Simulink Real-Time non-Speedgoat Machine EtherCAT PCIbus selection

Hi, i'm trying to control a motor through EtherCAT communication.

I'm using Matlab2020a and I think I successfully setup my target PC(IMB-155b motherboard) which is non-speedgoat machine (as it passed slrttest)

But the problem is that it cannot find the ethernet controller for etherCAT communication.

Using getPCIInfo, I checked the list of ethernet controllers, and results are as follows:

>> tg.getPCIInfo('ethernet')

List of installed PCI devices:

Realtek RTL8168B

Bus 2, Slot 0, Function 0, IRQ 3

Ethernet controller

VendorID 0x10ec, DeviceID 0x8168, SubVendorID 0x1849, SubDeviceID 0x8168

Released in: R2011b

Notes: Realtek Gigabit Ethernet series

Realtek RTL8168B

Bus 3, Slot 0, Function 0, IRQ 16

Ethernet controller

VendorID 0x10ec, DeviceID 0x8168, SubVendorID 0x1849, SubDeviceID 0x8168

Released in: R2011b

Notes: Realtek Gigabit Ethernet series

The second ethernet controller(3,0,0) is used for host-target communication.

I want to use the first ethernetcontroller(2,0,0) for etherCAT communication, so I set my etherCAT init block like below and built simple block diagram.

But it gives error message:

Execution started (sample time: 0.010000)

Error: No valid Ethernet board found at bus 2 slot 0 function 0

Error: Execution cannot be started

Initializing application...

Error: EtherCAT Init: Ethernet port at [2,0,0] in use by raw Ethernet.

Error: Execution cannot be started

Since I'm new to using simulink real-time, I must be missing something.

Can I get help?

Thanks.

Hi TaeHo,

In my exprience, this often points to an issue in the ENI file used by your driver blocks. I would suggest reaching out to the MathWorks support to sort this out.

Best,

Dimitri

Hello, I have the same error as yours.

have you solved it? could you help me?

For my case, the ethernet chipset's compatibility was the problem as Gobiha explained below.

Your target PC should contain appropriate EtherCAT compatible chip set.

You can check the EtherCAT compatible ethernet chip set lists from below link

thanks, I will check it out!

Starting from R2018a, Simulink Real-Time only supports Speedgoat target machines. Besides Realtek Ethernet series are not supported for EtherCAT communication even prior to R2017b. Refer to the following documentation to see the list of compatible Ethernet chip with EtherCAT:

Hi,

you might have two main problems:

• Downgrade your Matlab to R2017b
• EtherCAT is only compatible with Intel chipsets. You have two NIC with Realtek chipsets. Try to install some Intel I8254X chips.
