CS-series Optical Ring Controller Link Units Section 4-1
4-1-3 Setting the Node Addresses
Set the node addresses of each Unit on the network using the rotary switches
on the front of the Unit. When using Controller Link Units in duplex operation,
set the same node address for each active/standby pair of Units. The node
address is used to identify each node in the Network, and can be set to any
number between 01 and 62.
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
Note 1. When using Controller Link Units in duplex operation, be sure to set the
same node address for each active/standby pair of Units. If a different node
address is set, the Duplex Communications Unit Verification Error Flag
(A26112) will turn ON and an I/O table generation error will occur. It will not
be possible to create I/O tables using the Programming Device. At the
same time, a Duplex Communications Setting Error Flag will turn ON
(A43500 to A43515) will turn ON. (Bits 00 to 15 correspond to unit numbers
0 to 15.)
2. Always turn OFF the PLC’s power before setting the node address.
3. If there are no Units used in duplex operation, do not set the same node
address twice within the same network. A node address duplication error
will occur if the same address is set for two different nodes. The ERC indi-
cator on the front of the Unit will light (Communications Error Flag) and ei-
ther communications will stop, or the INS indicator will not light and the
node will be unable to participate in the network.
4. If there are Units used in duplex operation, the active Unit will enter the net-
work when the duplex settings have are made and the I/O tables recreated.
5. The send sequence for the data link areas is determined according to the
sequence of node addresses for automatically set data links.
6. Assign node addresses consecutively beginning from 01 whenever possi-
ble to minimize network construction time.
7. If there are Units used in duplex operation, the maximum number of actual
nodes allowable in the network will decrease by the number of standby
Units. There will be no effect, however, on the node address setting range.
4-1-4 Setting the Transmission Path Format
The transmission path format is set by a software switch allocated in the CPU
Unit’s DM parameter area. The same setting must be made for all nodes in
the network. Select either token-ring mode or token-bus mode by using a PLC
Programming Device (i.e., Programming Console, CX-Programmer, or SYS-
MAC Support Software) to set values for bits 9 and 8 in the software switch
shown below.
