With the new MC42 and MC43 master modules, I see you have the ability to communicate via Ethernet communication port. Where can I find this part?

Hi

It will be possible use MC41 IQAN module as a slave?

How use MC41 and Panel MD3 together in same project?

Does the current consumption of the module (170mA @ 24V) increase if we start connecting sensors on the VREF pins or does this value include the max draw on both the VREF (140mA x 2)?

Does this apply to all master / expansion modules?

Is there a way of detecting how much current draw there is on the VREF supply on an MC3?

I have experimented with a SIL2 pressure transducer connected to an MD4 (don't have an MC3 to hand) and noticed that disconnecting the -VREF and leaving +5V supply and VIN signal wires connected to the controller will generate 2500mV signal into the MD4 VIN. This is not desirable as it simulates a pressure in the system which is not true. I can only imagine its how the internal electronic circuit is manufactured inside the transducer causing the false signal, but its not unique to one manufacture of pressure transducer. The current consumption of the sensor drops from 6mA to zero when the -VE is removed, wondered if this would be a good way to detect disconnected -VREF connection?

Aside from the method above or monitoring for a sudden change in VIN signal within the software, can anyone suggest any other solution to this issue?

One of our field units is getting the an "Error" on start-up. It occurs on every startup.

After the error is cleared, everything is working fine. The solenoid(s) showing the error function with no issue.

In the past we have seen open load and overload output errors but not just a generic error message. We replaced the MC3 module and the problem was resolved.

Just curious on what this means? Thanks

Hello,

I have a drill rig (Geoprobe 6712DT) which has an MC3 Module installed. Recently, the hydraulic pump would intermittently would stop building operating pressure, and the only workaround I can find is to bypass the MC3 Module and manually force the pump to build pressure. The Module is giving me a 1:2 error code, or "Input" error. Could someone help elaborate what this error could mean in the general sense? Any info would probably help with my troubleshooting. I'm guessing it could be something as simple as a loose wire, but I can't seem to find any so far.

The drill rig comes with the MC3 Module installed, and has worked fine up until recently. The manufacturer doesn't really provide any troubleshooting in regards to said module, so I'm kind of just winging it. The manual for the module tells me that it is an Input Error, but I'm not really sure what could be causing that.

Thanks in advance for anyone who can help me out. My apologies for being somewhat ignorant as to this thing... I'm just a humble driller.

A 5 year old MDL2 is giving us this exact (system) pop-up message:

"

Log error

Failed writing. The log has been stopped!

"

My guess is that the (flash?) memory is full or corrupted, so system events like a startup or sensor error can't be written anymore. Not a big deal, but:

* How to get rid of the message

* In case the log memory is corrupt, would that also threaten other memories? In other words, should we replace this MDL2?

As far as I can see, this a fixed system message, not a custom pop-up.

I am using an MD4-7 screen on a test bench. 3 out of 4 starts I get either a White Screen or a black screens with some colored dots. Once I saw what seemed to be blocks of black and white.

Looks like the video driver is not starting properly. The application appear to be running since the canbus messages are being generated.

Can this be caused by the regulated switching power supply during start-up or do I have a defective MD4 screen?

Thanks for your inputs.

Is there any plan to introduce Ethernet port to other master modules than MD4? It is quite a good feature in my opinion,

Our company uses an IQAN MDL2 setup which ties into the J1939 network of a Caterpillar system.

Our setup is using the internal resistor on the MDL as the terminating resistor on one end of the network and has a standard 120 Ohm resistor wired into the other end.

A machine in the field is having CAN network issues. Typically I am used to checking the resistance of the CAN network and the resistance of the terminating resistors as a standard checkout of the wiring. However with the internal resistor this is proving difficult.

In our lab I powered up a test MDL2 and checked resistance at the MDL with the MDL powered up but no other wiring attached. I found that I would measure ~69 Ohms across the internal resistor at first power up. If I shorted the CAN Hi and CAN Lo together by touching together my multimeter probes it would cause a CAN C "CRITICAL ERROR". After this error I would measure ~115 Ohms across the resistor until the power was cycled on the MDL.

All this said, my questions are:

-Do you have any recommendations for a standard procedure for troubleshooting CAN wiring/resistance?

-In light of the testing I did in our lab could you provide an explanation on how the internal terminating resistor on these IQANs work?

Thanks
