Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
thank you, i tried your library and device description but i don't get analog values. Do i something wrong? i also got an library error at the I2C_BASE functionblock the calcCycleTime gave an variable size error, so i added thet conversion from ULINT_TO_UDINT.

Post by mondinmr on First IO address of a CAADiagDeviceDefault. ^{CODESYS Forge talk (Post)}
I have a device CAADiagDeviceDefault: IoConfig_Globals.Axis_A In our library, we perform introspection of the Etc_SlaveDiag. In that case, we have connectors, and by searching for them by address, I can find them in the IO mapping using the offset and size provided by EtherCAT. However, a Lenze i700 drive, instead of placing the IO mapping in the Etc_SlaveDiag device, places it in a sub-device CAADiagDeviceDefault. So, when I perform introspection, I cannot find the IO correspondences. Yet, in the CAADiagDeviceDefault, I do not find the connectors and cannot do the matching. Is there a way with a pointer or reference to a CAADiagDeviceDefault to obtain the address of the first input and the address of the first output? This is because we have our own motion library with many EtherCAT devices that automatically configure the mappings, but I can't manage to do so with the Lenze i700.

Post by george32 on CSV file and string manipulation. ^{CODESYS Forge talk (Post)}
Dear folks, I think I have a rather simple question but I could not find the right answer to my question: I have made with Excel a CSV file where I would like to have some general data regarding my program variables. I have made an program what let me read the file. The string I am currently get is at follows: 'IP_Adres;192.168.45.12$R$NPort_number;2000$R$NCycle_time;43$R$NStart_Standard_IO;20$R$N' Now I want to split the string in multiple part, which I later would connect to the right variable. By Google and experimenting I have reached to the following code for the first part of the splitting proces: // Splitting the BOM of the string: Received_string := FileReadString; IF LEFT(STR:=New_string,3)= '' THEN Received_string_without_BOM :=RIGHT(STR:= Received_string,SIZE:= (LEN(STR:= Received_string))-3); END_IF //Splitting the remaining string in part for later declaration. WHILE index = 0 DO index_split_part := FIND(STR1:= Received_string_without_BOM,STR2:= '$R$N'); Part_of_String[index]:=LEFT(STR:=Received_string_without_BOM, SIZE:= index_split_part); index := index + 1; END_WHILE However in the splitting proces I could not understand what is really happening. I understand that the Find() function returns the first value the $R$N in the Received_string_without_BOM. This would mean that the index_split_part := 23 I|P| _ |A |d|r|e|s|;|1_|9 |2 |. |1 |6 |8 |. |4 |5 |. |1 |2 |$ |R |$ |N |P | 1|2| 3 |4 |5|6|7|0|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27| So the next part is to read the first 23 characters of the Received_string_without_BOM with the LEFT() function. I expected that the outcome the following was: 'IP_Adres;192.168.45.12$'. However the outcome is: 'IP_Adres;192.168.45.12$R'. I do not understand where the R after the $ sign comes from, because its place is 24 so it would not be added to the part_of the_string[index]. If I hard coded value 24 for the size it gives me the following return: 'IP_Adres;192.168.45.12$R$N'. I would expect everything till the R but the code adds the $N also to the string. I hope someone could explain to my what I am seeing wrong in my point of view? With kind regards, George

Post by mxj262 on FB having single input but initialized with Array ^{CODESYS Forge talk (Post)}
I am adding elements of an ARRAY using pointer to access each element inside a FOR loop and the FOR loop does not stop! What is the right way to use pointers in such case?? I have another loop that is not using pointer and it stops but the loop using pointer keep on adding. METHOD FB_Init: BOOL VAR_INPUT bInitRetains: BOOL; // TRUE: the retain variables are initialized (reset warm / reset cold) bInCopyCode: BOOL; // TRUE: the instance will be copied to the copy code afterward (online change) END_VAR VAR_IN_OUT // basically REFERENCE TO window_buffer: ARRAY [*] OF INT; // array of any size END_VAR THIS^.windowPtr := ADR(window_buffer[0]); THIS^.windowSize := UPPER_BOUND(window_buffer, 1) - LOWER_BOUND(window_buffer, 1) + 1; FUNCTION_BLOCK FB500 VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR windowPtr: POINTER TO INT; windowSize: DINT; currentIndex: UINT; element1:INT; element2:INT; i:INT; j:INT; sum:DINT:=0; END_VAR element1:=windowPtr[0]; // read the first element of the Array dynamic memorry element2:=windowPtr[1]; FOR i:=0 TO (TO_INT(windowSize-1)) BY 1 DO // this loop does not stop Sum:=sum + windowPtr[i]; END_FOR FOR j:=0 TO 5 BY 1 DO // this loop stops j:=j+1; END_FOR https://ibb.co/k3DhkZT
