If the burst messages being dropped are for a wired Sub-device, ensure that there are
no other HART masters on the connection, as these can cause burst message delays.
Timestamps:
Start: Set when the first HART Burst packet was dropped
Stop: Set when the last HART Burst packet was dropped
ALERT – Field Device Power Control
Description:
The field device power control mode is set to Switching, however the burst / event
configuration will keep the device always powered on.
Corrective Action:
If the Field Device Power Control Mode – Switching is not required, change this option.
Else, reduce the burst times for the wired Sub-devices such that the system will switch
the power to the devices. Check the “Field Device Estimate On Percentage” for an
estimated duty cycle that the Field Devices will be powered on for. This alert will be set
whenever this value is 100% and the Field Device Power Control Mode is set to
Switching.
Timestamps:
Start: Set when the Field Device Power Control issue is first detected
Stop: Set when the Field Device Power control issue is corrected
ALERT – Wireless Capacity Denied
Description:
The WirelessHART network has denied a request for Wireless bandwidth.
Corrective Action:
Check the burst mode settings for the device and reduce the requested bandwidth.
Timestamps:
Start: Set when the WirelessHART Network first denies bandwidth
Stop: Set when the WirelessHART Network grants bandwidth
