Honeywell 900S75-0460 Scanner Modules
1.The I/O Scanner 2 module resides in a remote I/O rack along with its I/O in a Redundant Controller System.
2.The Scanner 2 has two I/O connections I/O A is connected to CPU-A and I/O B is connected to CPU-B in the Redundant Controller rack.
3.The scanner 2 collects data from the Input modules populated in its remote rack and communicates the information to the Lead controller.
4.Output data is sent from the Lead controller to the Scanner 2 module which in turn sends the data to appropriate output module.
5.Data exchanges are synchronous with the controller scan time to maintain deterministic operation.
6.Diagnostic status of I/O modules is also monitored and reported to the controller when detected.
