VMEbus systems
The past 20 years the VMEbus has
reached a dominant position for
industrial busses with a number of
suppliers.
Despite numerous new bus systems
based on the rapid changes in chip
technology, VMEbus systems offer
significant advantages such as their
robustness, reliability and increased
availability of processor, memory and
I/O cards.
Additional advantages appear under
real-time conditions, where unforeseen
events have to be managed. This is
realised with the program interrupt
concept and variable control that closely
monitors the bus system.
With the increase in processing speeds and data transmission rates, 3 row DIN 41 612
connectors have reached their limit, so the VME standard needs to be enhanced further.
When VME architecture was increased from 8-bit to 64-bit and data transmission rates up to
160 Mbyte/s (VME 64x), HARTING introduced
with 160 pins. This Eurocard connector
is 100 % backwards compatible to existing 3 row connectors with 96 contacts, therefore old can
plug into new.
To offer the best design possible from the start, HARTING developed spice models that were
later certified via signal integrity measurements of the connector.
