2.26.2 CH, Enter/Change Data
2.26.2.1 Changing an existing PRR entry
In order to change data in a reaction entry it must first be selected via its "reason" and
entry number. If the entry exists, it is listed completely for checking at the operating
terminal.
The edit mode then becomes active, so that the user can modify or confirm each part of
the reaction entry step by step.
A reaction entry is not changed (and re-saved) in the system until every step of this
dialogue has been completed, i.e. after the last prompt for "Message Mask" has been
answered. In all other cases, e.g. if the dialogue is exited with CTRL/P or CTRL/E, any
changed data will be lost.
2.26.2.2 Creating a new process reaction entry
Depending on the type of reaction program, the following prompts must be answered in
order to create a new reaction entry:
Definition of the "reason"
User or technical address of the point triggering the reaction.
All
point types excepting CVP, PBN, PHON, TTY and RING are permissible triggers.
The VISONIK DCS sorts the reaction entries according to their "reasons" and
automatically allocates a number to each entry per "reason".
A reaction entry can only be identified unambiguously with its entry number.
As reason for the triggering points, different positive and negative edges can be defined.
A positive edge is:
–
Changes from normal to faulty
–
Changes from < LOL to Alarm
–
Changes from normal to > HIL
–
Changes from FL=1 to FL=2
–
Changes to “Frost IT” (OZ, ZON)
–
Changes to “Watchdog” (OS)
–
Changes to an OPSTA or ERSTA value to be defined
–
Change to a main value to be defined
