The Simatic S7-1500 controllers from Siemens Industry (Chicago, IL) feature integrated motion control, security, and safety functions, as well as a color display. The controllers feature a backplane bus with a high baud rate and efficient transmission protocol, and have have two built-in, standard Profinet interfaces. The largest controller in the line has an additional Profinet interface onboard with a separate IP address, allowing network isolation to integrate into the corporate network.Standard motion control functions enable analog and Profidrive-compatible drives to be connected without additional modules. The controllers support speed and positioning axes, as well as encoders. The F-version (failsafe) function provides both standard and safetyrelated programs. The controllers are integrated into Siemens TIA Portal engineering framework that offers a standardized operating concept for controller, HMI and drives, shared data storage, and automatic data consistency.
