Reads status of digital input
res = IN n
n = input number
1 – 10 or 1 – 12 (option inputs)
18, 19, 27, 29, 32, 33
res = input status
0 = Low-level or undefined
1 = High-level
The status of a digital input can be read with the IN command. Depending on the
signal level, a 0 or 1 will be given.
The selection of the mode for input 11,12 is done by par. 33-60 IOMODE.
The definition of a high or low level, as well as the input circuit, can be taken from
the "Operating Instructions", as well as from the FC 300 manual.
The inputs 5 and 6 are also used as marker inputs for the master and slave
encoders.

in4 = IN 4 /* store condition input 4 in variable in4 */
IF (IN 2) THEN /* if high level on terminal 2, set output 01 */
OUT 1 1
ELSE
OUT 1 0

Reads analog input
res = INAD n
n = number of the analog input: 53,54
res = analog value
Terminal 53/54:
Terminal 53/54:
The INAD command reads the value of the analog inputs.
I/O
an1 = INAD 53
PRINT "Analog input 53 " ,an1
