Introduction 1
`Introduction
This manual describes the RSTi-EP remote I/O system. The products of the RSTi-EP series are
intended for use in industrial automation. A RSTi-EP station with network adapter and
connected modules is intended for the decentralized control of systems or sub-systems. Via
the network adapter every module of a station is integrated into a fieldbus structure and
connected to the primary control unit. The RSTi-EP products conform to protection class IP
20 (in accordance with DIN EN 60529), they can be used in potentially explosive
atmospheres rated as Zone 2 (as per Directive 2014/34/EU) and in safe zones.
The observance of the supplied documentation is part of the intended use. The products
described in this manual may only be used for the intended applications and only in
connection with certified third-party devices or components.
Introductory material may be found in this chapter along with a system overview.

Introduction 2
1.1 System Overview
The modular RSTi-EP system supports common fieldbus systems and conforms to IEC
61131-2. Each station is assigned a bus address in the fieldbus structure. Only the network
adapter is fieldbus-specific; the I/O modules are independent of the fieldbus.
Up to 64 active I/O modules can be combined in a RSTi-EP station. The largest expansion
possible depends on the maximum amount of data transmitted by the selected fieldbus,
the configuration, parameter, or process data for the module types provided. The
following components belong to the RSTi-EP product series:
•Fieldbus network adapter (gateway): Head station for converting the respective
fieldbus protocol on the RSTi-EP system bus
•Active I/O modules:
—Modules with digital input (DI) or digital output (DO) with 2, 4, 8 or 16
channels
—Modules with analogue input (AI) or analogue output (AO) with 4 or 8
channels
—Pulse width modulation modules (PWM)
—Digital counter modules (CNT)
•Passive I/O modules (no fieldbus communication)
—24 V power-feed modules (PF) for input or output current
—Potential distribution modules (AUX)
—Empty modules acting as placeholders (ES)
•Functional safety modules
—Safe power-feed modules (EP-19xx) 24 V for output current, providing one or
two inputs (with two channels each) for safety circuits
•Mechanical fixing elements
—End bracket
—End plate

Introduction 3
Double-click Installation
The RSTi-EP station modules can be installed quickly and simply. When attaching the
module to the DIN rail, a clear clicking noise can be heard, which means that the module has
clicked into place. In the second step, which involves pushing the module being installed
together with the neighboring module, a further clicking noise indicates that the modules
have been correctly connected to each other.
1.2 General Description of the Fieldbus Network
Adapters
A fieldbus network adapter is used to connect the station I/O modules to the fieldbus. All
the data traffic with the programmable logic controller including the diagnostic messages
is exchanged via the network adapter. The integrated power supply provides the network
adapter and all connected modules with power.
A detailed description of the individual network adapter types is available under Detailed
