“Dir” refers to direction control function. OFF indicates counting up; ON indicates counting
down.

When X1, X3, X4 and X5 is applied for reset function and associated external interrupts are
disabled, users can define the reset function as Rising/Falling-edge triggered by special M
relays

9.
When X1, X3, X4 and X5 is applied for reset function and external interrupts are applied, the
interrupt instructions have the priority in using the input points. In addition, the ELC will move
the current data in the counters to the associated data registers below then reset the counters.

When C243 is counting and external interrupt is triggered from X1(I101), counted value in C243 will
be move to D0 immediately then C243 is reset. After this interrupt I101 executes.
