I use fbMsSQL_compact(FUN) of the MySQL Library to write data to the database. There is no problem when writing data using only fbMsSQL_compact(FUN). However, when I try to write data obtained using SysProcessExecuteCommand2 to the database using fbMsSQL_compact(FUN), an error message "Dest server on ip address:xxx.xxx.xxx.xxx and port:1433 is unreachable" appears and writing is not possible. From what I have researched, it seems that writing is not completed in one cycle of fbMsSQL_compact(FUN), and when SysProcessExecuteCommand2 is executed first in the second cycle, the work done in one cycle of fbMsSQL_compact(FUN) is reset. Could you please give me some advice?

For anyone confused with the process visit this link (the bottom section about creating a .pfx file) https://content.helpme-codesys.com/en/LibDevSummary/certificate.html#import-of-client-certificates-with-private-key. I solved this problem by creating a .pfx file and importing it into the security store under 'Own Certificates'(must have SP18 or newer to import .pfx). I used a gitbash shell to enter the openssl command that created the .pfx file. Once you import the file, in your TLS context, set your 'sUseCaseName' to be the same as the name listed in the 'Information' column of your imported certificate. This did it for me

Hello, I'm trying to connect with a Wago TP600 HMI but without success. I'm using codysis 3.5 SP19 patch 7 (SP20 block all the time) and the official wago package is installed. However, when I scan and select my device, I get a message saying that the device doesn't match the project's device object with the possibility to update the device (as shown in the attached picture). however, after choosing to update i got a message that the device is not found. I've tried with a new empty project but the same results. do you have any ideas? Thanks.

Hello everyone, I’m trying to understand if it is this way or I can change it. I’m making a PLC code and visualization screens, the ideia is to operate via webvisu some controls. So i made a code, made some screens and when i try it in my web browser, first it asks me to insert te user and password of the wbm/runtime of the plc (user: admin, password: wago by default), then i can acess my screens but I have to login again with the user and password that i created in the visualization user managment. My question is: is there a way to disable this first login to the visualization screens (webvisu)? Or create another user/password for this first screen? I have a PFC200 and a Edge Controller, both are working the same way. Thanks in advance Thanks

After this being done and if I am forced to change any values or change any code in the current project, another compilation will be freezed. This problem can be solved if pressed Build/cleen or cleen all. There is another method to solve this; if project is loaded with excluded object (Alarm Configuration), repeated compilations will be done well.

Hi, I'm currently reading and writing several registers with a Modbus TCP server as a subdevice of a Modbus TCP Client. If I read and write cyclically, there are no issues. The problem is this: I see there is also the option to write by "Application", which I would like to use. However, I don't know With the Modbus RTU client, I see there is a trigger variable, xTrigger, to trigger the writing tasks. However, I can't find any such trigger for the Modbus TCP Client. Does anybody know how to implement the trigger behavior for the Modbus TCP client? In particular, I struggle to find the exact "trigger" variable. I'm running Modbus Client version 4.4.0.0 Thanks in advance!

Hi, I tried posting in the discussion for the HTTP Client example but perhaps that is not monitored? I have been using http client successfully for approximately 12 months, however in recent weeks I have begun to get TCP_INIT_ERROR when attempting to communicate. The only resolution seems to be power cycling and then the connection begins to work again for a time. I am not aware of any changes to code or libraries between working ok and now. Cold reset does not resolve, only power cycle. It seems the error from NBS.TCP_Client is 6002 which I think is invalid_addr However the address is the same when working and not working?

Post by adaml on ScriptEngine - execute "Export -> Bootproject and firmware (SD Card)" from python

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

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!

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.

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'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.

Or am I misunderstanding the way the library communicates with the drive?

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.

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.

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.?

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.

@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.
