Note Nodes 250 to 255 are reserved for maintenance purposes for FL-net Ver. 2.00
specifications.
The network connection status of remote nodes is stored in the following bits.
Bits
15 11 07 03
14 10 06 02
13 09 05 01
12 08 04 00
1. Operation (Upper Layer)
The operating status (active/not active) of applications installed at the node
is stored.
2. Error (Upper Layer)
The error status (error/no error) of applications installed at the node is
stored. These bits turn ON when a fatal or non-fatal error occurs in each
PLC, or when the routing tables are incorrect.
3. Participation in Network
Network participation status is stored.
The operating status and error status data when not participating is invalid.
(The upper layer status when changing from participating to not participat-
ing is retained.)
4. Mapping Error
Notifies that the settings do not correctly reflect the network data in the
PLC areas.
The number of times ($0 to $FFFFFFFF) inconsistencies occur in parameters
in communications frames (CBN, TBN, and BSIZE) during cyclic transmission
reception is stored.
These errors may occur due to the network configuration. If this error occurs
frequently, either extend the minimum allowable frame interval using the CX-
FLnet or FL-net Unit Support Software or reduce the number of Units using
cascade connections from the hub.
