Post by timvh on CANbus issue ^{CODESYS Forge talk (Post)}
On a PC with the Control Win, this is probably related to the fact that the CAN drivers are not loaded. Go to the folder where your Control Win Configuration file is: - E.g. C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE - Open the CODESYSControl.cfg - Remove the semi-colon in front of the CAN driver you want to use (section ComponentManager). - Set the component ID to the next number in the list (e.g. Component.8) - Save this file and restart the Control Win.

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I have not gotten to the bottom of this yet no. I have double check that the variables are correct linked. When online with the program I can see the button and rung going true for the move instruction, yet it does not change. Forcing the bit in the program does change the value in Groov View. I am kind of at a loss here, especially since the other POU(For the pumps) does the same thing fine.

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Thanks for the advise, indeed, this was somewhat, what my intention was. I tried around again with EDSes and DCFs, anyway. It appears that the DCFs end up in a subfolder in the attach device dialog. Astonishingly, when attaching the DCF version I get a device in the device tree, where I can add a SoftMotion axis, whereas when I attach the device not in the subfolder, then I cannot. Further astonishingly, when looking in the CANopen parameters in supported profiles, "402" is listed in the case of the DCF variant, whereas in the EDS variant "0" is shown. Comparing EDS and DCF files I cannot guess, where the difference is coming from. I cannot tell either why I have always attached the EDS variant and apparantly never the DCF variant. As I am not in the lab right now, I cannot test if the connection actually is working. Thanks again, spiessli

Hi, I am trying to make my runtime support TargetViso on 4.12.0.0 runtime. First when I tried to install package I got error due to missing libraries that are generated through qt-base. After compiling and installing related qt lib when I tried to install the package, I didnt get lib dependencies error but I got another error: [ERROR] The installed QT Version does not meet the minimum required version 6.4.2. Please install version 6.4.2 or higher and try again. When I check Qt version I get the following response QMake version 3.1 Using Qt version 6.5.0 in /usr/local/qt6/lib. I tried with Qt version 6.9.0 but that didn't help. Any idea on what coudl be the reason. When I looked for codesys related processes the related libraries were included within environment.

Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
After some more digging I realized that I get an error on the PLC Logger saying PersistenceChannel: 150 (invalid type in data: SimpleLibrary). I suppose the issue could be found in the ConfigData, which is automatically generated and which looks like this: 1 9##83 SimpleLibrary#GVL.aMoreZeros.[1]#0#64512#15#0 <[2]#0#64520#15#0 <[3]#0#64528#15#0 <[4]#0#64536#15#0 <#0#64544#15#0 <[6]#0#64552#15#0 <<lrVar#0#64560#15#0 <strVar#0#64428#16#80 <uiDummy#0#64370#11#0 Perhaps the fact that the variable is stored within a library confused the compiler? I tried changing the PersistenceChannel parameters to xCompressTags := FALSE which changed the entry in the data file from _xCompressTags BOOL:TRUE _xCompressTags BOOL:FALSE but the actual content of the data file and also the config data did not change.

Post by mp9876 on Problem using MeasureFrequence FB ^{CODESYS Forge talk (Post)}
Hi everyone, new at Codesys and PLC programming in general. I am using Codesys Win V3.5 SP20 I would like to measure an encoder's frequency output (obtaining that pulse train from Factory IO) and intended to use the MeasureFrequence FB (Intern/CAA/Utilities/CAA Mathematics/3.5.19.0). As mentioned in the title what I need to measure is low frequency, such as lower than 40hz (a cycle every 25mS) or so; I could even go lower frequency if required as this is for test purposes) therefore I am not expecting problem measuring a low frequency with that FB The library in question appears to be installed as I can retrieve it from the Library Repository. I can also see it from the Device's Library Manager. Problem arises when I am trying to instantiate this particular FB. I go like this: VAR MeasF:MeasureFrequence; END_VAR Please note that as soon as I start typing the "MeasureFrequence", the MeasureFrequence comes out as a viable option in auto-typing; seems to indicate that the FB is recognized somehow. But there is no way I can compile this as it comes back with the following: C0046: Identifier 'MeasureFrequence' not defined. Tried to rename that to ABC instead of MeasF; same issue. Possibly that the library is not properly installed ? Placeholder ? I would greatly appreciate a bit of guidance if possible. Thank you and regards, Mike

Post by tyronnosaurus on ReceiveWatchdog FB not working on J1939 P2P PGNs ^{CODESYS Forge talk (Post)}
Hi guys. I've got a device that sends a status message over J1939 and a PLC running Codesys to receive it. This message uses a P2P PGN (as opposed to a broadcast PGN). Codesys can only read it if I mark the J1939_ECU as "Local" (see screenshot 1). The message is received correctly, that is not the problem. The problem is detecting if the message stops being received. Local ECUs have no Watchdog checkbox to detect if the message has been received in the last X seconds. In order to implement a watchdog, I've used a ReceiveWatchdog FB. The same code works well for any non-P2P message, but doesn't work for this particular P2P message I'm trying to monitor. Even if I physically disconnect the device, ReceiveWatchdog.xBusy stays True, and ReceiveWatchdog.xError never triggers due to a timeout error. Is there any caveat in the ReceiveWatchdog FB that makes it unable to monitor P2P PGNs in Local J1939_ECUs?

Post by george32 on Readable IO names ^{CODESYS Forge talk (Post)}
Hello Folks, I have a quite basic understanding of how PLC programming works. However I keep getting stuck on 1 problem I could not get my head around. The problem is as follow: I have a PLC with 60 IO (20 inputs, 40 outputs). Each IO is defined as a function block. Furthermore I have an external IO card connected trough a CanBus connection. This IO card has 4 analog input channels (USINT), 4 digital inputs (Bool) and 4, digital outputs (Bool) Because I have 2 different components which both has data have I made 4 arrays to store the data off every component in one variable. PLC_Input: Array [1..20] of BOOL; PLC_Output: Array [1..40] of BOOL IOCard_Input: Array [1..8] of BOOL IOCard_Output: Array [1..4] of BOOL Because the control and reading of the different in and outputs is done by a TCP connection I want to use some kind of enumeration or struct to give each index a name so that my main would be a little bit more readable instead of all the magic numbers. Also this would make my program more dynamic for the furter in case I need to changes some in the IO nummers. For example: pump is placed on the fysical terminal strip number place 54, which is the 3th output of the IO card in the program: if I am sending a message with value 54 I would like to control IOCard_Output[3]. If there is a solution or methode to get this done, I can eventually do the following in my main program: IOCard_Output[Pump]. I have tried the following: IOCard_Output[Pump - 51] with an enumration but this keeps raising an error I hope some of you could help me further with this problem. In gross lines: I want to couple all the different IO to a more readable name and this readable name should control the right Array index Thanks in advance, George

Post by muhq on Profinet connection to Siemens CP343-1 Lean (IO-Device/Slave) ^{CODESYS Forge talk (Post)}
Hi, I am quite new to Codesys and I try to do a Profinet connection to an Siemens PLC (315-2DP) with CP343-1 Lean Modul. I already configured the Siemens PLC, exported the GSDML. Then I added a new project in Codesys, added following moduls: - Ethernet - PN_Controller - Imported Profinet Device via GSDML importer When I start the programm everything looks fine but I always get the message "Stopped Profinet" and no data is available This is only for a small test. Therefore I start to do that on a Windows 10 with Development System. Later I will try to realize this on Raspberry. Ethernet Adapter is configured (192.168.1.1 / 24) Firewall deactivated WinPCap is installed S7-Station seems to be found ('fuadazenzitest') Can please somebody help me?

Post by tk096 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work). In general: - Motion function blocks have to be called until they report 'Done', 'Error', 'CommandAborted' or a subsequent motion FB with BufferMode=Aborting is started in the current cycle. - Setting the Execute input to FALSE will not abort any ongoing motion of the motion function block. For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. I think the error SMC_FB_WASNT_CALLED_DURING_MOTION is only a follow-up (and misleading) error that results from the axis not being in operational state anymore (bus problems). Is there an error 'regulator or start not set' in the device log before the error 'motion generating FB wasn't called for at least one cycle'? Which error does the respective function block (Halt.ErrorId) report?

Post by vernon-laurence on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
The simplest way to do this would be to add a bus coupler dedicated to the expansion IO. The EtherCAT network does not fault when modules connected to the expander are not present. In the image below, nothing below the red line is present in the network - with the network working correctly. In your "base" project, simply include all of the possible modules, and then plug them in as you add pumps to the system. I would also highly recommend against the use of direct addressing. There are other methods to accomplish this, including using the "Optional" checkbox for modules and explicitly addressing them. Although, this would require more upfront work to design the network, and some additional work each time modules were added. https://content.helpme-codesys.com/en/CODESYS%20EtherCAT/_ecat_edt_slave_slave.html

Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
Using SDO, I can read the EtherCAT mappings and offsets from various registers like 0x1c12, 0x1c13, etc. When I obtain registers mapped in the PDOs and various offsets, I could technically access directly to the statusword, controlword, etc., if they are mapped. I have noticed that on IoDrvEthercatLib.ETCSlave_Diag I can find pointers to the input and output buffers. However, although the input buffer can be easily read by referring to what has been obtained from the SDOs, it is not possible to write to the output buffer, as it is overwritten in each cycle by the data from the IOMapping task. Is there a way, knowing an instance of IoDrvEthercatLib.ETCSlave_Diag, to obtain the pointer to the first data in the IOMapping? The offsets are identical to those of the PDOs, but obviously the data is a copy. For me, the cleanest thing would be to access the pointers on IOMapping, for DS402a devices to retrieve the key data and point them to internal references. I need to know this as, having developed our own motion library, I would like to simplify the initial setup by eliminating unnecessary and nonsensical mappings that can lead users to unnecessary errors. In the current version that we have been using for years, we have to map everything manually. I would like to pass only the slave reference to the FB_init constructors and eliminate the mapping.
