Set-Reset Memory Function Block Srmemory - Hitachi Relion 650 Series Technical Manual

Section 11
Logic
Functionality
The AND function is used to form general combinatory expressions with boolean variables. The AND
function block has four inputs and two outputs. One of the outputs is inverted. The output signal is 1 if
all input signals are 1.
Default value on all four inputs is logical 1 which makes it possible for the user to just use the
required number of inputs and leave the rest unconnected. The output OUT has a default value 0
initially, which suppresses one cycle pulse if the function has been put in the wrong execution order.

Function description
Set-reset memory function block
Functionality
The Set-Reset function SRMEMORY is a flip-flop with memory that can set or reset an output from
two inputs respectively. Each SRMEMORY function block has two outputs, where one is inverted.
The memory setting controls if the flip-flop after a power interruption will return to the state it had
before or if it will be reset. In SRMEMORY, the SET input has priority over RESET input.
