Post by jp23 on Unable to Connect to Modbus RTU Device ^{CODESYS Forge talk (Post)}
Hi all, I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1). Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."

You use very old codesys, maybe SP13? the newer sp17 libraries are in a format not compatible with your version. I suggest upgrading everything to at least SP17, but may as well go to SP20 Patch 2.

Post by thysonfury on OPTO22 Groov Epic PR2 Modbus Comms Dropping out every 2 hours and 4 Mins ^{CODESYS Forge talk (Post)}
Hi after some assistance with an error on a Groov PR2 PLC. We have a few different communications set up as shown below: One Modbus TCP Slave Connection - ( Sending / Receiving Data from a PC ) Two Modbus TCP Master Connection - ( Reading Data from a UPS Panel and Reading Data Gas Chromatograph) One Modbus RTU Slave Connection 485 - (Reading Data from a fire and gas panel) One Modbus RTU Master Connection 485 - (Sending Data to a Telemetry Unit) All Licenses have been installed as per OPTO22 suggestions of the order below: Modbus TCP Master Modbus TCP Slave Modbus RTU Master Modbus RTU Slave When I check on License manager the RTU Master license seems to disappear on installing the RTU. (What ever reason I’ve been told this is “normal”). If I use Device License Read It will successfully read all the licenses correctly. Now the issue is every 2 hours and between 4. For what ever reason the communications seems to end and lock up for about 20 seconds. During this time even if I was logged into the PLC it would kick me off and I’d have to re type the password to enter. Most of the devices can handle this however the RTU flags up a communications failure at the SCADA and is raising alarms every 2 hours and 4 mins. We’ve had multiple people go through the code to check for anything obvious. Does anyone have any ideas?

Post by jf-fischer on PFC200 als Protokollumsetzer ^{CODESYS Forge talk (Post)}
Hallo, ich möchte IEC 104 Protokolldaten von einem Gerät über Ethernet empfangen, in ein Modbus-TCP Protokoll umwandeln und weiter geben (lesen und schreiben) an andere Modbus Geräte. Dies soll auch in die andere Richtung funktionieren, so dass daten aus dem Modbus Register vom IEC Gerät ausgelesen werden können. die Umwandlung soll eine pfc200 sps von wago durchführen. am Ende sollen die Daten in einer Webansicht visualisiert werden. das Programm der wago möchte ich in codesys 3.5V programmieren. Kann mir jemand helfen, meine Erfahrung mit Codesys ist leider bis jetzt nur sehr grundlegend.

Which versions exactly are involved? Runtime on PI? CODESYS Version and compilerversion?

Post by bfunk on Wago 750-8101 (mit Codesys V3) als Profinet device ^{CODESYS Forge talk (Post)}
Moin, ich habe da ein Problem und komme einfach nicht weiter... Ich moechte eine Wago 750-8101 (mit Codesys V3) zu einem ModBus TCP Slave und einem Profinet slave machen. ModBus habe ich hinbekommen, Profinet bekomme ich einfach nicht hin. habt ihr das evtl. einen hilfreichen Tip fuer mich? Programmiert wird mit Codesys V3.5 SP19 Patch 2 Auf dem Zielsystem (PFC100) ist die Zielsystemversion 4.6.0.0 Das es nicht optimal ist PN und ModBus TCP auf einer Schnittstelle zu haben ist mir bewusst. Wollte aber erstmal ModBus und Profinet zum laufen bekommen bevor ich das Profinet auf die 2. Ethernet-Schnittstelle bringe. /etc/CODESYSControl_User.cfg [SysSocket] Adapter.0.Name="br0" Adapter.0.EnableSetIpAndMask=1 Adapter.1.Name="br1" Adapter.1.EnableSetIpAndMask=1 ist eingetragen. so sieht der Status fuer das PN-device aus. Anbei ein Screenshot.

Also, this solution is not valid for the RTU, I imagine that this bug should be a high priority...

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hi, i found a solution for me. I had installed a 'old' version of CoDeSys (3.5.18 P5). I tried to add channels there, which works fine. I created a new project, added an Ethernet-Port, added a Modbus-Master and then I copied the ModBus-Slave from my working project to the new project. Now I could add more channels. I add the channels 10 and 11. Then I deleted (please make a backup before :-) the original ModBus-Slave in my working project and copied the extended Slave back to my working project. Surprisingly it is now possible to add new channels. Maybe this will help you.

Post by tokamk on Dynamic setting of the modbus tcp/ip slave ip address ^{CODESYS Forge talk (Post)}
Hello, I'm working on a project which includes Panel-PC which communicates with a PLC through Modbus TCP/IP. On the PLC I have a CODESYS code which has Modbus slave objects. The Modbus slave objects have to have manually set IP address in order for them to work properly and the Ip address has to be the PC-Panels's IP. This project is going to a customer and they're using their own IP address realm. So, my question is that is it possible to configure these slaves in some other way, so that the customer doesn't need to modify the CODESYS project? I was thinking that would it be possible to set the IP address of these slaves from external source?
