The IMFEC12 module interfaces to conventional transmitters and standard analog inputs. It links process data and commu nication from field devices to all multifunction processors(MFP), or the IMMFC03, IMMFC04 and IMMFC05 multifunc tion controller (MFC) modules. The IMFEC12 module can be used as a direct replacement for the IMASI02 module; however,baseband communications are not supported.
For IMFEC11 modules (FSK communications), the micropro cessor sends command signals to the transmitters through the module communication circuitry. The circuitry converts com mands from the microprocessor into FSK signals. The micro processor directs the command transmission to the proper channel.
The MFP module communicates with the FEC module over the I/O expander bus. An Elsag Bailey designed integrated circuit interfaces the microprocessor to the I/O expander bus. All MFP commands and process data pass through the I/O expander bus interface and first in first out inputs or outputs.
