NOMENCLATURE
The following modules and equipment can be used with an
ASO:
Term
Definition
LSB
Least Significant Bit; the bit of a binary number that carries the least numeri-
cal weight.
Master Module
One of a series of controller modules designed to direct field processes
through a slave module. The multi-function processor is an example.
MFP
Multi-Function Processor Module; a multiple loop controller with data acqui-
sition and information processing capabilities.
MMU
Module Mounting Unit; a card cage that provides electrical and communica-
tion support for INFI 90 modules.
MSB
Most Significant Bit; the bit of a binary number that carries the most numeri-
cal weight.
OIS
Operator Interface Station; integrated operator console with data acquisition
and reporting capabilities. It provides a window into the process for flexible
control and monitoring.
PAL
Programmable Array Logic; an integrated circuit that performs logic func-
tions based on a program that is downloaded to it.
PCU
Process Control Unit; rack type industrial cabinet that contains master, slave
and communication modules, and their communication paths.
RAM
Random Access Memory; processor memory that has both read and write
capability. This memory is volatile; its contents are lost when power is
removed.
Slave Expander
Bus
Parallel address/data bus between the master module and the slave that
point data and slave status data are exchanged over.
TM
Termination Module; provides input/output connection between plant equip-
ment and the INFI 90 process modules. The termination module slides into a
slot in the termination mounting unit.
TU
Termination Unit; provides input/output connection between plant equipment
and the INFI 90 process modules. The termination unit is a flat circuit board
for panel mounting.
