SIEMENS SIMATIC DP RS 485 – 6ES7972-0DA00-0AA0

Overview

Profibus Terminator is an active terminator created to make possible handling any communication bus node in full operation. Thus the nodes can be turned off, removed or replaced without harming the transfer of data from the other nodes. The devices on both ends of the net can be removed without affecting the intermediary nodes, whose termination ends must stay constantly turned on.

The Profibus DP Terminator can be mounted on standard 35mm DIN rail. An indication LED indicates the status of the 24V source and the correct bus operation.

The Power supply and the communication cables are connected by terminals with fixed screws and also the Profibus bus can be accessed by a DB9 connector.

Terminates bus segments at data transmission rates of 9.6 kbit/s to 12 Mbit/s
Power supply independent of bus stations.

Designed for Industry

Terminal-independent bus termination through onboard power supply

Application

The active RS 485 terminating resistor is used to terminate bus segments. The resistor is supplied with power independently of the bus nodes. The terminating resistor is hereby supplied separately from the other I/O components with a permanent voltage or with a voltage switched upstream of the I/O. By terminating the bus system, the nodes (e.g. ET 200SP) can be freely connected and disconnected without malfunctions.

Design

1 terminal block for the segment connection
Terminal block for power supply (24 V DC external)

Function

The active RS 485 terminating element terminates the PROFIBUS and therefore ensures a defined level of the RS 485 signal and suppression of reflections on the line. Since it is operated independently of the field devices, they can be decoupled from the bus without reactions.
