Interrupt by the

internal timer

The time-limit value of the internal timer is set by default. In the PLC system tab of the PLC parameter dialog box, the

value can be changed within the range of 0.5ms to 1000ms in increments of 0.5ms.

This is available for multiple CPU system configuration.

To use the intelligent function module interrupt, the intelligent function module setting (interrupt pointer setting) is

required in the PLC system tab of the PLC parameter dialog box. (For interrupt from an intelligent function module, refer

to Page 229, Section 3.22.)

I50 has the highest priority (priority 6), and I255 has the lowest priority (priority 211).

When an interrupt occurs, even if no interrupt pointer exists on the program, CAN'T EXECUTE(I) (error code: 4220)

does not occur.

To use I49, do not execute any other interrupt programs (I0 to I48, I50 to I255) nor fixed scan execution type programs.

If executed, the interrupt program (I49) will not be executed at preset intervals.
