(c) Starting the interrupt program of station No.15 when data sent from station No.3 with
the SEND instruction are received in the channel specified in the RECVS instruction
(channel 5)
• Interrupt setting
• Intelligent function module interrupt pointer setting
● When "Level Detect" is set for "Detection Method" and the interrupt condition is always met, do not use interrupt setting
and check the interrupt condition in the program. If the sequence scan time is much longer than the link scan time, since
interrupt processing is activated in each link scan, sequence scan time may greatly increase, resulting in a watchdog
timer error of a CPU module.
● When multiple interrupt requests occur at the same time, the operation may be delayed.
● The interrupt function cannot be used during the offline or online test.
● Do not use the interrupt program start by rise or fall of the specified device (with PLS or PLF instruction, etc.
respectively), because the device status change could not be read out.
