Type I/O function
Syntax IN(input_number [ ,final_input_number ])
IN
Description The IN function returns the value of digital inputs.
• IN(input_number, final_input_number) will return the binary sum
of the
final_input_number]. The two arguments must be less than 24
apart.
• IN(input_number) will return the value of the particular input speci-
fied by the parameter input_number.
Arguments • input_number
The number of the input for which to return a value. The range for
this parameter is 0..255.
• final_ input_number
The number of the last input for which to return a value. The range
for this parameter is 0..255.
Example The following lines can be used to move to the position set on a thumb
wheel multiplied by a factor. The thumb wheel is connected to inputs 4,
5, 6 and 7, and gives output in BCD.
moveloop:
MOVEABS(IN(4,7)*1.5467)
WAIT IDLE
GOTO moveloop
The MOVEABS command is constructed as follows:
Step 1: IN(4,7) will get a number between 0 and 15.
Step 2: The number is multiplied by 1.5467 to get required distance.
Step 3: An absolute move is made to this position.
Example In this example a single input is tested:
test:
WAIT UNTIL IN(4)=ON ' Conveyor is in position when ON
