Siemens S7-300 PLC

SIMATIC S7-300

A graded CPU range with a wide performance range is available for configuring the controller. Thanks to their high processing speed, the CPUs enable short machine cycle times. The narrow module width results in a compact controller design or a small control cabinet.

The CPUs are available from a width of only 40 mm. Fail-safe CPUs are available for safety-oriented applications. The PROFIsafe profile for safe communication via PROFIBUS and PROFINET allows the integration of safety-related functions into standard automation environments.

Compact CPUs with width of 80 or 120 mm also offer integral I/O and integral technological functions. This onboard I/O (digital/analog) and the technological functions save additional investments in other modules.

Applications include the following:

High-speed counting/measuring with direct access to the hardware counter
Simple positioning with direct control of the MICROMASTER frequency inverter
PID control with integral function block

This range is rounded off by a special technology CPU with powerful technological function, especially for motion control.

Together with the integral digital I/O and equidistant and isochronous mode on PROFIBUS DP, off-the-shelf, PLCopen-compliant motion control of several (even linked) axes.

Micro Memory Card

The Micro Memory card is a compact medium that meets the highest industrial requirements, especially ESD protection and mechanical ruggedness.

The system-tested Micro Memory Card Allows more write cycles than conventional memory cards and offers know-how protection because the serial number can be read out.
