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 pro-
cess 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 mod-
ules, allows for flexibility in creating a process management
system. The module supports Bailey-Fischer & Porter FSK dig-
ital 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 trans-
mitted 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 transmit-
ter, the FEC module checks the transmitter configuration
before the control module (MFP/MFC) resumes updating the
process control.
