Features:
- Manages data transfer between the TDC 3000 processor and Winchester disk drives (210 MB to 1.8 GB); essential for process history storage.
- Allows setting the SCSI bus address for proper device communication; TS2 revision jumpers are factory set and not user‑adjustable.
- Uses two EPROMs (0928-101, 0928-102) at coordinates 18F/18G; field upgradeable but requires ESD precautions.
The 51401052-100 is a Smart Peripheral Controller (SPC) circuit board that serves as the SCSI bus controller for Honeywell TDC 3000 History Modules. In a DCS, the History Module is responsible for storing long‑term process data: trends, alarm and event logs, operator actions, and reports. Without a functioning History Module, a plant cannot perform regulatory compliance reporting, analyze past performance, or troubleshoot historical process upsets. The 51401052-100 sits between the system processor (EMPU, HMPU, or HPK2) and the Winchester disk drive (capacities from 210 MB up to 1.8 GB).
The 51401052-100 uses jumper pins at location TS1 to set the SCSI bus address for the History Module’s disk drive. Proper SCSI addressing is critical because multiple SCSI devices (e.g., dual drives, tape drives) may share the same bus. Incorrect address settings will cause communication failures, preventing the processor from accessing the disk. The documentation provides specific jumper configurations (Figures 9-5 and 9-11) that must be followed exactly.
The 51401052-100 requires firmware revision “G” or later to properly interface with the supported WREN III disk drives (210 MB, 445 MB, 875 MB, and 1.8 GB). The firmware is stored on two EPROM chips located at coordinates 18F and 18G on the circuit board. The original part numbers for these EPROMs are 0928-101 and 0928-102. If a board has an older firmware revision, it may not recognize larger capacity drives or may have performance issues. To upgrade the firmware, an engineer must remove the existing EPROMs using an EPROM puller while wearing a properly grounded ESD wriststrap.
The 51401052-100 Honeywell Smart Peripheral Controller may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL)by the manufacturer (OEM).

- Data Storage and Management: Manages the Wren III hard drive in the Honeywell TDC 3000 system, ensuring efficient storage and retrieval of historical data, system configurations, and operational logs.
- Industry Applications: Widely used in industries with extremely high requirements for process data recording, including oil and gas, chemical, power, and marine automation.
- Status Indicators (LEDs): Onboard LEDs display the controller's operating status and SCSI bus communication status, helping technicians quickly determine if a link is interrupted.
- Firmware Compatibility Diagnosis: The system checks the SPC's firmware version. For example, in LCN Release 500 or later, if using an 875MB/1.8GB drive, the firmware must be Rev G or higher; if the firmware version does not match, the system will report an error or experience performance degradation.
- Physical Protection: This card is typically installed in a protective enclosure and connected via a dedicated SPC I/O Paddle Board to protect the core circuitry from external signal interference.
- Installation Method: Panel-mounted, requiring a compatible I/O paddle board (such as the SPC II I/O Paddle Board used for WDA legacy modules).
- Dual Logical Drive Upgrade: If you plan to replace storage with newer dual logical drives, the SPC firmware must be upgraded to Rev J or higher (Rev H is usable but will impact performance).
- Hardware Version: Common hardware revisions on the market include Rev C, Rev F, and the latest Rev L. When upgrading, prioritize higher revisions for better stability.
