Project: Automation and SCADA System for Water Treatment Plant
PLC: Vision560™, Vision1040™ + 300 I/O
Application: The automation system permits the ability to real time monitor the process and complete control of the Water Treatment Plant. All the field equipment is connected to the PLCs: pressure, temperature and flow transducers, the power controller and the control valves. The software application from the PLC has PID loops and permits to exchange the values of the parameters with other devices from the automation system. The PLC is connected and communicates with the Citect SCADA system via UNI OPC Server.

Energy Plant Solutions of Palmerston North, New Zealand needed a cost effective automation solution for their range of package boilers. The Vision1040™ met all their needs and stayed within their budget. “Working with the Unitronics combined PLC and HMI make other systems feel old fashioned and obsolete.” – Justin Butler, Senior Electrical Engineer at Energy Plant Solutions.
WHY THE VISION1040™? The V1040 provided the right balance of screen size and number of physical buttons as well as communication ports. Because they were using the EX-A2X along with (2) IO-DI16, (2) IO-RO16, (2) IO-AI8 and (2) IO-AO6X’s, (Giving a total of 32 digital inputs, 32 relay outputs, 16 analogue inputs with 14 bit resolution and 12 analogue outputs with 12 bit resolution all neatly DIN rail mounted) the large screen allowed ample room to display the required information while keeping the fonts and elements large enough for easy reading. The physical buttons allowed them to have most buttons always available without using up any of the screen. This also helped with keeping the screen clean.
“There were significant cost savings using the Unitronics PLC,” said Justin Butler, Senior Electrical Engineer at Energy Plant Solutions. “This is for both the development software licensing (it doesn’t get much cheaper than free) and also in the time required to develop the PLC/HMI software. Making changes is so much quicker when you can add the necessary logic to the PLC program and then immediately add the new elements to the HMI without having to export or import tag data, etc.
Also if we need to move some operands we can do it in a single step and the changes are made to the PLC and HMI code immediately.” Butler goes on to say, “With Remote Operator, we can see exactly what the operator sees from our office at the other end of the country via a VPN at absolutely no cost either financially or in development time. This is a huge advantage if the client requires assistance to solve a problem. Because the PLC and I/O modules are all 24VDC, we were able to use a 24VDC uninterruptible power supply (“UPS”) to maintain power to the PLC and I/O on power failure. Because the “UPS” does not need to step the power up to 230VAC before being stepped back down again, we achieve maximum up time afforded by the batteries. It is also safer because there is no 230VAC present when the main power supply is disconnected.”
The SMS system sends the operator an actual description of the fault, rather than just a generic “boiler fault” message. This allows the operator to make a decision on how quickly he needs to attend to the fault. The fault messages on the HMI and SMS are the same and come from the string library- therefore, they do not need to be coded twice.
“Unitronics PLCs allow us to run the PLC without any I/O attached. This is great for testing before the system is deployed on site,” says Butler. “This works like a simulation where we can enter any values we like for conditions and test that the PLC acts as intended. We can also check that all the graphics work and look good on the actual screen that will be used. This means we can do 90% of the testing before we even go to the site.”
“Working with the Unitronics combined PLC and HMI make other systems feel old fashioned and obsolete,” says Butler. “The support from Unitronics, from our local supplier, to email support, to help ideas on the forum, has been absolutely fantastic.”
Cost Savings Having a combination PLC+HMI has many advantages over the traditional control. You can use the FREE programming software and FREE programming cable to get things started straight out of the box or download the software in advance and start planning and developing your project. You only have to programme a Unitronics OPLC once, as the controller is an integrated PLC+HMI giving you a further cost saving as you are now saving project time, plus free support (no maintenance contracts).
There are three ways of connecting the inputs and outputs (I/O) all very cost effective and any method can be used independently OR all three methods can be used to give optimum distributed control. On board IO is the lowest cost option by having all the wiring on the back of the PLC+HMI using one of several snap in cards or on smaller units selecting the type of display and then your type of inputs and outputs. This is not only a low cost solution but it also makes the most use of the available space. DIN railmounting allows you to either expand your I/O count or to more conveniently mount your I/O on DIN rail up to 20 meters away from the PLC+HMI using the dedicated I/O expansion port and Unitronics own wide range of cost effective I/O modules allows for an easy way to expand your control.
Lastly Remote IO can be achieved using the easily configurable CANbus option (included “free of charge” on all 5.7”, 10.4” and 12.1” models) which allows you to link several controllers together or a single controller to remote I/O islands again using Unitronics own wide range of modules. It’s fast and easy to use with Unitronics own UNIcan version being used over the CANbus network taking the strain out of configuration. Plus most controllers have MODbus built in and Profibus options as well as Ethernet, all easy to configure with simple function blocks.
The Unitronics range accepts a wide range of inputs from Thermocouples, PT100, load cell / strain gauge and standard analogue inputs and using the built in PID control it can easily become your complete machine controller. The flexibility of having PLC+HMI in ONE allows for the removal of several standalone devices with a single cost effective controller with its free programming software and several utility programmes giving you easy remote access and complete control of your equipment.

VisiLogic 9.0.1, OS 3.3.3 • V1040 support
The new Big Vision—the V1040-T20B with a 10.4″ colour touch screen—is now supported in Hardware Configuration.
This is also the first Vision to offer a USB programming port. • 65K colours (16-bit)
From VisiLogic 9 on, all images will be 65K colours (16-bit). However, images in older projects that are opened with this version will remain 256 colours (8-bit).
Note: older projects including many images, especially where images are switched rapidly to provide animation, may run at reduced speeds, and in certain cases may not function properly.
• UniVision Licensing
This new utility helps you to protect your intellectual property.
You can create a PLC license number and burn it into a secured, hidden sector in the PLC.
You can then use this license in your Ladder to control how your program functions. • New GSM/GPRS Modems We now support 2 more modems:
– Cinterion MC55i
– Sierra Wireless GL61000 • PTO Functions
Simple Motion Control via software!
You can easily implement motor control via high-speed outputs of certain Vision 130/350 models, controlling up to three independent axes. In this way you can, for example, build speed profiles that are appropriate for stepper motors.
The utility can output pulses, pulse/direction or CW/CCW.
Note that the PTO control functions are open-loop, and do not rely on positional feedback.
Available PTO features depend upon specific Vision model. • HMI Editor
New view shows the Display screen and Jumps in separate screens, selectable via tabs at the top of the editing window. • Version Compatibility
Do not download a project built with versions lower than VisiLogic 9.xx, to a controller installed with the system files released with VisiLogic 9.xx (Boot V2.002 (xx), BinLib V1.010 (xx) and OS V3.003 (xx)) and up. This will result in version mismatch.
VisiLogic V9.xx is compatible with Boot V2.002 (xx), BinLib V1.010 (xx) and OS V3.003 (xx) and up. • Modems
Certain older modems are not supported in VisiLogic 9. If you wish to update a project containing modems to VisiLogic 9, check the COM Init function to see if your modem is supported. It is highly recommended to delete and redefine the COM Init function.
Note that the information in this document refers to Vision Divisions. These are:
