A method includes transmitting a first value to a first slave device via a communication bus, where the first value is within a first range of values associated with the first slave device. The method also includes receiving a second value via the communication bus and detecting a fault when the second value is not within the first range of values associated with the first slave device. Detecting the fault could include detecting a decoder fault when the second value is within a second range of values associated with a second slave device. The method may further include detecting a fault when the second value is within the first range of values associated with the first slave device but does not equal the first value or detecting no fault when the second value equals the first value.

Apparatus and method for fault detection to ensure device independence on a bus

System () and method () for enabling peer-to-peer communications between controllers () of at least two control systems (). The system () include a first control system (FCS) having a first controller (FC) communicatively coupled to a first input/output (I/O) processing module () via a first I/O network (). The first I/O processing module is communicatively coupled to first automation equipment (). The second control system (SCS) includes a second controller (SC) communicatively coupled to the FC via the first I/O network. The first I/O network provides peer-to-peer communications between the FC and SC. The SC is configured to emulate the first I/O processing module. More particularly, the SC is configured to match an internal I/O configuration with an I/O configuration of the FC.

Systems and methods for peer-to-peer control using an input/output network

A system that employs a chosen one of a plurality of presentation selections to present information from a field device. The system has a field device interface that configures the field device in accordance with the chosen presentation selection. A control configurator programs the field device interface in accordance with the chosen presentation selection.
