(3) Each multiple CPU high speed transmission cycle (High-speed Universal
model QCPU and Universal model Process CPU only)
After the I45 interrupt program is executed, data are collected at the specified interval.
Ex.
When the interval is set to 3

Sampling
Data can be collected only when the following conditions are all met.
• A multiple CPU high-speed main base unit (Q3DB) is used.
• The system contains two or more CPU modules (multiple CPU system), and the use of the multiple CPU high-
speed transmission function is enabled.
• The program includes an interrupt pointer (I45).
• The EI instruction is being executed, and the interrupt pointer (I45) is not masked.
(4) Condition specification
Data are collected when the state of the specified device or step meets the specified condition. Furthermore, if
both of (a) and (b) are selected, an AND condition can be created.
(a) Device specification
Data are collected when the specified device condition is met in the END processing of each scan.
<Data are continuously collected while the condition is satisfied.>
While the condition of the specified device is met, device data are collected in the END processing of each
scan. Set the following.
• When the word device value meets the specified value: When the current value of the specified device is
the specified value
