I'm no longer working with this PLC brand, but if I were you, I would try to stop all related Codesys services before the copy and restart them after that.

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
Solved it! The simple answer was to declare a variable as POINTER TO STRING and assign the GetMessage result to that variable. Then, the ^ operator can be used to extract the message as string.

The IoT library contains a Web Socket library. Maybe this provides your required functionality. See https://store.codesys.com/en/codesys-iiot-libraries-sl.html

If I remember well, first you need to delete the current version. Then clicking through the tree as indicated in the previous post, lets you choose the "outdated" libraries.

When you create a new POU be sure to choose "Ladder Logic Diagram" instead of "Ladder Logic" and you'll get all the additional toolbox items.

Are you using the Wago Runtime - please check the version information on scan. Either 6.x.x.x or CODESYS 4.x x.x SL Runtime- and always check the plclogger in such cases.

Hello You'll need to write a proper sequence to send, then wait for confirmation, and then move on to the next step. Use the CASE statement in ST. It's perfect for creating a sequence.

Hello, you probably fixed in this meanwile, but I think your problem comes from dependencies of other libraries. I see in the Project column of errors the "caa types extern" and "caa fb factory", that both have dependencies. Try to check there. Regards, Francesco

Post by tomast on Codesys and Siemens SINAMICS 20 modbus RTU "Response CRC Fail" ^{CODESYS Forge talk (Post)}
Hi everyone, I'm currently working on a project involving the control of 5 VFDs via Modbus RTU, this time using the WAGO 750-8212 CPU. So far, I've managed to make progress, but I've encountered an issue. While I can successfully read and write to all the registers I need, I consistently encounter a "Response CRC Fail" error when attempting to write the value 1151 to the STW register at address 40100. I'm able to set the frequency via register 40101 and adjust all other parameters using different registers. Setting STW to 1150 results in the drive ready boolean from the ZSW-bit being received instantly. However, the moment I attempt to send 1151 to register 40100, I immediately receive the "Response CRC Fail" error for all channels. I've also attempted to use combined control, employing Modbus for frequency control and starting from a digital input. Everything seems to function properly until I send the start command to the VFD. Interestingly, I consistently encounter the same error the moment I send the start command, regardless of whether I use register 40006 (high) or 40100 (1151). Could someone please assist me in resolving this issue?

Hi, you should have 'CODESYS Installer,' there you can manage your packages and installations. The version number looks like a softmotion package, try to install it. Or repair your whole installation with the CODESYS Installer.

Hi. Does anyone know how to fix a problem with losing focus of a variable in FBD editor. Sometimes when trying to edit variable name, array index, etc. in network, editor randomly exits "text edit mode" and variable is replaced by text you were typing.
