OVERVIEW
The IMMFP02 Multi-Function Processor Module (MFP) is one of
the workhorses of the INFI 90
®
control module line. It is a mul-
tiple loop analog, sequential, batch and advanced controller
that provides powerful solutions to process control problems. It
also handles data acquisition and information processing
requirements 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
system uses a variety of analog and digital I/O modules to
communicate with and control the process. The MFP module
communicates with a maximum of 64 modules in any combi-
nation (see Figure
The MFP module has three operating modes: execute, configure
and error. In the execute mode, the MFP module executes con-
trol algorithms while constantly checking itself for errors. When
an error is found, the front panel LEDs display an error code
corresponding to the type of error found. In the configure mode,
it is possible to edit existing or add new control algorithms. In
this mode, the MFP module does not execute control algorithms.
If the MFP module finds an error while in execute mode, it auto-
matically goes into error mode. Refer to the
of this
instruction for operating mode details.
A one megabaud CPU to CPU communication link allows the
MFP module to accommodate redundant processors. This link
enables a backup MFP module to wait in a hot standby mode
while the primary MFP module executes the control algorithms.
If the primary MFP module goes off-line for any reason, a bump-
less transfer of control to the backup MFP module occurs.
INTENDED USER
Personnel installing, operating, or maintaining the MFP mod-
ule should read this manual before performing any installa-
tion, operation, or maintenance procedures. Installation
requires an engineer or technician with experience handling
electronic circuitry. Formal training in INFI 90 systems and
configuration (especially function codes) would help when con-
figuring the MFP module.
HARDWARE DESCRIPTION
The multi-function processor module consists of a faceplate
and circuit board.
