I am trying to connect to a TOC-8 and I am getting a no response error from IQAN Develop.

The Green LED is on. There are no Orange/Red LED's on.

I am using a Prolific USB-to-Serial port communication cable.

All connections seem right.

My Com-port info is pasted below.

Not sure what I am doing wrong.

Could it be the com speed?

Hi People

I'm only relatively new to IQAN Design and am stuck and need help.

In a design I'm working initially without a display I was using a Digital Digital Compare function to test that a Joystick was centered and that the mode of operation for the joystick wasn't changed while the Joystick was anything but centered. The DDC function worked absolutely fine including detecting JS being uncentered at startup and preventing machine motion until it was released.

I added a display and the DDC caused an error message to appear on a display whenever in simulation I did something like start the system with the JS uncentered. I looked for a switch in the DDC functions properties where I could switch off the creation of the display error but couldn't find one. I don't want the error displaying because I believe that building the error handling means that the issue is no longer a system error which Ive handled with a separate on screen pop up message that says something like " center Joystick to re-enable motion" which is far more user friendly than the default error message the system puts up on a display.

So I built my own equivalent of DDC using "latching OR" functionality which does everything I want but unfortunately doesn't detect the 1 bad instance of a JS being uncentered at startup time, thereafter its does detect it being uncentered when an operating mode change is made that would be unsafe to do without the JS being centered before allowing motion to occur.

So my question is, is there a function or variable that is exposed to us and available in QCode or as a function object that is TRUE while in startup and False when not. In Ladder Logic for PLC there is usually a Data register or Coil that is true for the first loop of the code and false thereafter.

Alternatively if I was to set a digital parameter as default True and then programmatically set it as false after the first time a JS centered is detected and could then use that as an additional latched OR input into my safety function. However I don't seem to be able to programmatically change the value of a digital parameter in QCode and the manual defines the use of variables, even if named the same as an existing channel to be then treated within the QCode as a separate Local variable with the same ...confusing...name as the existing channel. Having read that the QCode editor advise "Hint at Position 5: Expression unused" that the defined variable is unused now makes sense.

I hope that's clear:-

In Summary:-

1) Can I turn off the error message on the display for when a specific compare function fails the comparison, especially if I'm not comparing physical inputs like voltage or current that would suggest a hardware failure, for which the resulting error message is entirely appropriate. Not looking to turn of all error mesasages, just those associated with specific compare instances

2) Is there a system parameter or function I can test that shows whether the system is in startup or moved to steady state?

3) Can I use Qcode to change the stored values of digital parameters DP or Function Parameter Channels FP

Happy for any advice you can provide

WHEN FLASHING MY MC 42 IM HAVING A HARD TIME CONNECTING PROBABLY DUE TO A 24V SHORT ON INPUT BUT ITS RESULTING IN THE OQAN MC42 HAVE A HARD TIME CONNECTING TO VIEW EVEN IF SUCCEEDED WITH THE SOFTWARE FLASH. I SPOKE W A PARKER SPECIALIST AND ITS ALSO SOMETHING NEW THAT HE HAVE SEEN .

ANY IDEA ON HOW IS THAT POSSIBLE IF AN INPUT ARE SHORTED WE LOSE THE MAIN CONTROLLER?

HELP PLEASE.

BEST REGARDS,

CS

I received popup on display unit after 77 hours 

Cycle utilization high alarm MD4-5

What is this related exactly?

I didn't found any info regarding to this.

Thanks

Health At All How can I control a car relay with HS digital outputs, without having the circuit error interrupted with a MC43?

Good day. I have a problem with the IQAN-MG module, my whole machine is not running now, I don't know where to get another one ... The problem will be fixed ... Can anyone advise, do you have anyone? thank you very much

I have number of MD4-10 displays with cracked touch screen panels. Does anybody know where I could get touch panel replacements?

Hi, what is the CAN name for an MC43 module. If it is unique to a series please provide for MD4 as well

Hello,

Got few errors (related to different sensors, Can bus,...) with that blue background behind

Any idea what the background could mean? crash of the display?

usually the errors pop up but the normal/working screen is always at the background, I have not seen that shutdown message behind before

Apart from changes internally meaning its no longer compatible with 5.05 or before, is there any other changes with the newer design? We use CAN communication rather than ethernet, is this still available to download and communicate with the display using design and run? Any other performance changes? I may be missing the post stating a new display has been released listing the differences!

I'm assuming nothing major has changed as there is still only one 5 inch screen in IQAN Design.
