Active Advertising; Decommissioning Or Replacing Wireless Devices - Emerson IEC 62591 Instruction Manual

IEC 62591 Wireless Interface Instruction Manual (for ControlWave Micro)

3.3.1 Active Advertising

3.4 Decommissioning or Replacing Wireless Devices

3-18
Note: The Field Link only detects those wireless devices that you have
already individually configured with a unique long tag name, a
common Network ID, and common Join Key. You perform this
configuration separately using Field Tools' AMS Device
Configurator and a HART modem (or using an Emerson 375/475
Field Communicator). For information on configuring these
devices using the AMS Device Configurator, see the Emerson
Field Tools Quick Start Guide (part D301703X412).
The Field Link detects any configured wireless devices and reports them
to the IEC 62591 module.
The executing program adds these devices to the Active List, and
checks for each device to see whether a matching device tag exists in
the Commission List. Each device that has a matching tag along with an
ibDecommission flag set to FALSE automatically becomes an active
commissioned device in the network.
In addition to the normal mode for detecting wireless devices, the
system supports active advertising. In active advertising, the IEC
62591 module sends messages to the wireless network to keep radios
active for a longer period of time to facilitate quicker detection of new
(or replaced) wireless devices. Because leaving radios on consumes
power, active advertising is only used under certain conditions:
▪ When the IEC 62591 module is first powered on, or is restarted after
being powered off, it automatically remains in active advertising
mode for a period of time to detect wireless devices.
▪ Whenever a new device is added to the network, active advertising
is activated for a period of time in case additional devices are also
added.
▪ Whenever a device leaves the network (becomes unreachable) active
advertising is activated for a period of time to allow
communications to be re-established.
▪ Beginning with ControlWave firmware version 5.70, the application
programmer can force active advertising using the ioaiMode
parameter in the IEC62591 function block. See the ACCOL3 online
help in ControlWave Designer for details.
If you want to temporarily remove a wireless device from the network,
modify the ControlWave project to edit the Commission List and set the
ibDecommission flag for that device to TRUE, then compile and
download the revised project.
If you want to permanently remove a wireless device from the network,
modify the ControlWave project to remove the device from the
Commission List, then compile and download the revised project.
