Parameter
Data Type
Memory Area
Description
<address>
BOOL
I, Q, M, D, L
The address specifies which bit will be set or reset.
S
BOOL
I, Q, M, D, L, T, C
Reset instruction enabled
R
BOOL
I, Q, M, D, L, T, C
Set instruction enabled
Q
BOOL
I, Q, M, D, L
Signal state of <address>





Description



The Reset_Set Flip Flop instruction executes instructions such as Set (S) or Reset (R) only when the RLO is 1. An RLO of 0 does not affect these instructions, the address specified in the instruction is not changed.



Reset_Set Flip Flop is reset when the signal state at input R is 1 and the signal state at input S is 0. If input R is 0 and input S is 1, the flip flop is set. If the RLO at both inputs is 1, the flip flop is set.



The Reset_Set Flip Flop instruction is affected by the Master Control Relay (MCR). For more detailed information about how the MCR functions, refer to MCR on/off.
