I found out that when booting from sd-card the usb to ethernet adapter is recognised ok. Only when i boot from usb (using a M.2 Expansion Board voor Argon ONE) different USB to ethernet adapters will not be recognised at boot time.

Certainly, You need to execute the following steps: 1. First place the socket variable at a %MD and also xopen and xclose should be placed at a%M. 2. Secondly define some eventroutines when the socket should be closed to prevent it from being reoped / reused. You can do this in Taskconfiguration->System events. 3. Now yo need to define the event routines Start socket server Stop the socket server - called before the application stops Stop the socket server - called before an online change Stop the...

Thanks for your help. runtime restart was the solution. The problem was that the UGREEN USB 3.0 adapter was NOT on the list of hardware for the Raspberry pi. So I bought a USB 2.0 Belkin adapter, which was on the list of compatible hardware (https://elinux.org/RPi_VerifiedPeripherals). However the're is a problem with both network adapters when booting the Raspberry pi. The are not recognized at boot time. So rebooting was not an option. Using eth0 would probably work. What i tried is using the USB...

I have a very simple demo application using a: - Raspberry pi 4b. - UGreen 10/100/1000 MB USB 3.0 networkadapter. - Codesys soft-PLC for the raspberry pi (Codesys V3.5 SP17 Patch 2 64-bit). The demo applicatition looks as follows: What have i done: - I've downloaded the xml descriptor files. - Inserted the EtherCAT Master. - Inserted a buscoupler. - Inserted a EL1008 DI module. - Inserted a EL2008 DO module. When start the application i get the following messages from the logging: Scanning doesn't...

I have downloaded an example project for a TCP socket server running on a Raspberry Pi. Code copied from the example for socket communication Linux SL. See the code below: TON1(IN:=xOpen, PT:=TIME#30S); IF hMySocket = SysSocket.SysSocket_Interfaces.RTS_INVALID_HANDLE AND TON1.Q THEN // create a socket for an IPv4 TCP stream hMySocket := SysSockCreate( iAddressFamily := SOCKET_AF_INET, (* SOCKET_AF_INET for ip4 connection. We do it locally, so it is a loopback *) diType := SOCKET_STREAM, diProtocol...
