Functional Description

The VMIVME-3122 is a high-resolution, 16-bit, 64-channel analog scan and digitizing input board for VMEbus system applications.

Dual-port data memory, on-board timers, automatic gain control, and programmable bus interrupters enable the VMIVME-3122 to support large amounts of analog input traffic with minimal host processor involvement.

Analog inputs are scanned and digitized sequentially. Digital values are stored in dual-port data buffers that are readily accessible from the VME bus.

The gain of each channel can be programmed individually or set by software to a fixed gain common to all channels. Channel gains are software selectable to x1 or x10.

The A/D converter voltage ranges are jumper-selectable to ±2.5 V, ±5 V, ±10 V, 0 to 5 V, and 0 to 10 V. The A/D converter voltage ranges can be set to ±1 or x10 by software.

Upon system or program reset, the board will initialize in 64-channel auto-scan mode at 100 KHz with all channel gains initialized to 1 (x1).

After the reset operation, the program can dcs-sis.com select timed burst or triggered burst mode and modify the block size, buffer size, and channel gains as desired.

The channel block can be adjusted to 1. 8. 16. 32. or 64 channels, and the data buffer size can be selected from 16 to 1.000 channels.

The data buffer size is selectable from 16 to 1.024 data words in binary increments.

In standard performance mode, the board must be reprogrammed after a reset to obtain a 50 kHz scan rate. The value of $00F7 must be written to relative address $0006.

Timed Data Bursts are controlled by an interval timer that provides repeat or single burst intervals of up to 687 seconds.

A burst can contain from 8 to 1.024 channel samples. A data ready flag can be used in the middle or at the end of a scan, and an interrupt request can be generated at the same time as the flag.

An interrupt can also be initiated after a specific number of samples have been acquired.

Features

Description: The VMIPCI-5565 is the PCI member of the dcs-sis.com VMIxxx-5565 family of reflective memory (RFM) real-time networking products from GE Fanuc Embedded Systems.

Other members of this family include the VME-compatible board VMIVME-5565 and the PCI mezzanine card (PMC) VMIPMC-5565.

All three products are network compatible and can be integrated into a network in any combination.

This family of products allows computers, workstations, programmable logic controllers (PLCs) and other embedded controllers with different operating systems or no operating system at all to share data in real time.

Reflective Memory boards are like shared memory for local nodes.

Any level of software, including the application program itself, can write to or read from the memory.

Data written to one node’s Reflective Memory is transferred by the network hardware to all other nodes and placed in the same addresses on those nodes’ Reflective Memory boards.

This data transfer does not require the involvement of a processor on any node. With this system, all nodes on the network have a local copy of the shared data that is immediately accessible.
