The IMMFP12 Multi-Function Processor Module (MFP) is one of the
workhorses of the INFI 90® OPEN control module line. It is a
multiple loop analog, sequential, batch, and advanced controller
that provides powerful solutions to process control problems. It
also handles data acquisition and information processing
requirements while providing true peer-to-peer communications. The
comprehensive set of function codes supported by this module
handles even the most complex control strategies. The INFI 90 OPEN
system uses a variety of analog and digital I/O modules to
communicate with and control the process, and the MFP module
communicates with up to 64 modules in any combination.
The MFP module has three operating modes: execute, configure, and
error. In execute mode, the module runs control algorithms while
continuously checking itself for errors. If an error is found, the
front-panel LEDs display an error code that corresponds to the
problem. In configure mode, users can edit existing or add new
control algorithms, and during this time, the MFP does not execute
control logic. If an error occurs while in execute mode, the module
automatically switches to error mode.
A one-megabaud CPU-to-CPU communication link allows the MFP module
to work with redundant processors. This link enables a backup MFP
to remain in hot standby while the primary module runs the control
algorithms. If the primary MFP goes off-line for any reason,
control transfers to the backup module in a smooth, bumpless
switchover.

The IMMFP12 Multi-Function Processor Module operates much like a
series of functional blocks working together. To explain how the
MFP module functions, this section presents its functionality in a
block diagram (refer to below).
Still hunting for that ABB IMMFP12?
I know, finding these Multifunction Processor Modules in good
condition is getting harder every year.
But good news—I’ve actually got access to stock right now. If you
need specs, a manual, or just want to grab one before they're gone,
just let me know.
No formal emails needed, just a quick text works.
