Interrupt Input Units are used to execute interrupt programs on the rising or

falling edge of an input signal (See note.). When the specified interrupt input

turns ON (or OFF), execution of the cyclic program in the CPU Unit is inter-

rupted and an I/O interrupt task (task number 100 to 131) is executed. When

execution of the I/O interrupt task has been completed, the cyclic program is

again executed starting from the instruction after which it was interrupted.

Note Only the CS1W-INT01 can detect falling edges. The interrupt control instruc-

tions, however, can be used to switch between upward and downward differ-
