16413-1-1 / 16413-1-5 – Siemens APACS MBI/NMI PCI Card

Name: Siemens APACS MBI/NMI PCI Card | Seven Star LLC
Brand: Siemens

Description

Overview

The Siemens APACS MBI/NMI PCI Card (part numbers 16413-1-1 and 16413-1-5) is a legacy PCI interface card used to connect APACS+ and QUADLOG control systems to host computers. Designed by Moore/Siemens, the board enables communication through the Module Bus Interface (MBI) and Network Module Interface (NMI), giving engineering and monitoring workstations a reliable link into an APACS+/QUADLOG system.

Seven Star LLC supplies genuine and tested Siemens APACS spare parts, including the 16413-1-1/16413-1-5 PCI card, to plants running legacy APACS+/QUADLOG systems across Oman and the GCC, helping maintain critical installed control infrastructure.

Operating Principle

The card installs as a standard PCI board in a host computer and provides two distinct communication paths: the Module Bus Interface for direct communication with APACS+ controller modules, and the Network Module Interface for network-level data exchange with the wider control system. Together, these let an engineering workstation both configure individual controller modules and monitor overall system status from a single PC.

Because the card handles this communication at the hardware level rather than through a generic network adapter, it preserves the deterministic, low-latency link that APACS+/QUADLOG engineering tools expect, which is important for configuration and diagnostic work on safety-related QUADLOG systems.

Engineering Design of the 16413-1-1/16413-1-5

The card is built to the standard PCI form factor for straightforward integration into a Windows-based engineering or monitoring workstation, without requiring specialized computer hardware beyond an available PCI slot. As the underlying APACS+/QUADLOG platform has been discontinued by Siemens, these cards are supplied as tested, functional legacy hardware, keeping installed control systems operable without forcing a premature full-system upgrade.

Because supply of this exact card has become limited as the platform ages, sourcing a properly tested unit matters more than with current-production hardware — a card that tests as functional at time of shipment is the practical assurance available for legacy APACS+/QUADLOG spares of this type.

Industrial Applications

The 16413-1-1/16413-1-5 card is used in engineering workstations for Siemens APACS+ distributed control systems and QUADLOG safety systems, as well as in control room PCs that require MBI/NMI communication for ongoing system maintenance, diagnostics, and expansion work in legacy plants. It remains a necessary component wherever an installed APACS+/QUADLOG system is still in active service.

Across Oman, Muscat, Sohar, Salalah, and the GCC, Seven Star LLC supports plants running legacy Siemens APACS+/QUADLOG systems as a supplier of tested spare parts including this PCI interface card, helping extend the operational life of installed control and safety systems.
