Type Mathematical operation
Syntax expression1 AND expression2
Description The AND operator performs the logical AND function on the corre-
sponding bits of the integer parts of two valid BASIC expressions.
The logical
AND function between two bits is defined as follows:
0 AND 0 = 0
0 AND 1 = 0
1 AND 0 = 0
1 AND 1 = 1
Arguments • expression1
Any valid BASIC expression.
• expression2
Any valid BASIC expression.
Example VR(0) = 10 AND (2.1*9)
The parentheses are evaluated first, but only the integer part of the
result, 18, is used for the
AND operation. Therefore, this expression is
equivalent to the following:
VR(0) = 10 AND 18
The AND is a bit operator and so the binary action is as follows:
01010 AND 10010 = 00010
Therefore, VR(0) will contain the value 2.
Example IF MPOS AXIS(0) > 0 AND MPOS AXIS(1) > 0 THEN GOTO cycle1
If measured positions MPOS of both axis 1 and axis 2 are greater than
zero, program execution continues at label cycle1 . Otherwise, program
execution continues with the next statement.

Type I/O command
Syntax AOUT(analogue_chan)
Description The AOUT reads a value from the AOUT array. The CJ1W-MCH72
does not provide any analogue output. The contents of the AOUT array
may be mapped to PLC memory to transfer values to e.g. PLC ana-
logue output units.
Arguments • analogue_chan .
Analogue output channel number 0.31
Example No example.
