Post by stribor on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
if i only use it as input variable I won't be able to update its state within the visu object. Lets say i have real value as a property, i would like the slider object to display this value and also modify it.

I am using TargetVisu in my v3.5 sp20 p6 (64-bit) project. I see no control that will allow me to bind, edit, and display a LREAL variable. Am I missing a library? If it exists, why can't I see it?

Post by seweb on NTCIP ^{CODESYS Forge talk (Post)}
Hello everybody, In an upcoming project we are supposed to control a display board via NTCIP. Unfortunately, I have not yet found out whether this is possible with CODESYS. Are there any libraries for this in CODESYS? Best regards

Hello Tim, I am using CODESYS Visu V4.8.1.0. It works when I turn off the "Support client animation and overlay of native elements". But if I do that, dialog box moving and other options are also disabled so it is a bit problematic. Thank you for helping.

Post by jinlee on Dynamic I/Os Mapping ^{CODESYS Forge talk (Post)}
Hi guys, Recently, I am working at the Dynamic I/Os mapping feature in Ecockpit or Codesys v3.5. I have been trying the libraries. However, it looks like it will not work as I wanted. I want to build the PLC which can detect all the I/Os itself and from there, I can do something on these channels. For example, the current setup is one digital input card, one digital output card and one analogue input card. Then, I want to add one more card into the setup e.g. one more digital input. Then, wago screen can detect this and we can assign them to tasks for example to control digital output. May I know is it possible ? Kind regards

Post by tk096 on Motion FB Error ^{CODESYS Forge talk (Post)}
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?

Post by timvh on Library ENUM text representation in visualization ^{CODESYS Forge talk (Post)}
Probably the enum from the library doesn't have text support. In that case you need to add your own TextList to the application. In the rectangle you should use the property "dynamic text" to link this object to the textlist which you have created yourself and then link the text index to your enum variable.

Post by trusty-squire on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Just a stab in the dark, but you might want to check the Dynamic Limits (accel, decel, velocity, jerk) in the Codesys SoftMotion device configuration, as well as checking similar limits on your servo drive? Are you seeing any errors, or does the MC_SetPosition FB get marked as complete?

Post by gseidel on Dynamic target position tracking ^{CODESYS Forge talk (Post)}
Hi kporter, a more direct way would be to use SMC_FollowPosition to write the set positions directly to the servo drive. This FB has reacts on changes of the fSetPosition on each call, without a need for a rising edge on Execute. See https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html. Best regards, Georg

I'll have a look at this, thanks. Do you maybe know why the C-integration doesn't work? I'm just curious because it was still some effort to create all these files. Ending up with a meaningless error feels very unsatisfying to me...

I've tried the "updateComPortSettings" method on the slave device but it doesn't work and gives the "Modbus_COM_Port" an error. Can you tell me how you got this method to work? Thanks in advance for your help jérémy

Post by smartcoco on Dynamic object release issues ^{CODESYS Forge talk (Post)}
Dear, When I use "__NEW" to dynamically create the object "Object_1", and assign this object "Object_1" to another object "Object_2". At this point, I use "DELETE" to release the object from "Object_2". At this time, I cannot judge whether the object has been released normally through "Object_1" (in fact, the object has been released theoretically). Thanks for you help.

I have managed to change my dynamic visu table colors with the template for each column to dark like my rest of the webvisu background is. How ever the empty table (when not populated) and the table header stays white / gray. Is there same way to modify the colors of header and empty table?

Post by manuknecht on Maximum dynamic limits of MC_MoveLinearAbsolute and MC_MoveLinearRelative ^{CODESYS Forge talk (Post)}
Hello all I use an axis group with two linear axes in a kinematic system. Using MC_MoveLinearAbsolute and MC_MoveLinearRelative, I am trying to realise dynamic movements (set velocity: 1 m/s, set acceleration: 30 m/s^2) with the highest possible jerk, as I want to compare this with a movement with a trapezoidal velocity profile. However, my measurements show that the axes accelerate with a maximum jerk of approx. 800 m/s^3, even if the value in the function block was set to 10,000 m/s^3. I have already increased the dynamic limits of the two axes accordingly (Velocity: 5000 u/s, Acc-/Deceleration: 250'000 u/s^2, Jerk: 100'000'000 u/s^3, where 1 u = 1 mm), but this had no effect. I have checked the input parameters of the function blocks and the VelFactor, AccFactor and JerkFactor factors are all set to the maximum (value 1). Reducing the cycle time has resulted in a higher jerk, but as we are already working with a cycle time of 1 ms, there is nothing more that can be done here. The axes themselves are still a long way from drawing the maximum current, which is why I assume that this should not be a problem either. Are there other factors or parameters that influence the dynamic limits and therefore allow faster movements? The PLC I am using is a Raspberry Pi 4 and Codesys V3.5 SP20 with all libraries up to date. Thanks in advance Manuel

Post by drml on Array to String ^{CODESYS Forge talk (Post)}
If a size is not specified, CODESYS allocates 80 characters by default for a string. After 7 seconds, does your Json_string contain all of your 20000 key/values? Or is the result truncated to 80 characters?
