Why can't a property be of type REFERENCE TO? Plc goes to stop if I try that.

Post by atone on Change IO-Link Device Interface connected to a Profinet-Slave at Runtime ^{CODESYS Forge talk (Post)}
I need to be able to update (change) the interface of an IO-Link device at runtime. The reason is the connected sensor can be selected at runtime, and some sensors we use have a 2 byte IN interface, others have a 4 byte IN interface, others 16 byte IN, others 16 byte IN/OUT (see attached screenshot). Is it possible at all? When yes, which function should I use? Thank you!

Post by timvh on How to implement an interface (IElement)? ^{CODESYS Forge talk (Post)}
See: https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ This contains an application "OnlineChangeSafeLinkedListExample". What you should do is create a new interface which has your "Priority" property. Then your FB should extend the base element function block and implement your own interface: E.g. FUNCTION_BLOCK MyElement EXTENDS COL.LinkedListElementBase IMPLEMENTS I_MyInterface Then the __QUERYINTERFACE does the magic to check if your "element" also implements your interface. Something like this: // Compares this element with itfElement. // Returns 0 if the elements are equal, < 0 if the element is less than itfElement, // > 0 if the element is greater than itfElement. // This method will be called from sorted collections (e.g. |COL.SortedList|) to sort the elements. // IMPORTANT: The underlying value to be compared with MUST NOT be changed during the lifecycle of the object. METHOD ElementCompareTo : INT VAR_INPUT (* The element to compare*) itfElement : COL.IElement; END_VAR VAR itfIntElement : I_MyInterface; xResult : BOOL; END_VAR // We use integer iInt1 for sorting. xResult := __QUERYINTERFACE(itfElement, itfIntElement); IF xResult THEN IF iInt1 < itfIntElement.Priority THEN ElementCompareTo := -1; ELSIF iInt1 > itfIntElement.Priority THEN ElementCompareTo := 1; ELSE ElementCompareTo := 0; END_IF ELSE ElementCompareTo := -1; END_IF

you need to set the increments to 10 (the screenshot shows 10000 hex = 65536). all the turn settings to 1. and the application units to 366. But usually you use the resolver resolution per motor turn. Insert the gear ratios (1:1 for no gear) and the last field you put the circumference of your drive wheel.

Post by pazderai on CanOpen write issue ^{CODESYS Forge talk (Post)}
Thank you for an answer. Unfortunatelly, it doesn't work. The slave needs command byte as follows 0x22. It means expedited transfer where s-bit is not set, therefore data length is not specified. If I use segmented mode by CiA405.SDO_WRITE_DATA it produce command byte as follows 0x21 which is unfortunately supported by the slave and it returns with error 0x05040001 - SDO Abort Code -Client/server command specifier not valid or unknown. I can use CAN API low level to overcome this problem where it is possible to set 0x22 as a command byte, but than I can use user interface to set the communication probably, because I thing that machine expert uses library CiA405.SDO_WRITE for setting the slave. Or am I wrong?

Hi I need to update by software some structures in my datasource, i found this example: https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_update_data_interface.html it seems that because i use complex variable structure i need to use UseDataExpanding() instead of use data, the question is how to get an instance of IDatasourcesMgr3 i have the global variable g_Datasources is instantiated automatically
