Frequently Asked Questions (FAQ)

Q1: What is the Siemens 6ES7972-0AA01-0XA0?

It is a SIMATIC DP RS485 repeater for connecting and extending PROFIBUS DP and MPI bus segments. It supports up to 31 nodes at speeds up to 12 Mbit/s .

Q2: Is this product still in production?

No. Siemens discontinued this product effective 01/10/2012 (PM500 status). The direct successor is the 6ES7972-0AA02-0XA0 .

Q3: Can I use this repeater with the successor model in the same network?

Yes. The 6ES7972-0AA02-0XA0 is the designated successor and is functionally compatible. Mixing the two models in a network is generally acceptable as long as baud rates and segment rules are observed. However, for new installations, the successor is recommended.

Q4: How many nodes can one repeater support?

Up to 31 nodes per repeater .

Q5: What is the maximum transmission speed?

12 Mbit/s, with automatic detection from 9.6 kbit/s to 12 Mbit/s .

Q6: Does it provide electrical isolation?

Yes. The repeater provides galvanic isolation between the two bus segments .

Q7: What is the power supply requirement?

DC 24 V (20.4–28.8 V), with a maximum input current of 200 mA (no load) or 300 mA (with PG/OP load) .

Q8: What are the dimensions and weight?

45 × 128 × 67 mm (W × H × D), approximately 350 g .

Q9: What should I verify before ordering?

Always verify the exact part number, confirm your application can use a discontinued product (or consider the successor 6ES7972-0AA02-0XA0), and ensure your PROFIBUS network operates within the repeater's baud rate and node limits.
