I am trying to send SDOs to a CANopen signal converter. Manufacturer has given me a script to follow but not sure how I would integrate this using the generic CAN frame-in/out channels. Any help is appreciated, thanks.

Manual for the converter:

Hello,

I'm pretty confused about something.

Right now I have a single 4 Byte JPIN with a dedicated JFIN.

Standard 1 resolution per bit with no offset.

And I'm displaying it with an unlimited Value Control with automatic width.

32 bits should go up to 4,294,967,295 (0xFFFFFFFF).

The highest I can slide the slider in IQANsimulate is 2,115,669,120 (0x7E1A8C80).

And the highest that will be displayed in the Value Control is 2,000,000,000 (0x77359400).

Is this a limitation of the simulator, and it'll work fine on the machine?

Or is it a real limitation of the JFIN/JPIN?

Regards,

Hello,

I am using a MC43 to try and drive some hobbyist 9-gram servos for a project. We are using a unidirectional, HS-only PWM_OUT channel to try and move the servo with a signal of 1100-1900 us. We have tried to setup several resistor networks and logic level converters to get the 12V signal from the MC43 to the 5V threshold for the servos. However none of them have worked. Additionally, we are also noticing that the signal from the MC43 only goes between +5V and +12V when a pull down resistor is applied between the signal and ground.

First time using CANopen and we are trying to set up the parameters for an Axiomatic CAN controller to send analog outputs. Took a look at some examples on IQAN and going through the EDS file but still a bit lost on where to start. Looking for any insight from those who have experience configuring this type of device. Thanks!

Hi!

Scenario: An urgent project can be made with MC42, but I only have MC43 in stock. I send it to a customer with MC43 module, so he can start working. When I receive a MC42 module, I adjust the software to a MC42, load it in the module, send it to customer and he plugs it in, and sends me back MC43 later.

Question: If the customer has adjusted currents how he prefers on MC42 and saved settings via Bluetoth connection and IQANgo will he be able to load those settings back in when I send him MC43 with same project insde? Or will he have to readjust everyhing again?

I'm adding a Axiomatic RTC controller with J-1939 to a legacy machine. When I revise the IQAN 6 software, can both the RTC and TDA be enabled at the same time without errors? If RTC and TDA are enabled and the external TDA (External RTC controller) is not present, will the MD4 default back to the internal RTC?

When I am using the parameters menu to adjust any of my integer parameters, there is a Reset... option in the kebab menu, what is the intent of that function?   It seems to recall the stored/retained value from the beginning of the current power cycle, not the parameter's default value.

There is some reference to mode 0 in the resulting dialog box:

Notice I have had to manually add default value text descriptors since there is no clear mechanism to reset to factory defaults.

This is IQANdesign 6...8136, MD4-7, the behavior of the simulator and the device are consistent.

I have a system that wirelessly connects an XC21 to MD4 and occasionally it drops connection momentarily. The time the CAN is down is very brief, only ms and it reconnects and communicates again after the disruption.

Although the module reconnects, it leaves an error on screen that the operators have to clear. Is there any way of either extending the delay for displaying the message (assuming there is some damping built in the firmware) or clearing the message automatically, or perhaps even switching this message off? 

When adjusting the minimum output current of a COUT, IQANrun imposes a limitation on the COUT equal to the set minimum current.

If the controller drops the application, without a graceful disconnect, e.g. if you do not first disconnect IQANrun before you connect with IQANdesign, then the imposed limitation on the COUT remains. This can cause a lot of confusion if you are unaware of this functionality.

It would be preferable if a dropped connection immediately removes the current limitation on the COUT.

Being relatively new to Hydraulics and IQAN It seems to me that most experienced folk in that field talk pressures in terms of BAR and others who maybe more peripherally involved use PSI. In my world that means that teh engineers/mechanics/fitters etc use bar and machine operators tend to use psi. As such on most of my HMI designs I have a slider/switch/parameter that can toggle between the 2 so that who ever is using the machine can see their pressures in their measurement of choice.

The calculation between the 2 is not complicated, nor is the building of a structure that allows you to easily swap on the display the visible output between one unit type and the other.....but it gets old having to put multiples of those same building blocks in place to do the conversion and support the visible flag for multiple pressures etc and it makes HMI design a drag as you overlay mutiple gauges etc....

So I was wondering in the (sometime) future if the definition fields for a device like a pressure sensor (but in effect any device) could support multiple measures and either output in terms of a separate output channel for each measures or use an input channel to define which of these comes from a single channel output... For example an SP035 could have  definition 1 as min 0, max 35, unit bar (just as it is today in design) , and definition2 as min 0, max 507.7, unit psi, being effectively the same thing. The downstream math channel or internal digital that does the calculation/ manipulation could access the device choice channel to modify whatever is being done to account for the unit values differences

If the same input channel that determines which device definition output to use was also available to display devices we could also have multiple scales on a single gauges etc rather than multiple gauges that are selected by a visibility channel.

I know its late Friday afternoon as I post this and my brain may have exceeded its weekly whirring amount....Is this something people think could be useful or should I just shutdown for an afternoon beverage earlier in the day :<)
