Introduction Section 1
Overview
The INICI03 Cnet-to-Computer Interface is a Harmony rack
communication interface. It provides a host computer or
human system interface (HSI) access to Control Network (Cnet)
in the Symphony Enterprise Management and Control System.
Figure 1-1 shows the computer interface.
NOTE: The INICI03 interface is fully compatible with existing INFI 90 OPEN
Strategic Enterprise Management Systems using the INFI-NET communication
system.
Control Network
Cnet is a unidirectional, high speed serial data network that
operates at a ten-megabaud communication rate. It supports a
central network with up to 250 system node connections. Multiple satellite Cnet networks can link to a central network.
Each satellite network supports up to 250 system node connections. Interfacing a maximum number of satellite networks

Intended User
gives a system capacity of 62,500 nodes. Redundant Cnet communication capability is a standard feature.
On the central network, nodes can be satellite networks, Harmony control units, human system interfaces, and computers
each connected through a Cnet communication interface. On a
satellite network, nodes can be HCU cabinets, human system
interfaces, and computers.
Computer
A computer can access Cnet for data acquisition, system configuration, and process control. It connects to Cnet through a
Cnet-to-computer interface. The computer connection to Cnet
enables plant personnel, for example, to develop and maintain
control configurations, manage the system database, and create HSI displays remotely using Composer engineering tools.
There are additional Composer and Performer series tools and
applications that can access plant information through a
Cnet-to-computer interface.
Human System Interface
A human system interface such as a Signature Series workstation running Conductor Series software provides the ability to
monitor and control plant operations from a single point. It
connects to Cnet through a Cnet-to-computer interface. The
number of workstations in a Symphony system varies and
depends on the overall control plan and size of a plant. The
workstation connection to Cnet gives plant personnel access to
dynamic plant-wide process information, and enables monitoring, tuning, and control of an entire plant process from workstation color graphics displays and pushbutton keyboard.
Intended User
Personnel installing, operating, or maintaining a Cnet-to-computer interface should read this instruction before performing
any installation, operation, or maintenance procedures. Installation requires an engineer or technician with experience handling electronic circuitry and familiarity with communication
networks.
Interface Description
WBPEEUI250019A0 1 - 3
Interface Description
The Cnet-to-computer interface is made up of the INNIS01 Network Interface module, the INICT03 Computer Transfer module, and the IMMPI01 Multifunction Processor Interface
module (Fig. 1-1). This interface gives a host computer access
to point data over Cnet. The computer connects through either
an RS-232-C serial link at rates up to 19.2 kilobaud or through
a SCSI parallel port. The interface is command driven through
software on the host computer. It receives a command from the
host computer, executes it, then replies to the host computer.
NOTE: Conductor NT interfaces to Cnet through an INICI03 Cnet-to-Computer
Interface. Conductor VMS does not use the INICI03 interface but instead has
its own dedicated version of the Cnet-to-computer interface (IIMCP02 and
IIMLM01).
INNIS01 Network Interface
The INNIS01 Network Interface module is the front end of every
Cnet communication interface. It is the intelligent link between
a node and the Cnet network. In this case, it works in conjunction with the INICT03 module. The INNIS01 module allows any
node to communicate with any other node within the Symphony system.
The INNIS01 module is a single printed circuit board that occupies one slot in a module mounting unit (MMU). The circuit
board contains microprocessor based communication circuitry
that enables it to interface with the INICT03 module over a
dedicated I/O expander bus.
Two latching screws on the faceplate secure the INNIS01 module to the module mounting unit. There are 16 LEDs on the
faceplate that display error codes and event/error counts.
The INNIS01 module has three card edge connectors for external signals and power (P1, P2, and P3). Connector P1 connects
to common and +5, +15, and -15 VDC power. Connector P2
connects the INNIS01 module to the I/O expander bus to communicate with the INICT03 module.
The INNIS01 module connects to its Cnet communication network through a cable attached between its P3 connector and
an NTCL01 termination unit. Communication between nodes
1 - 4 WBPEEUI250019A0
Interface Description
is through coaxial or twinaxial cables that connect the termination units of each node.
INICT03 Computer Transfer
The INICT03 Computer Transfer module handles all communication with a host computer. The module is command driven
through software on the host computer. The INICT03 module
receives a command from the host computer, executes it, then
replies. The INICT03 module firmware enables the host computer to issue commands for data acquisition, process monitoring, and process control, and to perform system functions
such as security, time-synchronization, status monitoring, and
module configuration. The INICT03 module can store up to
30,000 point definitions (depending on point types). It uses an
IMMPI01 module for host computer connection.
The INICT03 module is a single printed circuit board that occupies one slot in the module mounting unit. The circuit board
contains microprocessor based communication circuitry that
enables it to directly communicate with its INNIS01 module, to
directly communicate with an IMMPI01 module, and to interface to Controlway.
Two latching screws on the faceplate secure the INICT03 module to the module mounting unit. There are 17 LEDs on the
faceplate and a stop/reset pushbutton.
The INICT03 module has three card edge connectors for external signals and power (P1, P2, and P3). Connector P1 connects
to common, +5 VDC power, and Controlway. Connector P2
connects the INICT03 module to the I/O expander bus to communicate with the INICT03 module. Control and data signals
connect from the INICT03 module to the IMMPI01 module
through a 60-pin ribbon cable. The cable connects between the
INICT03 P5 connector and the IMMPI01 P6 connector.
IMMPI01 Multifunction Processor Interface
The IMMPI01 Multifunction Processor Interface module handles the I/O interface between the host computer and the
INICT03 module. The IMMPI01 module supports either SCSI or
RS-232-C computer interface. When communicating through
the RS-232-C port, the module can act as data communication
equipment (DCE) or data terminal equipment (DTE).
Features
WBPEEUI250019A0 1 - 5
The IMMPI01 module is a single printed circuit board that
occupies one slot in the module mounting unit. The circuit
board contains microprocessor based communication circuitry
that enables it to communicate with its INICT03 module
through the ribbon cable connection.
The IMMPI01 module has three card edge connectors for external signals and power (P1, P2, and P3). Connector P1 connects
to common and +5 VDC power. Connector P2 is not used. Connector P3 is used to cable connect the module to an NTMP01
termination unit. The P6 connector is used to cable connect
the IMMPI01 module to the INICT03 module.
For RS-232-C computer interface, the module cable connects
to an NTMP01 termination unit. Two RS-232-C ports are
located on the termination unit. The NTMP01 jumper configuration determines DTE or DCE operation. For SCSI computer
interface, the SCSI port (P5) is located at the module faceplate.
In this case, no termination unit is required.
Host Computer
The host computer can connect to the INICI03 interface in two
ways. It can connect using a SCSI communication cable from
the SCSI port on the IMMPI01 faceplate to the SCSI port on the
host computer. Or, it can connect from its RS-232-C port to an
RS-232-C port of an NTMP01 termination unit. The termination unit cable connects to the IMMPI01 module. Two
RS-232-C ports are located on the termination unit.
Features
The Cnet-to-computer interface has the following features:
• Cnet provides a plant-wide communication network.
• Cnet provides time-synchronization across the control system plant wide.
• Each node can operate independently of other Cnet nodes.
• Computer interface modules provide localized startup and
shutdown on power failure without operator intervention.
• Fast response time. The ten-megabaud communication
rate gives timely information exchange.
