®
The IMFEC12 circuit board only uses one working setting,
dipswitch S1 that holds the I/O expander bus address of the
module. Jumpers J2 through J4 and J6 through J20 are not
used.
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.
