The IMFEC12 High Level Analog Input (FEC) module inputs 15 channels of analog signals only to the multifunction processor(MFP) or multifunction controller (MFC) module.
The IMFEC11 High Level Analog Input (FEC) module inputs 15 channels of analog or frequency shift keyed (FSK) digital signals to the MFP or MFC module. The IMFEC11 module performs all the functions of the IMFEC12 module and also provides communication with the Bailey-Fischer & Porter line of FSK digital smart transmitters and other smart devices in afield bus or point to point configuration
GENERAL OPERATION
Upon receiving initialization from the controlling module (MFP/MFC), the FEC module stores that information in memory and checks the configuration of each input channel.
If all input channels check good, operation begins. If the FEC module detects a configuration error, that error appears in the module status report.
Under normal operation, the controlling module sends trans mitter commands and requests process input data and status information from the FEC module.
The FEC module continu ously reads each input channel, does the necessary conver sions and stores the data in memory.
When the controlling module makes a request for data, the FEC module sends it the most current information that it has in memory.
If a communication failure with one of the transmitters occurs,the FEC module works to restore communication while con tinuing normal operation.
It checks the transmitter configura tion upon restoring transmitter communication and normal process control continues.
