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.

Introduction 2
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.
1.1 I/O Station Capacity
•Up to 32 IO devices can be connected to a Network Adapter (STXPBS001,
STXPNS001) whereas. PROFIBUS network adapters with integrated IO support only
up to 8 IO modules. The power consumption of all the modules in the node should
be calculated and ensured that it does not exceed the capacity of Network Adapter
and power modules.
•The sum of all input and output data can be up to:
—504 bytes per station for a PROFINET network
—256 bytes / 72 bytes per station for a PROFIBUS network (for STXPBS001, 256
bytes and for STXPBS with Integrated IO, 72 bytes)
•The maximum number of I/O stations per RX3i PPROFINET controller is 128 and for
Rx3i PROFIBUS Controller is 125
1.2 Network Topology
For PROFIBUS networks, I/O stations can be connected via linear bus architecture with active
bus termination at both ends. Devices in a PROFIBUS network connect directly to the bus
cable or indirectly via stub lines.
For PROFINET networks, I/O stations can be connected using either linear or star
architecture.
1.3 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 PROFIBUS 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.

Introduction 3
1.4 I/O Guide Pro Tool for Configuration &
Monitoring
PACSystems RSTi Network adapters can be configured & monitored using I/O GuidePro tool.
You can use the I/O GuidePro Tool to monitor & configure the following data:
•Online monitoring & configuration of MODBUS serial & TCP Network adapters.
•Offline configuration of PROFIBUS, DeviceNet & Ethernet/IP Network adapters.
•RSTi Network adapter & IO node over view.
•Power consumption details.
•O module configuration parameters & memory map.
•RSTi Network adapter & IO module technical help.
For more information refer the help section of I/O GuidePro tool.
1.5 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.
•Small removable terminal blocks 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.
•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.

Chapter 2: Installation
WARNING
•Installing or removing modules or wiring with power applied to the system or field
wiring can cause an electrical arc. This can result in unexpected and potentially
dangerous action by field devices. Arcing is an explosion risk in hazardous locations.
Be sure that the area is non-hazardous or remove power appropriately before
installing or removing modules or wiring.
•Potentially dangerous voltages are present on a module’s terminals, even when
system power is turned off. Field power must be turned off when installing or
removing a terminal block assembly.
•Personnel, who install, operate and maintain automation systems that contain these
products must be trained and qualified to perform those functions.
•Overloading power modules or Network adapter can result into electric arc and
damage to modules.
CAUTION
•Check the rated voltage and terminal array before wiring.
•Ensure that specified environmental conditions are not exceeded. Avoid placing the
module in direct sunlight.
•Review module specifications carefully and ensure that input and output
connections are made in accordance with the specifications.
•Use specified cables for wiring.
•Field power isolators must be used according to the requirements of the
5VDC/24VDC/48VDC or AC voltage modules used in the system.
•If system power consumption exceeds the power limits, use system power
expansion modules.
•Power supplies for system power and field power must be supplied from separate
sources.

Release the DIN rail locking clip by pulling clip downward with a small-bladed screwdriver.
The clip will click and lock into the open position. Install the module on the DIN rail firmly.
Once module is in place on the DIN rail, push the clip upward to secure the module on the
DIN rail. To remove, pull clip downward until the locking clip clicks and locks, the module
can now be removed from the DIN rail.
Note: Make sure that the locking clip is in the upward position to ensure the module is properly
grounded and secured to the DIN rail.
