Safety controller with safety response time monitoring |
摘要 |
A safety controller having a total worst case propagation delay, exceeding the required propagation delay required by a safety process, may be used to control the safety process by monitoring actual delays in signal processing in the safety controller and moving to a safety state if a signal delay exceeds an amount less than the total worst case propagation delay.
