Application Precautions Section 1-5
• Set routing tables at all the nodes in all the networks when multiple net-
works are connected.
• When using the SEND/RECV or CMND instructions on a PLC for which
routing tables have been set, be sure to specify the network addresses
that are set in the routing tables.
• When using manually set data links, delete the data link tables from all
nodes not participating in the data links.
• Do not transfer (write) routing tables when data links are active (i.e.,
started). CPU Bus Units and Communications Units are reset when rout-
ing tables are transferred.
• Do not restart or reset the polling node while data links are active.
• When an Optical Ring System is used, the same transmission path format
settings must be made for all of the nodes. The network cannot be set up
correctly if these settings are different.
• When Optical Bus (CLK11) and Optical Ring (H-PCF cable) (CLK12)
Controller Link Units are used in combination, the transmission path for-
mat for all of the Optical Ring Controller Link Units must be set to token-
bus mode. The network cannot be set up correctly if the mode settings
are different.
• When Optical Bus (CLK11) and Optical Ring (H-PCF cable) (CLK12)
Controller Link Units are used in combination, all of the node addresses
must be within the range of 1 to 32.
• When Optical Bus (CLK11) and Optical Ring (H-PCF cable) (CLK12)
Controller Link Units are used in combination, the software switch at the
Optical Ring Controller Link Units for selecting either polling node or nor-
mal node must be set for normal node. If the Optical Ring Controller Link
Unit nodes are set for polling when the network is started up, then the
maximum node address in the network parameters will be set to 62, and a
network parameter error (ERH indicator lit) will be generated at the Opti-
cal Bus Controller Link Unit nodes. If this occurs, use the Controller Link
Support Software (Ver. 2.00 or later) to set the maximum node address to
32.
• The Optical Ring (GI cable) Controller Link Units and Boards (CLK52)
cannot be combined with Optical Bus Controller Link Units (CLK11) or
Optical Ring (H-PCF cable) Controller Link Units (CLK12).
• When wiring using the ring method, it is recommended that the nodes be
connected in order (node 1
→
node 2...
→
node 62
→
node 1) to minimize
