Standard function blocks
258
Operation
The output (Q1) is 0 if the set input (S) is 1 and the reset input (R) value is 0. The output
will retain the previous output state if the set input (S) and the reset input (R) are 0. The
output is 0 if the set input is 0 and the reset input is 1.

Operation
The output (Q) is set to 1 when the clock input (CLK) changes from 0 to 1. The output is
set back to 0 with the next execution of the block. Otherwise the output is 0.
Note:
The output is 0 after cold restart and after the first execution of the RTRIG block.
Otherwise the output is 1, when the clock input is 1.
