The AOUTR channels and four redundant 0 to 20 mA dc analog block handles output writes and initialization logic for output channels. The inputs/outputs are galvanically the redundant channels. On each execution cycle of isolated from other channels and ground. the AOUTR block, identical output writes are sent to both modules, fully exercising the fieldbus and the A redundant pair of the modules combine to provide logic circuitry of each module. When a failure is redundancy at the Fieldbus Module (FBM) level, with detected in one of the modules, its output is driven to field I/O wired to one common termination assembly 0 mA and the corresponding channel in the good (see Figure 1). Each module independently attempts module automatically continues supplying the proper to hold the output(s) at its specified output value(s), current to the output current loop. and each independently reports its observed value of the inputs. A redundant analog input function block, AINR, is used for each redundant pair of inputs.
