Error "Configuration error I/O driver DN2DRV" when configuring Devicenet network device on (V)KRC2ed05.

Hello everyone, Hello experts.

I am currently getting the error "Configuration error I/O driver DN2DRV" when configuring the Devicenet network device on (V)KRC2ed05. Can everyone help me check the status and if my settings are correct and guide me to fix this error? Thank you very much everyone.

==>MY CONNECTED STATUS IS:

==> Receive feedback signal from the Automatic Knife Compare head (4 wires divided into 2 pairs of Normally Closed Wires (NC) Red - Black and Blue - White) through Digital Input Signal.
- Connect 2 Black and White wires in 2 pairs of NC wires to Pin G on Module DRT2-ID16-1.
- Connect 1 Red Wire to ID0 pin.
- Connect Blue Wire pin to ID1.

==>ERROR STATUS.
- MS (Module Status) light on Module DRT2-ID16-1 is Green.
- NS (Network Status) light on Module DRT2-ID16-1 is Green.
- MS (Module Status) light on Module DRT2-DA02 is Green.
- NS (Network Status) light on DRT2-DA02 Module flashes Blue

- The screen displays an error message “Configuration error I/O driver DN2DRV”.

 Can everyone please check if the above connections are correct with my control requirements and please check the 2 DEVNET.INI and IOSYS.INI files that I configured below to see where they are wrong and help me fix them? Thank you very much everyone.

Thank you for your response. I think the Node address in the 2 Modules is different: in DRT2-ID16-1 it is: 10, and in DRT2-DA02 it is 21. Can you explain where it is similar and how to fix it? Thank you.

You have two nodes with same address, fail, every node needs unique address. So devnet.ini is wrong.

You need only two resistors, one at each end of the bus.

In iosys.ini you must move the [DEVNET] section before [END SECTION]

Just the three first and easy to find fails

Descriptions of connections on i/o side of the modules at this stage aren't necessary, as long as you haven't created a short, it doesn't matter.

When having problems with devicenet modules it's a good idea to connect only one, and try to configure everything until it works. Then adding the other ones.

I put one resistor at the beginning of the MCF3 circuit, 1 resistor at DRT2-16-1 and 1 resistor at DRT2-DA02. where is there an extra resistor? can you explain it to me. thank you.

This is the edited IOSYS file, can you help me see if there is anything wrong, the Configuration error I/O driver DN2DRV error still hasn't disappeared. Thank you.

(Gigital Input Module DRT2-ID16-1 with actual Node Address is (X10=1, X1=0). Analog Output Module DRT2-DA02 with actual Node Address (X10=2, X1=1). Module DRT2-DA02, DIP on Module DRT2-DA02 has the following positions: (2,5,7,8 ON, 1,3,4,6 OFF).)

Thank you. Here is my connection diagram. Does it look correct?

Thank you very much. Tomorrow I will remove the 120 Ohm Resistor in the DRT2-ID16-1 Module and check it. I used 24V power supply from the 24V source in the electrical cabinet through the fuse to the V+ and V- pins.

Sorry, thought that you have three modules. Haven't seen your pictures, they weren't there when I red the post. So the digital i/o is only one module, addresses are OK.

But in devnet.ini you must change [3] to [2]. You have two modules, so you should have sections [1 ] and [2].

As already told you need two resistors, when you have three, you have one too much. The resistor at digital i/o module is the one you must disconnect. It is in the middle of the bus, not at the end. From there your bus is continued to the A/D module.

I have 3 Modules, but XWT-OD16-1 Module is an extension Module of DRT2--ID16-1 Module so I think it shares the same address with this Module.

Thank you very much. After fixing the errors according to your instructions and removing a resistor in the DRT2-ID16-1 module, I was able to remove the "Configuration error I/O driver DN2DRV" error. The MS (Module Status) and NS (Network Status) lights on the 2 Digital DRT2-ID16-1/Analog DRT2-DA02 modules have turned to a stable Green color.

Can you tell me why the Robot Axes have to be Mastered again after I cold start?

And can you give me more instructions on how to Map the connected devices to these 3 modules? Thank you very much.

That's because of the error 284 ("Accu Voltage") in your first photo. The KRC2 cannot retain Mastering through a Cold Start unless the batters (two 12V sealed lead-acid motorcycle-type batteries, located in the bottom of the controller) are healthy and charged. These batteries generally need to be replaced every 3 years. After replacement, leave the KRC powered up for at least 12-24hrs to ensure the batteries are fully charged before shutting down again.

Thank you very much for taking the time to answer my questions, sorry for the slow response. Regarding the Robot's battery, I have replaced 2 new batteries for the Robot, and charged it for more than 12 hours, but it still does not clear the error. I have consulted many previous questions but no one has a complete answer to clear this error, so I have not opened a topic about this issue.

As for the issue of connecting Devicenet devices, I have completed it, now there is the task of mapping the devices to the Controller. Do you think I should close this topic and open another topic about how to map external devices to the controller (V)KRC2ed05? Thank you very much again.

Thanks for replying me, sorry to read this message now, I have not been online for a few days. About this error I will probably close this topic. Currently my Robot is having errors about Safety issues, so I will open a topic to discuss it. Once again very grateful for your help, thank you very much.
