model.
The EM bank number for the LCB
registered at Net
@
, Node
@
is incor-
rect.
The EM bank number used by the LCB
is incorrectly set.
The EM bank numbers that can be used
by Loop Control Boards are 0 to C. Set
a number within this range.

registered at Net
@
, Node
@
is incor-
rect.
The HMI interface settings for the LCB
are not enabled.

Actual Unit Number is displayed in
the System Monitor Messages.
The actual Loop Control Unit’s address
and the node PLC’s Unit address in the
System Monitor Builder Screen do not
agree.
Make sure the actual Loop Control
Unit’s address and the System Monitor
Builder’s node PLC Unit’s address
agree.
ERROR CODE: is displayed during
Loop Control Unit Run/stop in the
System Monitor Screen.
The FinsGateway setting or the network
setting is incorrect.
Correct the FinsGateway setting and
the network settings.
An address error message is dis-
played on the System Monitor
