Siemens 6SN1114-0NB01-0AA1 Communication Module

Siemens 6SN1114-0NB01-0AA1 is the PROFIBUS DP communication module for the SIMODRIVE 611 U motion-control system, serving as the optional interface that connects servo axes to a PROFIBUS DP network within a SIMODRIVE 611 U configuration. Identified as DP3 with PLL, it uses a PROFIBUS-ASIC DPC31 with PLL to deliver clock-synchronous motion control over PROFIBUS DP, enabling coordinated timing between the drive controller and connected motors. The module supports cyclic and acyclic data exchange at speeds up to 12 MBaud and is designed to handle data communication for up to two axes, making it suitable for two-axis drive configurations where deterministic communication is required. As an optional module in the SIMODRIVE 611 U family, the 6SN1114-0NB01-0AA1 provides the dedicated DP interface needed for PROFIBUS-based motion-control networks and integrates with Siemens configuration workflows described in SIMODRIVE manuals. The MLFB order number for this unit is 6SN1114-0NB01-0AA1, and it is employed in industrial automation environments that rely on Siemens drive hardware, allowing reliable transfer of position, speed, and status information between the central controller and servo drives over PROFIBUS DP.
