SINNESLÖSCHEN SYSTEM BUS (SSB)

Sinneslöschen System Bus

The Sinneslöschen System Bus (SSB) is a modular system interconnect developed for Sinneslöschen industrial control, instrumentation, display and data-acquisition equipment. Introduced in 1985, SSB provides a common electrical and mechanical interface for processor, interface, acquisition and specialized-function modules installed in Sinneslöschen system chassis.

Three principal generations remain represented in supported installations: SSB-1, SSB-2, SSB-2E. Current system development increasingly uses PCI-based host hardware, but SSB remains supported for established industrial, laboratory and OEM installations.

Applications

Industrial control systems; laboratory instrumentation; automated test equipment; data-acquisition systems; visualization systems; OEM equipment; development and service platforms.

SSB-1

Introduced: 1985 · Status: LEGACY SUPPORT

SSB-1 established the original modular architecture. Typical characteristics include asynchronous system transfers, centralized bus arbitration, vectored interrupt support, configurable module addressing, modular card-cage installation, and external timing and termination requirements.

SSB-1 modules should not be assumed to operate directly in later SSB chassis. Supported mixed-generation installations may require approved adapters, timing modules or termination hardware.

SSB-2

Introduced: 1989 · Status: CURRENT / LEGACY INSTALLED BASE

SSB-2 revised the original architecture with expanded addressing, improved arbitration, bus-mastering support, DMA capability for selected modules, improved diagnostics and updated module-identification conventions.

SSB-2E

Introduced: 1993 · Status: CURRENT

SSB-2E retains compatibility with approved SSB-2 modules while adding extended addressing, burst-transfer support, improved arbitration, revised timing control, enhanced module identification and expanded diagnostic reporting.

Compatibility

Not all SSB modules are interchangeable. Compatibility depends on chassis generation, module revision, module position, bus timing, termination, power requirements, interrupt configuration, address allocation and installed bridge/adapter hardware.

Many SSB-2 modules may be installed in supported SSB-2E configurations. Selected SSB-1 modules may be retained through approved adapter, timing and termination configurations, restricted slot positions and reduced transfer modes.

Do not relocate an SSB-1 module within an established mixed-generation chassis without verifying the applicable configuration documentation.

Bus Termination

Correct termination is required for reliable SSB operation. Requirements vary according to bus generation, chassis length, installed module count, module position, adapter hardware and mixed-generation configuration. Improper termination may result in intermittent transfer errors, module-identification failures, startup problems, diagnostic faults or unreliable operation under high bus activity.

Refer to AN-SSB-17 — SSB Termination Requirements before modifying an established chassis.

Timing Modules

Certain mixed-generation and specialized installations use dedicated timing hardware to maintain approved bus-transfer characteristics. Timing modules may be required when earlier modules are installed in later chassis, extended chassis configurations are used, selected high-speed modules share a bus with legacy hardware, or bridge interfaces alter normal bus-master timing.

PCI Integration — SL-9816

The SL-9816 provides an interface between PCI-based host systems and supported SSB equipment. It supports SSB-2, SSB-2E and selected SSB-1 configurations through approved adapter hardware. Functions include address translation, interrupt mapping, DMA support, diagnostic access and legacy timing accommodation.

Configuration Software

SSB Configuration Utility 2.6 — module enumeration, address verification, interrupt reporting, timing information, termination checks where supported and configuration reports.

SSB Diagnostic Toolkit 2.4 — bus scanning, module-status reporting, transfer testing, interrupt diagnostics, timing tests and configuration comparison. CONTROLLED DISTRIBUTION.
