Description
This read-only field shows the number of
messages IEC62591 module has received from the
Field Link.
This read-only field shows the number of NACKs
the IEC62591 module has sent to the Field Link. A
NACK is typically sent when a received message
contains an error and a retransmission request is
sent. A high number of NACKs is often an
indication of a poor link connection.
Reserved
This read-only field shows the number of retry
requests the IEC62591 module has received from
the Field Link. A retry request is sent by the Field
Link when it does not receive an acknowledgement
from the IEC62591 module. A High number of
retries is often an indication of a poor link
connection.
This read-only field shows the number of Session
Initiates the IEC62591 module has received from
the Field Link. A Session Initiate is sent by the Field
Link when it wants to start and/or restart
communications with the IEC62591 module (for
example, after the Field Link (first powers up).
This read-only field shows the number of Session
Restart requests the IEC62591 module has sent to
the Field Link. A Session Restart request is sent by
the IEC62591 module to request a bus restart of
the communications with the Field Link (for
example, after the IEC62591 module first powers
up).
This read-only field shows the number of Set Time
messages the IEC62591 module has sent to the
Field Link. A Set Time message is part of the time
management process used to keep the
WirelessHART network time up to date.
This read-only field shows the number of Set Time
messages the IEC62591 module has received from
the Field Link.
This read-only field shows the number of Reset
APM messages the IEC62591 module has sent to
the Field Link. A Reset APM message is part of the
wireless management process used to restart the
WirelessHART radio on the Field Link.
This read-only field shows the number of Reset
APM messages the IEC62591 module has received
from the Field Link.
This read-only field shows the number of Tunnel
messages the IEC62591 module has sent to the
Field Link. A Tunnel message is part of the wireless
management process used to send information
across the WirelessHART network.
