Post by davidbo on How to stop dhcpcd and use SysSockSetIpAddressAndNetMask to set address? ^{CODESYS Forge talk (Post)}
It is stated: "Dynamic ip address, provided by DHCP, BOOTP, etc. Cannot be changed by SysSockSetIpAddressAndNetMask()" Therefore I try to stop dhcpcd and flush the eth0 like this VAR CONSTANT flushIP:STRING:='sudo ip addr flush dev eth0'; stopDHCP:STRING:='sudo systemctl stop dhcpcd'; END_VAR SysProcessExecuteCommand2(pszCommand:=stopDHCP, pszStdOut:=stdout,udiStdOutLen:= SIZEOF(stdout),pResult := ADR(Result)); SysProcessExecuteCommand2(pszCommand:=flushIP, pszStdOut:=stdout,udiStdOutLen:= SIZEOF(stdout),pResult := ADR(Result)); Besides losing the connection when flush occurs the CODESYS halts, seen on the display and I cannot see why, because I have lost the connection from my IDE. Why does the flush command halt the execution of the application?

Post by davidbo on What is the prerequisites for a Raspberry Pi to work with SysSockSetIpAddressAndNetMask() ^{CODESYS Forge talk (Post)}
I have done: systemctl stop dhcpcd sudo ip addr flush dev eth0 sudo ip link set eth0 up but a call to SysSockSetIpAddressAndNetMask does not give the eth0 an IP address Why?

The reason for why CODESYS halts was a CODESYS watchdog exception. 'sudo ip' takes a long time.

Hi Helpers I'm trying to work with stepper motor on Rasp 5 for the first time. So I'm pretty new.😥here. I've used: https://forge.codesys.com/drv/sm3raspistepper/home/Home/ but I get the following error when I insert. I also get 6 errors when I "rebuilder" after installering "SM_Drive_RaspStepper_direct" from the tree. Hope there is help for me. Thanks in advance /Klaus

Important: ` - Backtick - ASCII 96 ' - Apostrophe or Single Quote - ASCII 39 In the online help for some reason it renders ’ ...

Post by tobifenny on Modbus TLS Kommunikation ^{CODESYS Forge talk (Post)}
Ich habe eine Wallbox, die ich gerne per Modbus ansteuern würde. Die Normale Modbus-Kommunikation, um ein paar Werte auszulesen klappt auch. Wenn ich aber Zugriff auf bestimmte Modbus-Register haben möchte, benötigt die Wallbox ein TLS-Zertifikat. Das Zertifikat habe ich bereits erstellt und im Security-Sreen unter Eigene Zertifikate hochgeladen. Weiter komme ich aber nicht mehr. Wie baue ich eine TLS-Verbindung mit der Waalbox auf? Vielleicht hat das ja schonmal jemand gemacht und ein Beispiel für mich. Ich bin über jede Hilfe sehr Dankbar!

aktuell bin ich mir nicht sicher ob das Modbus/TCP Security Protocol unterstützt, ich check das mal. Hast du ein Handbuch zu der Wallbox?

Hier ist das handbuch: https://www.kostal-solar-electric.com/fileadmin/downloadcenter/kse/BA_KOSTAL_Interface_KSEM_DE.pdf Im Kapitel 1.3.2 ist das mit dem TLS beschrieben und in Kapitel 3.6.2 sind die Modbus-Register beschrieben.

Hallo an alle, ich schaue mir gerade ein paar 22kW Wallboxen an: https://shop.einfacheauto.de/collections/22-kw-wallboxen Mir wäre vor allem wichtig, dass die Kommunikation per Modbus gut funktioniert. Es werden zwar ein paar Wallboxen gelistet, die Modbus ermöglichen, trotzdem wollte ich euch nach Erfahrungen fragen, welche Modelle in der Hinsicht besonders problemfrei funktionieren.

Post by aris on Modbus write via FB failure ^{CODESYS Forge talk (Post)}
Hi all, I am using CoDeSys V3.5 and a soft controller Win V3x64. I am trying to read a modbus slave via Function Blocks and not via the channels of the hardware tree for the Slave. I created some requests of type ModbusRequest and I notice that I can read Input Registers and Coils but I can not write Holding Registers and Coils. I am using the library IoDrvModbusTCP 4.1.0.0. When i just use a single modbus request with FC06 (or FC16), there is no request sent to the slave and although the xExecute takes its true value from a pulse of 2 seconds duration, I take almost every 3 minutes an error "TCP_COMMUNICATION_ERROR - 16#A5 - TCP Port. error. Request was not sent". My code is ok because if i change the function code for reading registers, everything works fine. Did anyone have this issue in the past? Thank you in advance.

hi, das geht leider nicht mit aktivierter Verschlüsselung , sorry - denke aktuell bleibt dir nur auf Slave Seite die Verschlüsselung zu deaktivieren.
