Siemens APACS ModulNET Interface PC Card (P/N 16413-15, old PN 16267-1)

Overview

The Siemens APACS ModulNET interface PC card, part number 16413-15 (previous part number 16267-1), is a communication module for the APACS and APACS+ distributed control system. Moore Products Co. developed the system, and Siemens continued it after acquiring Moore. The card is installed in a PC-based station and connects that station to the ModulNET network, which carries data between the APACS process controllers and the operator and engineering stations.

APACS+ is a legacy platform and is no longer offered as a current Siemens product line. This card is therefore mainly bought as a like-for-like spare for plants that still run APACS+ systems, often while a migration to a current DCS is being planned. Electrical and environmental data for this card could not be confirmed against a current official Siemens datasheet, so this page lists only the identification data.

Key Features

• PC interface card for the APACS/APACS+ ModulNET network
• Part number 16413-15, which supersedes the earlier part number 16267-1
• Connects operator and engineering stations to the APACS process controllers
• Legacy Moore Products / Siemens hardware for the existing installed base
• Used as a critical spare in obsolescence management of APACS+ systems

Technical Specifications

Applications

• Like-for-like replacement of ModulNET interface cards in APACS+ operator and engineering stations
• Critical spares holding for legacy DCS installations in petrochemical, chemical and power generation plants
• Keeping legacy APACS+ systems running in the GCC until a planned migration to a current control system

Before replacing a card, check the part number and revision label of the installed card and the station software version against the APACS system documentation.

Why Seven Star LLC

Seven Star LLC sources legacy Siemens and Moore APACS+ spares for plants across Oman and the GCC. Before quoting, we check the part number history (16267-1 to 16413-15) and the revision of the card against your station documentation, so that the replacement matches the installed system.

How the Siemens APACS ModulNET Interface PC Card Works

In an APACS or APACS+ distributed control system, the process controllers execute the control strategies, while operator and engineering workstations are used to monitor the plant, change setpoints, acknowledge alarms and download configurations. ModulNET is the plant-level network that links these devices. The Siemens APACS ModulNET interface PC card is the hardware that gives a PC-based station its physical and logical connection to this network. Without a working card, the station cannot exchange data with the controllers, so operators lose visibility of that part of the process and engineers cannot reach the controllers from that node.

The card sits inside the station computer and is driven by the APACS station software. Data requested by the human-machine interface, such as tag values, alarms and trend data, is passed from the controllers across ModulNET and through the card to the application running on the PC. Because the card and the station software work as a pair, the card revision and software version must be compatible.

Part Number History

Part number 16413-15 supersedes the older part number 16267-1. When a plant spares list still shows 16267-1, the 16413-15 card is the replacement to check against the station documentation. Always confirm the revision label on the installed card before ordering.

Selection & Ordering Guide

• Read the part number and revision label directly from the installed card, not only from the spares register, which may be out of date.
• Record the station type, the host PC and the APACS station software version, since these decide which card revision is compatible.
• Check the number of stations that use this card across the site, so spares holding can be planned for the whole installed base.
• Our team can help confirm the correct ordering code for your Siemens APACS ModulNET interface PC card before you place a purchase order.

Installation & Maintenance

Replacing an interface card in a running DCS needs planning. Follow the plant permit-to-work procedure and the APACS system documentation. General good practice includes:

• Confirm that the affected station can be taken out of service and that other operator stations keep view of the process during the change.
• Shut down the station PC correctly and isolate power before opening the chassis.
• Use antistatic precautions (wrist strap, grounded mat) when handling the card, because electronic boards are sensitive to electrostatic discharge.
• Seat the card firmly, secure it, and reconnect the network cabling exactly as it was.
• After start-up, check that the station communicates with all controllers and that no network diagnostics or alarms are active.
• Keep the removed card labelled for repair evaluation and update the spares register.

Lifecycle and Migration Planning

Because APACS+ is a legacy platform, spare cards become harder to find each year. Many plants keep a small stock of critical communication spares while they prepare a migration to a current control system. A practical approach is to list every ModulNET node, identify single points of failure, and hold at least one tested spare for the most critical stations. Spares should be stored in antistatic packaging in a dry, temperature-controlled store.

Typical Applications in Oman & the GCC

APACS and APACS+ systems were installed in oil and gas, petrochemical, chemical and utility plants. In Oman and the wider GCC, the Siemens APACS ModulNET interface PC card is typically requested by maintenance teams that need to keep an existing control room running safely until a planned upgrade is complete.
