELSE .... ENDIF |
| Comments: | To test whether input #20 is ON (Input channel #2 bit #3 = Input 17 +3 = 20) |
