IMMPI01 Processor terminal module

Description

There are two multi-function processor termination modules
(IMP). The NIMP01 Multi-Function Processor Termination
Module provides a connection to the serial interface for
multi-function processors1 (MFP). The NIMP01 termination
module has two isolated RS-232-C ports. One port can be configured as a non-isolated RS-485 port. Multi-function processor modules use the ports to communicate with computers,
printers and sequential events recorders. The NIMP01 termination module also provides the connection for a station serial
communication link. This link allows the MFP module to communicate with an IISAC01 Analog Control Station or NDCS03
Digital Control Station. Figure 1-1 shows a typical IMP termination module application.
The NIMP01 termination module also interfaces with the
INIIT02 INFI-NET to INFI-NET Transfer Module. The INFI-NET
to INFI-NET transfer module (IIT) supports bidirectional communication through two RS-232-C ports. Port one passes system data only. Port two passes system data or can be used as a
diagnostic port. The central IIT module can use a variety of
means to link to the satellite IIT module such as modems,
microwave and transceivers. This module communicates
directly with a network interface I/O module on the local
INFI-NET ring through the I/O expander bus.
The INFI-NET to computer transfer module2 (ICT) provides the
electronics needed to direct the operation of the INFI-NET to
computer interface. It handles all communication with the host
computer through the multi-function processor interface (MPI)
or RS-232-C serial port. The MPI interface can act as DCE or
DTE equipment.
The NIMP02 termination module is used in addition to the
NIMP01 termination module when terminating redundant
modules.
Termination modules provide a connection from the plant
equipment to the INFI 90® process modules. The NIMP01
Multi-Function Processor Termination Module terminates a
multi-function processor, INFI-NET® to computer transfer
module, INFI-NET to INFI-NET transfer module or multi-function processor interface module. The NIMP01 Multi-Function
Processor Termination Module provides a termination point for
two RS-232-C lines or one RS-232-C line and one RS-485 line,
plus a serial link to connect an analog control station or digital
control station through an NICS01 Control I/O Termination
Module.
The NIMP02 termination module is the interface for redundant
multi-function processor modules. The NIMP02 termination
module requires an NIMP01 termination module to operate.
This product instruction explains how to install and use the
NIMP01 and NIMP02 Multi-Function Processor Termination
Modules.
