Application Function

Interrupt program activation

Check the interrupt condition when receiving data from another station using the interrupt settings parameters of the own
station. When the interrupt condition is established, an interrupt request is sent from the RJ71LP21-25 to the CPU module,
and the interrupt program of the CPU module on the own station is activated.
Setting method
Set the interrupt request to the CPU module in "Interrupt Settings" under "Application Settings". ( Page 66 Interrupt
Settings)

Multiplex transmission function

This function is used to perform high speed communication using duplex transmission path (forward loop and reverse loop).
The RJ71LP21-25 cannot operate as a control station with multiplex transmission.
However, in the environment where the QJ71LP21-25 with multiplex transmission operates as a control
station, the RJ71LP21-25 is allowed to participate in the network as a sub-control station or normal station.
For details on multiplex transmission, refer to the following.
