Hi!

I want to put a IQAN MC42 to control crane on a timber truck that previously had Olsbergs CAN joystick controls.

I remember that older Olsbergs joysticks were tuned to use 165Hz PWM.

Maybe somone here has experience and is willing to share a correct PWM frequency to control Olsbergs valves with MC42 module COUT?

Maybe you have some tips on things to watch out for?

Thanks in advance.

Hello,

simple question. Is there a way to align channels in IQAN Design Code? For readability reasons.

I can't find the function and my colleagues have no idea either.

Feature highlights

Multi-line support for messages

CMSG and IMSG channels now support multi-line on Text and Help properties.

The message box indicate with arrows that one can scroll up/down.

RAM memory optimization

Memory usage for Qcode is optimized.

RAM usage has also been decreased for IDC channels not using toggle, delay on/off or function selector.

Possible to select 1 Mbps as J1939 bus speed

J1939 is normally 250 or 500 kpbs. For proprietary buses based on J1939 it is now possible to also use 1 Mbps.

Set default width on new channels
Added default channel and function group width to options dialog.

Good Afternoon,

I am rather new to IQAN Design and need some assistance. I am using a looking to run an L90 valve with an MC43 and for one of the functions in a dual direction math channel I would like to switch the value from negative to positive and vice versa for the positive value. In essence the direction of the valve needs to change from the direction of the joystick.

Anyone out there have an easy way of doing this?

Thank you.

Hi!
I would like to use a channel to reactivate error messages. This can now be done every x seconds, but I'd like a button for it. 

I commonly use position data in my functions and some behaviors require precision latitude/longitude (4-Byte, 10^-7 resolution). This is an issue due to the limitations of floating points in IQAN. I have come up with a solution to this problem. 

Most behaviors require 2 positions (vehicle position and desired waypoint). so you will have 2 sets of Lat and Long to deal with.

First you must keep the 4 bytes of each value split into 2 byte chunks until they are processed into relative position (a function in the below file). once the position is in relative space, the value is small enough to avoid any precision loss in the floating point form. you can change the inputs to make the origin either the vehicle or the waypoint.

The next issue is displaying real Lat/Long values (Not relative). The second function in the file is used to display 32 bit values that are split into 2 byte chunks. Without going into too much detail, it calculates each individual place separately and concatenated them in a text formatting function. 

I'm sure that i am not the only one who may need these functions. I hope this helps anyone that may need them.

CAN bus latched failure status doesn't allow normal working before eather a software reflashing or a power reset. It's just unacceptable that the device crash and there is no way to reset it softwarely or even have this feature build-in in the low level firmware layers. Every other components can achive that "return to normal state" when the fault disappears. 

We tested it today by shorting can bus conductors together. We where expecting that disabling and re-enabling components would get them "back to life" for the Parker IQAN system. Finally not, the bus error stays (bus-off), other components of the system (Motors, battery and controllers) get back to normal state and keep "talking" despite IQAN MC43-FS device is still flagging "Timout" on their Can messages and "No Contact" on Can its message outputs.

It's major ! With actual safety related involvment ! 

By chance, that time it happened on a charging infrastructure so while the vehicle where immobilized, but what could we do if an error occures while the vehicle is circulating on the highway ?! It's just not acceptable to permanently lose power (by controlling a drivetrain) while the error / fault is gone. It must have a way to reset the bus !

Thanks for following-up !

Simplified IQANdesign renewal

The IQAN store “IQANdesign update subscription” is being replaced with a new option, IQANdesign license renewal.

Renewal gives the option to use your latest license number to purchase a new IQANdesign license (80% off), valid for updating to all IQANdesign versions released within 12 more months. 

This is the same price as the previous subscription, but without the need to sign up beforehand and having emails from the store with reminders.

Manage license in IQANdesign

Two new release versions of IQANdesign are now available:

IQANdesign 6.08.25 and IQANdesign 5.08.2

In these versions, there is a new menu item:

Help > Manage License

Manage License lets you view the full license number and enter a new one. If the current license is too old to install the latest updates, a link to IQAN store for IQANdesign license renewal is shown:

Hello,

Inside the IQAN software there`s the check for updates option in the HELP menu. Our company has installed a new firewall and now updates are blocked. Can You tell me the serveraddress / port I have to whitelist to get these updates going again?

Thanks in advance,

André van der Heide

I have a couple of small requests to make usage easier.

When doubleclicking for example in a name field with two words it selects the 1 word you clicked on.

In other Windows programs or in this forum for example, triple clicking selects all words in the field/row, that would be handy to have in IQANdesign aswell. Especially when creating new channels with long default names like "Dual Direction Math" or when creating many states/text parameters for engine fault codes.

When clicking on a state function the last selected tab/state is shown, the name does not have a box around it so you can edit the state function name.

If you click on a state name then it gets a small gray box around it and you can edit it's name.

If you create a new state the name does have the small gray box around it, but if you type in a new name you will edit the name of the entire state function, this is opposite to the behaviour above.
