Max bus length

Kevin 4 weeks ago in Master modules updated by Gustav Widén (System support) 3 days ago 1

What's the realistic max bus length of master and diagnostics? I have an application that requires 2 masters at approx 100m apart from one another. Can these have master and diagnostic bus at this length?

I recall seeing in the IQAN instruction manual 40m is the recommended but maximum is 100m. Is this length take into account the 40 twists per meter, as 40 twists per meter at 100m length between modules would mean cabling of in excess of 100m actual cable length? If IQAN bus works at 250kbs, does this follow standard bus protocols and have a theoretical max of 250m @ 250kbs?

Will the soon to be added HS busses help any limitation?

I can always add an additional node to act as a midpoint transferring the data from one bus to another, effectively reducing the max length of a master bus to 50m, however it would need a diagnostics bus shared between all the master modules, which would be the maximum distance of 100m, and therefore the limitation?

Would CAN routing help me here with a central node that just runs its own independent program and routes the diagnostic bus and master bus through, and therefore has its own application file separate from the main 2 node application file?

MC4x/XC4x 12V 30W solenoid overload error

Dániel Novák 1 month ago in Master modules / MC4x updated by Gustav Widén (System support) 2 days ago 3

What is the suggested solution for driving NG6 valves with standard 30W solenoids at 12V system voltage with MC4x/XC4x modules? 


We use the HS+LS digital outputs for driving Parker D1VW valves with "K" code solenoids in a 12V system. As stated in the instrucion book, max load per output is 2.5A, but the measured current is 2.7A (as in the D1VW catalogue). The measured solenoid resistance is 5 Ohm, but it should be within 7-14 Ohm (MC4x/XC4x instrucion book). 

30W solenoids are standard at other valve suppliers too, so changing the valve isn't an option. Change the system voltage to 24V also isn't possible for this project.

MC2 constant red status LED

Adrien Léauté 2 months ago in Master modules / MC2 updated by Gustav Widén (System support) 2 months ago 1

Hello,

got a constant red LED on the status light from a MC2 and "no contact" and IQAN MD3 screen

that constant light is not explain in the book, i would guess an internal crash, could you confirm?

Is MC2 module replacable by MC2-M14 ? any software update needed ?

Thanks in advance

MC41 - M18-4 Barrel Speed sensor

Jose Solorio 3 months ago in Master modules / MC4x updated 3 months ago 3

Hi,

I have an MC41 module and I want to pick up the signal from a speed sensor M18-4VPFF200-Q8.

I want to measure the speed on the coupling between a motor and a torquemeter. I have a reflective sticker on the coupling, and I’m using this sensor to pick up the speed. However, when I connect the sensor, I’m reading zero on the MC41. I can see the lights on the sensor changing, which indicates the sensor is generating pulses, but the MC41 isn’t registering them.

Here’s how I connected the sensor:
Sensor pin 1 (brown): 12V
Sensor pin 2 (white): GND
Sensor pin 3 (blue): C1:12 on the MC41
Sensor pin 4 (black): C1:11 on the MC41

The max speed I want to measure on the coupling is 200RPM. I calculated the max frequency as:

Thus I calculated my Max Frequency (Hz) = (Max RPM×Pulses per Revolution)/60 = (200*1)/60 = 3.33 ~ 3 Hz

Do you have any input on whether the issue might be software or hardware related?

Thanks!

Master / Expansion Different -Batt

Kevin 3 months ago in Master modules / MC4x updated by Gustav Widén (System support) 2 months ago 2

We have a requirement to have multiple XC43 modules remotely to the master MC43FS module. Its likely they will all be powered from separate power supplies and they wont supply the same 0V for batt -ve.

Is this likely to be a problem in terms of interference etc?

Stylus for MD5

Kevin 4 months ago in Master modules / MD5 updated by Gustav Widén (System support) 4 months ago 1

Our customer has requested a stylus for interacting with the MD5 we have supplied. Instruction manual states a passive stylus for the MD5, has anyone got any recommendations or experience as to what works best?

MD5 Mounting Clips

Lars Bolduc 4 months ago in Master modules / MD5 updated 3 months ago 5

Parker # 20085209.

Anyone else receive 3D printed clips?

Surely injection moulded would be the way to go here.

Water will soak into the porous material and the clips will fail?

PWM Output Commanded to 0, but voltage measured at Output

BFSENGR 4 months ago in Master modules / MC4x updated by Gustav Widén (System support) 4 months ago 3

IQAN Tech Support,

We are looking for help with troubleshooting our "IQAN Controller, Master Unit, IQAN - MC43" Safety Controller. It is getting inputs from two Temposonics tank-level sensors in our electronic water-level system, models GB Series & RF 5th Gen input sensors. The IQAN controller is PN 20085113.

We are receiving a potential difference (voltage output) of 0.39 V from Output pin to System Ground when measured with a multimeter; however the programming software indicates that the output should be 0 V. Our known inputs and outputs are below:

Inputs

Outputs

I!: Inclinometer 

    Connector 1, Pin 26

    0 – 5 V

    O1: High

      Connector 1, Pin 48

      0.24 V (Pin-to-Pin)

      I2: AFT Level Sensor

        Connector 1, Pin 53

        4 - 20mA

        O2: Low

          System Ground

          I3: FWD Level Sensor

            Connector 2, Pin 33

            4 - 20mA

            ***SHOULD BE = 0.0 V Output***

              • The tank level sensors are bottomed-out, as there is no water in the tank.
              • With no water in the tank, the IQAN is programmed to output 0% Du Cycle, yielding 0.0 gallons on the display - but there is a .39V measured.
              • The lowest water level reading that the sensors could output is 120 gallons, but should read 0.0 gallons below that.
              • We are needing help troubleshooting and establishing / calibrating our 0.0 baseline

              Questions: 

              1. Why is a voltage being read at the output, when the program is indicating that it should be zero? 

              2. Can we create a code or loop in the program to circumvent the small output voltage?

              Slow cycle time on MD5

              Brian Penzotti 5 months ago in Master modules / MD5 updated by Gustav Widén (System support) 4 months ago 1

              It appears the fastest application cycle time on the MD5 currently is 50ms, which is 5x what it was on the MD4. Is this something that is planned to be improved in a future software or firmware release?

              I need to be able to send out 10ms messages and it is just not possible from what I can tell on the the MD5 series.

              Larger Program memory

              For a long time we have been running into the limitation that the Program memory is too small for us. Is there also a view with the new MC4x to increase this in the future to 3Mb for example, this would help us enormously in adding functions that we are now forced to leave on the shelf.
