The performance variants for the 6FC5357-0BB25-0AA0 are as follows. This unit uses a Celeron 650 MHz processor and includes 6 MB of CNC user memory.   PLC: PLC 317-2DP, PLC memory: 128 / 768 KB. It has a type 3 front panel with no fan box.

Features of the Siemens 6FC5357-0BB25-0AA0

The NCU module 6FC5357-0BB25-0AA0 is the CPU of the SINUMERIK 840 D. It is in control of the communication tasks for the CNC and PLC. There are a few features that are standard for the 5xx.5 series NCU modules.  Some of these standard features include a standard PCMCIA card, four high-speed NC inputs as well as four rapid NC outputs.  Also, the standard on the 6FC5357-0BB25-0AA0is two measuring pulse inputs, two handwheel inputs, and monitoring of both the voltage and the temperature.

Components associated with the NCU module 6FC5357-0BB25-0AA0

Several modules make up the components working with the 6FC5357-0BB25-0AA0module. The first one of these components that the Siemens NCU module 6FC5357-0BB25-0AA0 is a part of is the NCU box which is the module rack for the 6FC5357-0BB25-0AA0 and has three parts. The NCU box has an NC rack assembly with a cable distributor, a battery/fan unit that slides into the box, and a housing unit made of sheet metal. The housing unit is integrated with guide bars that allow for the NCU, the fan and battery part, and the power supply module to fit inside neatly.

The next coordinating component for the Siemens 6FC5357-0BB25-0AA0 is the fan box. This unit is only absolutely required for the 573.3 (Pentium III) and 573.4 (Pentium III) NCUs and can be mounted to the NCU box if need be.

Another coordinating component for the Siemens 6FC5357-0BB25-0AA0 is the PLC module as a submodule of the NCU. 

This module assists in machine monitoring. It also serves as a PLC-CPU compatible with the S7-300 group of units.

COM modules are a submodule of the NCU and are an associated component as well. The task of the COM module is to communicate with the PCU and the peripherals of the PCU.

The driver module is another component associated with the Siemens 6FC5357-0BB25-0AA0 NCU module. Also, a submodule of the NCU, the driver module forms the interface to several units.It is the interface for the operator's front panel, the programming device, the decentralized peripherals, and the S7-300 peripherals.

The final coordinating component of the Siemens 6FC5357-0BB25-0AA0 NCU module is the PCMCIA card. The PCMCIA card has a couple of functions. It serves as the bulk memory for the NC system software, and it can be used for the start-up.  To operate the PCMCIA cards, the NCU has a plug-in unit that allows standard PCMCIA as well as PC cards or NC cards to be inserted. Type II flash cards up to 8 MB storage capacity can be operated through the plug-in.
