Applications Precautions
Data Links
Others Precautions
When a routing table is transferred (written) to a PC, all CPU Bus and Commu-
nications Units are reset. The routing tables must not be transferred to a PC
while the system is running.
When using a manually set data link, delete the data link tables from all nodes
not participating in the data link.
The polling node must not be restarted or reset during data link operation.
If the Controller Link Support Board is the polling node and data links are operat-
ing on the network, do not open the Board for three seconds after closing the
Board.
If the Controller Link Support Board is the polling node and data links are operat-
ing on the network, do not add the Board to the network for three seconds after
leaving the network.
Observe the following precautions.
• The Controller Link Support Board can be used only with the specified OS.
Note Refer to 1-2 Specifications and Configurations.
• Set the IRQ (interrupt request) of the Controller Link Support Board so that it
does not overlap with other resources.
Note Refer to the Controller Link Support Board Installation Guide (W388).
• CX-Net in CX-Programmer V1.jj can be used only with systems with a maxi-
mum of 32 nodes (i.e., node addresses 1 to 32). If using node addresses from
33 or higher, use the Controller Link Support Software (Ver. 2.00 or later).
• If using the SEND, RECV, and CMND instructions with a PC on which the rout-
ing tables have been set, be sure to specify the network address set in the rout-
ing tables.
• If using an Optical Ring System, the same type of transmission path must be
set for all nodes. If the transmission path node settings are different, the net-
work will not be configured correctly.
• Wired Systems cannot be used together with Optical or Optical Ring Systems.
• If using Optical System Units (model numbers ending CLK11) and H-PCF
Cable Optical Ring System models (model numbers ending CLK12) together,
the transmission paths for the H-PCF Cable Optical Ring System Units must
be set to Token Bus Mode for all nodes. If the transmission path settings are
different, the network will not be configured correctly.
• If using Optical System Units (model numbers ending CLK11) and H-PCF
Cable Optical Ring System Units (model numbers ending CLK12) together,
set all the node addresses between 1 and 32.
• If using Optical System Units (model numbers ending CLK11) and H-PCF
Cable Optical Ring System Units (model numbers ending CLK12) together,
set the polling node/polled node software switches for all the H-PCF Cable Op-
tical Ring System Units for the polled node. If an optical ring node is the polling
node when the network is started, the maximum node address in the network
parameters will be set to 62, and the Network Parameter Error (ERH) indica-
tors on the Optical System Units will light.
If an Optical Ring System Unit becomes the polling node by mistake and the
maximum node address is set to 62, correct the maximum node address to 32
using the Controller Link Support Software (Ver. 2.00 or later).
• GI Cable Optical Ring System Units (model numbers ending CLK52) cannot
be used together with Optical System Units (model numbers ending CLK11) or
H-PCF Cable Optical Ring System Units (model numbers ending CLK12).
• If using ring wiring, connect the nodes in node address order (i.e., node 1, node
2.... node 62, node 1) as much as possible to reduce the effect on communica-
tion time if a wire breaks. For details on communications time, refer to 8-2
Communications Cycle Time.
