Only)
Cables
Baud Rates (Wired
Systems Only)
Routing Tables
Data Links
Others Precautions
Turn ON the terminating resistance switch only for the nodes at both ends of a
wired Controller Link Network and turn OFF the switch for all other nodes.
Note Refer to 2-1 Installing the Support Board.
Turn OFF the power of all the nodes on the network before connecting or discon-
necting a cable.
Note Refer to 2-2 Wiring.
Use the specified cable only.
Note Refer to 1-2 Specifications and Configurations.
In a wired Controller Link Network, set the same baud rate for all nodes on the
same network.
Note Refer to 3-2 Installation Method .
When a CV-series PC is connected to the network, set routing tables at all the
nodes.
Note Routing tables are not required if all the CV-series CPU Units in the Controller
Link Network have been manufactured on or after May 1996. The manufacturing
date can be determined from the four-digit lot number on the side of the CPU
Unit.
Lot No.:
Set routing tables at all the nodes in all the networks when multiple networks are
connected by a CV-series PC.
Note Refer to Section 8 Network Interconnections .
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 (clkopen) for three seconds after clos-
ing the Board (clkclose).
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 (clkcmd or driver call function code: 07 HEX).
The Controller Link Support Board can be used only with the specified operating
systems.
Note Refer to 1-2 Specifications and Configurations.
Set the memory area and interrupt level of a Controller Link Support Board so
that they do not overlap with other resources.
Note Refer to 2-1 Installing the Support Board, 3-2 Installation Method .
