2.32.2 CH, Enter/Change Data
2.32.2.1 Changing an existing TRR 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.
2.32.2.2 Creating a new time reaction entry
Depending on the type of reaction program, the following prompts must be answered in
order to create a new time reaction entry:
Definition of the "reason"
Two different entries can be made in TRR for the "Time=" question:
–
Time of day when the reaction should be executed
–
A full stop "."
The TRR entry has no time as yet. This can be added later.
If the reaction is a point address, e.g., "Reaction=a01b2SB", then the time can be
added in Ctrl/V mode.
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.
The day of the week that the reaction should be executed.
