Configuring event monitoring
Event notification is a special application within the burst mod. When there are changes in the
device configuration or in the device status, an event notification is sent. This occurs regardless
of whether data is sent due to other burst mode commands. The status in the device status
byte, in the extended device status byte and in command 48 can be used for the event
notification. It is possible to define a certain number of bits that trigger an event notification.
Event notifications have a low priority. They nevertheless have a time stamp to record when a
notification was triggered the first time.
Up to 5 different event notifications can be defined.
The following list contains information about the structure of these input boxes and the format
in which you can enter information in these boxes.
WirelessHART Adapter SITRANS AW200
Operating Instructions, 02/2020, A5E02777161-AA
Meaning
Specifies the threshold value for changing from "update pe‐
riod" to "maximum update period": From the fast to the slow
setting and vice versa.
● The type of switchover is specified in the "message trig‐
ger mode".
Burst command number
● 1: Transfers the value of the primary variable and its unit.
● 2: Transfers the value of the 4 ... 20 mA signal and the
corresponding value as a percentage.
● 3: Transfers the value of the 4 ... 20 mA signal and up to
4 predefined dynamic variables ("primary variable",
"secondary variable", "tertiary variable", "quaternary
variable") and their unit
● 9: Transfers the value, the unit and the status of up to
8 field device variables.
● 33: Transfers the value and the unit of up to 4 field de‐
vice variables.
● 48: Transfers the entire device status.
Note:
1. Any commands can be set for connected field devices.
Refer to the relevant operating instructions.
2. If in doubt: Use command 3.
Selection of the device variables to be transferred with the
burst message, if command 9 or command 33 was selected
as the burst command number.
● Select the field device variable to be transferred from the
list (this is only possible for the WirelessHART adapter).
● If you want to set the burst for a connected field device,
check the operating instructions of the field device for
the assignment of device variables.
