Post by darwin03 on Mismatch between coordinate monitor and actual motion using SMC_GroupJog2, MC_MoveLinearAbsolute (6DOF) ^{CODESYS Forge talk (Post)}
Dear Georg, Thank you for your explanation about the axis scaling. I checked the scaling of Joint6 and corrected it so that one technical unit equals one angular degree. However, I am now facing another issue. When I move all axes to zero position and then try to use SMC_GroupJog2 and MC_MoveLinearAbsolute, I receive the error SMC_CP_CONFIGS_DIFFER I already tried moving each joint manually to different positions before executing the motion command, but the error still appears. Could you please explain: What exactly causes SMC_CP_CONFIGS_DIFFER Thank you very much for your support. Best regards, darwin03

Post by baotthitawat on Why Structured SCADA Documentation Matters in Modern Industrial Systems ^{CODESYS Forge talk (Post)}
Modern SCADA development is no longer limited to monitoring dashboards and PLC communication. Today’s industrial systems often require: Cloud architecture Web & mobile SCADA API integration IIoT communication Alarm management Scalable deployment workflows One challenge in many projects is that deployment knowledge is usually scattered across multiple documents, configuration guides, and troubleshooting references. As systems become more connected, engineers need a more structured learning approach to reduce deployment time and improve maintainability. The ATSCADA Training Book is an interesting example because it organizes the ecosystem into a clearer roadmap covering: SCADA architecture Driver & OPC communication Web visualization Mobile applications Cloud & IIoT systems Troubleshooting & maintenance I think structured technical documentation will become increasingly important as industrial automation systems continue evolving toward larger and more connected environments.

Post by baotthitawat on SCADA Systems Are Becoming Easier to Integrate With Modern Applications ^{CODESYS Forge talk (Post)}
One thing I’ve been seeing recently is that more industrial systems are starting to expose realtime SCADA data through APIs instead of keeping everything isolated inside the local monitoring software. This makes integration much easier for cloud platforms, mobile dashboards, AI analytics, and enterprise applications that need realtime industrial data. Instead of exporting reports manually or building complicated middleware, APIs allow external systems to access SCADA data directly in realtime. I think this becomes especially useful for applications like wastewater treatment monitoring, where operators need better visibility into alarms, equipment status, and operational conditions across different locations. Feels like modern SCADA is slowly evolving from a standalone monitoring platform into part of a larger connected industrial ecosystem.

Subject: Curtis 1229-4105 CANopen (CiA 301 / CiA 402) Hello everyone, I am developing a battery-powered industry vehicle using a Curtis 1229-4105 motor controller together with a Siemens S7-1200 PLC and an HMS (Ixxat) CANopen Master. I am looking for someone who has practical experience with the Curtis 1229-4105 CANopen implementation. I would appreciate your help with the following questions: Does the Curtis 1229-4105 support only CANopen CiA 301, or does it also support CiA 402? Is an EDS file available for this controller? Is the CANopen Object Dictionary available? Has anyone successfully communicated with the Curtis 1229-4105 from a Siemens S7 PLC or another CANopen master? Are the CANopen PDOs and Object Dictionary based on the standard CiA profile, or are they Curtis-specific? Any documentation, examples, or practical experience would be greatly appreciated. Thank you very much.

Post by pernockham on Gateway in China - "Gateway not connected" ^{CODESYS Forge talk (Post)}
I think I understand my problem. They are most probably related to configuration of the network. When I use DHCP for the unit to my router it all works. However when using static IP I have not managed to reach functioning state. Trying to replicate the situation on my desk. Having a static IP on the "debian host" and a connection to my computer which then routes traffic on to internet. I have entered settings for gateway and netmask. I can ping from my "debian plc host" to internet and also do "curl google.com" so traffic seems to find its way through and back, still "Automation server" will not find the gateway. Any hints how a manual configuration should be done? Is it possibly a "firewall" issue of my "normal router"? Thanks for any help! Per

Post by timvh on CPU + EtherCAT redundancy ^{CODESYS Forge talk (Post)}
It works well with two Wago 750-8210's. I helped a few customers setting this up. But it should work with any device which can control EtherCAT I/O, is real-time and has sufficient network interfaces. Two network adapters can be used to create a redundant EtherCAT network (you need 2 additional switches for this). The other network adapters can be used to interconnect the 2 PLC's (synchronization). We noticed that if you exchange variable lists that there could be some issues if you have long lists. So what we did is use a SoftPLC on a server that contains all the settings which continuously sends network packages (GVL sender) and which is received by both PLC's (network receiver). Switching over is done in milliseconds. The bus doesn't notice the change-over. EtherCAT communication works flawlessly.

The licence has been activated with a computer Name, but the guy who did it make a mistake in the name, so he changed it after to have activate the licence. I think this has created a second container. The licence is actived on the other container.

Post by timvh on EXCEPTION [watchdog] how to find position cause ^{CODESYS Forge talk (Post)}
Monitor what your current cycle time is (in the Task Configuration when you are online). If this is sometimes close to 200ms, then change your code (e.g. limit the loops, or prevent copying a lot of data between objects). Or just set the Watchdog time (or sensitivity) higher if you don't care that it sometimes takes longer than 200ms. If you want to find out which objects in your application consume the most time, then buy a PDE (Professional Developer Edition) license. With this you get a license for the Profiler. This can help you a lot to find the root cause, because it will create a nice overview of all objects, their calls and the time (percentage) it takes to execute it.

Post by konstantin on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Hello, one of the projects I work on is about a racetrack collator with two independent belts on it - two different servo motors. Both motors share the same mechanical frame and there is a train on a belt that collects items from the input conveyor. The way the motion is performed is the following - there is a virutal master axis and both real axis are synchronised with different cam motion profiles. The problem is when an STO is triggered on any of the slave axis, the synchronization process starts from position 0 of the slaves. How can I force the slaves to retain their current position until the master passes their position? Then the slaves should catch up with the master according to the profile, the slaves should not start synchronization from 0 position. Best Regards Konstantin Kolev

Post by konstantin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
Hello, basically the i950 drive support CiA402 Basic and CiA402 Advanced modes. I attached pictures of both mode supported functions. It also support CSP, VL, CSV and CST modes. It seems the homing mode is in CiA402 Advanced mode but how can you not have the homing mode in both modes? It is a vital part of any servo system. If I use the SoftMotion standard demo mode, I can move the servo absolute and relative but cannot home it. But in SoftMotion Light mode, I cannot execute any motion function. Here is the official manual for i950 servo drive - i950 Documentation Best Regards Konstantin Kolev

Post by gseidel on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Dear Mr. Kolev, I'm not sure I understood correctly. But this is my take on your question: When the STO of the slave is triggered, store the current master position (e.g. 225 units) After the reset of the slave error, call MC_SetPosition on the virtual master and reset it to the stored position (225 units) Optionally, before MC_CamIn is restartet, move the slave back to the slave position corresponding to the stored master position. (If you do this, no ramping in will be necessary) Restart MC_CamIn, with absolute master position and absolute slave position. Choose the StartMode that is appropriate for your machine. Best regards, Georg Seidel

Post by gordonkeller360 on Escape character behavior for hex values in string -- what gives? ^{CODESYS Forge talk (Post)}
I have a program which sequentially places byte representations of characters from a string into an array. FUNCTION_BLOCK MoveBytesFromString VAR_IN_OUT abRxBuf: ARRAY [0..79] OF BYTE; END_VAR VAR testString : STRING := '$0A$R$L$TTesting,123...$94$86$0A'; iCount: DINT; END_VAR ---------------------------------------------------------------------------------------- // clear the buffer MEM.MemFill(ADR(abRxBuf), 80, 0); FOR iCount := 0 TO LEN(testString) - 1 DO // account for undesired null terminator of string abRxBuf[iCount] := testString[iCount]; END_FOR Escaped characters, like $T, $N, etc. work just fine, and so do their hex representation counterparts ($09, $0A, etc). However, when I put something like $94, I get a set of nonsense values... see image attached after one spin of the program. Could someone explain to me what is happening here? I'll continue to investigate...

Post by poliautomacao on Absolute movement controlled by an external encoder. ^{CODESYS Forge talk (Post)}
Hello, I made this configuration, I'm moving the encoder value to SM_Driver_PosControl.in.wActPosition. When I make the absolute movement of my PosControl axis, my physical drive axis rotates perfectly, but I noticed that the movement is not followed by the encoder. That is, if I hold the encoder and keep it in position 0, the PosControl axis makes the absolute movement of 314 mm and stops, which is strange because the encoder is at 0. Theoretically, the PosControl axis should accelerate to try to compensate for the movement error. I haven't yet achieved perfect functionality.

Post by jorenbeyl on library inside library ^{CODESYS Forge talk (Post)}
I am currently developing a library that contains real‑time data. To handle this real‑time data, I am using additional libraries called SysTime and SysTypes Interfaces. When I compile my library on its own, no errors occur. However, when I use this library in a project and compile the project, I get an error indicating that the SysTime data type is not recognized. This happens even though the SysTime library is visible as a dependency under my library. Does anyone know how to correctly include a library within another library so that the project recognizes the sub‑library without causing compilation errors?

Hallo zusammen, ich habe schon einige Zeit 16 DS18B20 am 1 Wire laufen ... auch die ganze Zeit stabil ... jetzt habe ich ein PWM Signal über i2c für eine Pumpenansteuerung zusätzlich in Betrieb genommen.. nur das Signal für die Pumpe geht über i2C ... 100Hz 10ms. Es läuft auch alles soweit ... nur fallen mir jetzt die Temperaturen in Abständen aus ... Vertragen sich die beiden Systeme zeitlich evtl. nicht so gut ... 1 wire extra task mit 200ms Prio 0 i2c task 10ms ... damit die 100Hz auch übertragen werden Prio 1 (Adafruit_PWM) Main Task 20ms Prio 5 Oder jetzt besser beides über i2c abrufen ... ist aber dann evtl. für die DS18B20 zu schnell ? Oder sind die 5V vom Pi jetzt zu schwach für beide Signale? Vielen Dank euch

Post by kurt9 on ReadWriteEEprom FB question ^{CODESYS Forge talk (Post)}
I want to programmatically write the alias address to a new EtherCAT slave when I plug it into my IPC EtherCAT network. I am looking at the ReadWriteEEprom FB and see that one of the elements is "pbyData". which is the pointer to byte that is usually set to 2048 bytes. Since I am setting the alias address to the EEprom only (EEprom address 16#0012), I would assume that what I am writing is 2 bytes only. Does the pbyData have to be specified as ADR(myArray) where "myArray" is the 2 bytes of the alias address? How is the best way to set this element of the function block? Thanks in advance

Post by alex-n on Problem with keeping up the distance between two axes ^{CODESYS Forge talk (Post)}
Hello. I have a task to synchronize the movement of two axes and maintain the distance between them. First axe makes equal steps by trigger using MC_MoveRelative function. The second one is standstill and after another signal should catch up the first one from its position to a specified distance and keep it. I've tried to use MC_Phasing and mostly it works. Second axis catches up the first and starts make step with it. But in one moment this axis can crash into the first and there is no clear connection as to why this is happening. It can work correct for a day or for a week.
