Chapter 1. Introduction
I/O Station Capacity
1.1
Network Topology
1.2
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.
Installation
1.3
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.
IOGuidePro Tool for Configuration & Monitoring

PACSystems RSTi Network adapters can be configured & monitored using IOGuidePro tool.
You can use the IOGuidePro Tool to monitor & configure the following data:

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
