The Tiway card driver is partly serviced by interrupt and partly by an idle task. Because of this, if Windows or Citect is busy, the idle task may take a while to run, and cause slower performance (and possibly timeout) on the Tiway Driver.

The Tiway driver has been modified to be totally processed by the interrupt service routine. This will give higher performance and will prevent any timeout errors.

These modifications have been introduced after version 2.01 and will be released with version 3.0. If you require this modification before version 3.0 contact Citect support.
