The Siemens 6FC53570BB330AE1 is manufactured for use worldwide. Field applications include:
Laser machining

The SINUMERIK 840D sl can also be used in wood and glass processing and handling operations as well as transfer lines and rotary indexing machines. Easy integration with mass production and JobShop production.

High-Speed cutting applications

Used for the production sector, the Siemens 6FC53570BB330AE1 can be used with ShopMill, Shop Turn, and Motion Control Information System Products operating and programming software.
The following components can be attached to the Control Unit:  SINUMERIK operator panel front with TCU/PCU 50.3 and Machine Control Panel/Machine Push Button Panel, SIMATIC CE panel, SINUMERIK handheld units, Distributed PLC I/O via PROFIBUS DP or PROFINET I/O (only applies to NCU 720.2 PN and NCU 730.2 PN), SINUMERIK PP 72/48 peripheral module, SINUMERIK ADI 4 analog drive interface for four axes, SINAMICS 120 drive system, Feed, and main spindle motors – 1FT/1FK/1FN/1FW6/1FE1/2SP1 synchronous motors – 1PH/1PM asynchronous motors With the NCU 720.2 PN and NCU 730.2 PN, the SINUMERIK 840D sl offers integrated PROFINET functionality.
Supported by the following: PROFINET CBA functionality, The CBA functionality within the NCU allows you to modularize machinery and systems: Quick real-time communication (up to 10 ms) between the controllers means that systems help standardization and may be reused or expanded more easily. Response time is faster and more flexible and startup is simplified and sped up by pretesting. PROFINET IO It is a part of PROFINET. PROFINET IO is a communication tool that is used to put into action modular, distributed applications. PROFINET IO is based on Industrial Ethernet and allows distributed field and I/O equipment to be connected to the central processing unit. 256 PROFINET IO devices can be operated on the NCU as an IO controller.
For applications, the Siemens module has some prerequisites including user interfaces (UI)  as well as interfaces for servicing, start-up, and maintenance.
To ensure that the module Siemens 840D sl 6FC53570BB330AE comply with the safety requirements, there are several components integrated into the system. These components include Numerical Control Unit (NCU), Machine Control Panel MCP, Machine Push Button Panel MPP, Keyboard, Operator panels (operator panel front + TCU/PCU), Distributor box, and the handheld unit, S7-300 I/O with IM 153 interface module.
The Siemens SINUMERIK 840D sl comes with a two-year warranty.
