In the Struct, change the 'BOOL' to 'BIT'

use the persistence manager. with the persistence-manager, you're aböe to define how, when and where you store your data

Post by amy123 on codesys mqtt publish serialization ^{CODESYS Forge talk (Post)}
Hello, I am using the CODESYS IIoT Libraries SL MQTT Publish. Does this publish block only support publishing STRINGS as a readable format? I can publish ENUM, STRUCT, BOOL; however, MQTT Explorer will only display strings. When I use Wireshark, I can see that it is publishing something, but it looks to be publishing a serialized version which is a bunch of 0s or random text. If so, is there any way to deserialize this information back into a readable format? See pictures, where I have a BOOL TRUE that gets published as 001. Then see where I publish a STRUCT and it's an incomprehensible combination of 0s - only the string variable is displayed. Or, is it expected that you convert everything to a string before publishing? Any help is greatly appreciated! :)

Post by jonathan1321351 on IO-Link write parameters Ethernet/IP ^{CODESYS Forge talk (Post)}
I want to read and write parameters of an IO-Link device using acyclic messages. I have a Cube67+ in Ethernet/IP, connected to an IO-Link master. In the datasheet, I can find the parameters required for the message (Service, Class, Instance, etc.). I see the function block "Set_attribute_single" in the "EthernetIP Services" library, but I'm not sure how to correctly send the index and sub-index for the IO-Link device. The class in the datasheet is 0x80 for the IO-Link Parameter Object, but it’s not present in the CPIClass enum. Is there another function block more suitable for configuring IO-Link devices? (similar to "iol_call" in PROFINET or what’s used in EtherCAT).

Post by scarter on Bit / Bool data types in function parameters ^{CODESYS Forge talk (Post)}
Any reason BIT and BOOL data types are not interchangeable? Trying to make a function which takes a BOOL IN/OUT parameter (Not allowed to use BIT) In the main logic if I make a DINT variable, and want to use each bit on different functions CODESYS will not allow it.

Post by kuegerls on SysProcessExecuteCommand2 and CANopen Device ^{CODESYS Forge talk (Post)}
I have now conducted some tests. The problem occurs when the Python script establishes an OPCUA connection, even if I only establish the connection without reading or writing any data. Is there another way to exchange data between Python and CODESYS without having to put in a lot of effort?
