Replacement Procedure

9-2 Replacement Procedure

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."
DM 30000 + 100 × n
n = Unit number
−: Other settings
4. Restart the SYSMAC LINK Unit or turn ON the power again. Check that
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 (1) Stop the data links before restarting the SYSMAC LINK Unit. Check again
that the network parameters for the node that has been replaced are the
same as for the other nodes.
(2) When replacing the Unit, do not reconnect that node to the Network be-
fore carrying out the procedures listed below. 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 net-
work parameters in the entire Network will be damaged.
Note In CS-series SYSMAC LINK Units, data is stored in the battery-powered
backup SRAM in the CPU Unit. Consequently, a SYSMAC LINK Unit will func-
tion as before simply by making the appropriate hardware settings, even if it is
replaced. The data link tables and routing tables must be reset, however, if the
CPU Unit is replaced.
1. Turn OFF all the nodes in the SYSMAC LINK Network.
2. Disconnect the communications cable from the SYSMAC LINK Unit you
wish to replace, and remove the Unit.
3. Mount the new SYSMAC LINK Unit on the CPU Unit, and connect the com-
munications cable (refer to SECTION 2 Unit Components and Switch Set-
tings ).
4. Set the unit number, node address, and terminating resistance in the new
SYSMAC LINK Unit to the same as the previous one (Refer to SECTION
2 Unit Components and Switch Settings ).
5. Turn ON the power to all nodes in the SYSMAC LINK Network, except to
the CPU Unit for the SYSMAC LINK Unit that has been replaced.
6. Check that all other nodes are operating normally.
7. Read the network parameters using CX-Net in CX-Programmer, and check
that the network settings are correct.
8. Start the data links from the data link startup node if the data links do not
start automatically.
9. Check that the data links are operating normally using the data link status
monitor in CX-Net in CX-Programmer.

1: Polled node
