Siemens S7-300PLC communication module

Siemens S7-300PLC communication module point-to-point connection through the processor (CP) is a large and low-cost alternative to a centerline system. The point of a point-to-point link compared to a bus system is obvious when only a small number of (RS485) devices need to be connected to the SIMATIC S7. The CP makes it easy to connect third-party systems to the SIMATIC S7. Due to the nature of the CP, many different physical transmission media, transmission rates and even customized transmission protocols are possible. For each CP, we provide a configuration package and an electronic manual on CD-ROM, as well as parameterized screen forms and standard function blocks for communication between the CPU and the CP. The configuration data is stored in the system block of the CPU and backed up. Thus the new module can be put into operation immediately when replacing the module.The interface modules for the S7-300 are available in three versions, each with an interface for a different physical transmission medium.

Applications

The communication modules enable the SIMATIC S7-300 to be connected to e.g.:

- SIMATIC S7 and SIMATIC S5 programmable controllers, as well as systems from many other manufacturers

- PCs, programmable devices, HMI devices

- Field devices

- Printers

- Robot control

- Modems

- Scanners, barcode readers, etc.

Benefits

Reduced start-up time due to easy configuration using STEP 7

-Shortened downtime and maintenance in the event of a malfunction due to LED indication

Design and functionality

The CP has a reinforced plastic housing with LEDs for indicating operating and fault status. They demonstrate the full potential of the SIMATIC S7-300 design, such as .

-Compact design

-Easy installation

user-friendly wiring, etc.
