Hi,

I was looking for a vibration sensor to use with MC41.

I have got the Parker's ACC50 accelerometer as this is advertised as vibration sensor among others.

It has an output 0-5V and measures G  (+-1.5G 1-axis). 

Although, I would like to measure frequency and amplitude as well.

Is it possible to use that sensor and convert the data to frequency live or later?

If no, is there any vibration sensor that can output frequency / amplitude?

Thank you.

Hi,

I am new to iqan and I work on a project where I have connected an arduino uno with several sensors on an MC41 / MD3 via generic can bus.

I have managed to transfer correct values for most of the sensors up to number 255 (1byte). i.e temperature, humidity, sound do not need more than 255.

Although, I use an accelerometer /gyroscope where it can go up to +-2000 dps (degrees per second). As I mentioned before I can get correct values up to+-128 dps. 

As a solution I tried to send 2 bytes for the gyro and read 2 bytes in iqan as well. That just changed the scale. i.e -2 dps became -512 dps. Also, I played with less bits in iqan but still the same. I get correct numbers only when using 8bits. 

Is there any way to split the bytes in iqan and read the correct value more than 255?

Any other idea to solve this would be helpful.

Thank you. 

These are the memory specifications of my system, when I try to send the project to my HMI, it goes into safe mode with the following message Out of memory, could anyone help me to solve this problem, 

thank you

We have tried accessing a machine remotely and have the following message, is this a problem a Parker end? We have tried 2 PC's and have the same message.

Hello, 

Does IQANdesign support devices which communicate using the LIN protocol?

The aim is to use this device for standard parameters such as voltage, current and charge.  

An example to illustrate this would be useful. 

Thank you

Sometimes (due to our own fault) we forget to check the system is either connected to the computer properly or ignition is switched on. Our projects typically take a good 5-10s to check, then when clicking send it errors saying system not connected, forcing us to re-select send project and go through the project check again. It does not sound like much time, but can sometimes be frustrating waiting for it top check again.

Is there a way of alerting you (after selecting send command) that the system is not connected so it doesn't close project check and force you to have to resend, then check the project again? Just an idea, other people may also find this useful.

In a new controller we tried to load a program, but did not succeed completely. Then the LED of the controller blinks 4 times red and 1 time yellow followed by 17 times yellow. And when we try again to connect, the master module can no longer be found. Is there something we can do?

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

Hi,

I have integrated the backup camera on our vehicle and I came across a lag issue with the camera and was wondering what the root cause was. Please see attached video (https://www.dropbox.com/s/0wgs5htr8moqyss/IMG_4580.MOV?dl=0) . Maybe you guys could help.

I chose to go with a 50 ft M12 cable, and there is not much loose considering the fact that the box is 20 ft long.

( https://www.digikey.ca/products/en?keywords=wm15300-nd). 

I played with the following parameters in IQAN for the SV Camera

• Enable HDR: No
• Max bitrate [mbps] : Toggled between 1 and 20. At 1, the image is really pixelized as on the attached photo. At 20, there is a lot of lag. The current setting is at 4, and the image quality is really poor with some lag. Considering the fact that this camera will be used to backup to a shipping dock, the small lag is a big concern for our customers.
• Dimensions: I toggled between Wide 800x600and Narrow 160x120 with no interesting improvement.

Is there something here that I am missing? My though is that the wire is too long, but it is impossible for me to shorten it.

Best regards,

Is it possible to limit an Event counter channel with a maximum and a minimum value?
