Siemens 6SE7090-0XX84-0FF0 Simolink Communication Card USNP

Siemens 6SE7090-0XX84-0FF0 SIMOLINK COMMUNICATION CARD USNP is a CBP (Communication Board) for SIMOVERT MASTERDRIVES motion-control systems. This SIMOLINK communications module provides a PROFIBUS DP interface via a single RS-485 port and uses a 9-pin SUB-D connector to connect to the PROFIBUS DP network on the SIMOLINK ring. As a dedicated CBP module, it enables Siemens SIMOVERT MasterDrives to exchange control and status data with PLCs and other PROFIBUS DP devices in legacy automation setups. The card carries the order number 6SE7090-0XX84-0FF0 and appears in Siemens’ SIMOLINK line as the USNP variant, designed specifically for integration with SIMOVERT MD systems. Typical applications include industrial automation lines where existing PROFIBUS DP infrastructure links SIMOVERT MasterDrives with PLCs and other DP-enabled devices to coordinate motion control tasks. Key specifications: PROFIBUS DP protocol support via the CBP interface, RS-485 electrical interface, and a 9-pin SUB-D connector for network connections. This module is part of the older SIMOVERT MD family and serves to establish a dedicated PROFIBUS DP communication path between drive controllers and the broader automation network.
