Can someone explain to me why it is important to have a superuser password?

Do I still need it even if I already have a full access password and limited password?

thank you

Information for the different IQAN trainings can now be found in the "Links" on the main page.

Hello,

We have a crane control application on MD4-5 and occasionally this message pops up and the whole system is paralyzed and you don't have access to any menu, until restarting the system. 

What is that external system?

Is there any way to label the list of static IP addresses with a user defined machine ID rather than the IP address?

When I enter an IP address (e.g. 10.1.1.1 ) into the static modules list, it's machine ID is listed as the 10.1.1.1. But is there a way for me to change that to e.g. MACHINE 101? So I don't have to refer to a separate list I have created which translates the IP address to a machine ID that I am familiar with?

Hey

I have a couple of channels in a project that tell me there is an implicit value conversion occurring. What I'm confused about is exactly what it means and why its a warning?

In the Qcode below:-

HydOilLowNCorNO is a digital parameter that determines whether the input condition is NC or NO which translates to if a logic 1 is good or bad.

MaintBypassSensorHydOilLow is a digital parameter that determines whether we should action the sensor inputs or simply ignore them. iI's used here in this channel and in an almost duplicate of the channel that deals with digital input HydOilLevelVeryLow which is the last switched step on the tank level sensor and which triggers an immediate idle down, and timed shutdown of engine 

The Qcode is:-

TempResult:=0
If HydOilLowNCorNO Then TempResult:=Not(HydOilLevelLow) else TempResult:=HydOilLevelLow
If MaintBypassSensorHydOilLow then TempResult:=0
Result:=TempResult

The warning I get is that the bolded underline is an implicit value type conversion. What I struggle to understand is what is being converted? everything except the local variable TempResult is digital including the channel type IDC. There as far as I know is no way to declare a variable as specifically type digital and if I change line 1 to TempResult:=False then I get another implicit value type conversion warning for that line.

I know a warning isn't the end of the world but what do I need to do to get rid of the warning or produce better code? Is there a way to declare the local variable TempResult as type digital that Im simply not aware of?

Warnings in IQAN Design  to me infer something is suboptimal but here I cant see what I should do to change that.

Hi

I have a remote machine that has a teltonika modem on it that I can access remotely using OpenVPN. I know the configuration of the VPN is good because I can access the Teltonika admin pages (192.168.10.1) without issue from my laptop connected to my phone hotspot on 192.168.111.100

In the Teltonika  admin pages I can see that the modem has allocated a DHCP address to the MD4-10 module and I can ping it and successfully get responses from the display.

In Design I can see the MD4-10 module in the discovered modules but its discovered with an IP address of 172.16.0.1 which is the VPN endpoint assigned to the openVPN tunnel at the modem end. Ive added a static module with the right IP address of 192.168.10.14, but unlike the discovered module the indicator light never turns green.

Any attempt to communicate with the module fails with a "failed to open a new communication session" error.

Has anyone dealt with this issue before and sorted a way through it, I'm trying to work out if this behaviour is due to a missconfiguration of my vpn, or if its by design because I know Parker have a solution exactly in this space. If my understanding is correct though its a 3G based solution where Australian Telco's have all announced end of life for 3G in comming nearterm months so not a particularly long life solution.....

help if you can

Hey Everyone

I have a sensor I need to try and source and its not proving easy to find.... I'm working on a 50T Horizontal tree mulching machine. With any machine of this size which has a large rapidly spinning mill vibration can be an issue. If the mill is balanced then the vibration is minor and if it's been damaged or worn out of balance then the vibration can be extreme and destructive.

We have a working solution for balancing these types of Mills that can be called on when needed, but I'm looking to permanently establish a sensor on each of the mill bearings that provides over canbus a single axis vibration reading from which at startup prior to introducing tree material we can determine if the mill is go/nogo. For a balance you need a vibration quantum and an angular measure of unbalance. To determine what I need I really only need the vibration quantum and wouldn't expect to put in an optical sensor from which to measure any angular unbalance from. 'm hoping that there are suitable sensors available that can tell me over J1939 or CanOpen that the vibration is x IPS^2 (or any of the other multitude of measurements that can apply to vibration....my background is aviation hence IPS) 

Anyone seen anything like this?

There are heaps of accelerometers that can provide me with sinusoidal waveforms but that means I have to put in hardware to size the waveform appropriate for the controllers and then make my IQAN controllers interpret the waveform when they are all busy anyway, something I can hopefully offload to a sensor

Looking for approx 10 IQAN-XT2's for a project (a retrofit).

Hi.

Do you have any experiences / recommendations for Iqan CANbus -> mqtt gateways?
