Network Configuration
Determining the Location of the Master
Note Do not strip too much insulation and shielding from the cable. Removing too
Allow about 10 cm between the wiring duct and nodes so that the nodes can
be wired without straining the connectors. Communications errors may occur
if there isn’t enough slack in the cable and the connectors are pulled out.
much shielding will provide a path for noise to enter the network.
Using Special Flat Cable makes it easy to extend a branch cable using one-
touch connectors, but Special Flat Cable cannot be combined with a trunk line
consisting of Special Thin/Thick Cable. There are differences between Spe-
cial Thin/Thick Cable and Special Flat Cable in terms of maximum network
length, branch line length, and current capacity. For detailed specifications,
refer to 2-2-2 Trunk Lines and Branch Lines.
It is not necessary to locate the Master at the end of the network. The Master
can be located at any node position on the trunk line or a branch line.
Configure the network as desired, since there is no restriction on the Master’s
location.
