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.
