Overview

One of the most important advantages of the SIMOREG 6RA70 is that is is equipped with serial interfaces and another is that the SIMOREG converters can be easily integrated into the world of automation. This also applies to the AC drive product range from Siemens that utilizes many identical communication boards, simplifying implementation and reducing your spare parts inventories on site.

The addition of easily installed communication boards allows a wide range of communications possibilities to be configured. The SIMOREG 6RA70 is therefore able to communicate using many different protocols.

• SIMOLINK fiber-optic network with peer-to-peer functionality for extremely high-speed data exchange (11 Mbaud)
• PROFIBUS-DP communication
• Communication by means of CAN protocol
• DeviceNet communication

All SIMOREG 6RA70 converters are equipped with two serial interfaces as standard that are not only USS-capable but which also feature peer-to-peer functionality for baudrates of up to 187.5 Kbaud. There is a choice of RS 232 and RS 485 transfer format for the first serial interface. The interface is located on the front of the unit and an OP1S or PC (with DriveMonitor or Drive ES) can be easily connected to it. The second interface is a dedicated RS 485 interface that is located on the terminal strip of the CUD1.

An additional RS 485 interface is available on the optional terminal expansion board CUD2. The USS protocol is a proprietary Siemens protocol for drive systems. It enables up to 31 stations to be connected via the bus on the basis of RS 485 transmission. The data are exchanged in accordance with the host/slave access mechanism. The host can be a higher-level system such as a SIMATIC S5 or S7, a PC or a non-Siemens automation system.
