■For an interrupt by a special device (SB, SW)
The specified interrupt program can be executed in the condition of the control information (SB, SW) for data link.
Ex.
The following shows an example of executing an interrupt program with the interrupt pointer I51 when 'Data link error status of
own station' (SB0049) of the control station (station No.15) is turned on (error).
RJ71LP21-25
CPU module Station No.3
SB0049
1.
Set the interrupt setting parameters for the control station (station No.15) of the RJ71LP21-25 as shown below.
• If the program is fast, the execution time of the interrupt program may be affected, thereby leading to the
effect of the interrupt program not being fully exerted and resulting in the scan time being extended.
• When multiple interrupts occur simultaneously, an operation delay may occur.
• This function cannot be used during offline or online test operation.
