Troubleshooting with Indicators Section 10-1
Lit --- Flashing The Unit was removed because it was con-
nected to an FL-net (Ver. 1.00) network. FL-net Units (Ver. 1.00) cannot operate on
the same network as other FL-net Units.
Check the configuration of the network and
make sure it consists solely of compatible
FL-net Units.
Communications have stopped due to a
LAN controller error (LAN Controller Error
Flag: ON) Noise or other factor may be affecting net-
work communications. Check the ground-
ing of the network equipment and devices.
Restart the CPU Unit if this error occurs.
A PLC area cannot be accessed (data allo-
cation error). Re-check the system settings on the Unit.
Check to see if an area not in the PLC, an
unusable area (i.e., the number of EM
banks or where files are present), or an
area where data cannot be written is being
accessed.
Check that local node addresses are not
allocated in an other node setup area.
