Guidelines for I/OBus Networks

Overview	This section gives guidelines for creating an I/OBus network using a Momentum
	CPU as bus master.
Length
	The maximum distance between the Momentum CPU master and the farthest slave
	is 13 km (8 mi).
Distance
	The maximum distance between nodes is 400 m (1300 ft.).
Between Nodes
Number of
	A network may consist of as many as 256 nodes, including one Momentum CPU
Devices	bus master and up to 255 slave I/O devices.
	Note: Processors that support IEC are limited to a maximum number of 1408
	used I/O points, regardless of the number of modules.

Acceptable Slave An I/OBus slave device can be:

Devices

λA Momentum I/O base with a 170 INT 110 00 Interbus Communication Adapter mounted on it

λA Modicon Terminal Block I/O module enabled for Interbus communications

λA standard Interbus module designed by a third party manufacturer

Unacceptable The I/OBus network does not support Interbus-compatible devices that require the

Slave Devices Interbus PCP protocol.
