Of course, never hesitate to call myself or any of your Rumsey Automation Specialists to discuss your specific application in more detail.


Description optional. Users can automatically perform proof tests 1756-l7x usb switching ground open on input modules and checking to make sure all input points go to zero turn OFF.

Calibrate analog input and output modules 1756-l7x usb verify that accurate data is obtained from and used on the modules. Proof Testing with Redundancy Systems A ControlLogix redundancy system uses an identical pair of ControlLogix chassis to keep your process running if a problem occurs with one of those chassis. When a failure occurs in the primary chassis, control switches to the secondary controller.

The switchover can be monitored so that the system notifies the user when it has occurred. In this case that is, when a switchover takes placewe recommend that you replace the failed controller 1756-l7x usb the mean time to restoration MTTR for your application.

If you are using controller redundancy in a SIL 2 application, you must perform half the proof 1756-l7x usb on the primary controller and 1756-l7x usb the proof test on the secondary controller. TIP If you are concerned about the availability of the secondary controller if the primary controller fails, it is good engineering practice to implement a switchover periodically for example, once per proof test interval. For more information on the available instructions and for a full description of logic operation and execution, see the following publications: Logix Controllers General Instruction Set Reference Manual, publication RM ControlLogix System User Manual, publication UM Reaction Times in Redundancy Systems The worst-case reaction time of a duplex system is different than a simplex system.


1756-l7x usb redundancy system has a longer reaction time because of the following: There are a series of cross-loading operations that continuously occur between the primary and secondary controllers. What is New Surplus?
