REFERENCE DOCUMENTS
The following documents provide additional information about
INPCI02 support hardware and software.
Term
Definition
DCE
Data Circuit-Terminating Equipment - The termination point of a communication cir-
cuit such as a line driver or modem.
DTE
Data Terminal Equipment - End-user machine of a communication circuit such as a
terminal or computer.
Dipshunt
A dual in-line package with shorting bars.
Module Bus
The serial communication link between a process control module and other process
control modules.
Node
Device(s) on the INFI 90/Network 90 Plant Loop, Superloop or INFI-NET (maximum
of 63 on Plant Loop, 250 on Superloop/INFI-NET). A node can be a Operator Inter-
face Station (OIS), a Process Control Unit (PCU) or Engineering Work Station (EWS)
in any combination.
PCI
Plant Loop to Computer Interface (INPCI01/02) - A Plant Loop communication inter-
face that provides configuration and control of the Plant Loop through a host com-
puter.
PCU
Process Control Unit - rack type industrial cabinet that contains master, slave and
communication modules, and their communication paths.
Plant Loop
INFI 90 data communication highway with 63 node capacity.
RS-232-C
One in a series of standards developed by the Electronics Industry Association (EIA)
that specifies what signals and voltages will be used to transmit data from DTE (com-
puter) to DCE (modem).
Slave Expander Bus
Parallel address/data bus between the master module and the slave.
XR
Exception Report - A function block that reports a monitored point value when that
value changes and is polled by a communication or master module.
