HARDWARE APPLICATION
The FEC module interfaces analog and digital signals from field devices to the MFP or MFC module. The IMFEC11 module can interface Bailey-Fischer & Porter FSK smart transmitters and other smart devices. The IMFEC12 is for use with conventional transmitters (BC, EQ and PT) and standard analog inputs. The IMFEC11 module can operate in one of two modes: FSK field bus mode or FSK analog point-to-point mode. In the FSK field bus mode, a single two-wire input (bus) links a maximum of 15 FSK smart transmitters. All inputs (process data and module to transmitter communication) are in the frequency shift keyed format and share the field bus. Refer to the NTFB01 Field Bus Termination Unit instruction for specific limitations on field bus communications. All field devices must be Bailey-Fischer & Porter when using this mode.In the FSK analog point-to-point mode, the IMFEC11 module can interface up to 15 discrete analog process inputs from FSK smart devices and communicate (digitally) with those devices. Additionally, the IMFEC11 module can interface a mixture of conventional transmitters and other external analog inputs while operating in this mode. These devices can input only process data to the FEC module; they cannot communicate to the module. In point-to-point operation, each device is individually wired to the analog input termination unit or module.
FEATURES
The design of the FEC module, as with all INFI 90 OPEN modules, allows for flexibility in creating a process management system. The module supports Bailey-Fischer & Porter FSK digital smart transmitters and other smart devices, conventional transmitters and standard voltage or current inputs. The FSK digital capability (IMFEC11) eliminates conversion errors and increases process control accuracy. Access is always available to the real time process status. In the field bus mode, all information (including the process variable) is transmitted digitally between the FEC module and the field devices. The FEC module stores process data, control commands and transmitter configuration data in memory. It works to restore communication with a transmitter if a communication failure occurs. Upon restoring communication with a failed transmitter, the FEC module checks the transmitter configuration before the control module (MFP/MFC) resumes updating the process control.
