Methods

Normal multi-drop, T-branch multi-drop (with up to three branches), and daisy-

chain line connections are available. These methods can be combined to con-

struct a flexible system that suits the floor layout.

Maximum Network Length

of 500 m

A network can connect up to 63 Slaves and can handle remote I/O communi-

cations of up to 2,000 byes (16,000 points without the Configurator) per

DeviceNet Unit. A maximum network length of 500 m is possible with a baud

rate of125 Kbps using thick cable.

High-speed

Communications

High-speed communications are possible at up to 500 Kbps for a trunk line

length of 100 m.

Compatibility with Slow

Slaves

The communications cycle time can be set even without the Configurator so

slaves with slow response times can be used.

A Wide Variety of Slaves A wide variety of I/O devices, like Remote I/O Terminals, Environment-resis-

tant Terminals, Remote Adapters, Sensor Terminals, Temperature Input Ter-

minals, CQM1 I/O Link Units, Analog I/O Terminals, C200H I/O Link Units,

RS-232C Units, MULTIPLE I/O TERMINALs, Temperature Adjusters, Invert-

ers, and Intelligent Plugs can be used as slaves.
