Systems Wired with an Existing Repeater Unit
The power to the PCs of the segment
shown in the dot-dash broken line
does not need to be turned OFF.
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
(W467).
• If using the SEND, RECV, and CMND instructions with a PC on which the
routing tables have been set, be sure to specify the network address set
in the routing 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 network will not be configured correctly.
• Wired Systems cannot be used together with Optical or Optical Ring Sys-
tems.
• If using Optical System Units (model numbers ending in CLK11) and H-
PCF Cable Optical Ring System models (model numbers ending in
CLK12, CLK12-EV1, or CLK13-E) together, observe the following precau-
tions.
• 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.
• Set node addresses from 1 to 32 for all nodes.
• Set the polling node/polled node software switches for all the Optical
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 Parame-
ter Error (ERH) indicators on the Optical System Units will light.
• GI Cable Optical Ring System Units (model numbers ending 3G8F7-
CLK53-E, and 3G8F7-CLK52-EV1) cannot be used together with Optical
System Units (model numbers ending CLK11) or H-PCF Cable Optical
Ring System Units (model numbers ending 3G8F7-CLK13-E, and 3G8F7-
CLK12-EV1).
• 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
communication time if a wire breaks. For details on communications time,
refer to 8-2 Communications Cycle Time.
The power to the PCs in the
segment shown in the dash broken
line must be turned OFF.
