7.2.2 Confirming 262IF-01 Setting
The connection status can be checked based on the LED ON/OFF status and status information.
( 1 ) Normal Status
In the following status, link transmission takes place normally.
∗ 1. This status can be checked on the Status Detail Window (refer to page 4-10) for FL-net transmission definition.
∗ 2. This status can be checked from State of local node on the Status Tab Page (refer to page 4-12) for FL-net trans-
mission definition.
( 2 ) When Cyclic Transmission Is not Performed Normally
When cyclic transmission is not performed normally, check the following.

match those of the
other node.
Collect network configuration
information on the Network
Configuration Window for
FL-net transmission defini-
tion, check the common mem-
ory settings of the other nodes,
and then change the link
assignment.

Problems occurred
while receiving
transmission. (The
transmission interval
for all data, includ-
ing tokens, sent
from each node is
500
μs or less.)
Set the minimum permissible
frame interval to a value
greater than 500
μs on the
Transmission Parameters
Tab Page in the FL-net trans-
mission definition.

The setting value of
the token monitoring
time is smaller than
the actual refresh
cycle.
Change the token passing time
to the maximum value.
(Check the actual time from
the Refresh cycle time (max)
on the Status Tab Page in FL-
net transmission definition and
then change the token moni-
toring time to an adequate
value on the Transmisission
Parmeters Tab Page.)
