2 Safety Precautions
xxi
or the node address of the Component (DeviceNet Master/Slave or
CompoWay/F Slave), and be sure that these operations can be performed
safely for the current status of the node (Unit or Component):
•
Transferring parameter or program data to the other node
•
Changing the operating mode of the other node
Unexpected operation may result if parameter or program data is transferred
to the wrong node (DeviceNet Master/Slave, CompoNet Master/Slave or
CompoWay/F Slave), the operating mode of the wrong node is changed, or
the other node is not in a suitable status to receive the program or parameter
data or the operating mode change.
!Caution
When changing the target PLC to any PLC other than the relay PLC, check
the node address and node number of the target PLC carefully before
executing the change. Unexpected operation and injury may result if the
wrong PLC is set as the target PLC.
•
Changing the operating mode
•
Transferring or verifying user-set data link tables
•
Transferring or verifying routing tables
•
Performing I/O table operations (including transferring CPU Bus Unit or
Special I/O Unit parameters)
Note Operations performed from the CX-Integrator are performed for the target
PLC, which is not necessarily the same as the relay PLC.
!Caution When transferring parameters that have been created or edited on the
computer to actual Units (PLC CPU Bus Units or PLC Special I/O Units) or to
actual Components (DeviceNet Masters/Slaves, CompoNet Master/Slave
or CompoWay/F Slaves), always check the identifying number of the actual
Units or Components (i.e., the unit numbers and unit addresses or node
addresses) before executing the transfer. Unexpected operation and injury
may result if parameters are transferred to the wrong Unit or Component.
!Caution When changing or removing a routing table (see note), be sure to update the
display for the Online Connection Information Window. The display for the
Online Connection Information Window could possibly be different from the
actual network status. If operations are executed without first updating the
display, particularly online operations in the Network Configuration Window, it
could cause data to be mistakenly read or written for the wrong network or
node address or unit number.
Note: Changing or removing a routing table refers to using the
CX-Integrator (or a CX-Integrator for another personal computer) to
start the Routing Table Component and then changing or removing
a routing table for the target PLC (either a local network table or a
relay network table).
!Caution
Do not execute a broadcast node search if a node exists for something other
than an OMRON Ethernet Unit or FinsGateway within the same segment on
Ethernet, and when the Ethernet network system is in operation. When a
broadcast node search is executed, an OMRON FINS command is sent to all
nodes in the segment. Therefore, if a node exists for something other than an
OMRON Ethernet Unit or FinsGateway, the FINS command will not be
received at that node and unexpected operation may occur.
! Caution Confirm safety thoroughly in advance before transferring program data to
another node on the network or changing the I/O memory. Otherwise, injuries
may occur.
