Post by totorovic on IO-LINK Package - new license model ^{CODESYS Forge talk (Post)}
Thank you for your answer. Finally I don't confirm that it used to work before. It seems that the IO-link Package is needed is you want to configure the network, but you don't need it if you use generic IO-link devices.

Post by paulg on CODESYSControl_User.cfg - link to documentation? ^{CODESYS Forge talk (Post)}
Is there somewhere in the Codesys help files that generally details what configuration options are available for this file, and what details it logs regarding the configuration file? Or is that going to differ by libraries being used? Thanks!

Maybe your question makes sense but I don't see it. Maybe you should rephrase and add a lot of detail

I'm having the same issue.I think it may be something related to the device adress that changes depending on the network i'm using, but now i don't have access to the one i used while setting my user. Did you find any solution for this?

your device in the device tree is Pi 64 online you have Pi MC (32bit) - update device in the device tree to Pi MC then it will work.

Post by mp9876 on Problem using MeasureFrequence FB ^{CODESYS Forge talk (Post)}
Hi everyone, new at Codesys and PLC programming in general. I am using Codesys Win V3.5 SP20 I would like to measure an encoder's frequency output (obtaining that pulse train from Factory IO) and intended to use the MeasureFrequence FB (Intern/CAA/Utilities/CAA Mathematics/3.5.19.0). As mentioned in the title what I need to measure is low frequency, such as lower than 40hz (a cycle every 25mS) or so; I could even go lower frequency if required as this is for test purposes) therefore I am not expecting problem measuring a low frequency with that FB The library in question appears to be installed as I can retrieve it from the Library Repository. I can also see it from the Device's Library Manager. Problem arises when I am trying to instantiate this particular FB. I go like this: VAR MeasF:MeasureFrequence; END_VAR Please note that as soon as I start typing the "MeasureFrequence", the MeasureFrequence comes out as a viable option in auto-typing; seems to indicate that the FB is recognized somehow. But there is no way I can compile this as it comes back with the following: C0046: Identifier 'MeasureFrequence' not defined. Tried to rename that to ABC instead of MeasF; same issue. Possibly that the library is not properly installed ? Placeholder ? I would greatly appreciate a bit of guidance if possible. Thank you and regards, Mike

You never stay in a method. You need a block to do that. Something like: VAR button:BOOL:=FALSE; count:UINT:=0; END_VAR IF button THEN //read pressure count:=count+1; IF count>1 THEN button:=FALSE; count:=0; END_IF END_IF

I have now and it works. I had the idea that it had something to do with codesyscontrol.cfg, but where can I find a description of all the things you can set in codesyscontrol.cfg and its syntax?

Instead of using scaling of 150%, can't you adjust your diplay resolution (Windows+i keys, then go to System > Display settings)?
