Introduction

The ibaLink-SM-128V-i-2o VMEbus Interface Card is a multi-purpose, bi-directional interface card designed for use in VMEbus-compatible PLCs and computer systems.

It can be used for both data acquisition and process monitoring as well as for control system applications such as the ibaLogic SoftPLC.

In the following, the board will be named SM128V to simplify the description.

Key features of the SM128V include :

 1 bi-directional fiber optic link with 64A+64D inputs/outputs per link (channel 1)

 1 unidirectional fiber optic link with 64A+64D outputs per link (channel 2)

 Synchronized transmission of all channels on both links at a rate of 1ms

 Address switch for cascading up to 8 SM128V interface cards on a link

Channel 1

 Compatible interface for ibaFOB-io, ibaFOB -4i (-S), ibaFOB-4o

 Compatible process i/o interface for ibaPADU-8-IO series and ibaNet750-BM series

 5 V power supply from VMEbus
