Programming/upgrading controllers require security login
We got a question from our service guys that when they upgrade a program on a system to the latest revision that this particular version is asking for one of the usernames and passwords from the security section. Not the limited or full password but a user one.
The only thing I can think would cause this is I added an adjust item in this latest revision that requires the user login from above. Could programming a previously programmed system that DIDN'T have said adjust item(requires user login to change) to a version that now has said adjust item cause the individual programming the truck with IQANrun need to login with a security user/pw ?

MD3/MC42 multi master trouble
Hi everyone.
I have encountered a strange problem with a MD3/MC42 multi master system and cant't seem to resolve it "quickly".
The problem is that I cannot upload the software onto the system effectively. I have used MD3's and MC42's quite a lot in the past but never together like in this manner and this is the 1st time I encounter this issue (usually I have a MD3 with an expansion module or either a MC42 with a MD4 multi master system with no problems) so this time we wanted to use the MD3 and MC42 together for a project, so I thought it will be basically similar to using a MD4 with a MC42.
I have a 0T id tag on the MD3 and a 1T tag on the MC42, when trying to uplod the software via USB through the MD3 I get the message "incomplete system" and showing only the MD3(Safe mode). But the display also indicated wrong ID tag for some reason.
Then when disconnecting the 0T ID tag from the MD3 and try to upload the software, it works when I click yes after I get this message shown below, both controller get updated though, but then after uploading/startup a message appears on the display stating "CONTROLLER MC42 : NO CONTACT"
Does anyone have an idea what I am doing wrong and where? Am I reading the MD3 manual wrong or something? It states when using it in a single master system no ID tag is required (only a tag on the expansion module if present) but using a multi master system an id tag is required.
I have tested this on 2 different wiring looms also with other new controller modules, all with the same result.
What am I missing here...?

MD4 Crash With Blue Screen
I have a customer with a machine fitted with multimaster 1 x MD4 and 2 x MC3 running 3.19.10 (display is running 3.19.10.910, MC3 running 3.19.9.2170). Randomly with the machine powered and no change of inputs on any modules or touch inputs to the MD4 we get blue screen. The display does not recover from blue screen, and the system needs reboot to clear the error.
Logs in MC3 (number 1) suggest loss of contact with MD4 display and second MC3, no contact. At time of MD4 blue screen i got a diagnostics bus error (wired to bus D on each controller) logged only on first MC3. Second MC3 does not appear to have any no contact errors with any modules. MD4 does not appear to have any no contact errors (dosnt even log the blue screen).
I see there are some old issues found with the V3 software, would the recommendation be to update to version 4.03 initially? We have 10 machines running his software successfully, only this machine appears to be troublesome, they are all running same software and hardware.
We have CAN open device on CAN C, terminated both in display using software termination and also at the node end using resistor.

Password protected actions?
Using a MD3 I have a set of "Emergency Functions" to give direct control over the system and bypassing the normal safety over-rides. I did this to allow a malfunctioning truck to return to a safe condition so it can be brought back for servicing and allow for easier servicing.
It function by using various screens and jumping between screens to control different circuits.
I currently have it so you put in the password once to enable these functions by allowing access to these screens, and then they are enabled indefinately.
What I would like to acomplish would be
A. Require a passeword input every time the main emergency function screen is accessed,
or
B. Have the State Parameter that is adjusted to allow the Emergency Functions to be accessed, reset to "disable" with every power down.
I don't think I can do A, but it would be prefered. B should be doable, but I don't see quite how to do it. Do I need to use something other than a state parameter?

Array does not store value
Hello everyone,
I have some issues with arrays which don't store the value.
I use a digital trigger to store some data in 6 different arrays. 2 of them correctly store the data so I can get them after, but the 4 others don't store the values, they stay at 0. Stored values are real.
Here is the Qcode i use to store the values. Expect the name of the channel, it is the same Qcode for each array :
Thanks in advance for your ideas about this issue.

Issue with the radio control expansion module (XR) in IQAN Design 5 software update 5.03.14.5040
Hi,
We have noticed an issue with our systems that have a radio expansion module (XR) in the IQAN Design 5 software update 5.03.14.5040. The master module in our system can no longer connect to the radio system when a program in software version 5.03.14.5040 is downloaded to it. However with the same system and same program our master module can now connect perfectly to the radio system but with the program at software version 5.02.13.4984. We noticed this issue as soon as we updated our IQAN design 5. We have created a simple program In IQAN Design 5 with only a MD4-5 master module connected to the radio expansion module (XR) to show visually what we mean. The radio system we are using is a Hetronic radio system. Please refer to the images below. Has anyone seen this before? is this a known issue? or are we missing something? Thanks a lot for your help.

Does this combination still support the serial port functionality to interface with GSM modems ?

MD3 unusual failure
Hi everyone,
I work with a customer that uses system with MD3 to control forklift truck.It has worked well for quite long time and suddenly MD3 screen has gone blank (black) however all controls work fine (system works fine). Have you got any suggestions where to start trouble shooting.
Thanks in advance for your valuable support
Regards,
Richard

You probably have a too high module temperature.
If i remember well, the backlight is switched off when the internal temperature exceeds a certain limit.
When the temp goes down, the backlight should be activated automatically
Maybe you can measure the temp with iqan run

Generic parameter out : Wrong value sent ?
Hello,
I have a problem with some generic parameter out. I am sending values to a radio controller display, to be displayed. Value in the IQAN program is 2 for my three parameters, I send then with a generic frame out. Problem is that values displayed on the radio controller are respectively 0, 103 and 26112 even if my 3 values are equals to 2.
I tried to change the different parameters (signed/unsigned interger, little/big endian) with no changes.
The radio display is programmed in Codesys, and the manufacturer suggest me a SHL shift on the values. I don' know how I can check that and change it if it is the problem. I have the Codesys program but I don't really know how it is structured or to re-program it.
Can you please help me with that ?
Thanks in advance,
