You could try with "iMovementType" member of AXIS_REF_SM3 struct. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/DriveInterface/AXIS_REF/AXIS_REF_SM3.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/DataTypes/DriveInterface/SMC_AXIS_TYPE.html

Post by mecmag on gear over gear (2 masters,1 slave) - how to do it?
CODESYS Forge
talk
(Post)
Hello, i need to create an application that uses 2 masters, with 2 different ratios, and it outputs in one single slave. I explain better: Imagine axis A, B and C. -Axis A is the slave. -Axis B is master of A, with a specific ratio. -Axis C is master of A, with a specific ratio. the result motion from B and C should be executed by A, proportionally in position and ratios from B and C. With standard softmotion libraries (MC_...) it is not possible (i couldn't) because it is allowed only one master with its ratio. I have made a similiar application in past, using MoveOverGear in order to synch gears before engage. Instead this time, i need to do a gear over gear application, using 2 different masters. The position have to be the sum of both masters (considering their ratios). Any clue about how to do it? Or were to find some FB that can do it?

Please check the attached snapshot. I am converting an int to real and storing in rVlv01_SV and then scaling the value using LIN_TRAFO. In the bottom Status Bar of Codesys, both RUN and SIMULATION are visible. When I enter value 100 as input to INT_TO_REAL instruction and press Ctrl-F7, the value can be seen at the input but the logic seems not to work. I searched for help but could not find anything relevant. What could be the reason. Codesys ver3.5.11 svn

CODESYS Forge

(Post)
The probelm arises for the B&R T30 panel after updating Codesys from 3.5.17 to 3.5.19 patch 5. We have to use 3.5.19 for other reasons so we cannot downgrade the version. The scaling problem only exists for the B&R 6PPT30.0702.20F025 panel, the B&R T50 panel and a esa lumia panel work. When we choose a fixed resolution it looks also good, however we also want to support the esa lumia panel with a different resolution. The images show the anisotropic and isotropic option. In the anisotropic option it scales the hight correctly but not the width and in the isotropic option is scales both hight and width false, it also does not start in the top left corner. Does someone have any suggestion why it does not work anymore with the new codesys version and are there workarounds? I added all versions with visualization packages as an image, visuElems is 4.4.0.0.

Post by mahmutbeyaz on Create a Motion Profile
CODESYS Forge
talk
(Post)
Dear All, I hope first to get notice and somebody answer my question. How can I create a motion profile with the axis following it (once or periodically)? As my research shows, Schineder has a UI-based (Motion Sizer) program that helps create a motion with different configurations, which is Codesys-based. I need to create a motion profile based on position, changing the speed. (i.e., 0-300mm moves with 300 mm/s, 300-400mm moves with 500 mm/s, 500-800mm moves with 1000 mm/s, and 800-0mm moves with 2000 mm/s). MC_PositionProfile does it time-based, which is not working for me as the axis may not stabilize the position in time, which may cause a big failure in the system.

Hi, Softmotion Robotics does not support tracking in/out to dynamic coordinate systems with relative movements. Is MC_MoveLinearAbsolute an option? See SMC_RELATIVE_MOVEMENT_TRACKING_CS in https://content.helpme-codesys.com/en/libs/SM3_Error/Current/SM3_Error/SMC_ERROR.html Concerning the other error: Do you use any motion function blocks of SM3_Basic to move a single axis of the robot in your application?

most important information are missing: Which CODESYS Version? Which runtime version? Which plc type (manufacturere).. Not all plc manufacturer already support application based licenses. From your pictures I see you have activated 4 axis Motion (which is an applications based license type) does only work on plc's which do support this.

Post by mubeta on Some 'pathetic' errors in SoftMotion program
CODESYS Forge
talk
(Post)
Yes, this is the error the sometimes show up. What make me crazy is the fact that it happens randomly and not each times. I know very well where the problem is, in wich one program row it's located. For each actions of the state machine I have all events recorded with log on text file. it is not problematic for me to find the application point of the fault, but I need to understand why occasionally and for no apparent reason, switching the state machine and thus changing the motion FB, sends the axis into failure (but only occasionally). 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. 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).

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 trusty-squire on Confused by dwIpoTime input for SMC_Interpolator
CODESYS Forge
talk
(Post)
Hi, Learning Codesys CNC, and I am confused by the dwIpoTime parameter. I have a basic demo application, using SMC_Interpolator feeding into SMC_TRAFO_Gantry2Tool2, which then sets the position of the x/y SM_Drive_Virtual axis. I also have a C axis which revolves the tool, which is controlled using a simple tangential angle calculation SMC_CalcDirectionFromVector. The GCode I'm using has feed/accel set at 500. The axis configuration limits are well above that (2000). What's strange is that, when I run the simulation, the feed speed changes drastically when I update the variable dwIpoTime. The larger the number, the faster it moves. What's going on here? The documentation only says "This variable has to be set for each call. It represents the cycle time in ΞΌsec." Why does it change the feed speed I'm seeing the in simulation? What is a good number to use? The example I was looking at set it at 5000. Screenshot attached.

Hello, I'm coming from Siemens (TIA) world and currently learning Codesys. I'd like to know if there is an option to add external txt file with ST code for creation of a function block and then use this file as a source file from which FB will be generated? For example, in TIA, there is an option add external source file to the project structure and then use option "Generate blocks from source". This would create a FB. Does Codesys have something similar? This external source file would look like this: FUNCTION_BLOCK Scaling VAR_INPUT x, k, n : REAL; END_VAR VAR_OUTPUT y : REAL; END_VAR VAR END_VAR y := k*x+n; END_FUNCTION_BLOCK

I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used. Codesys PLC (GVLs) |Profinet | |--PNIO-node-1--| | | AIO, | | DIO, | | CNT etc. | |--PNIO-node-2--| | | AIO, | | DIO, | | CNT etc. Ideally I think of a configuration through yaml/xml-files (the assignment/linking of the profinet nodes towards GVL-variables in the PLC as well as scaling, channel configration etc.). Would be grateful if someone could suggest library/-ies that can handle the following: - Verify what IO is connected to a device/node. - Hot-swap/assign link for IO towards GVLs, either automatically or through a HMI.
