Post by muhq on Profinet connection to Siemens CP343-1 Lean (IO-Device/Slave) ^{CODESYS Forge talk (Post)}
Hi, I am quite new to Codesys and I try to do a Profinet connection to an Siemens PLC (315-2DP) with CP343-1 Lean Modul. I already configured the Siemens PLC, exported the GSDML. Then I added a new project in Codesys, added following moduls: - Ethernet - PN_Controller - Imported Profinet Device via GSDML importer When I start the programm everything looks fine but I always get the message "Stopped Profinet" and no data is available This is only for a small test. Therefore I start to do that on a Windows 10 with Development System. Later I will try to realize this on Raspberry. Ethernet Adapter is configured (192.168.1.1 / 24) Firewall deactivated WinPCap is installed S7-Station seems to be found ('fuadazenzitest') Can please somebody help me?

Post by idalu on Profinet PN_Controller Issue, Network Adapter ^{CODESYS Forge talk (Post)}
i have a problem with Profinet on my project. I'm using Codesys RTE 3.5.19.50. When i download program to controller the ethernet is ok, PN_Controller is ok but every device i'm trying to connect is red with error "DCP no RealStationName". When i'm trying to Scan for Devices on PN_Controller there are no devices found. I have installed Codesys driver CmpEt1000Drv to my network adapter (i'm sure it is right intel pro 1000 model). I have noticed that when i installed codesys driver i'm no longer able to ping this network adapter (i can ping it when intel driver is installed). On my previous projects with runetimes i can ping it even with codesys driver installed. I have also tried to do downgrade of everything to version 3.5.19.20 and it not helped.

The simplest way to do this would be to add a bus coupler dedicated to the expansion IO. The EtherCAT network does not fault when modules connected to the expander are not present. In the image below, nothing below the red line is present in the network - with the network working correctly. In your "base" project, simply include all of the possible modules, and then plug them in as you add pumps to the system. I would also highly recommend against the use of direct addressing. There are other methods to accomplish this, including using the "Optional" checkbox for modules and explicitly addressing them. Although, this would require more upfront work to design the network, and some additional work each time modules were added. https://content.helpme-codesys.com/en/CODESYS%20EtherCAT/_ecat_edt_slave_slave.html

Post by alexgooi on Codesys virtual control redundancy ^{CODESYS Forge talk (Post)}
Dear Forum, I’m currently investigating the possibilities of Codesys virtual control (Linux). The research rig consists of a PC (Debian with real time kernel) with a docker server installed on it. The PC is communicating with a Remote I/O and I have to say the performance is great. The process in the container is running (soft) real time. Currently I’m checking if it is possible to replace physical controllers by remote I/O’s and run the Codesys applications on a docker server. If I’m going into this route the reliability of the server is very important (server down, complete installation down), is it possible to make the server redundant without needing 2 separate containers (including licenses), and maintaining the real time behavior? I’m not only expecting direct answers, if you have any idea or thought they are very welcome. Kind regards Alex
