From: Multiple Passwords by Bruce L

When multiple password levels are needed, there are only two choices. You can create a Password Entry Button for each password level or use a Numeric Entry and compare the entered password against the password levels in the logic to set the desired levels. However, the negative to using the Numeric Entry for passwords is that the digits that are entered on the screen while the users touches the screen. This can be a BAD problem. Here is a sample program that will draw a black line on the screen

Westermo & Unitronics Play Well Together

My company (AMPS Industrial Controls) is working with Speiser Electric Company and Gerken Paving Products to update the entire control system running the stone quarry in Custer, Ohio. This is a big project because a huge section of conveyor and crusher are being added to the existing equipment.Since the work needed is extensive, they have decided to take the opportunity to update all the controls and add wireless communication between each PLC in the quarry. One central PLC with color touch-scre

Great new products on the way...

Wow, I can't tell you how eager I am to get my hands on the new products coming our way from Unitronics. I've been biting my tongue not mentioning them for a couple months so that Unitronics could release the information on their timetable but...Both products were displayed at the PackExpo convention in Chicago earlier this month and Jas is blabbing about them over on the Forum. So I guess it's safe for me to reveal my enthusiasm.There could be more than what I know about but I'm told these thre

Data Tables & Learning from Mistakes

Twelve years ago when I started writing basic ladder programs for PLCs I made a lot of mistakes. Seemed like I was always getting halfway through a project only to realize I'd taken the wrong approach and needed to take two steps back before I could move forward. Frequently this resulted in me scrapping the entire program and starting over. I told myself that was fine. I was learning, right? Well... a dozen or so years later I'm still learning. Now I say, "You never want to stop learning," but I

Ummm - what time is it?

I just programmed a timed filtration system, and was very pleased at how simple the code is to handle a simple on/off timer with selectable day-of-the week: Pretty neat, huh? I coupled that with a simple screen letting the user set start and stop times and select the days to run: and the lion's share of the job was done. But there's much more to Unitronics timekeeping than just simple timers. In the forums, there's been some discussion of the difference between RTC and UTC, the use of U

The Fascinating World of Twitter

Well, I never thought it would happen but people have convinced us to enter the world of Twitter. We'll be tweeting often about Unitronics, control system design and the electrical control panels we build. We'd be honored to have you follow us @matthew_AMPS.

Unitronics in General Motors

An interesting thing happened to me a couple weeks ago. Well, let me back up... We prefer to do all our control system design around the Unitronics Vision line. Specifically, we've found the V350 and V570 products to be the most suitable for typical applications. They're simply the most economical, full-featured products out there. So when we were approached by a new customer to help with their machine controls we immediately thought of Unitronics. Simple application, really. Just use the PLC

You know, that's not Windows...

If you were to look over my shoulder while I'm working at my desktop or laptop PC, you'd probably notice pretty quickly that my computers don't look quite like most. Firstly, my keyboard doesn't have its letters in the usual "QWERTY" layout - I use the Dvorak layout, optimized for faster typing with minimum finger movement. I credit that (along with the refusal to use a trackpad) with curing my carpal tunnel syndrome - it took a month or so to switch over, but I've never regretted it. There's

The term HART is great for bad puns

I was offered an unused ABB pressure transducer with HART interface (see http://www.hartcomm.org/). HART stands for Highway Addressable Remote Transducer. Showing the ability to read all values from such a device using Unitronics is an advantage for applications in the mining and resources sectors in particular.Using the Turck BL20-E-GW-EN and BL20-2AIH-I a simple ModbusTCP gateway module was possible. Whilst all HART values are accessible as Modbus registers, the conventional 4..20mA input v

Feelin' a little Loopy!

When Programmable Logic Controllers were first introduced, their programs were geared toward the replacement of simple relay circuits. Logic statement 0 was processed first, then logic statement 1, and so on until an END instruction was reached. Then the PLC's supervisory software, or "Operating System", would do some housekeeping - update timers and counters, send outputs to the physical devices, read inputs from the physical devices, and run the user's stored program again. Logic statement fiv

Hey, you - what's the password?

One of the requirements I frequently find in customer specifications is that Operator Terminals shall have eight hierarchical levels of password protection. The idea there is that an operator, for example, enters the level 1 password to do operator things, and a supervisor can enter a level 2 password to do anything the operator can do, plus supervisor stuff. I have yet to actually see an application where all eight levels were used for anything, but somebody somewhere once decided that eight

So I went to the Library for some Strings...

So I'm easing my way back into VisiLogic land, in-between phone calls from TV trucks. The other morning I get a call from one of our techs on a startup somewhere in Texas, telling me that the customer is requesting that all the panels on the "A" side of the facility have their primary power feeds fed from the "A" side breaker panels, and that on the "B" side, "A" side breakers should go to the secondary power inputs. For this they wake me up? Just swap the feeds on the "B" side, right? Unfort

Machine Controls - Overhead Conveyor

In this entry, I would like to highlight one of our machine controls projects that used the Unitronics V130 OPLC: AMPS has been working with JML Services and their die storage systems for over ten years. These machines have been installed in most states all over the country to help printing companies keep track of their die plates. A corrugated box manufacturer, for instance, may have over 1000 die plates to store and keep track of. This could take up valuable floor space and be a nightmare t

Multi Connection Listener on the .Net Communication Driver

You are probably saying to yourself "Hey, you promised that the next episode of 'Build your own SD Card Explorer' will be published, so how come Saragani posts about something else?"Well, I actually said that the next episode will be posted next week :-)It is going to have a lot of code and it will be a lot of work writing it so I might split it to few pieces.Besides, I can use this blog entry to post about new features of the Com Driver.I wrote this multi listener a while ago, but the source co

Build your own SD Card Explorer

People who see the SD Card Explorer in action usually sometimes wish to have the same functionality in their own application.Some of them contact Unitronics in order to get some details on the protocol, or ways that they can do the same, while others fear from the worst: that it's a lot of work.I know very few people that will be happy to write the whole protocol by themselves.The only guy I can think of in that matter is Ash Nielson... I have no idea where he gets his strength and energy from,

Controls Engineer? How'd you get _that_ job?

It's been a couple of weeks since I've run VisiLogic - that's a bit unusual for me lately, since I generally don't go a day without doing something or other on a Unitronics system. The reason is that I've been spending my time on two of the nation's newest mobile HDTV production trucks, installing control systems which combine an embedded Linux computer with networked frames of Mitsubishi PLCs and a cross-platform PC GUI written in Perl/Tk. Working as a controls systems integrator has its bene

Wireless Serial Communication

Hello everyone, My name is Matthew and I am a long-time Unitronics distributor, customer and all around fan-boy. My company uses their controllers every chance we get, selling them to customers and using them in the control system design work we do for OEMs. Seems like lately every project we do has some sort of communication with an outside device. This prompted us to begin working with a company that's an expert in wireless devices to come up with a cost-effective wireless serial data commun

Howman Controls - We Do Unitronics, Right?

Hi! I'm Phil Salkie, Lead Engineer for Howman Controls in Edison, NJ, USA ( http://www.howman.com ). We're a small distributor and manufacturer of industrial controls products, and a UL-508A panel shop. Howman has been in business for about 30 years, and I've been here for 25 of them - if you've watched a sporting event on TV, dealt with a large bank, had a wound sewn up, or bought a banana, a gallon of gasoline, or a computer chip, there's a good chance that some of our hardware or software

Clearing the Decks

It has been a couple of months for cleaning up unfinished business. Old repairs have been completed, non-working demos restored to life, papers filed, notebooks purged and so on. My desk is now a streamlined surface of effiicient productivity. Just the perfect time to start a new forum and blog.I am looking forward to new level of interaction and a place to ramble about stuff without getting in anyone's way. Hopefully some of my ramblings might even be useful.

First Blog Entry!

Thought I would start off my blog with some thought generation! What sort of Technologies / Languages are sought after these days? I am basically interested in what any of you more "Techy" Unitronics users prefer as a Software Development language. My reason for this is to see what libraries / applications to support Unitronics hardware are missing on Non-Windows or Non .NET environments Do many of you long for a "Remote Operator" app on Mac or Linux (Maybe even the iPhone). Do many of you w
