Page 207: Requirements For Using 1715 I/O Modules
The maximum duration for single-channel operation of I/O modules depends on the specific process and must be specified individually for each application. For high availability, Rockwell Automation suggests you use two 1715-AENTR adapters. If one of the modules faults, the adapters can operate in a simplex arrangement up to the duration of the mean time to repair (MTTR) when used in SIL 2 applications.
