GFK-2958E RSTi-EP User Manual November 2017 7
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. Chapter 2 provides
information about safety. Chapter 3 provides configuration instruction. Chapter 4 provides detailed
descriptions of the network adapters. Chapter 5 provides detailed descriptions of the I/O modules.
Chapter 6 provides information on installation and setup. Chapter 7 provides information on earthing
and shielding. Chapter 8 provides information on commissioning. Chapter 9 covers the Web Server.
Chapter 10 provides detailed instructions for replacing components. Chapter 11 describes
disassembly and disposal of the RSTi-EP station. Chapter 12 covers the LEDs and troubleshooting.
Chapter 13 provides ordering information for accessories and replacement parts. Appendix A is a
decimal/hexadecimal conversion table.
Caution
Prior to hot-swapping I/O modules, refer to section Replacing the
Electronic Unit.

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, in particular 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:
oModules with digital input (DI) or digital output (DO) with 2, 4, 8 or 16 channels
oModules with analogue input (AI) or analogue output (AO) with 4 or 8 channels
oPulse width modulation modules (PWM)
oDigital counter modules (CNT)
•Passive I/O modules (no fieldbus communication)
o24 V power-feed modules (PF) for input or output current
oPotential distribution modules (AUX)
oEmpty modules acting as placeholders (ES)
•Functional safety modules
oSafe 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
oEnd bracket
oEnd plate

1.2.1 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.

1.3 General Description of the Fieldbus Network Adapters
A fieldbus network adapter is used to connect the station I/O modules to the fieldbus. All of 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 in Chapter 4, Detailed
Descriptions of the Fieldbus Network Adapter.

1.5.1 Standard Connector
The connection frame can take up to four connectors, and four conductors can be connected to
each connector. Spring-style technology allows for fine-wired conductors with crimped wire-end
ferrules or ultrasonically welded conductors, each with a maximum cross-section of 1.5 mm², to be
inserted easily through the opening in the clamping terminal without having to use tools. To insert
fine-wired conductors without wire-end ferrules, the pusher must be pressed in with a screwdriver
(refer to the section, Wiring).
