*1: 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.
*2: This is available for multiple CPU system configuration.
*3: 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 Section 6.22.
*4: I50 has the highest priority (priority 22), and I255 has the lowest priority (priority 227).
*5: When an interrupt occurs, even if no interrupt pointer exists on the program, CANíT EXECUTE(I) (error code: 4220) does not occur.
