Built-in Inputs Section 6-1
Procedure
Restrictions on General-purpose Inputs
• General-purpose inputs 0 to 3 cannot be used when built-in inputs IN0 to
IN3 are being used as interrupt inputs or quick-response inputs.
• General-purpose inputs 8 and 9 cannot be used when high-speed
counter input 0 is being used. Furthermore, general-purpose input 3 can-
not be used if the high-speed counter 0 reset method is set to Phase-Z
signal + Software reset.
General-purpose inputs 6 and 7 cannot be used when high-speed
counter input 1 is being used. General-purpose input 2 cannot be used if
the high-speed counter 1 reset method is set to Phase-Z signal + Soft-
ware reset.
• General-purpose inputs 0 and 1 cannot be used when the origin search
function is enabled for pulse output 0 (enabled in the PLC Setup). Also,
general-purpose input 4 cannot be used when operating mode 2 has
been specified, i.e., the Positioning Completed Signal is being used.
General-purpose inputs 2 and 3 cannot be used when the origin search
function is enabled for pulse output 1 (enabled in the PLC Setup). Also,
general-purpose input 5 cannot be used when operating mode 2 has
been specified, i.e., the Positioning Completed Signal is being used.

Wire inputs.
PLC Setup settings
Ladder program
• IN0 to IN9 (CIO 2960 bits 00 to 09)
• Connect to the selected terminals between IN0 and IN9.
• When IN0 to IN3 are used as general-purpose inputs, make
the necessary "input operation settings" for IN0 to IN3 in
Programming Console address 60.
IN0: Set the rightmost digit (bits 00 to 03) to 0.
IN1: Set the second digit (bits 04 to 07) to 0.
IN2: Set the third digit (bits 08 to 11) to 0.
IN3: Set the leftmost digit (bits 12 to 15) to 0.
The default setting for address 60 is 0000 (inputs IN0 to IN3
used as general-purpose inputs.)
• When setting the input time constant (ON response time),
make the necessary "input time constant setting" in
Programming Console address 61. The input time constant
setting applies to general-purpose inputs IN 0 to IN9 only.
00 hex: Default (8 ms); 10 hex: No filter; 11 hex: 0.5 ms; 12
hex: 1 ms; 13 hex: 2 ms; 14 hex: 4 ms; 15 hex: 8 ms; 16 hex:
16 ms; 17 hex: 32 ms
• Use the general-purpose inputs in instructions such
as LD.
• To use the immediate-refreshing variation, add the
"!" prefix to the instruction. For example: !LD.
Note: Immediate refreshing cannot be performed by the
IORF(097) instruction.
