4-2-3 Setting the Node Address
Set the node address of each Unit in the network using the rotary switches on
the front of the Unit. The node address is used to identify each node in the
Network.
The node address can be set to any value between 01 and 62.
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
Note 1. Always turn OFF the PLC’s power before setting the node address.
2. 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 dif-
ferent nodes. The ERC indicator on the front of the Unit will light (Commu-
nications Error Flag) and either communications will stop, or the INS
indicator will not light and the node will be unable to participate in the net-
work.
3. The send sequence for the data link areas is determined according to the
sequence of node addresses for automatically set data links.
4. Assign node addresses consecutively beginning from 01 whenever possi-
ble to minimize network construction time.
4-2-4 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 CPU Bus Unit 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 SYSMAC Support Software) to set values for bits 9 and 8
in the software switch shown below.
When the transmission path format is changed, the change will not go into
effect until the PLC’s power is turned OFF and ON again or the Unit is
restarted.
