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 Reduces Boiler Control Cost & Development Time with the Vision1040™

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.

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.”

PLC+HMI all in ONE

Save time and money with this all in ONE PLC+HMI
Save time and money with this all in ONE PLC+HMI

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 PLC+HMI all in ONEusing 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
Unitronics CANbus networked IO and controllerscontrollers 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.

How easy it is to connect our range of PLC and integrated HMI’s to 3rd party intelligent sensors or nearly any other device’s via RS232 / RS485.

Following on from the recent exhibitions and interest that has been expressed in communication options. We thought it would be a worthwhile exercise to emphasise how easy it is to connect our range of PLC and integrated HMI’s to 3rd party intelligent sensors or nearly any other device’s via RS232 / RS485.

Unitronics engineers have worked hard to reduce the pain involved in serial communications by producing a function block that allows you to configure a message using a comprehensive set of pre-defined conversion and calculation tools.  The net result is a neat little box in the middle of your program that sends out a question and returns the answer to a place of your choice.

Plus the added value of free programming software

Unitronics Snap-In I/O Offers More Flexibility for Vision Series Integrated PLC+HMIs.

The convenience is clear: Unitronics PLC + HMI package exempts machine manufacturers from setting up Panel-PLC communication- saving programming time, cabinet space and money. This single Ladder Logic programming environment is part of the Unitronics “all-in-one package”, and is available at no additional cost.

V200-18-E62B with V1210-T20B from i4 Automation
PLC & HMI with easy to use snap in module

Unitronics Snap-in I/Os are a convenient, affordable way to “snap” your choice of a variety of I/O combinations directly to the back of most “Vision” series PLC + HMI controllers. Most “Vision” series controllers enable the user to pick and choose from an assortment of Snap-in I/O combinations to fit their specific application needs. A whole system’s requirements can be fulfilled with just one “Snap”! Connecting directly to the back of a Unitronics Vision200, Vision500, Vision1040 or Vision1210 series PLC+HMI, the new V200-18-E62B Snap-in module now supports a total combination of 62 analog and digital inputs and outputs. Specifically, this combination includes: 30 Digital inputs (including 2 shaft encoder inputs), 2 analog inputs, 28 digital outputs, and 2 high-speed digital outputs.

With additional expansion modules, mounted locally or remotely up to 1000m from the controller, configurations can be expandable up to 1024 I/O. Unitronics solitary Snap-in I/Os (without expansion units) typically range from 30 – (now) 62 I/O with the new V200-18-E62B. Basic Snap I/O options can include: digital and analog inputs and outputs, high-speed I/O, PT100/Thermocouple capabilities, and weight measurement.

Additional features of the “Enhanced Vision” series controllers (V1210, V1040, V570, V350, V560, V290 Color, and V130) include: A USB programming port, recipe capabilities, Micro SD card memory storage for data logging and back up, complete PLC cloning and more. Communication options include Ethernet, cellular, and industrial protocols such as MODBUS, DF1 slave, J1939, and CANopen, UniCan.


High density I/O as part of the PLC & HMI system

Now able to provide even more flexibility when configuring a system’s precise requirements, the new Snap-in module offers particular appeal wherever budget is a primary factor. Being equipped with many I/Os allows this snap-in module to help cut costs by taking the place of lower I/O count modules and adapters that may have otherwise been purchased.
