Product Description

What this part is

A Siemens plug-in printed circuit board marked with board reference 570 363 9102.02. The 570-xxx-9xxx.xx scheme is Siemens’ internal board reference for the SINUMERIK CNC generation that includes the SINUMERIK 810 and 820 and their 8-series relatives — boards from that era carry a 570 reference on the PCB itself and a 6FX1 order number on the accompanying label. This is a card-rack board out of a CNC control unit.

Correcting the source data

Earlier copy described this as a circuit board for use in various electrical equipment and supplies, suitable for prototyping. That is not what it is or who it is for. It is a specific plug-in board from a specific Siemens CNC platform. It has no general-purpose use, is not a prototyping or development board, and does nothing outside a SINUMERIK control unit of the matching generation.

Reading the board reference

570 — Siemens board-reference series for this CNC generation. Sibling boards in the same racks carry references such as 570 205 9102.03, 570 300 9102, 570 374 9001.52, 570 375 9101.00 and 570 471 9102.00, which is how you can recognise a board as belonging to this family at a glance.363 — the board drawing number, which is what fixes the function9102 — the build variant within that drawing.02 — the version. Version digits matter on Siemens CNC boards: a .02 and a .03 of the same drawing are not automatically interchangeable, and the control’s software release can be the deciding factor.

How to order this correctly

The 570 reference identifies the board, but the number Siemens and its distributors trade on is the 6FX1 order number that accompanies it — SINUMERIK boards of this era are habitually catalogued as, for example, 6FX1130-0BB01 with board reference 570 300 9102, or 6FX1137-5BA01 with 570 375 9101.00. Take both numbers off the board you are replacing, quote both, and match both. That is the single most reliable way to avoid a wrong-board order on a SINUMERIK 8-series rack, where several boards share a physical footprint and a connector layout while doing entirely different jobs.

Installation and setup notes

Power the control fully down and allow it to discharge before opening the rack; SINUMERIK cabinets of this generation hold charge and the boards are static-sensitive. Before removing anything, photograph the rack, note the slot the outgoing board occupies, and write down both the 570 board reference with its version digits and the 6FX1 order number from the label. Check the outgoing board for jumper blocks, DIP switches and any fitted EPROMs or memory devices — on SINUMERIK boards of this era, configuration and machine-specific software frequently live in sockets on the board itself, and a replacement board without them will not bring the machine up. Back up machine data before you start. Bring the control up with drives disabled and clear alarms in order rather than assuming the first one is the cause.

Quantity and configuration

One printed circuit board. Not included: the CNC rack, card cage, backplane, ribbon and interface cables, connector kits, EPROMs or memory devices, backup battery, other boards from the rack, and the machine documentation.

Interchange guidance

Match the drawing number, the variant and the version digits, and cross-check the 6FX1 order number. Other 570-series boards from the same racks are different functions and are not substitutes despite sharing the family prefix and the physical form factor. Boards from the later SINUMERIK generations do not retrofit into an 8-series rack at all. Also written 570-363-9102.02, 570363910202, 570 363 9102 02, 570363.9102.02 and 570.363.9102.02.
