TEWS TVME200-10 | 6U VMEbus Carrier for Four IndustryPack Modules

Description

Key Technical Specifications

The TEWS datasheet specifies the four-slot architecture, VMEbus addressing modes, IRQ1–7 support, 8 MHz interface, absence of DMA, 50-pin ribbon-cable I/O, and -40°C to +85°C operating range.

Product Introduction

TEWS TVME200-10

The TEWS TVME200-10 is a 6U VMEbus carrier board for IndustryPack modules, providing the bridge between up to four single-size IP modules—or two double-size modules—and a VMEbus backplane. It supports A16, A24, and A32 addressing and routes IP interrupts to VMEbus IRQ1–7.

This board is useful when maintaining legacy VME-based industrial or embedded systems where replacing the complete VME architecture is impractical. The carrier itself does not provide application-specific I/O; the installed IndustryPack modules determine the actual analog, digital, communication, or other I/O functions.

Application Scenarios & Field Pitfalls

Engineering Pain Point

Legacy VME systems rarely fail in a convenient way. A single carrier problem can appear as several missing I/O functions because multiple IndustryPack modules share the same VMEbus carrier. Before replacing four IP modules independently, check the TVME200-10, its VMEbus connection, IP power rails, interrupt configuration, and individual slot status.

Typical Applications

• Industrial Process Control — Hosting IndustryPack analog and digital I/O modules in legacy VME control systems.
• Factory Automation — Modular machine-control I/O where VMEbus remains the system backplane.
• Telecommunications Equipment — IndustryPack-based interface expansion in embedded VME platforms.
• Test and Measurement — Multi-function acquisition and control systems using several IP modules in one 6U VME carrier.

Technical Pitfalls to Avoid

1. Do not mistake the carrier for an I/O module.
   The -10 provides the VMEbus/IP infrastructure. The actual I/O function comes from the installed IndustryPack modules.
2. Check IP slot loading.
   The board accommodates four single-size IP modules or two double-size modules. Do not install a mechanical combination that exceeds the carrier’s supported arrangement.
3. Verify the IP power rails.
   The carrier distributes +5 V, +12 V, and -12 V to the IP modules. TEWS specifies self-healing fuses and RF filtering on the IP power lines. A power fault can therefore affect an individual IP slot without necessarily indicating a VMEbus failure.
4. Do not assume DMA capability.
   The -10 uses an 8 MHz VMEbus interface and does not provide DMA. Applications expecting DMA-based high-throughput transfers need an architecture review.
5. Check interrupt mapping.
   IP interrupt levels are routed to VMEbus IRQ1–7 and can be configured by software or through predefined rotary-switch settings. Incorrect interrupt configuration can produce symptoms that look like software or IP-module faults.
6. Record rotary-switch settings before replacement.
   The carrier uses sixteen-position rotary switches for address and interrupt configuration. Photograph the original settings before removing a failed board.
7. Do not confuse -10 with -20.
   The provides front-panel I/O, while the -20 adds rear I/O capability for specified IP modules. The distinction matters when the existing cabinet uses rear-panel signal access.
8. Check the RoHS suffix.
   is the RoHS-compliant successor/configuration, while is the non-RoHS version. Do not assume that the suffix is cosmetic when procurement or site compliance requirements are involved.
9. Inspect the VME P2 connector carefully.
   uses P2 for VMEbus signals and power connections. TEWS documentation specifically identifies the P2 pin assignment for this version.
10. Verify the actual IndustryPack module.
    A carrier replacement does not guarantee system recovery if the installed IP module has a different memory map, interrupt requirement, or I/O connector arrangement.
