Token Watchdog Time
1
to
255
milliseconds
The
Token Watchdog Time
(also known as Token Monitoring Time) value is
unique for each node and is set from the FA link protocol upper layer as the initial
value. If this value is not set, the node is inoperable.
The
Token Watchdog Time
is notified to all nodes as information on the frame
header. Each node uses the value on the frame from each node as a value of the
monitoring time until the token-holding node releases the token.
Minimum Frame Interval Time
0
to
50
(in units of 100 milliseconds)
This interval value is a unique for each node and is set from the FA link protocol
upper layer as the initial value. If this value is not set, the node is inoperable.
The allowable minimum frame interval means
The time interval between reception of a token by a node and and
transmission of any frame from the node
or
The time interval between frames transmitted (from the end of the previous
frame until the beginning of the next frame) The allowable minimum frame
interval of each node is notified to all nodes as information on the frame
header. Each node obtains the maximum value from it and recognizes it as
the allowable minimum frame interval to use.
Important Note:
For this module to operate correctly on an FL-net network, the
Minimum Frame Interval Time
must be set to a value of
20
or more for all nodes
on the network. If nodes on the network have values less than
20
for this
parameter, the module may not be able to join the network.
