Maybe your question makes sense but I don't see it. Maybe you should rephrase and add a lot of detail

Hello, I use Codesys 3.5 SP18 Patch 4 (64 bit) My Codesys project is composed of several dozen of Modbus TCP Slaves. I want to configure each of them by define : - Modbus TCP Slave Configuration : Name, IPAddress, port - Channels - Mapping I can't afford to configure manually and I need to find automatic way What possibilities does the Codesys offer? 1. I know it possible to use python script to create Modbus TCP Master and Slave. But I don't find anyway to create Channels and Mapping through the API 2. I 've tested to set mapping with file.csv on a Modbus Tcp Slave, but no way to import channels definition from file 3. I 've tried to use PLCOpenXml file. For example I 've create a project with an Ethernet device. I've exported it in PlcOpenXml file. After delete the Ethernet device, I've imported the PlcOpenXml file without success. I've tried the same by creating Modbus TCP Slave. Could you help me to find to good way ? Thanks

I'm having the same issue.I think it may be something related to the device adress that changes depending on the network i'm using, but now i don't have access to the one i used while setting my user. Did you find any solution for this?

Can you post the new code that you have by chance? Also, are you able to send the values of tags dynamically with the RTAC in this JSON format? I'm running into a lot of road blocks with it.

Das ist normal. Nicht alle Properties gehören der Cyclegroup Entweder du führst manuell die Methode Read aus oder änderst die Gruppe für das Property explizit.

the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?

Could you check the taskcycle time in the taskmonitor (online monitor) - do you really see this 1s on Ethercat Task? Need to check this on my hardware but will take some time...

Hello, I’m in Codesys 3.5.20.40 and I try to declare the variable ´var1´ but I get an error. here : https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_rules.html i read : Backtick identifiers By using backticks, characters can also be used in identifiers that are not normally permitted in identifiers, such as special characters. The acute accent character is used for backticks: ´ (Unicode: U+02CA) The use of backticks is recommended in order to be able to use the same identifiers in CODESYS as in other programming languages or documents, such as circuit diagrams. Any character may be used between two backticks, except line breaks and other backticks. Keywords are also allowed as identifiers between backticks. Examples: ´Variable+9´ ´INT´ The backticks are part of each identifier and therefore var1 and ´var1´ are two different identifiers. Example PROGRAM PLC_PRG VAR var1 : INT; ´var1´: INT; END_VAR var1 := var1 + 1; ´var1´ := 12; Are there any limitations or is something missing in my development environment?

Hi ducng, please make sure to call all Motion-FBs in the EtherCAT task. In your case, the PLC_PRG should be below the EtherCAT task, not the MainTask. Best regards, Georg

You never stay in a method. You need a block to do that. Something like: VAR button:BOOL:=FALSE; count:UINT:=0; END_VAR IF button THEN //read pressure count:=count+1; IF count>1 THEN button:=FALSE; count:=0; END_IF END_IF

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
