The CP 440 communications processor is used for high-performance transmission of short message frames via RS 422/RS 485 (X27). This is the preferred method for implementing point-to-point connections.

Point-to-point connection is possible, for instance, for:

• SIMATIC S7, SIMATIC S5 programmable logic controllers and third-party controllers
• Programming devices and PCs
• Robot controls
• Scanners, barcode readers
• Measuring systems
• Scales

The RS 485 interface supports links to up to 32 partners.
