I have the same error. It appears to be something in my project. An older version of the same project from a few days ago is fine.

Hello @eschwellinger, I installed the newer version of the installer, however the issue persisted. Do I need to do anything else other than updating the installer? Thanks for your help.

Post by ruben on DataSource not working ^{CODESYS Forge talk (Post)}
I had the same error. It took me a LONG way to figure it out, but in my case the problem was that I used LDATE_AND_TIME. It seems to be not supported, at least not in the Codesys version I used (3.5.16)

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
I am trying to implement a mechanism to send alarm SMS. For this, I have created an Alarm Class with a Notification Action which calls a POU. This POU implements IAlarmNotifiable making it selectable in the Alarm Class configuration. IAlarmNotifiable has an Execute method which is called by the alarm class. Now, I want to extract the alarm message of the triggered alarm. The Execute method comes with a VAR_INPUT itfAlarm: AlarmManager.IAlarm which supplies a method called GetMessage. The help text says: Returns the message text, that has been configured for the alarm. The result is a pointer to the buffer, where the message text is stored The type of the result is CharBufferPtr, and at some place I read that it can be interpreted as a pointer to string. But I cannot manage to extract the alarm message, all I get are numbers. I have tried the following: psAlarmText := itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^; sAlarmText := TO_STRING( itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^ ); So how do I get access to the alarm message as clear text? (In this case, "Larm 1")

Try setting up your project environment. You can do this under Project -> Project Environment -> Press Button "Set all to newest". You have set your compiler, devices, etc in this project to the newest available versions.

I'm not sure, but maybe you have to configure the 750-652 first with the WAGO-IO-CHECK software to set it in RS485 mode?

No, you can´t. I have only tried different browsers on my PC and then on my HMI device. Unfortunately the device´s browsers did not support pdf file as I needed so I had to switch to *.txt.

you need to switch to a realtime capable plc. Do not map variables, this will be done by the SoftMotion. And check the Ds402 parameters in the generic parameterview on the Softmotion Connector.

The green icon with an ! next to the device is concerning. Is the data type correct for the input, you are using a byte input but the description says string. Is there anything useful in the status tab?

Yes, green icon is there, this time I tried by enabling the device to always update variables but results are the same. I have attached the screenshot and eds file I am using.
