HMI – PLC Communication Example (Ethernet)

It´s been a long time since we post the last communication example.
And this time, taking advantage for the new coming soon release of DVS (Unmanagged Ethernet Switches) and new DVP-SE (PLC with Ethernet Embeded), we decide to show everybody how to communicate one PLC and one HMI trought Ethernet.

To make it easy for everybody, even the ones without English skills.
We thought the best will be to show everybody using video tool.

Full screen recommended

And If you need the HMI program, don´t hesitate to download it here

By the way, We´re planning to put all communication links in one page to easy link to everybody.

Sequential Programming – PLC tips & tricks

Again we dedicate this post to the beginner PLC programmers.
Almost all PLC programs use to follow sequential structure (on state following to another one).
In fact SFC language is based on this concept.

Unfortunately SFC is not always enough user friendly for beginners, and there´s no manuals who show that kind of tricks when you start programming.
So or you have a experienced teacher, or you´re going to expend a lot of time trying to find out the easy way to do it.

In this case, we want to make the thinks easy, so we made the typical traffic lights program following the Sequential structure.
Once you understand the way of programming, enter to SFC or even Function blocks it will be a piece of cake ;)

Step 1: Establish the different states

Step 2: Put the different states in order (flux diagram)

Step 3: Add transition conditions

Step 4: Program it!!

The advantage of this method, are the following:
1. If you programs freeze, you can find the bug easily checking the program index.
2. You can debug each state just changing the MOV value.
3. You can add middle steps easily.
4. you can reboot our program only changing the program index to 0.

I should recommend to try it by your own, and once you finish, you can download the solution

And let us know if it has been useful!

PLC Instruction finder

Today I would like to publish a nice job from the technical team in the Delta Hungarian distributor Control Solution.
To show everybody how our partners can improve our documentation in their benefit.

Probably some of you spend a lot of time looking for the proper instruction and it´s relative example in the manual to check how to work with it.
Going page to page trying to find whatever you are looking for.

So to save this hard job to their customers Control Solution people just develop this simple on-line manual easily indexed using html file to find it.

You can link directly from here.

I add this link on the blog pages to make the consult faster
