Siemens 6FC5357-0BB35-0AB0 SINUMERIK 840D NCU 573.5B CNC and PLC Control Unit
Product Description
6FC5357-0BB35-0AB0 is a SINUMERIK 840D NCU 573.5B with integrated CNC and PLC resources. Its 1.4 GHz hardware, 3 MB NC memory and 128 KB PLC memory distinguish it from neighboring NCU 573 variants.
The 573.5B variant must be matched by its complete suffix and documented machine baseline. During replacement, keep the NC and PLC archives linked to the drive-bus arrangement and verify cooling, storage and communication interfaces before commissioning motion.
Technical Specifications
Exact 573.5B Identity
Suffix control
0AB0 identifies this hardware state; do not reduce the order check to 'NCU 573.5'.
Memory fit
NC and PLC archive size must fit the target configuration.
Lifecycle planning
Keep a tested spare and restorable archive because the product is in a legacy spare-parts phase.
Spare Readiness Test
Bench-check
Bench-check the spare, fan/battery condition and firmware identity.
Verify
Verify the series startup archive can be read by the retained engineering tools.
Document
Document a controlled swap and machine acceptance procedure before a failure occurs.
FAQ
Which order-code checks belong to the Exact 573.5B Identity decision for 6FC5357-0BB35-0AB0?
Match the complete order code, hardware revision, cooling and installed system configuration; a similar family name is not enough for replacement selection.
What must be backed up before the Spare Readiness Test procedure for 6FC5357-0BB35-0AB0?
Save the editable application, hardware configuration, communication parameters, retained production data and the firmware or software baseline used by this SINUMERIK 840D NCU 573.5B CNC and PLC Control Unit.
How does suffix control affect Exact 573.5B Identity for 6FC5357-0BB35-0AB0?
0AB0 identifies this hardware state; do not reduce the order check to 'NCU 573.5'.
Why does memory fit need separate verification during Spare Readiness Test for 6FC5357-0BB35-0AB0?
NC and PLC archive size must fit the target configuration.
How should 6FC5357-0BB35-0AB0 complete the Spare Readiness Test sequence before return to service?
Complete the documented startup sequence, verify diagnostics and communications, test the application under controlled conditions and confirm the applicable machine interlocks.
Which records confirm that 6FC5357-0BB35-0AB0 completed the Exact 573.5B Identity review?
Keep the restored configuration, test results, diagnostic status and the final record for lifecycle planning so the installed baseline can be reproduced during later maintenance.
Moore Automation supplies programmable controllers, remote I/O, operator panels and industrial PCs used across factory and process applications.
Coverage includes GE, Siemens, Schneider Electric and other PLC and HMI families, from current platforms to older installed systems.
