5.How to operate EX500 - GDN1 ( DeviceNet )

5-1. Connection style

DeviceNet unit can be connected by T branch, Multi branch and Branch line branch.

Total extension length of trunk and stay is different depending on communication speed and thickness of communication cable.

EX500 series can be connected only by T branch.
