A general introduction to the subject of VISONIK reactions can be found under
"Reactions in General" in section R of this manual.
The step reaction register function (SRR) is one of six reaction types provided by the
VISONIK DCS. The reaction types are named after the reason (cause) that activates the
reaction in each case.
Each reaction entry consists of the following three parts:
–
"reason" that activates the reaction
–
Blocking flag that can disable a reaction
–
Reaction to be executed
Dependent on the status change in a flag, the step reaction register function can
execute a sequence of mutually linked reactions.
