Disable Bit setting error.
The Unit is mounted to a
non-compatible PLC.
An error has occurred in
the PLC.
EEPROM error
The unit number is not set
in the range from 0 to 15.
The same unit number is
set more than once for the
same PLC.
I/O tables have not been
created for the PLC or they
are faulty.
Probable cause
---
If the ERC indicators still
lights when the Unit is
mounted on another PLC,
replace the Controller Link
Unit.
Check the power supply
voltage and supply at the
recommended voltage.
Secure the Controller Link
Unit firmly.
Refer to CVM1 and CV-
series PLCs and mount the
Unit correctly.
If the indicators do not light
when the Unit is mounted
in another PLC, replace
the Controller Link Unit.
Reset the node address to
within the 1 to 32 range.
Reset so that each node
address is used only once
within the same Network.
Remake and set the rout-
ing table correctly, referring
to 7-4 Setting Routing
Tables. When no routing
table is being used, set the
Routing Table Enable/Dis-
able Bit to OFF.
Refer to 1-2-4 Controller
Link Unit Models and PLCs
and reinstall the Unit on
the appropriate PLC.
Refer to the PLC’s opera-
tion manual and correct
the error. If the error occurs
again, replace the PLC.
Refer to 9-2 Status Area
and Troubleshooting, cor-
rect the data where the
error has occurred, and
reset the Unit. If the error
occurs again, replace the
Controller Link Unit.
Reset the Unit number to
within a range of 0 to 15.
Reset so that each unit
number is set only once
within the same PLC
(including the Expansion
CPU Backplane.)
Create I/O tables for the
PLC correctly.
