Post by adaml on ScriptEngine - execute "Export -> Bootproject and firmware (SD Card)" from python ^{CODESYS Forge talk (Post)}
Hi everybody, recently I was checking how many time consuming manual tasks I can perform with python scripts through ScriptEngine. I have in the project many devices and currently I export bootprojects for them by right clicking on Application, then go Export -> Bootproject and firmware (SD Card) and then point folder where files should be exported. It's fine if project has few devices, but I have some of them with over 30 devices and manual clicking like that is very time consuming. How can I do it with python script? So far I found "create_boot_application" method from Application object (taken by projects.primary.find('Application', True)) but it only generates .app and .crc file instead of full structure to store on SD card (FIRMWARE, USERDATA, SDCARD.INI, Version, Version.txt.sig). Should I use some method to control user interface? Best regards, Adam

Post by naks on Change IP address from IEC code ^{CODESYS Forge talk (Post)}
Hi, I'm working with wago 750-8212 controller. I want to change the IP address of the Ethernet adapter from webvisu. I have read some other threads in this forum and I have tried the following: Added the following text to the config file CODESYSControl.cfg: [SysSocket] Adapter.0.Name="br1" Adapter.0.EnableSetIpAndMask=1 Used the below code : IF xUpdateEthernet THEN Ethernet.Enable := FALSE; Reconfig ( xExecute := TRUE, itfNode := Ethernet, eError => ErrorReconfig, xBusy => xBusy, xDone => xDone, xError => xErrorReconfigure); IF Reconfig.xDone THEN ErrorCode := Ethernet.UpdateConfiguredIPSettings(IpAddress := NewIp, gateway := newGateway, subnetmask := newSubnetmask); END_IF IF Reconfig.xDone OR Reconfig.xError THEN reconfig(xExecute := FALSE); END_IF Ethernet.Enable := TRUE; Reconfig(xExecute := TRUE, itfNode := Ethernet ); END_IF I could change the IP address but when i restart my Controller then the IP address resets to the original, Is there anything I have missed, what else can i try ? Thank you in advance.

Post by rcanfield on Code Coverage and Test Manager ^{CODESYS Forge talk (Post)}
I am exploring the possibility of measuring test coverage using the Test Manager and Profiler tools. It appears there are some significant limitations. Has anyone been successful trying to use these tools? Here are my observed limitations. Am I misunderstanding anything? * Profiler only works for one "run cycle". Even warm resets will clear the coverage calculations. Thus, all tests would have to manually reset values when complete to prevent contamination to other tests. * It is not possible to see which statements were/weren't executed. One would have to use the flow control tool which cannot be used in conjunction with the Profiler, and must be viewed in realtime. * The profiler control cannot be automated and therefore must be executed through a manual procedure. Thank you!

Post by alez on CANopen safety , SRDO error behavior ^{CODESYS Forge talk (Post)}
I have a project in which there is a Safety device in CANopen, and the PLC interfaces with it as Master. I would like to understand if it is possible to set the behavior in case one of the SRDOs that I receive from the slave is no longer received. From what I have seen, if the SRDOs are not received, the CANopen safety status becomes "Not in progress" and the mapped variables freeze at the last value detected. I want to understand if it was possible to set the variables connected to the SRDOs to take a default value (e.g. zero) in the event of a CANOpen error during reception.

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?

I want to display all incoming CAN messages for example first incoming CAN message - I assign it into a variable Message1. second incoming CAN message - I assign it into a variable Message2. third incoming CAN message - I assign it into a variable Message3. Can you give me guidance? Thank you BR

Post by drml on How to implement an interface (IElement)? ^{CODESYS Forge talk (Post)}
I'm struggling with the implementation of the IElement interface (in the ElementCollections library), which I will use to create a SortedList. I created a class (FB) "Device" that implements this interface and that has a "Priority" property that I want to use in order to compare the devices in my implementation of the ElementCompareTo method. Unfortunately, the IElement.ElementCompareTo method needs an IElement as an input, which doesn't know about the "Priority" property of "Device". I tried to define the input itfElement as a Device, but then it doesn't want to compile, because the type in the implementation doesn't match the interface.

Post by toffeebonbon on EL7041-0052 - does it run with EL7041 SoftMotion? ^{CODESYS Forge talk (Post)}
I let this project rest for a while and picked it up last week. I have been in contact with the support from beckhoff and got the information that the terminals were identical (communication wise). As the Log of the Axis (not the drive's log) shows the error when trying to write into the register 0x8012 and set the value for an encoder to a value that is the default - at least according to the manual - I was wondering if it is possible to "not write that value" to skip that part? Or am I misunderstanding the way the library communicates with the drive?

Post by dawidr on Best practices for querying multiple MODBUS devices ^{CODESYS Forge talk (Post)}
Hi! What are the best practices for querying multiple Modbus devices? Single PRG or maybe multiple PRG (so basically multiple thread) per each Modbus device. In my current implementation I'm using single PRG and I'm utilizing FbMbMasterMultiQuerySerial and WagoAppPlcModbus.FbDigitalTwinMbSlaveDevice in eCockpit with PFC200. I've the timer with 2 seconds delay there and it was working fine for single device. But now I have three Modbus devices and for two of them I need to run 2/3 queries to get data from all registers. I noticed that the delays for getting the data from the Modbus devices is much bigger right now.

Post by mubeta on parker servo and position ^{CODESYS Forge talk (Post)}
Reading between the lines of what you did not specify, it therefore seems to appear that in the programme, at the end of the movement order, there is an order to remove power and switch off the pulse modulation. if this is the case, it is obvious that the motor then remains free. If the position is to be maintained at the end of the movement, the motor current modulator, which on the PLC side is controlled via the MC_Power method, must not be interrupted. Another possibility is that in the motor drive settings, the standstill torque current is set very low or zero and without position monitoring. You have to check this via the servo motor drive.

Post by abrarsk on SysCom Library Usage ^{CODESYS Forge talk (Post)}
Hello all, I am facing issues with using SysCom library. With SysCom23 library things were simple but since we are migrating to 64bit systems, I am writing a Porting program. With SysCom23, opening the comport was as simple as providing the ComPort no. which returns the Handle as a DWORD. dwHandle:=SysComOpen(Port); But the new library is a bit different. It is asking for 2 input parameters to open the Com Port - Port Number and POINTER to RTS_IEC_RESULT IF hCom = 0 THEN hCom := SysComOpen(ComSettings.sPort, ADR(pResult)); How should I use the RTS_IEC_Result? I can find RTS_IEC-REUSLT under SysType2Interfaces of SysCom library. Also, can someone give me a general understanding of this RTS_IEC_REULT and RTS_IEC_HANDLE, etc.?

Hallo … ich verwende: SoftMotionLight im Positions-Mode Ethercat-Bus Servoverstärker: Metronix BL4104-C . MC_HALT_SML funktioniert nicht zuverlässig (Achse fährt manchmal zu weit oder bis zum Softwareschalter) Ich habe festgestellt, dass intern beim Aufruf von Positions- auf Velocity-Mode umgeschaltet wird - und dann wird wahrscheinlich intern auf Drehzahl 0 abgeregelt. Kennt jemand dieses Problem? – der Wechsel der Betriebsart ja ist nicht verzögerungsfrei! MC_STOP_SML Der Baustein hat keinen Eingangsparameter "Deceleration" Die Achse stoppt und bleibt im Positions-Mode. Aber die Verzögerung ist nicht wie beschrieben: nicht "Objekt 6085h: quick_stop_deceleration" - sondern "Objekt 6084h: profile_deceleration" - aus zuvor aufgerufenem MC_MOVE_ABSOLUTE_SML Ich wäre dankbar für jeden Hinweis Gruß Bernhard

Post by eguerra on Error in ScriptingEngine Docs - create_pou() ^{CODESYS Forge talk (Post)}
In the ScriptingEngine documentation there seems to be an error (or missing information) in the ScriptIecLanguageObjectContainer part ( https://content.helpme-codesys.com/en/ScriptingEngine/ScriptIecLanguageObjectContainer.html#ScriptIecLanguageObjectContainer.ScriptIecLanguageObjectContainer ). The description of the function create_pou() doesn't specify the correct arguments requested, it only says create_pou(type: SpecialPouType) and a script using the documentation definition of the function will raise an error. I tried passing the function arguments similar to the ones specified for the create_dut() function and it seems to work fine: create_pou(name, PouType) , name : str UPDATE: The offline help has the correct definition IExtendedObject<IScriptObject> create_pou( string name, PouType type = PouType.FunctionBlock, Nullable<Guid> language = null, string return_type = null, string base_type = null, string interfaces = null )

Post by installwhat on IDialogOpenedListener ^{CODESYS Forge talk (Post)}
Why do you develop things like this? The workflow should be highly dependent on autocomplete, then if that's not super obvious browse to definition and everything is made clear possibly with the checking of a few types. The nature of how things are done makes me think these libraries aren't developed for general use and are actually internal or for partners. The example projects include objects that don't appear in autocomplete and then lead nowhere obvious when browsing. Do you consider developer workflow when creating these libraries? Are some libraries really for public use such as Visu Utils and others not? If so which? It's really hard to tell.

Post by trusty-squire on parker servo and position ^{CODESYS Forge talk (Post)}
@gepert, When you say "I do not turn off power", are you saying you don't power off the drive, or you don't turn of the MC_POWER function block? I read your statement as you don't kill actual electrical power. MC_POWER should stay enabled. @Gustavo, not related to problem at all, but when you say 1.6 Nm is only enough torque to unscrew a loose bottle cap, I think that's a bit low. A quick mental math I use is 1 Nm is almost the same force as 1kG applied to a 10cm wrench. So 1.6kG applied to a 10cm wrench is still not a huge force, but more than enough to be felt if trying to turn the shaft by hand.

Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Post by gilbertamine on Comparing Arrays of structure ^{CODESYS Forge talk (Post)}

My structure is define like this : TYPE Positions_T : STRUCT PosX: DINT; PosY: DINT; PosZ: DINT; END_STRUCT END_TYPE I have multiples Var : ARRAY [0..220] OF Positions_T, that I need to compare quickly. I don't really want to do a Loop that goes by every 220 points and compare each one of them so I was wondering if there is another way. I came accross the MEM.Compare function, but it require to know the size in Bytes of the memory, and I don't know how to do that... Has anybody an idea on how to do the comparing easily ?
