The SIMATIC ET 200AL is designed specifically for distributed control system applications in tight spaces. The SIMATIC ET 200AL series devices are easily configured, run via TIA Portal. The modules can be connected to the automation network via PROFINET, PROFIBUS interfaces or can be connected via ET 200SP.

The SIMATIC ET 200AL 157-1 PN – 6ES7157-1AB00-0AB0 modular I/O system has many practical advantages to offer thanks to which it is well suited for systems of many decentralized applications. The ET 200AL’s standard digital outputs can be switched off securely within the power system to ensure effective integration of safety applications up to SIL CL 2 or Cat 3/PL. Since only the outputs are disabled, diagnostics are still possible. With a high IP65/67 rating, particularly compact design, small space requirements and weight, this makes the ET200AL system ruggedly easy to use and install I/O for use anywhere.

Unified engineering with TIA Portal enables consistent system diagnostics and efficient operation. With the TIA Selection Tool, each ET 200AL system is configured and ordered quickly and conveniently. Other tools, such as SIMATIC Automation Tool, support the user during startup, maintenance and service, as well as configuration management.

The SIMATIC ET 200AL modules, which are only 30 or 45 mm wide, can be easily installed in any position in a machine or assembly line. An optional operating system allows you to add individual system components according to your installation requirements and individually configure the machine as required. This is achieved through a one-time full configuration and activation of the installation components via software. All functions that are not needed remain inactive. Sensors and actuators can be connected using reliable M8 and M12 connection technology. Color-coded sockets and matching connection cables simplify wiring. The modules are IP65/67-compliant. They operate reliably in a temperature range of -30 °C to +55 °C and at accelerations of up to 5 g. Since plastic housings provide low weight, SIMATIC ET 200AL modules are ideal for mobile applications.

The interface module IM 157-1 PN for SIMATIC ET 200AL, for connection to PROFINET, thanks to its solutions, has to offer a range of practical possibilities like: Automatic commissioning through topology detection, real-time RT and IRT properties , automatic crossover, MRP, MRPD, Data I&M, assignable to different processors through shared device and PROFIenergy.
