6ES7972-0AA02-0XA0 is a Siemens RS485 repeater used to connect Profibus/SPI bus systems. The relevant introduction is as follows:
1.Functional Features
Signal transmission and regeneration: It can achieve the regeneration of signal amplitude and time, ensuring the stability and
reliability of signals in long-distance transmission or complex network environments. It can effectively extend the transmission
distance of the bus, increase the number of stations (up to 127) and coverage.
Electrical isolation: The electrical isolation function of the connected bus system physically isolates different network
segments. When a fault occurs in one network segment, it can prevent the fault from spreading to other network segments, improving
the stability and anti-interference ability of the system.
Automatic detection of transmission rate: The transmission rate can reach 9.6kbit/s to 12Mbit/s, including 45.45kbit/s, and can
automatically detect and adapt to the transmission rate in the network without manual setting.
• Status indication: By indicating the activity of bus segments 1 and 2, users can easily understand the real-time operation
status of the network; When the terminal resistor is not inserted correctly, segment separation operation can be performed, and
the 24V DC power display is also convenient for users to monitor the power status.
Debugging support: Segment 1 and segment 2 can be separated by a switch, making it easy to perform separate operations and
analysis on different network segments during debugging and troubleshooting.
