Hello, I am trying to define a struct as an input variable for a Function or Function Block. For example the function AddDelimiter (This is a standard Sysmac function), has a input variable with the variable type Struct, an it is possible to couple a struct to this input (See picture below). If i try to make my own function block with a struct or Structure as an input data type, i get the following error (See picture below). When I try to define a struct from the data types (In this case struct: Test) it doesn't give a error. But when I try to couple a struct to this input, that is a layer deeper than the function block struct i get the following error (See picture below). How can i define a struct as an function/ function block input? Thanks in advance.

blackdawn posted a topic in Other PLCsHi Everyone I am using Wago 750-8203 PLC with an Atlas Copco MKIV local controller in my project. In this project I have used WagoCANLayer2_02.lib because the project requires me to use CAN Open protocol. I attach the function block diagram to read data from the local controller by sending the required CAN data. When I run the program it shows CAN_ BUS_IDLE error. I have given the right CAN_ID and data, I did not understand, Why I am getting this error. So please can anyone help me. Thank in advance for the help.
