The ET 200iSP is a modular, intrinsically-safe I/O system with IP30 degree of protection which can be operated in gas and dust atmospheres at ambient temperatures from -20 to +70 °C. It is optimized for use with SIMATIC PCS 7 and SIMATIC S7, but can also be integrated in other systems such as SIMATIC S5 per GSD file.
In accordance with ATEX directive 2014/34/EU, the ET 200iSP remote I/O stations can be installed directly in Ex Zones 1, 2, 21 or 22 as well as in non-hazardous areas. The intrinsically-safe sensors, actuators and HART field devices can also be located in zone 0 or 20 if necessary.
The modular design of the ET 200iSP makes it possible to optimally adapt the remote I/O stations to the respective automation task through individual configuration and flexible expansion. To increase plant availability, the pressure-encapsulated power supply and the intrinsically-safe PROFIBUS DP connection (RS 485-iS) of the stations can also be of redundant design.
The modern architecture with hardwiring and automatic slot coding supports pre-wiring without the electronic modules, simple and reliable hot swapping of individual modules without a fire certificate as well as configuration in run (CiR).
In addition to analog and digital I/O modules for the automation of technological functions of the process (Basic Process Control), the range of electronic modules also includes fail-safe I/O modules for implementing safety applications. The various types of electronic module can be arranged mixed within a station. Comprehensive diagnostic options facilitate commissioning and troubleshooting.
Main components of the ET 200iSP distributed I/O system:
Assembly is quick and easy:
The station width is 107 cm in the maximum configuration with 32 electronic modules.
The maximum number of electronics modules which can be used per station may be limited depending on the current consumption of the modules required to solve the automation task. However, up to 16 electronics modules can be used without limitation.
If the ET 200iSP is used in a hazardous area, it must be installed in an appropriate Ex housing which at least corresponds to the IP54 degree of protection. Appropriate versions of an IP65 housing are offered in the Section “Stainless steel wall housings”.
Distributed ET 200iSP remote I/O stations are connected to the automation systems (controllers) via the PROFIBUS DP, which can be routed intrinsically-safe into Ex‑zone 1 using an isolating transformer (RS 485‑iS coupler) as barrier. Data transfer rates of up to 1.5 Mbps are possible. The ET 200iSP remote I/O stations can be connected to the controller as DP V0 slave or DP V1 slave.
The ET 200iSP remote I/O stations are integrated into the SIMATIC PCS 7 process control system using standard driver blocks.
The existing standard diagnostics drivers process the diagnostics messages generated by internal or external faults (e.g. wire breakage or short-circuit) as well as status messages of the connected HART field devices for the host operator system and the SIMATIC PCS 7 maintenance station.
Vendor-specific information and maintenance data are saved powerfail-proof on the electronics modules.
The ET 200iSP stations can be configured and parameterized per HW Config in a SIMATIC S7/SIMATIC PCS 7 environment. Parameters of the ET 200iSP stations and the HART field devices can also be set using the process device manager, SIMATIC PDM. Routing via PROFIBUS DP enables direct access to the HART field devices on the ET 200iSP with SIMATIC PDM.
The system function CiR (Configuration in Run) is also supported for the configuration of SIMATIC PCS 7 and permits the following changes to be made to the configuration during runtime:
The station design (configuration) should be published over the PROFIBUS DP network per GSD file.
Process Device Manager SIMATIC PDM is required for the configuration. It can be used to define, for example, alarm limits for analog modules, signal encoders for digital modules as well as settings for outputting analog values and HART commands for analog HART modules.
