Features:
- Integrates SINUMERIK CNC and PLC control in the 710.3B PN execution.
- Carries 2 GB DRAM with 1 GB non-volatile memory.
- Operates from 24 V DC in a 50 mm-wide IP20 housing.
This article is the NCU 710.3B PN control unit for an 840D sl machine configuration.
It processes motion and machine logic while maintaining network communication with drives and distributed automation.
Use the machine's software, license and topology records to verify a candidate spare before any field installation.
NCU sourcing is subject to machine-software, license and hardware-generation confirmation.
