Hi everybody, I would like to ask you if you know how in Codesys has been foreseen the management of multiple ethercat slave configurations. I have a machine with several I/O nodes, changing based on the machine configuration. I would like to activate the correct configuration during the start up of the application. Do you know which is the most automatic possibility in Codesys > 3.5.16? Thank you very much in advance. Best regards

Thank you very much for your quick response! Well, for not creating a property for each field of my Structs, I am using the property to access the complete struct. E.g. PROPERTY robotStatus : REFERENCE TO ROBOT_STATUS Get property becomes: robotStatus REF= l_robotStatus; Where l_robotStatus is the local struct declared in the FB. So even if I declare only the Get property, when from external I access the robotStatus property I can also change the data cause as far as I have understood is a REF property,...

Hi everybody, I need to access few Struct data declared in one FB. Under these helpful forums I found the way to declare the GET method (using REF=). But I haven't found this thing: if I want to allow just the read of a struct is there a way to do it? Using the REF= declaration then from the extern I can also change the data in the struct. Thank you very much. Best regards.

Hello, thank you very much for your answer. Just one more thing, do you strictly recommend to reduce the use of string comparison or because nowadays the cpu are very powerful so the time for string comparison is also negligible? Thank you. Best regards

Hi everybody, I have a curiosity about the string comparison. I'm using the = operator to compare strings in one of my function block. The question is: How much the performances change compare to a comparison of an integer? Thank you very much. Best regards
