Q1
If the status to be signalled ends before the minimum pending time
has elapsed, the counter will be set to 0 but the message will not
begin.
The counter always shows 0 if a minimum pending time has not been
assigned to a single message. In this case the message begins
immediately after the status to be signalled has been detected.
However, it depends on its state (disabled / enabled) whether a single
message is being routed at all: If a single message has been
disabled, the entire subsequent message processing considers it as
not pending.
Tip:
The main advantage of the
Groups
–
View
menu described here
is the possibility to analyse the status of a group and the single
messages contained therein. This menu only provides information but
does not allow to change the properties of a single message, for
instance to set a disabling mark. For this purpose the
Single
messages
menu must be invoked. The display of this menu is
structured similar to the one described above.
Single messages
The
Single messages
menu refers to the message processing of the
monitoring module. It does not only serve to indicate basic information
relating to single messages but also provides the possibility to disable such
messages via the operator panel of the device and to change limit values for
single messages of the measurement monitoring.
In order to switch to the display of another single message you have to get
into the edit mode (by pressing the Enter key) and select the name of the
message you want to view from the appearing list. Confirm your choice by
pressing the Enter key again.
The
Single messages
display is basically identical with the display of the
Groups
–
View
menu described above.
The parameterised limit value is indicated as additional information in case
of a message derived from measurement monitoring.
