with XA2/XS2 as legacy models in IQANdesign 6 and 7 would we be able to have added legacy support for the XC10 to allow software support. this would help with avoiding rewriting software from newer versions to IQANDesign 5 as units get redesigned to phase out outdated controllers. Additionally with the release of the MD5 what would the legacy support of the MD4 when it is eventually phased out. 

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. 

Hello,

Is there a way to list all active alarms? I am looking for a mechanism to list all active alarms after the dialog boxes have been closed and for a easy way to determine if there is an active alarm after a dialog has been closed.

The Active Error Level SIC channel will only have a value of 1 (alarm) or 2 (error) if the alarms are NOT acknowledged. Once the dialog is closed the channel's value returns to 0 even if the alarm/error is still active. I like to use this status to turn on a lamp on the dash if any alarms/errors are present even if the dialogs have been closed and then provide the operator with a place to go to to look at all active alarms when that lamp is turned on.

Perhaps having the ability to connect the Reactivation property for System Dialog Boxes to a channel could be a means to force all the alarm popup to be displayed again by changing the time to 1s when the user presses a button, otherwise set it to some large value.

Thank you 

It would be nice if a display page could be used as a channel somehow. Say I want to disable something while on page 1, if I then reorder the pages it is no longer linked to the correct page. Also, a component navigator link from the SIC active display page to the pages would be helpful to trace functions that would be affected by changes to page order.

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 !
