Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
Thanks for the response, as I've thought about this problem over the last month I began to suspect this was a problem with not being able to exactly represent .1 as a 32 bit binary number. I think I've found a work around by making the number an integer, then dividing it by 10 and storing that value as a floating point number. There is still an issue with the value not being exact somewhere in the 8th or 9th decimal place, but because I'm incrementing an integer value then dividing it, the error doesn't compound.

Post by jaspergain on Non-existing identifiers ^{CODESYS Forge talk (Post)}
Hello, I got a bit of a weird issue going on which is kind of annoying. So recently we switched a lot of Modbus IO to EtherCAT, as we were having issues with stability. All works fine, which is great. But sometimes when I change the program I get errors claiming that identifiers are not defined. Meaning I can't go online. See the picture below. I believe this is because some of these identifiers were used with Modbus, and they weren't properly removed/deleted? A clean all temporary fixes the issue, but it comes back again after a while of changing the code, and building. Any way to fix these non-existing required identifiers, or even find out where they are required? Thanks for the help in advance. Jasper.

Post by anlebr on Codesys Communication Manger - Required information model version exists in the model repository but is not found ^{CODESYS Forge talk (Post)}
Hi I am trying use the Codesys Communication Manager to set up an Opc ua server with a custom information model. As a start I am using the Boiler model available on Opc foundations github page. I am testing with a Wago CC100 and using Codesys V3.5 SP19 Patch 6. I get the following error: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://opcfoundation.org/UA/Boiler/ with a minimal publication date from 15/12/2023 but the device has only a model from 15/09/2021 installed. Probably the information model from 15/09/2021 is missing in the information model repository. The error message does not make sense to me. Should it not be “Probably the information model from 15/12/2023 is missing in the information model repository”? Anyway, both versions are available in the repository. How can I solve this?

CODESYS runtime version 4.9.0.0 for your Pi. ssh user should be pi. This is for RasperrPi Os 32 bit. If you are on RasperryPi OS 64Bit use Arm 64bit SL product as Runtime.

With this kind of motor nominal tourque I can belive that it can be moved very easy. 1,6 Nm is, for example, the torque required for unscrew a small loose cap from a bottle.

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Hello mates, I'm working with CODESYS V3.5 SP20 on a Raspberry Pi and I use "Raspberry Pi MC SL" as device on the project. I've installed the Control Standard L (multicore) license on a Wibu System usb-Dongle (cmStick/4.50) that already had another license from another vendor. I follow the online activation procedure from CODESYS documentation. Raspberry Pi has already CodeMeter installed for the other license. When I plugin the dongle on Raspberry and start the Runtime from Raspberry Pi Update in CODESYS I receive the message that I'm on Demo mode because the license is missing. I double checked that the license is activated in the dongle, through the WebAdmin of CodeMeter and the second license runs properly without any issue. I have already try to change the dongle from HID to MSD device and backward but the the Runtime cannot recognize the Dongle. I have also try to stop and start the Runtime through CODESYS without success. Is there anything else I can do to fix this issue?

Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
I have discovered a rounding error, either in Codesys or in my understanding of numbers. The attached ladder shows that when the up button is pressed the number increases by 0.1, when the down button is pressed number decreases by 0.1, after several button presses the number isn't equally divisible by 0.1. Have I discovered a bug or am I doing something wrong?

Post by kumareasu on Persistent variable storage ^{CODESYS Forge talk (Post)}
Is there any function function block which can store the persistent variable in HDD/SSD immediatley. My observation is that the persistent variable is getting stored when we shut down or restart the system (Windows+ CoDeSys RTE SL ). the persistent variables are not stored in HDD/SSD, if I power off the system without proper shutdown. Seeking your feedback.
