Hello,

i have noticed, and now a customer has brought it to my attention, that his dashboard isnt showing connectivity status on the asset dashboard. this seems to be happening across multiple org pages. here is an example from one of mine:

Notice no online or offline status is showing. I know for a fact that this gateway is online as it is part of a demo at OTC.

Also, none of the assets (there are 2 in this org) are showing up on the fleet overview page:

I have informed my customer that this does not indicate whether or not the gateway is malfunctioning, but to me it simply seems to be a bug of some kind. I dont wish to tell my customer that there is a bug, but I dont really know what else to say. Their gateways are monitored on a daily basis to compile reports and any mishap is documented. These gateways for this customer were bought on a grant that requires them to report on energy savings, battery life length, etc and any service interruption (or appearance of such) is documented. They are of the opinion that the portal is not quite polished enough to warrant an increase in purchasing. 

What I need is a little help in understanding why things such as this occur, and any ways to optimize the portal experience so as to reduce instances of the aforementioned problems.
 

I have a few customers tat build equipment with the IQAN system as the main controller.  They are currently using the MD4 or MD4 as the head master and multiple XA2 modules as the slave units.  They want to use the MC43 modules to replace the XA2 modules so simplify the system, but when doing so, have had issues with making the MC43 modules as optional.  The XA2 modules were on specific attachments that were connected to the main system and then configured as being present and then thus enabled in the application.  If the XA2 needed to be replace, there was no need to worry about any software or firmware to be loaded onto teh XA2 module to get it to work in the application.

Now with all that being said, the MC43 modules used on the attachments present a problem if they were programmed with a different application or firmware when initially set up.  The OEM cannot simply send out a replacement MC43 reflashed with a base attachment application and have the end user plug it in and have it work.

HI All.I used XA2[1] for voltage and digital inputs for MD4,While testing I got "NO Contact" Error in RED color as I did not connect any expansion units.Can I give these input values directly to MD4 with CAN and without using Expansion unit XA2[1] connection?

Any plans for bigger MD4 displays, perhaps 17"?

Hello sir,

I am working with a Parker L 90 valve. The recommended PWM frequency is 100 to 125 hz. I wanted to understand the reason behind.Does this has anything to do with the Resistance/inductance of the coil ? Like the rise time of current in coil ?

If I run the coil with high PWM frequency say 2000 hz , will the current ever reach to maximum (I = V/R) ?

Is the recommendation of 100 hz only for avoiding switching losses or it has to do with performance as well .

Thanks

I need 8 directional pulse count inputs... Is there any hope other than using 4 XA2s? Any plans for an IQAN expansion module that can do 4 or even 8  of this kind of input?

I can't find any 3rd party CAN modules that have this type of input. It seems to be all industrial modules.
