Guidelines for I/OBus Networks
Overview
This section gives guidelines for creating an I/OBus network using TSX Momentum
components.
Network Scheme
Physically, the bus looks like a tree with the master at the head and the slaves
distributed along a trunk (see below).
Slave Devices
An I/OBus slave device can be:
A Momentum I/O base with a 170 INT 110 00 Interbus Communication Adapter
mounted on it
A Modicon Terminal Block I/O module enabled for Interbus communications
A standard Interbus module designed by a third party manufacturer
I/OBus
Restrictions
The I/OBus network does not support Interbus-compatible devices that require the
Interbus PCP protocol.
