$1.$ Understand the elements and connectivity of industry fieldbus system

Fieldbus is an industrial network system for distributed control used in factory automation

applications. It connects multiple fieldbus$-$enabled instruments within a network and allows

the controller to communicate and control with these instruments in$-$real time.

Fieldbus connection is typically multi$-$drop which requires only one communication point at

the controller to multiple fieldbus instruments the same time. This reduces both the length

of the cable required and the number of cables required.

Fieldbus also supports connectivity and high bandwidth data transfer between controllers

that provides opportunities for full integration of production activities.

The Mitsubishi CC$-$Link $($Control and Communication$)$ is an Open Automation Networks

which are a group of open industrial networks that enable devices from numerous

manufacturers to communicate. They are used in a wide variety of industrial automation

applications at the machine, cell and line levels.

Mitsubishi CC$-$Link fieldbus operates at different level of the production activities.

The network connectivity may include:

o PLC to Remote I$/$O modules via CC$-$Link IE Field and CC$-$Link

o MES$/$ SCADA$/$ HMI to PLC via Ethernet

MES $=$ Manufacturing Execution System

SCADA $=$ Supervisory Control and Data Acquisition

HMI $=$ Human Machine Interface

o PLC to PLC via CC$-$Link IE Control

Such connectivity provides seamless data communication between Enterprise level,

Control level, Device level and Sensor level.

Mitsubishi CC$-$Link fieldbus is an essential part of achieving Industry IoT $($IIoT$).$

The CC$-$Link Partner Association $($CLPA$)$ offers a family of open$-$architecture networks.

These originated with the CC$-$Link $($Control & Communication$)$ fieldbus in $1996,$ developed

by Mitsubishi Electric Corporation.
