The IPR interfaces transfer system data, control and configura-
tion messages, and exception reports between the central and
remote satellite systems. Many of the operating characteristics
of the IPT module are determined by the specifications in the
INFI-NET to Plant Loop remote transfer module executive block
(function code 203). Configure these specifications to fit the
needs of the application.
MODULE DESCRIPTION
The IPR interface is made up of one INNIS01 Network Interface
Slave Module (NIS), one INIPT02 INFI-NET to Plant Loop Trans-
fer Module (IPT), and one IMMPI01 Multi-Function Processor
Interface Module. The central INFI-NET system and the remote
satellite Plant Loop system each require one IPR interface.
INNIS01 Network Interface Slave Module
The INNIS01 Network Interface Slave Module (NIS) works in
conjunction with the IPT module. This allows nodes within the
system to communicate with any other node.
The NIS module is a single printed circuit board that occupies
one slot in the module mounting unit. The circuit board con-
tains microprocessor based communication circuitry that
enables it to interface with either local IPT module (one in the
central INFI-NET system and one in the remote Plant Loop
system).
Two captive latches on the front-mounted faceplate secure the
module to the module mounting unit. There are 16 LEDs on
the faceplate that display error codes and event/error counts.
Each NIS module connects to its communication loop by a
cable connected to an NTCL01 Communication Termination
Unit (TCL) or an NICL01 Communication Termination Module
(ICL). Communication between nodes is through coaxial or
twinaxial cables that connect the termination units or modules
on each node.
Power and I/O expander bus connections follow the same con-
nector assignments common to most INFI 90 modules (P1 for
power, P2 for I/O expander bus). Connector P3 connects the
NIS module to the NTCL01 or NICL01 termination device.
INIPT02 INFI-NET to Plant Loop Transfer Module
The INIPT02 INFI-NET to Plant Loop Transfer Module (IPT) sup-
ports bidirectional communication through two RS-232-C
ports on the IMMPI01 Multi-Function Processor Interface Mod-
ule (MPI). Ports one and two pass system data. Connector P4 is
