The unique power supply concept, developed especially for use in hazardous areas, makes system planning as simple as for normal industrial I/O systems. Plug & play without separate engineering tools. IS1+ is particularly flexible: Suitable for small and big signal quantities with field stations installed in safe or explosive atmospheres. An intrinsically safe fieldbus using copper-wire or fibre-optic technology connects field stations in Zone 1 / Division 1 with the automation devices. The system is completely HART transparent. IS1+ is extremely economical: Modules with 8 or 16 inputs lower the price per signal. DTM technology is used for full integration into standard Asset Management and Engineering systems allowing easy and fast commissioning, trouble shooting and maintenance.

3 System Description CPU & Power Module I/O Modules The IS1 system provides a modern, cost-effective and flexible remote I/O system with intrinsically safe inputs and outputs, suitable for direct installation in hazardous areas. The uniform system concept permits installation in Zone 1 / Division 1, in Zone 2 / Division 2, Zone 21, Zone 22 and in a safe area. Suitable enclosures for different Zones, Classes and Divsions are available. Inputs and outputs are optimized for the sensors and actuators used in process technology. Plug-in terminals BusRail The integration of different fieldbuses permits digital communication with many automation systems. IS1 consists of three components: BusRail for the internal bus and for the power supply of the I/O modules CPU & Power Module for fieldbus communication and power supply I/O modules for the inputs and outputs of the process signals 05855E02 Configuration of a Field Station The I/O modules have 4, 6, 8 or 16 channels and can be plugged into any position on the BusRail. Addresses are assigned automatically. Rail segment I Link cable A BusRail can be mechanically distributed over several rail segments. Individual segments are connected by cable. An extensive range of field enclosures permits adaptation of the mechanical requirements of an application. Rail segment II 09864E02 Internal Bus CPU & Power Module The internal bus provides data exchange between the CPU & Power Module and the I/O modules. It is a component of the BusRail. I/O Module The I/O modules are addressed on the internal bus by means of the slot on the BusRail, so that an address setting is not necessary. The internal bus in the BusRail is designed to be redundant in all modules, so that even in the event of a fault the communication between modules is guaranteed. Internal Bus BusRail Redundant internal Bus 05856E02 Remote I/O /3

4 Redundancy The high system availability that is required for applications in the process industry is guaranteed through a proven redundancy concept. Various redundancy stages permit adaptation to the availability requirements of the user: Fieldbus cable redundancy (Line redundancy) CPU & Power Module redundancy (Full redundancy) The internal bus of an IS1 field station is always redundantly configured. Redundant CPU & Power Module Redundant fieldbus cable 07670E E02 Line redundancy Full redundancy Hot Swap Fieldbus plug connector CPU & Power Module I/O Module All modules in the IS1 system can be replaced at any time during station operation. This also applies for the Zone 1 / Division 1 CPU & Power Modules. The I/O modules are fitted with plug-in terminals for connection to the field cable so that the field wiring does not have to be disconnected when replacing a module. Plug-in terminals BusRail Plug connector on the BusRail 05858E02 When an I/O module is replaced, the CPU & Power Module automatically: Checks the type and version of the new I/O module Loads the current parameter set into the new I/O module Starts the new module When Profibus DP is used, the CPU & Power Module can also be replaced: Only fieldbus address must be set All configuration and parameter data are automatically downloaded into the new CPU & Power Module by the master via Profibus DP. /4 Remote I/O

5 Fieldbus The fieldbus is the connection between the CPU & Power Module and the automation system. Input and output data between the field stations and the automation equipment are exchanged over the fieldbus. Fieldbuses that can be connected: Profibus DP V0 and DP V1 HART, up to 1.5 MBit / s Modbus RTU, up to 38.4 kbit / s Industrial Ethernet / Modbus TCP Depending on the functionality of the fieldbus, the following functions are supported: Configuration of the IS1 field station or read back the configuration Load the modules with parameters Read/write input and output data Read the alarms and diagnostic data of a field station Transmit HART commands from / to field devices, read HART process value (PV1) and variables (PV2, PV3, PV4) The fieldbus is operated intrinsically safe for field stations in Zone 1 or Division 1. The fieldbus isolating repeater provides the intrinsic safety of a fieldbus segment. Several fieldbus isolating repeaters can be connected as repeaters to a fieldbus that is not intrinsically safe. An appropriate switch is used for Ethernet systems. A maximum of 31 field stations can be connected to an intrinsically safe RS 485-IS segment (Zone 1 / Division 1). A maximum of 32 devices (PLC, isolating repeaters, field stations) can be connected to an RS 485 fieldbus which is not intrinsically safe (Zone 2 / Division 2 or safe area). The number of field stations that can be addressed depends on the fieldbus protocol (e g. up to 126 with Profibus DP) E02 Service Bus The CPU & Power Module has, in addition to the fieldbus connection, an interface for the ServiceBus. Up to 128 field stations can be connected together via the ServiceBus. The network is configured so that, even if a field station fails, the data transmission from and to the other field stations is guaranteed. When used in Zone 1 / Division 1, the data are transmitted to the safe area through a common cable. The fieldbus isolating repeater, located in the safe area, is used as the interface between RS 485-IS and RS 232 / RS 485 signals. Remote I/O /5

6 Asset Management and HART The process value of a HART field device is always transmitted as an analog signal along with the ma signal. Moreover, the HART variables (P1... PV4) of the HART I/O modules can be read and transmitted in floating point format (4 Byte IEEE) in the cyclic data exchange (Profibus DP V0) to the automation system. The IS1 field station behaves transparently for the exchange of HART commands between IS1 and engineering stations. The transmission of HART commands occurs either via the ServiceBus or the fieldbus (Profibus DP V1 HART, Modbus RTU, Ethernet / Modbus TCP). 1 The following software packages can be operated on the ServiceBus (drivers are part of the software): Cornerstone by ASTEC AMS by Emerson Fieldcare by Endress + Hauser PDM by Siemens PRM by Yokogawa (from PRM-version ) FDM by Honeywell 2 The following can be operated directly on the Profibus: PDM by Siemens, an EDD (Electronic Device Description) is available for this purpose AMS by Emerson (from AMS-version 6.1) All FDT / DTM-based software packages, e.g. Pactware, Fieldcare from Endress + Hauser (a Device Type Manager, DTM, is available for IS1) 3 The following can be operated via a gateway and ethernet: AMS (for this purpose the Ethernet-Profibus interface from Trebing & Himstedt is necessary, e.g. xepi) Other software packages and gateways that offer connection possibilities to Profibus DP V1 HART 4 The following can be operated via a controller of an automation system (PLC, PCS) and the system bus: PDM, requires "routing-capable" components in the automation system (an EDD is available for this purpose) Others available on a per-order basis 09869E02 /6 Remote I/O
