Solved. Enable this feature by editing C:\ProgramData\CODESYS\Devices\89\0000 0005\4.4.0.0\device.xml (config params 9105 and 9106).

Post by sonnh on How to use more 4 instances of CANopen/Profibus/Modbus with The application-based license CODESYS Control CODESYS Forge talk (Post)
The codesys application license allows the use of up to 4 fieldbus instances (eg Modbus). I need to use more instances than that. Can I use the Modbus library instead? Does this usage require a license? Similar to other libraries such as CanOpen, Modbus TCP...

Post by timvh on Unable to Connect to Modbus RTU Device CODESYS Forge talk (Post)
If your Control Win is the Modbus "Master" then your configuration should be something like: Modbus_COM (Serial port) - Modbus Master (this is the Control Win SoftPLC actively setting up the communication) - Modbus Slave (this is then your WAGO 750-315) You need to add channels to the Modbus Slave configuration to inform the master which variables to read/write from the Wago module. The way you configured it now, the Control Win is also a slave. PS, don't forget to put the PLC (Control Win) in Run.

Hello, Today I am able to test ma industrial computer in my test bench. I am able to do all the configuration throught my VPN, 100% remote. I can see the gateway & the Virtual PLC. Now I would like to do some Modbus TCP Client & Modbus RS485. But I am lost due to docker ! When I go to modbus TCP it only gave me the docker network, but not my eth0 & eth01 When I go to modbus rtu, how can I create the link between Com number & my /dev/ttyRS485 Loic,

Post by hwopereis on How to use Application Trigger in Modbus TCP Server CODESYS Forge talk (Post)
Hi, I'm currently reading and writing several registers with a Modbus TCP server as a subdevice of a Modbus TCP Client. If I read and write cyclically, there are no issues. The problem is this: I see there is also the option to write by "Application", which I would like to use. However, I don't know With the Modbus RTU client, I see there is a trigger variable, xTrigger, to trigger the writing tasks. However, I can't find any such trigger for the Modbus TCP Client. Does anybody know how to implement the trigger behavior for the Modbus TCP client? In particular, I struggle to find the exact "trigger" variable. I'm running Modbus Client version 4.4.0.0 Thanks in advance!

Post by mavitia on Application based license problem - Modbus TCP CODESYS Forge talk (Post)
I am running ubuntu on a raspberry pi, and installed an application based license Control Basic M on it, it runs a demo program fine, does not timeout etc. however, when I add a modbus TCP device, I start getting errors: <Entry severity="error" component="CmpApp" user="nobody" timestamp="12/18/2023 3:49:42 PM" infoId="24">Online change denied. Application Application is in exception state!</Entry> <Entry severity="error" component="CmpApp" user="nobody" timestamp="12/18/2023 3:49:42 PM" infoId="68">Download failed: Application=Application</Entry> <Entry severity="exception" component="CmpApp" user="nobody" timestamp="12/18/2023 3:49:41 PM" infoId="0">Application app=Application has invalid license metrics!</Entry> the modbus tcp slave runs, and the counter ticks up, however, when I call the variables on the %IX0.0 in my program, and try to upload the changes, I am getting the error messages which stop the program as far as I understand, the application based, M includes 2 fieldbus instances, but on the other side is fairly new, anything obvious I am missing out here?

Ich würde gerne bestimmt Modbus RTU Slave Adressen auslesen, leider bekomme ich keine Werte vom Bus. Verbindung erfolgt über einen Raspberry mit Modbus RS485 Adapter, welcher erfolgreich verbunden ist. Mit einem IOBroker kann ich die Daten erfolgreich auslesen. In der Modbus_COM_Port => Modbus_Serial_Device habe ich Input Register 4000 %QW und Startadressen auf Input Register 3000, als Variable ein Array[0..2999] of Word, kann aber keine Werte auslesen.
