Handling Precautions Section 10-7
this reason, temporarily set the replaced node’s polled/polling node setting
in the DM parameter area to a “polled node” after replacing the Unit.

CVM1 and CV-series Controller Link Units
2. Turn the power off once, connect the Controller Link Network and turn the
power on again. Check that the Unit is participating in the Network.
If the INS indicator is lit and the ERC and ERH indicators are off, then the
Unit is in the Network.
3. Return the polled node/polling node setting of the node in which the Unit
was replaced to “polling node.”

CVM1 and CV-series Controller Link Units
4. Restart the Controller Link Unit or turn the power off and then back on
again, and then check to see if the Unit is participating in the Network.
If the INS indicator is lit and the ERC and ERH indicators are not lit, then
the Unit is in the Network.
Note Restart the Unit only when the data links are halted.
Using the above procedure to reset the network parameters of the node that
was replaced to the same as the other nodes in the Network.
!Caution When a CPU Unit has been replaced for a CVM1 or CV-series Controller Link
Unit, do not connect that node to the Network before carrying out the above
procedures. In particular, a node with a small address will become the polling
node and communicate the initial network parameter status to other nodes, so
there is the chance that network parameters in the entire Network will be dam-
aged.
10-7-4 Replacing the Unit
CS-series, CVM1 and CV-series Controller Link Units
Note CS-series, CVM1 and CV-series Controller Link Unit data is stored in the
EEPROM of the CPU Unit. For this reason even if the Controller Link Unit is
replaced, on the hardware settings must be made to return all settings to their
previous status. If, however, the CPU Unit is replaced, the data link tables and
routing tables will need to be reset.
