i am getting system messages that say the xc22 module isn't found. then it powers up and works but messages doesn't go away. highly annoying for operators

Hello,

Where can we learn the capacity of the processor of the MC42-MC43 controllers, how much of it we use, and how much we need to use?

Hi, There are many function groups, I rewrote a function group. Can I run the other one without deleting that group? Or how can I deactivate that old function group?

Hello, does the Timer channel send data only in 50 mS? Can we reduce this? We want it to do it more frequently. How can we do this?

Wire kit 20085205 does not have C1:31 and C1:45 for an address tag even though it is shown on the pinout. Is there an internal selectable tag? Do I need to manually add these wires?

Hello,  

I have an MD4-7 that I'm working with.  On one of my screens I display GPS coordinates in decimal degrees and D.M.S.  Sensor is external NMEA2000 device. While working on this screen I noticed that my Minutes display of Longitude did not correlate with the decimal display.

I've verified the GPS position I'm using as a sample against two other GPS receivers so I know what the correct position should be to within a few meters.

The incoming decoded decimal portion of the longitude position is x.56, and when multiplied by 60 should give me Minutes of 33 and change.  The MD4 is displaying Minutes at 26

I've tried a couple different variants of the basic formula:

Result := (Longitude - floor(longitude)) * 60 

Variant uses integer value from int math channel to subtract the integer part of the number.

The Latitude calculation is giving what seem to be correct results at first glance (the number displayed is "more" correct in terms of actual position), however, 0.42 * 60 = 25.2.

Am I doing something wrong with the number types?  Is there some truncation/resolution issue in the background?

CALC - LON = raw decoded float value (NOT SHOWN)

CALC - LON-DEGREE-FLOAT (alternate math channel - troubleshooting)

CALC - LON-DEGREE (INT math channel - troubleshooting)

CALC - LON-MINUTES (longitude decimal minutes)

CALC - LON-SECONDS (longitude decimal seconds)

We have a situation where a PWM input occasionally drops to 0%, which is intentional and not indicative of a fault condition.
However, this triggers a low error message that we would prefer to suppress unless the condition persists for a defined duration, such as 10 seconds.

As discussed in other forum topics, one approach is to place the PWM input channel into a function group and enable or disable the function group to control the error message display. 

While this method can suppress the error message, it also disables the evaluation of the input channel, which is not suitable for our application.

Ideally we would like to:

• Suppress the low error message for transient drops below 2.5%.

• Display the error message only if the low condition persists for a specified duration (e.g., 10 seconds).

• Maintain continuous evaluation of the PWM input channel to ensure accurate monitoring.

Any help would be most appreciated

Hello,

I program machine with 7.04.8.10088.

But machine reports back 7.04.7.9978. (Via SIC Software version)

Simulator reports back 7.04.3.7033.

Which is the correct firmware?

With multi-master it is important we know the exact one to send to customers in the field.

Regards,

IQAN design takes a painfilly long time (5-30s) to load blocks (int, real, digital, arrays) that contain Qcode, seems to take longer, the longer the project is opened. Also the compile times vary a lot and can take insanely long to compile (20s-3min). The computer is modern and powerful (Intel(R) Core(TM) Ultra 9 288V, 32Gb DDR5 Ram, SSD etc., so it shouldn't be the issue. Is there anything I can do to improve this performance issue?

Hello - I'm trying to 'Get Project' from an older MD4-7 via Ethernet connection from PC to the display C3.  IQAN Design can see the display (listed in the subwindow), but when I try to proceed I get the error box: "Incomplete System" "Operation was aborted. The following modules were not found: MD4-7[1] (Optional)"
