Trouble to connect CAN with a XC100 and an EU5-SWD-CAN gateway.

[nicool67]

Hi to all!, im having really trouble to make a CAN connection between an XC100 PLC and a EU5-SWD-CAN gateway device.

The gateway shows the SWD led green, so the Darwin net is OK, but when i connect the CAN interface of the gateway to the XC100 the CAN led flashes green and never stops!. I dont know if the CAN connection is right, so i attached a picture that shows what im doing, could anyone told me if this connection is correct?.

In the gateway, i swithed on the first dip switch wich is supposed to activate the internal end of line resistor.

Thanks in advance.

Hello nicool67,

Your gateway shows the following LED-States:
POW   = Yellow.
CAN   = Flashing green (Pre-opereational –> CANopen connection OK.)
CONFIG   = Off (No SWD-Configuration has been submitted from the CAN-Master PLC)
SWD   = Green. The stored SWD configuration matches the actual SWD-configuraton.

The SWD-Gateway will not start until it has checked the available SWD-configuration against the configuration expected by the PLC.
Submitting the expected SWD-configuration is not supported by the actual XC100 targets, so all You need to do is to switch off this initial check.
In your PLC project go to:
Resources/PLC Configuration/EU5C-SWD-CAN and select the tab “Service Data Objects”.
There the value of index 2003 “Disable configuration check” has to be set to 1(Yes).

Best regards

Thanks a lot for the reply!, now im having new troubles!. I dont know what i modified but now im having a red blinking in the CAN led. Im panic rigth now!, ive checked in the gateway manual and it seem that is a CAN error.

I dont know what should i do!, can you give me any tip?. Is the connection OK?, is probably that i could have any trouble in the CAN configuration?.

Thanks a lot!.

Ok, there are four main reasons the CAN-LED may turn red.

Flickering (fast blinking) = The auto-bitrate detection is in progress, the gateway is trying to detect a valid CANopen-Baudrate. This state is reached after power-on or following a reset-device command. Make sure there is some traffic on the bus, Nodeguarding (Guard_Time / LifeTimeFactor) or Heartbeat (for XC100 and SWD-Gateway) has been activated.

Single flash = Error-warning state reached. There are communication-errors on the bus.

Double flash = Guarding-Error. Nodeguarding or Heartbeat has timed out.

On = CAN-Controller in bus-off state. No communication.

By the way, is your Node-ID setting correct?

Is the CAN connection OK ?
- In Online-Mode look at Resources/Bibliothek 3S_CANopenManager.lib/Globale_Variablen
gCanInterface[0].nRx_Index_IEC and
gCanInterface[0].nTx_Index_IEC.
If both variables rotate the PLC sends and receives CAN-messages.
- In Online-Mode look at Resources/Global Variables/CanOpen implicit Variables
   pCanOpenNode[X].nStatus
This variable displays the state of CANopen-device ‘X’ as it is suspected by the CANopen-Master state.
   0-3 initialisation
   4 ready to start
   5 running
   >5 error states

Ive tried and tried with no succes. Can you please give me a project example to make a simple test?. Im using an XC100 64kb PLC module, a EU5-SWD-CAN gateway and a M22 with a led. I cant make this to work, please help me.

Thanks in advance.

It worked!, the problem was int the XC100!. Thanks to all!. If someone wants an example please send me an email.

Best Regards,
Nicolas.
