Abstract (en)
[origin: WO2016010521A1] An apparatus includes at least one first input/output (I/O) module (204) having multiple first I/O channels (224, 228). Each first I/O channel (224, 228) is configured to provide a communication path. The apparatus also includes a second I/O module (212) having multiple second I/O channels (244, 248). Each second I/O channel (244) is configured to provide a redundant communication path for one of the first I/O channels (224). The apparatus is configured to provide the redundant communication paths for only a subset of the first I/O channels (224, 228). The first I/O channels (224, 228) may include critical I/O channels (224) and non-critical I/O channels (228), and the apparatus may be configured to provide the redundant communication paths for only the critical I/O channels (224).
