Limit information can be defined centrally in
a reaction matrix (abbr. rema).
Advantages with respect to limits:
Reaction matrices can be used multiple times. A reaction matrix can be linked to several variables that even can be based on different data types.
In contrast to limits reaction matrices do not support a delay. The reaction always is executed immediately, when the limit is violated.
Reaction matrices can handle each value change of a numeric variable as a new limit violation. This is not possible in limits.
More information on limits can be found in the chapter Limits.
