Feature: QuickFail Logic

QuickFail Logic is inherent to Intellution's version 7.x I/O drivers. Drivers with

QuickFail do exactly that – quickly determine if there is a communication problem

with a device and, if detected, bypass all datablocks on the device. The driver

intermittently attempts to read or write to the device but does not linger on the device

if it still has a communication failure. The QuickFail feature significantly increases

the efficiency of your process, especially if you have many datablocks configured on

one device.
