The parameter “I-Am-Alive time” serves for W-Master and W-Device
communication control if no other messages are transmitted. The W-Device
has to send an “I-Am-Alive” messages to the W-Master before timeout,
otherwise an error is reported, e.g. to start failsafe functionalities in the
application.
The “I-Am-Alive time” is calculated by multiplying the "Time base" with the
"Multiplier".
The Wireless Master verifies the calculated “I-Am-Alive time” with the
following limits:
·
“Minimum I-Am-Alive time” = W-Sub-cycle duration [ms] * (Ma
1)
If the calculated “I-Am-Alive time” is less than the “Minimum I-Am-Alive
time”, the Wireless Master uses the “Minimum I-Am-Alive time” as
resulting “I-Am-Alive time”.
·
Maximum I-Am-Alive time = 10 minutes
If the calculated “I-Am-Alive time” is greater than the “Maximum I-Am-
Alive time”, the error message
Port configuration failed HTTP

appears.

appears and a green hook
appears for the selected
port in the left column of the netFIELD Wireless Web Server, indicating
that a connection from an IO-Link Device to this wireless IO-Link port
has been established, and that the IO-Link Device is in “operate” state.
Note:
The green hook icon disappears if the IO-Link Wireless Master
changes to an error state but the device connection is still
established and in "connected" state (shown on top left corner of
the netFIELD Wireless Web Server). If the device connection drops
and the "disconnected" state is shown, the green hook icon is still
visible and reflects the latest status obtained from the device.
