Swift 5000 is identical to T3 except in the ge300 drives interface. GVI (Swift) VS. DDI (T3).
From there on the Futura and TK product lines cross as far as labelling of I/O's, software, but not necesarrily on hardware.
The later versions of Swift (Futura, Meridia) have the best troubleshooting software I've ever seen. An event trapper that lets you set a fault as the event to trigger off of, and then when the event happens captures the last 45 seconds of I/O at 10 frames per second, on the I/O screen and allows you to replay I/O, 1/10th second at a time. Very cool.
And with Swift Remember..They bill themselves as Non-Proprietary. All manuals, wiring diagrams are available on their website.
