摘要:
Safety level error detection comparable to that provided by redundant wired safety relays is obtained on a backplane of a programmable logic controller or the like by a combination of error detection methods that in sum provide the requisite level of error detection required without necessitating a particular hardware requirement or duplicative message transmissions.
