Input Unit Specifications Section 2-2
IR 00000 to IR 00015 are always allocated to the CPU Unit’s 16 built-in input
points.
• Inputs IN0 to IN 3 (corresponding to IR 00000 to IR 00003) can be set in
the PC Setup to be used as input interrupts.
• Inputs IN4 to IN7 (corresponding to IR 00004 to 00007) can be used as
high-speed counter 0.
Note If IN0 through IN3 are set for use as input interrupts in the PC Setup, the ON
and OFF delays for input interrupts are fixed at 0.1 ms max. and 0.5 ms max.,
respectively. If IN4 through IN6 are set for use as high-speed counter inter-
rupts, the delays for high-speed counters are as shown in the following table.
