HOW TO: Use the E1000 HMI Dip Switches

As you may or may not know, there are four dip-switches which can be found on the back back of an E1000 HMI. If you’ve ever wondered what they’re for, don’t fret – this guide will outline their functions.

There are five configurations which can be made using the dip switches. The process is fairly straight forward:

  1. Power down HMI
  2. set dip switches – done by moving the switch into the up position
  3. power up HMI
  4. follow on screen instructions (if any)

 

And here are the five configurations:

 

0000:

Run mode, normal operation.

 

0010:

System restore, resets the file system and registry & re installs the system program – basically its a ‘restore to factory defaults’ setting. Beware, you will lose your entire project off the HMI when using this mode.

 

0100:

Image Load Mode, this mode allows the firmware of the HMI to be upgraded. Beware, this mode will also cause you to lose your whole project.

 

1000:

User Menu Mode: this mode allows you to enter several menu’s to calibrate the HMI, these include options to edit: Network settings (IP address), calibrate touch and set the date/time. From this menu you’ll also be able to load a project from a memory card, update the EM module and erase the project. Furthermore you can enter some of the aforementioned mode’s including Transfer mode and Run mode.

 

1110:

Self test, this mode does exactly what it says on the tin. It allows you to test the features of the HMI – to name a few: LED’s, Buttons, Buzzer, serial comms, battery condition, EEprom, touch screen, back light and colour test.

 

 

This concludes the guide. We hope it was helpful.

E1000 HMI – Access Trends, Recipes & Alarms without ‘HMI Tools’ on an

‘HMI Tools’ is a software package used to transfer program and data files between a PC and an E1000 HMI. Amongst other things, it can be used for transferring trend information, alarm lists, recipe data, html files, Java applets and bitmaps to and from a terminal via FTP (File Transfer Protocol). BUT there’s another way…

Now, if you’ve used HMI Tools before I’m sure you’ll agree it’s a powerful and useful tool, there’s no doubt about that, but for those of you who haven’t got it installed and just want to quickly extract a few files from your E1000, you don’t want to have to run an install from disc – especially if you’re out on site and don’t have the disc with you! And the other good thing is, you can do this method over Ethernet – no need to wait around for serial comms!

So let’s jump straight into it! Here’s what you need:

  • A PC with an Ethernet port
  • An E1000 HMI (not applicable with the E1012 or E1022)
  • Cross-over Ethernet cable
  • E-designer software installed on your computer

Step 1:

We need to first find out what IP address the HMI currently has assigned to it, the easiest way to do this is from E-designer. Click on Setup > Peripherals, you should see the following window:

E1000 Peripheral configuration step 1

As you can see, my IP address was 192.168.8.135.

 

Step 2:

Next we need to match the IP address of your PC to the range the HMI has, i.e. it needs to be 192.168.8.X. This can be done from your Network and Sharing Center: From the screen shown below (left), click the properties button (circled), to show the following (right):

E1000 Wireless network connection status step 2

Wireless network connection status step 2

From the second screen (right), double-click on the “Internet Protocol Version 4 (TCP/IPv4) to show the following screen:

E1000 Internet protocol version 4 step 2

Internet Protocol Version 4 Step 2

 

From this screen the only thing you need to enter is the IP address which matches the range assigned to the HMI, in my case it was: 192.168.8.10. The subnet mask will populate itself once you tab across to it. As for the ‘Default Gateway’ and the ‘DNS’ settings, they can all be left untouched.

 

Step3:

So at this point we have made a connection between the HMI and PC over Ethernet – feel free to put that serial CAB30 back in your bag and connect the Ethernet cable. The next step is to prepare the HMI for use over FTP. From the project manager, double-click ‘Network Services’ (left) to show the window on the right:

E1000 E-designer Network Services step 3

E-designer Network Services step 3

From the Network Services window ensure that the ‘FTP Server’ option is ticked, then press the Exit button. Now simply transfer the whole project to the HMI – be sure to select TCP/IP transfer from the communication properties before trying to transfer.

 

Step 4:

Now we can now use any internet browser to access the files we want to view, but I found that using windows explorer was quicker – either way the process is the same. Type in ftp://[Insert HMI IP address here] into the address bar. Like so…

E1000 Windows explorer FTP Step 4

Windows explorer FTP Step 4

As you can see, we now have access to Alarms, Images, Trends, Recipes, HTML and if you click into the INFO.TXT file you even have access to basic information about your HMI such as: firmware version, IP address and spare memory etc. If you click into these folders you’ll find they contain .CSV files, which you’re able to open in a Spreadsheet, Ta Dah! This concludes this blog post, thanks for tuning in!

New solid-state relays for high switching frequencies from Phoenix Contact

Phoenix Contact have now added to their range of PLC solid-state relay products incorporating a new feature that enables you to safely detect pulses up to a limit frequency of 100 kHz where conventional solid-state relays are frequently out of their depth

 

Some modules also offer a push-pull output. This is suitable for signal inputs to PLC meter cards that are fitted with a capacitor on the input side. This means that disturbances are effectively suppressed.

The new PLC solid-state relays can detect switching signals up to 100 kHz

Phoenix Contact new solid-state relays  for  high  switching  frequencies

Additional advantages of the series of PLC relays

  • Wear-free switching for reliable system operation
  • Safe electrical isolation
  • Time-saving wiring, thanks to a convenient plug-in bridge system
  • Space-saving design width of just 6.2 mm

Available with either a screw or a push-in connection

E1000 HMI – Program backup / upload via USB stick

Sometimes you’re out on site with a dead laptop and you’ve forgotten your laptop charger, or you’ve forgotten that the E1000 HMI’s use a CAB30 cable and not the good old CAB5, OR you simply don’t want to fire up your laptop for a 2 minute job! Whatever the case, we’ve got you covered because the E1000’s offer you the facility to upload/download projects via a USB stick! Here’s how…

Now, obviously, at some point or the other it will be necessary to actually save the project to the USB stick, so it sounds like this would be a good place to start this post:

 

Step 1 – From the ‘Transfer’ Menu, select ‘Export project transfer file’

E1000 HMI – program backup / upload via USB stick - Step 1

Find the path of your removable device and hit save! Be sure to save it in the route directory.

 

Step 2 – Insert the USB stick into the USB port of the HMI, you should then see the following message

E1000 HMI – program backup / upload via USB stick - Step 2

The terminal will then show that a file structure is not available, it will then request that one be created:

Press OK and the project will be downloaded automatically into the terminal and run through the boot-up with the new project.

Congratulations, you have now successfully loaded a project into the terminal!

Mitsubishi L-series Data logging & Memory Card Use

Did you know that you can use an SD/SDHC compatible memory card to quickly and easily back-up the CPU programs and parameters on a Mitsubishi L-Series processor?

Mitsubishi-Electric-L-Series-SD

The back-ups can then be just as easily restored or used to program other CPUs. The memory card can also be used to hold data captured with the data logging function.

This additional feature will give you the following benefits:

  • Quickly recovering a failed PLC
  • Quickly load a new program in a new machine without needing a PC
  • Email a program to a customer who will then be able to copy it to their SD card to load into the PLC

 

Data Logging:

Take a look at our video below for a FULL walk through on how to use the built-in data logging function of the L-series PLC:
