Using Interrupts 323
Each EII can be configured to monitor any one of the first eight inputs
(I1:0.0/0 to I1:0.0/7). Each EII can be configured to detect rising edge or
falling edge input signals. When the configured input signal is detected at
the input terminal, the controller immediately scans the configured
subroutine.
