Command, function and parameter description Section 6-3
6-3-99 IN
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
group of inputs. The two arguments must be less than 24 apart.
• IN(input_number) with the value for input_number less than 32 will return
the value of the particular channel.
• IN (without arguments) will return the binary sum of the first 24 inputs (as
IN(0,23)).
Refer to 3-3-2 Digital I/O for a description of the various types of output and
inputs.
Arguments:
input_number
.
The number of the input for which to return a value. Value: An integer
between 0 and 31.
final_ input_number
.
The number of the last input for which to return a value. Value: An integer
between 0 and 31.

Examples: Example 1
The following lines can be used to move to the position set on a thumbwheel
multiplied by a factor. The thumbwheel 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 2
In this example a single input is tested:
test:
WAIT UNTIL IN(4)=ON ‘Conveyor is in position when ON
GOSUB place
6-3-100 INDEVICE
Type: I/O Parameter
Description: The INDEVICE parameter defines the default input device. This device will be
selected for the input commands when the #n option is omitted. The INDE-
VICE parameter is task specific. The following values are supported.
0 RS-232C programming port 0 (default)
1 RS-232C serial port 1
2 RS-422A/485 serial port 2
5 Motion Perfect port 0 user channel 5
6 Motion Perfect port 0 user channel 6
7 Motion Perfect port 0 user channel 7
