1.5 Functions
overview
ProSafe-COM enables communication between the ProSafe safety system and other systems (CENTUM,
COM SET, other DCS systems etc.). ProSafe-COM functions autonomously and requires no operator
actions. The basic function of ProSafe-COM is to enable communication between the ProSafe safety
system and various other systems. The following picture gives a high-level impression of the ProSafe-
COM functions.

Communication with ProSafe safety system
Status of process variables and event messages can be retrieved by ProSafe-COM from the ProSafe
safety system. In case of an override procedure, statuses can also be written into the ProSafe safety
system.
SER: Sequence of Events Recording
ProSafe-COM keeps track of changes in the ProSafe safety system and maintains a Sequence of Events
Recording. All configured signal changes are stored, sorted on time.
Using tags
Tags make communication possible between several systems (for example CENTUM and ProSafe safety
system). By means of tags it is easy to design the overall communication between available systems. It is
also possible to define which signals are communicated to what system. Not all systems need the same
data. So selections can be made by means of groups of tags.
Logical operations
ProSafe-COM has the ability to execute non-safety logic. This facility, for example, can be used to provide
a cost-effective solution for the implementation of an operator matrix panel.
