4-3-12 Refresh Cycle Time (FL-net Unit to CPU Unit)
Determines the token frame transmission interval, which is the time measured
from when a token is sent until when it is received, and displays it in hexadec-
imal in units of 1 ms.
0000 to FFFF (Hex): 0 to 65,535 ms
4-3-13 Node Information (FL-net Unit to CPU Unit)
Note Nodes 250 to 255 are reserved for FL-net (Ver. 2.00) maintenance purposes.
• Indicates the network participation status between the local node and
nodes in the data link table settings that are registered in the other node
setup area (set using the CX-FLnet or FL-net Unit Support Software).
• When nodes registered in the data link table join the network normally
and the data link data from the nodes can be refreshed in the CPU Unit,
the corresponding bit turns ON.
• When communications from a participating node stop for three consecu-
tive communications cycles, the node is detected as not participating in
the network and the corresponding bit turns OFF.
• When the local node leaves the network, the corresponding bit for the
local node turns OFF, at which all bits including those for the local node
will turn OFF.
13 Common Memory Data
Validity Notification ON Valid ON when Common Memory data is valid.
Indicates that data from each node has started
being refreshed in the PLC.
OFF Invalid OFF when Common Memory data is invalid.
14 Common Memory Set-
ting Completed ON Completed Common Memory setting completed.
OFF Not com-
pleted OFF when error occurs in Common Memory
settings.
Correct the settings from the CX-FLnet or FL-
net Unit Support Software.
15 Duplicate Common
Memory Address ON Error ON when local node has same Common Mem-
ory address as a remote node.
The Common Memory address is the same as
that for a remote node that has already joined
the network. Correct the setting from the CX-
FLnet or FL-net Unit Support Software.
OFF Normal ON when local node does not have same Com-
mon Memory address as any remote node.
