Post by bruceae on Ethernet/IP Scan ^{CODESYS Forge talk (Post)}
Hello, I have a robot configured as a Generic Ethernet Module under Ethernet/IP Scanner. I can not see the change of state of the outputs coming from the robot on the codesys side in real-time. (The robot has it's own internal program that would changes the values of remote outputs 0-3 off and on). Also when I send data down to the inputs of the robot it doesn't transfer over as expected. As an example I'll send to the robot's input bit 0 a value of 1. It doesn't see that value change. However, when I write that input bit 0 back to a value of 0, the robot changes state and shows a value of 1. And if I change the state of a different bit, the other bits update properly, except for the bit that I changed. Any advice would be greatly appreciated, and if anything else is needed let me know.

The util.RAMP_INT and util.RAMP_REAL from Codesys have an input for the start value. What is the advantage of this OSCAT ramp instead of the Codesys util lib?

Post by umair on Code for reading 4 address to get 1 value of sensor (Ethernet IP) ^{CODESYS Forge talk (Post)}
Hi all, I want to ask, how do I write code to read multiple address for Ethernet IP communication protocol? Because this multiple address will produce one reading of a sensor that I am currently using. I want to read the value of the sensor. https://global.discourse-cdn.com/business6/uploads/wago/original/1X/7a79f4ad7ce474b9383b8550356d984defd9f3a0.png The addresses are in Byte. The 4 addresses are 89,90,91,92. Thanks in advance. Best regards, Umair

Post by swol on HTML 5 - Controls -> Change Content-Security-Policy settings ^{CODESYS Forge talk (Post)}
Sorry for being late to the party... so it is not possible to use the webbrowser tool to display external websites in a visu anymore? As it is not possible to simply "adjust the ContentSecurityPolicyIncludeTrustedOrigins setting in the automatically generated webvisu.cfg.json file" as stated in the docs? We need to display data read from a Raspberry Pi (part of our computer network) in our webvisu. We used to do it by entering the Pi's IP address as the URL variable in the webbrowser element but now (I don't know since when, I'm new on the job) "The page’s settings blocked the loading of a resource (frame-src) at 'IP address' because it violates the following directive: “default-src 'self' 'unsafe-inline'”. What are the options for displaying the data?

I think more information is needed to help solve the issue. Can you list the exact steps to reproduce the issue? What version of Codesys are you using? Did you add a persistentVars object to your project? I would recommend browsing all instances of the retain variable to see all possible writes to the variable in question.

Hello everyone, I was just wondering if anybody knows if there's a way to pull the string name of the current visualization without using the current visu variable. I'm working on a project where we don't want web clients to change the current visualization on the HMI of the machine. Thanks!!

Hi I need to update by software some structures in my datasource, i found this example: https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_update_data_interface.html it seems that because i use complex variable structure i need to use UseDataExpanding() instead of use data, the question is how to get an instance of IDatasourcesMgr3 i have the global variable g_Datasources is instantiated automatically

Post by imdatatas on The default ramp type selection in SoftMotion V4.18.0.0 is Quadratic ^{CODESYS Forge talk (Post)}
Dear @gseidel, Thank you for your clarification. I fully agree that the quadratic ramp type may have certain technical advantages. However, the main problem is backward compatibility and consistency across projects. In many automation projects, application developers rely on the fact that creating a new axis object will behave exactly the same way as in previous versions. With SoftMotion V4.18.0.0 and later, if an application developer adds an axis and overlooks the changed default, the motion function blocks behave differently than expected. In particular, since the Jerk value in SM3_Basic function blocks is ineffective in trapezoid ramp type, users are accustomed to leaving this parameter empty in their projects. In many existing projects, this variable has not even been assigned. When the default is changed to quadratic, the Jerk parameter suddenly becomes relevant, which can cause errors or unexpected behaviour in the field. From a user perspective, a default setting should always be the “safe” and “expected” option, while alternative options (like quadratic) can be selected manually if desired. Keeping the default as trapezoid ensures compatibility with existing projects and prevents unexpected issues, while still allowing users to benefit from quadratic ramps if they explicitly choose so. For these reasons, I kindly ask you to reconsider making trapezoid the default again. This would significantly reduce the risk of unexpected behaviour in future projects while still preserving the advantages of the quadratic ramp type for those who actively select it. Of course, the final decision is entirely at your discretion. Best Regards, imdatatas

Post by viksym on How to get the motor scaling value from code ^{CODESYS Forge talk (Post)}
If anybody finds this in the future, I managed to do it like this: scalingValue := EncoderPulseCountPerRev / ABS(AxisName.fScaleFactor); No need to use MC_ReadParameter as I am able to read this value directly from the axis object. Using an absolute value of the fScaleFactor is there in case the axis is set as inverted, in which case it would be a negative value. I was not able to figure out how to get EncoderPulseCountPerRev programatically, but since all my servos use an encoder with pulse count per revolution of 16#800000, the final equation looks like this: scalingValue := 16#800000 / ABS(AxisName.fScaleFactor);

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
The way I usally tackle this is by syncing only words (then you are able to use the FB above). If you then want to write a Boolean simply type it like this. Value[1].0 := Bool1; Value[1].1 := Bool2; Value[1].2 := Bool3; Uints have the same number of bits than a INT/WORD so these ones will work as well (they are only represented diffrently). A Real will work but you will loose some infomration in the conversion. If you want to keep the information you can convert 2 words to a float with a function (for example with the IEEE-754 standard) . In this way the syncing to the server is very simple and in the Codesys Program you decide what part of the word you want to use.

Post by dogulas on numeric text box control ^{CODESYS Forge talk (Post)}
Ok, this is how I made a numeric text field: use a Text Field properties -> Texts -> Text := %f (or %d or whatever you need) properties -> Text variables -> Text variable := (your numeric variable) properties -> Input configuration -> OnMouseDown -> Configure: Write Variable Input type := VisuDialogs.Numpad Use another variable (your numeric variable) Min val Max val etc. Please tell me there is an easier way to do this.
