Logic patterns of fast logic function
The logic patterns of the fast logic function can be selected from the following four patterns.
*1 The logical products of the safety output enable signals (SA\Y0, SA\Y1) and the fast logic output signals (Y0, Y1) are output as the
output signals (Y0, Y1).
*2 The logical products of the safety output enable signal (SA\Y0) and the fast logic output signal (Y0) are output as the output signal (Y0).
• In Pattern 2 to Pattern 4, a reset signal from external and a start signal can be input. In this case, the reset
signal is input to X7 and the start signal is input to X6.
• When using the fast logic function, the safety output signals (SA\Y0, SA\Y1) are used as the safety output
enable signals for the fast logic output. Other safety output signals are ignored even if they are operated
from a program or engineering tool.
• Do not use Pattern 4 in a safety system.
No. Fast logic pattern setting Logical operation circuit of fast logic
1 Pattern 1
Four safety double wiring inputs (without
reset signal)
