Distributed I/ODistributed automation is becoming increasingly widespread. More stringent demands for cost savings, less wiring and risk minimization are all important reasons for implementing distributed automation solutions.SIMATIC ET 200 systems offer solutions to IP20 degree of protection as well as to IP65/67 degree of protection for implementation in PROFINET. Line topologies can be easily formed using the integrated 2-port switch.
SIMATIC ET 200S is a finely modular, distributed I/O system to IP 20 degree of protection. The comprehensive module spectrum supports a range of uses: The right solution is available for any requirements – Whether analog signals, failsafe modules, counters, serial interfaces, motor starters, frequency converters or pneumatics Communication can take place over PROFIBUS or PROFINET - and it can be standard communication or safety-related communication - both is possible on one and the same cable
The PROFINET interface modules IM 151-3 PN STANDARD and HIGH FEATURE can be used to connect the multifunctional I/O system SIMATIC ET 200S to PROFINET to the iP20 degree of protection. The HIGH FEATURE variant supports PROFIsafe applications. Line topologies can be easily formed using the integrated 2-port switch. The frequency converter
The PROFINET interface module IM 151-3 PN FO can be used to connect the SIMATIC ET 200S product family to an optical PROFINET network through the integrated POF interfaces (Polymer Optic Fiber). The line topologies familiar from established field buses can be easily formed using the integrated 2-port switch. This means that safety-oriented PROFIsafe modules can also be connected to ET 200 with a direct fiber optic cable connection for the first time.
The IM151-8 PN/DP CPU has a PROFINET communication interface (with 3 ports for line structure and PG function) on-board and can optionally be expanded with a PROFIBUS-DP master module. The IM151-8 PN/DP CPU is based on the S7-300 CPU 314 and supports the real-time features RT and IRT (isochronous real-time). IRT enables extremely short, predictable reaction times, even faster, deterministic data exchange with IO-devices as well as a robust, reliable communication of the process data - also with very high non-realtime data traffic. The fail-safe version IM151-8F PN/DP F-CPU is based on the S7-300 CPU 314. Fail-safe as well as standard IO modules can be used. The communication between CPU and fail-safe modules is done via PROFIsafe.
For the interface module IM 154-4 PN HF, interface module and connection module have been separated, so that different connection techniques can be used:
CPU funktionality is available with the interface module IM 154-8 PN/DP. It is based on the CPU 315-2 PN/DP and offers the same quantitative framework and functions. The IM154-8 PN/DP CPU has two communication interfaces, a combined MPI/PROFIBUS DP interface and a PROFINET interface with three ports.
The IM 153-4 interface module for connection to PROFINET has an interface with integrated 2-port switch and T functionality for voltage supply. Thanks to the new 64-channel modules (64DI/DO) the channel density in the station is increased and enables the user to reduce the amount of space required in the cabinet.
