Introduction 1
Chapter 1: Introduction
The PACSystems RSTi Network Interface and I/O family provides a cost effective, modular
distributed I/O system. The RSTi network is ideally suited for distributed applications such
as water/wastewater, process control, packaging and assembly. You can easily add RSTi
modules to the system to build functional remote I/O stations to meet your application
requirements.

A set of interconnected RSTi modules can be chosen to suit the application and connected
as a slave on a PROFIBUS or a PROFINET network. An RSTi Network Adapter provides the
interface between the network and the RSTi modules. The Network Adapter and I/O
modules selected for an application constitute an I/O station. The available network
adapters for various protocols are PROFIBUS, PROFINET, Modbus, DeviceNet, CANOpen and
CC-Link.
1.1 I/O Station Capacity
Up to 32 IO devices can be connected to a Network Adapter. The power consumption of all
the the modules in the node should be calculated and ensured that it does not exceed the
capacity of Network Adapter and power modules.
1.2 Installation
The Network Adapter must be connected to the left of the other RSTi modules in the I/O
station.
Within the RSTi station, the bus connection, power supply, and power distribution are
completed by connecting modules together on the DIN rail. Sensors and actuators are wired
to the RSTi modules using spring clamp terminals on the module’s removable terminal
strips. These terminal strips can be keyed so that they cannot be accidentally swapped. If a
module must be replaced, the wiring does not need to be removed; just remove the
terminal strip from the module.
RSTi Network Adapter with Integrated digital I/O is available. It combines the advantages of
slice-type and block-type construction and offers reduced system design and maintenance
costs.
1.3 Features
•Modules can be easily installed and connected without tools.
•Flexible and modular structure allows I/O stations to be easily expanded.
•A comprehensive selection of I/O modules supports a wide range of applications.
•Uses small removable terminal blocks to conserve panel space and save time making
system connections.
•Module-based diagnostic functions
•The amount of costly parallel wiring is reduced. Within a station, voltage and data
routing can be carried out without additional wiring, reducing the cabinet space
needed.

Introduction 3
•Different parts of the system can be operated independent of one another. This
means that pretests can be carried out when the system is set up and that the whole
system can be adapted and expanded
1.4 IOGuidePro Tool
