Gas metering in EGX 300 visible ? DI on PM750

[josgrafe]

We have a gas puls connected on the PM750 digital input.

In ION6 we can work with this signal. (countervalue)

Is it also possible to see this input and a trend in the EGX 300?

Looking forward to your suggestions.

Hello Jos,

There are a couple of solutions, that are not really ideal, but will work.

You can display the status and the count of the input in the real time and logging features using the Custom Device Type Generator.  With this tool, you can create a device type that can display any values that the PM750 makes available via Modbus.  You can also scale these values to make the counts more meaningful.  For example, you can multiply the number of counts on the input by a number representing something like the number of cubic meters per hour each pulse represents.  However, with this solution, you will not be able to use the Trending feature on-board the EGX300.

It is possible, however, to create a custom page to do pretty much whatever you would like.  You could create a "Trending" web page for the PM750 that reads the value of the input on a periodic basis (once every couple of seconds or so) and then display the results on a graph.  There are several graphing tools available for free on the internet that you could upload to one of the custom web page directories.  Also, the EGX300 makes the device list available to applications via the "devlist.xml" file.  You could use the contents of this file to determine the Modbus addressing information for the PM750s defined in the system.

If you would like any additional information about the Custom Device Type Generator or Creating Custom Web Pages in the EGX300, please let me or James Jeanette know.  We will forward the appropriate documents describing these features to you.

Please let me know if I can be of further assistance in any way.

I actually wrote an article on how to do that with a PM3255 a long time ago. It's exactly as Randi is describing.

Here are some of the details:

Thanks guys,

I will experiment with these options.

Maybe It will be a good add-on for the EGX300 software is there is a way to see WAGES information graphically.

(Is this covered in the Com X 200? )

Randi,

please send me the documents that you described. ( j.graefe@beenen.nl)

You can do the same type of Custom Device Type in the Com'X200, however, there's one major difference: the Com'X200 cannot do any sort of reporting (can't be used as an on-site solution). You can only do the data-logging and push the data to the cloud (REM, Energy Operation or other third party) so it might not work for what you intend to do. The Com'X500 (expected in 2014) will be the replacement of the EGX300 and will do all the Com'X200 is awesome at, and will allow local reporting.

Thank you for the information. I will offer the EGX300 for now with an eWON 2101 CD UMTS  to connect to it. ( VPN - webbased)  , Will VPN be available in the Com'X500 ?

Hi Randi,

with the second option you can display the trend but you can't do the logging of the variables.

It would better involve the digital inputs, in the logging file, for each device having digital inputs. In Italy this are asked very frequently.

The customers solve this problem creating a new device with all electrical variables and adding digital inputs, losing the trends.

Thank you Randi

Could you please send me some information about how to create Custom Web Pages in the EGX300?

Thanks in advance!

[JamesJeanette]

Thanks Laurent.  One correction...Com'X 510 will be available in Q1 2015.  There is an ongoing project which will enable VPN through the Com'X product line.  More to come on that later.

The article is no longer there. Any idea what is the new link?

Hi Jos.  Here is a direct link to the Custom Device Type Generator document in SEC:

Let us know if you have any questions.

Thanks!
