Introduction
An event is a special message that is generated on the card
asynchronously. This means that it is not the response to a request
to the card, but a spontaneous message
What is the Goal?
The goal of events is to inform the environment about a changing
condition on the card. A message may be broadcast to mark the
change in status. The message is volatile and cannot be retrieved
from the system after it has been broadcast. There are several
means by which the message can be filtered
CDV29 Events
The events reported by the CDV29 are as follows;
Announcements
‘Announcements’ is not an event. This item is only used for
switching the announcement of status changes on/off. 0=off,
other =on
Analog_Inp1
Analog_Inp1 can be selected between 0 .. 255. 0= no event,
1..255 is the priority setting.
Analog_Inp2
Analog_Inp2 can be selected between 0 .. 255. 0= no event,
1..255 is the priority setting.
What information is
available in an
event?
The message consists of the following items;
1)
A message string to show what has happened in text, for
example: “INP_LOSS”, “REF_LOSS”, “INP_RETURN”.
2)
A tag that also shows what happens, but with a predefined
number: e.g. 1 (= loss of input), 2 (= loss of reference), 129(=
1+128 = return of input). For a list of these predefined tags
see the table on the next page.
3)
A priority that marks the importance of an event. This value is
defined by the user and can have any value between 1 and
255, or 0 when disabled.
4)
A slot number of the source of this event.
The Message String
The message string is defined in the card and is therefore fixed. It
may be used in controlling software like Synapse Set-up to show
the event.
