The VENDOR shall provide for installation and software development in compliance with all the applicable specification above mentioned.

CONTROL SYSTEM FEATURES

CONTROL SYSTEM PHILOSOPHY

The control system consist of n. 2 control panels totally independent, with n. 1 programmable logic controller (PLC ) and n.1 operator panel (HMI) on board for each panel.

This specification cover the material selection, design configuration, installation and software development of both PLC and HMI installed in CP-001, CP-002.

PLC is a deterministic computer designated to handle large numbers of I/Os (input and outputs). Typically, it works with digital and analog field signals. The scope of supply include PLC software also it is divided into firmware, development software and application software. Firmware is essentially the operating system that resides in the PLC for the purpose of managing the various combinations of PLC hardware configurations and for fetching and executing the application software. The development software is the software tool PLC programmers used to write logic, sequences and controls to access physical I/O. The software created by the programmer is known as the PLC application software.

HMI is the interaction point for operations, providing the direct control hardware for the plant. From the HMI the Operations group obtains the intelligence of the sensor/device level and direct access to the sensor/device level of hardware. Additionally, data collection and analysis tools are presented in the HMI hardware/software.

From HMI operator can enter set points; start and stop individual equipment; monitor unit operations; and place it in Auto/0/Manual mode.

HMI (operator panel) is graphical touch screen based software running on a dedicated Operating System platform. This electronic device collects data from the PLC or any field instruments for the purpose of presenting operational information and controls of field instruments and devices. It is also capable of data analysis, historical date logging, trends, alarm handling, etc. Standard operator panel device provide the tools to design, program and animate graphical human machine interfaces with device controls, process schematics as well as various forms of data presentations and management.

The PLC & power control panels are dedicate for the following plant section :

CP-001 for Potable water unit

CP-002 for Water treatment unit (Biocide injection)

Each control panel has its own dedicated PLC with its associated I/O modules.

The software is organized and built in a similar methodology based on the S-88 standard. Software are defined into 4 layers:

Control module

Equipment module

Units

Process cells

A control module is a device (e.g. a valve, motor, flow rate, etc). Each device has a unique definition for controlling I/Os and for interfacing with the HMI for visualization.

The equipment modules are defined based on a collection of control module to perform a sub-process activity. An example would be a Filter.

A unit is a collection of equipment modules that will perform a major process activity such as a group of equipment as dosing pumps.

The final layer is the process cell that consists of a plant section. That it will produce a batch or product for example potable water unit or biocide injection.

The above development stems applies to HMI and PLC development. In addition, HMI will also be programmed and configured for alarming, historical trending, security features, event logging, diagnostic, etc. etc. .

ARCHITECTURE

The control system architecture shall allow system functions such as data acquisition and control by a graphical panel view interface that we calling HMI (human machine interface)

The system shall also support a fully interface with customer DCS for remote operation using standard ModBUS protocol (RS422/485).

The HMI seat on top of the system and through Ethernet TCP/IP, it its linked to the PLC systems.

The data communication rate is typically 100Mb. Each computer stations and PLC system have to be configured with a unique IP address to identify itself to the rest of the users in the network, IP address must be in accordance to customer address list.

The HMI (operator panel) and PLCs will be installed with Ethernet LAN connection with relevant switch Ethernet device for increased reliability. PLC station will be predisposed for DCS Client/Server communication, suitable interface RS 422/485 for communication with customer DCS must be provide on each PLC, ModBus protocol is request.

The PLCs are field programmable through the Ethernet data highway without removing the system from service, this is very usefull in the case of system maintenance and system upgrades. Most of the system upgrades can be made without effecting system operation.

All PLCs and all HMI are powered by UPS (UN-interruptible power source) a dedicate 220VDC incoming line by customer care.

PLCs shall be GE Fanuc VersaMax type, architecture and configuration should be in accordance with:

doc. N. 2219M-H01-A Control system configuration type.

Further material shall be include by VENDOR to complete the system configuration, a fully list of component shall be submitted to us for approval.

HMI SOFTWARE
