Post by ryusoup on 'keep last value' option in CODESYS EtherCAT ^{CODESYS Forge talk (Post)}
Hello, I’m using CODESYS EtherCAT Master on a Raspberry Pi controller with several remote I/O modules. I’m facing an issue where the input values from the remote I/Os drop to 0 when a connection error occurs. Is there a way to configure a “keep last value” behavior (i.e., hold the last valid input) instead of defaulting to 0 on communication loss? Best regards,

256MB for the protocol yes, but the default value for this library parameter limits the library to 6kB per task scan.

... you say 1.6 Nm is only enough torque to unscrew a loose bottle cap ... This the the value of torque: from 1,2 Nm to 1,4 Nm that is cosidered acceptable for an old people. 1,6 Nm the torque considered acceptable for general use caps.

is your pointer set to the correct visu client? set a breakpoint in your client iteration and step through the active visu clients like programming system, targetvisu, webvisu,... and check the last usage value of each client

First of all you need to enable "Use unicodestrings" in the Visualization Manager. This function returns a pointer to a WSTRING (not STRING). To get this wstring value, do something like this: VAR myWstringVariable : WSTRING(255); END_VAR myWstringVariable := myResult^; // this is dereferencing the pointer to the WSTRING.

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.

Should work by using the property Dynamic bitmap - Bitmap version. Change the value of the variable you linked to this property after you updated the image. See: https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_image.html

Same for me. I have problems with UAExpert too. Can't see the Current Value of Enum and can't control. Did some Tests with Python opcua library. Not working with the communication manager so far.

Hi, unfortunately, in Softmotion you have only access to the combined fraction - the scaling factor from user units to motor increments. It can be accessed using MC_ReadParameter with parameter number 1054. increments = user_unit_position * fScaleFactor

Update as of 2025: This function (IECStringUtils.FormatDateTime) doesn't make any sense there isn't any parameter that accepts a Date_Time value. I have no idea what's purpose even is. I am going to use StuSprintf from the StringUtils library for this purpose.

Hello. I'm trying to create a Parameterized Property(CDS V3.5 SP21) to avoid copy-pasting code for processing array elements. I can't seem to get any result. Perhaps I am making a mistake with the syntax. None of the declaration options below are accepted by the compiler. If you know and use them (Parameterized Properties) in your work, please let me know. Thank you in advance. Option 1: PROPERTY <property_name> : <data_type> VAR_INPUT <index_name> : <index_type>; // One or more index parameters are declared here END_VAR</index_type></index_name></data_type></property_name> GET Code that uses <index_name> to return a value END_GET</index_name> SET Code that uses <index_name> and the implicit variable <property_name> to write a value END_SET</property_name></index_name> END_PROPERTY Option 2: PROPERTY <property_name> (<index_name> : <index_type>) : <data_type></data_type></index_type></index_name></property_name> GET Code that uses <index_name> to return a value END_GET</index_name> SET Code that uses <index_name> and the implicit variable <property_name> to write a value END_SET</property_name></index_name> END_PROPERTY

Hi, i guess you want to make a hour counter. You need to store the measured value. Try to use a retain variable, but need a graceful shutdown, or save it your self. see https://forge.codesys.com/forge/talk/Runtime/thread/278e325579/ Succes.
