Post by micik on "CAA" meaning in library names CODESYS Forge talk (Post)
Hello, what CAA stands for? Since it is a collection of different libraries, does it mean it is created by some specific organization? Thanks!

Post by sturmghost on Visualization using methods and cyclic ST-calls CODESYS Forge talk (Post)
I found a way to do it: You can use, for example, the text variable property of any visualization element and call a function in it. Example: Write a test POU as a function (FUN), like MyTestFun which need a boolean Variable as an input value. Now write into the text variable property: MyTestFun(bBooleanValue) Thats it. The function is called at each visu_task cycle.

Post by mase on Python script: Launch Codesys, Execute Script, Exit Codesys CODESYS Forge talk (Post)
Hi, sorry I can´t help you with your issue, but I hope you can give me a hint on getting GUID for other objects than POUs. Your code states "Guid("6f9dac99-8de1-4efc-8465-68ac443b7d08")". We can I find the GUID / ObjectIds`? I wasn´t able to get details about the GUID of DataTypes (STRUCT/ENUM,..)m, Functions (FUN), GLOBALS and TYPES. I want to create markdown of all available project elements. Thanks for your help

I've post the Versions in the Attachments. It seems with htop, that there is a very high CPU Load. In the Log I can see nothing, as mentioned above I've to restart the PLC with Power off/on and the log in codesys was deleted. Or what do you mean with plclogger?

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE CODESYS Forge talk (Post)
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Post by rmaas on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia CODESYS Forge talk (Post)
Hi, Im not sure if this is what you mean, but i do succesfully use the IoDrvEthercatLib.ETCSlave.InputData and IoDrvEthercatLib.ETCSlave.OutputData to read from and write to beckhoff DI and DO cards. Very convenient as you can make an FB with an VAR_IN_OUT of type IoDrvEthercatLib.ETCSlave and only have to pass the slave reference... So i am not using .ETCSlave_Diag but .ETCSlave...

What does this message mean, in the Errors/Messages box? "[ERROR] MyProjectName: No Offline Help installed" In CDS23, I used to be able to select a system function with the mouse, and press F1. Help and description would popup. How do I get so-called On-line Help installed?

Post by jeffgamsby on Accessing ModbusTCP addresses from python CODESYS Forge talk (Post)
Hi, I am new to modbusTCP and I am trying to access Input registers from codesys (3.5.SP13). The offset is 16#0000 and I am trying to access Channel 1[24] %IW24 to pull analog values. I am using pyModbusTCP and I need to supply a modbus address and the number of registers to read. What does 16#0000 mean in terms of the actual offset, how do I translate this number plus the channel to access this info via python? Any help would be appreciated, thank you.

Post by trusty-squire on implementing continuous movement in Codesys CODESYS Forge talk (Post)
What do you mean by continuous movement? You want to continuously follow a dynamic target position? SMC_ControlAxisByPos, which is typically used with CNC Interpolators, could work for that. Instead of feeding the target position in from the Interpolator, feed in the target position from your server instead. Once you enable the FB, it will continuously move the axis to track the fSetPosition input. https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/SoftMotion-CNC/Direct-Axis-Control/SMC_ControlAxisByPos.html

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) CODESYS Forge talk (Post)
Thanks for this - I have now been looking in to just having an extra (non-RTE) runtime on the same machine, as you suggest. I will probably proceed this way. Even though it still seems very odd to me, that variable exchange to a different runtime is easier than between applications on the same controller. There will be some fun with the licensing, it seems. Does anyone know if it is possible to specify which license container/specific license the runtime is going to use at runtime. Let's say I have two available licenses with different resources available, for example one license allows multicore and multiple EtherCAT channels, but not many visu tags (for the RTE). Another with less resources but a lot of visu tags (for the Visu controller). Let's say the program in one of the controllers could be fully licensed by either of the two available licenses, but picks the 'largest' first. A bit later, the larger application starts, but is left with the smaller license.. How can I make sure that the 2 runtimes select the right license at startup?

Post by riccardo on Management of a PLC network from a remote station CODESYS Forge talk (Post)
Goodmorning, I would need to set a control station that can manage a PLC network. In short I need to access to all visu programmed in any PLC of the network (LAN). I was thinking to use a PLC with buttons that call, by mean an IP address, the visu of any PLC. I don't know if it is possible but I saw that there is a RemoteVisuTarget that run CODESYS Control Win V3. Can someone suggest me how to create a remote main control station from a normal PC? Thanks, Riccardo

Post by joanm on Programmatically change the IP addresses of the Modbus TCP slave devices CODESYS Forge talk (Post)
Hello all, I am working in a project in which there are multiple Modbus TCP slaves. I need to be able to change the IP addresses of those devices from the HMI and I was planning to use the process depicted here: https://faq.codesys.com/display/CDSFAQ/Modbus+TCP+Slave%3A+Dynamic+Setting+of+the+IP+Address I can see the port number is what is used to specify which slave device we want to modify the IP address of. This said, can I freely set arbitrary port numbers to each device? I mean, can I set the first device to be at port 502, the second one at port 503... Any drawback or restriction? Is there any other way to reference to the device without having to change the port numbers? Thank you all in advance.

Post by davidbo on Does the new license policy means I have to upgrade everything? CODESYS Forge talk (Post)
We have several old project written with 3.5.17 and 3.5.18 and also some older Until now when a customer ordered a product from us. We just installed (we have a tested image) and added a license Now the license policy has changed and we have to buy a License Control Basic S or M However it only works with CODESYS Development System Version 3.5.19.10 or higher Does that mean we have to upgrade all our old products? That is not a simple task as a previous post has explained with weird error messages from CODESYS V3.5. Next we have to do rigorous testing of our applications afterwards. It is very expensive

Post by andre-luis on Check if Codesys runtime is on 'Running' or 'Stopped' state? CODESYS Forge talk (Post)
Hi there, I'm running the Codesys runtime on Windows 64 and I need to know if it is on "Running" or "Stopped" state just after a system crash. The following commands works perfectly well to (re)start it... net stop “CODESYS Control Win V3 - x64" net start “CODESYS Control Win V3 - x64" ...however I'm unable to determine when it is required to be call; I mean, by checking the System Tray icon, it is possible to know if it is on "Stopped" state, but I wanted to run a .BAT command to retrieve it. How can we do that?

Post by rcaponi on Codesys Control RTE V3. Remote Control CODESYS Forge talk (Post)
Hello, I would like to have, if possible, some clarification on this function. That is, I would like to understand if it is useful for managing, fom my development PC, the RTE runtime executed on a remote control. This is what the help says: Remote PLC: Opens the Remote Configuration dialog. By enabling or disabling the Control remote PC, not local option, you determine whether a PLC is used that is on a remote or local PC. Accordingly, the menu commands Start PLC, Stop PLC, and PLC Configuration refer to the local PC or a PC reached on the network. For the remote PC, specify the Target PC address, Port number, and a Timeout value (in ms) for the connection (Remote Timeout [ms]). But does this mean that I also need to install the RTE runtime on my development PC? Is it possible to have some more information? Best regards Roberto Caponi

Post by riccardo on VisuElems.CurrentUserGroupId is not stable CODESYS Forge talk (Post)
Goodmorning TimvH, Thanks for the reply. I don't know if your solution solve my trouble yet, I am going to see the link you sent me. In the mean time I try to explane better what I need to do. I have a turbine system that get in alarm under some condition (E.g low speed of turbine) and block the itself. When the system is stoped there is no speed turbine and the system cannot start. To give to the operetor the possibility to bypass the alarms, there is an acknoledgement alarm pushbutton. This bypass must not work for everyone but only for those client that perform the login by (User Management). Furthermore, if the user perform the (manual or automatic) logout in alarm conditions, the acknowlegment must be annulled and block the system again. To do this, I need to know if an operator is logged in the page and is working to fix the problem; otherwise the syste must autoturn off again. Now I go to study your solution, if I have explaned better and you have another idea tell me please.

Post by jackbrady on Function Blocks and arrays of function blocks CODESYS Forge talk (Post)
Hello, I am new to Codesys and PLC programming in general (please go easy ha!) I'm not looking for code to be written for me just some help and pointing in the right direction. I am writing some code to send commands to a relay based on input values (to put it simply). Quite basic stuff. I have wrote a function block that takes a global variable (Open_command:BOOL) and outputs to another global variable (Opened : BOOL). The function block is simulating a device so I'll eventually get the globals from that. I now need to create multiple versions of this function block/ device (lets say 100) but I need each iteration of that function block to reference it's own relevant global variable. I think that the best way of doing this would be to use arrays, although I could be wrong. I am aware that for up to 100 instances I could very well manually assign everything but that seems rather time consuming and I want a fancier way of doing it. Here is a very basic example of what I am looking to do, please note I have not written this in proper code it's just to show what I mean. Global Variables V[0-100] int Open_command [0-100] Bool Opened [0-100] Bool Function Block var input x : BOOL Var output y : BOOL if x then y = TRUE ELSE y = FALSE The input to my function block will be Open_command, output will be Opened Example code. If V[x] > 10 then Open_command [x] = TRUE ELSE Open_command [x] = FALSE (So when V1 goes above 10 I need Open_command1 = TRUE therefore initiating FB1 output. V2 > 10, open_command2 = True > FB2 output V3 > 10, open_command3 = True > FB3 output ... ... ) What I can't seem to figure out is how to tie all this together, I have read through the codesys documentation and if anything it has confused me more! ha. Apologies for the poorly written post but hopefully you understand what I am trying to get at. Thanks, Jack

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
