Abstract
A device includes multiple communication interfaces configured to send and receive data over multiple communication paths. The device also includes multiple input/output (I/O) channels configured to communicate with multiple field devices. The device further includes at least one processing device configured to process at least some of the data and control at least one of the field devices based on the processed data. The device may also include an intrinsic safety barrier electrically separating the communication interfaces and the I/O channels. The communication interfaces may include at least one first interface configured to communicate over one or more first communication paths with at least one component of an industrial control system and at least one second interface configured to communicate over one or more second communication paths with at least one other device that is configured to communicate with additional field devices.
