Post by tyronnosaurus on SysLibMem.lib Where To Download? ^{CODESYS Forge talk (Post)}
It should come by default on a normal install of Codesys 2.3, but it's a bit hidden: Like for any other library, go to Resources > library Manager > Right click on list of libraries > Additional library. On the browser that opens, instead of looking in the default folder, use the dropdown menu at the bottom to change the folder (SysLibMem should be on the 3rd folder).

WAGO will use 0-32767 as the raw units. Note a value of 3 means over/under range. Map that IO however you please, then scale in your program using any of the available libraries or with your own simple y=mx+b scaling formula to get to the engineering units you desire. Inverse for the AO to get back to 0-32767.

Post by trusty-squire on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Just a stab in the dark, but you might want to check the Dynamic Limits (accel, decel, velocity, jerk) in the Codesys SoftMotion device configuration, as well as checking similar limits on your servo drive? Are you seeing any errors, or does the MC_SetPosition FB get marked as complete?

Post by spiritcore on Server not adding PLC ^{CODESYS Forge talk (Post)}
I added new Gateway and I can see it connected. When I scan the server for PLC, it finds the PLC but when I click the Add To Server button, it shows "PLC was added." in the status. But I can't find the PLC in the list. I tried removing the gateway and re-configure everything again but it didn't solve. Any ideas?

Post by helcioburd on How long can a WSTRING be in CodeSys V3? ^{CODESYS Forge talk (Post)}
Thank you, very useful information. I did a library for serial communication and could not understand the reason only 256 chars could be read (after sending more than 256). Following your suggestion, I can now send any number of chars and everything will be received.

Post by chanmina on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
For a long time now, I have used VirtualBox on a Linux Mint host to run the Codesys IDE without any problems. Every day, I put it to good use, and it never fails. Wine is not something to be trifled with. Probably not worth the effort. For Linux PLC developers, Codesys Go might be a game-changer. Very excited to give it a try.

How can I change the default color - blue - for active lanes, contacts and coils? I'd like a lighter color. After having failed in finding a related option in the IDE, I've looked at the "Default.editortheme" file in CODESYS' directory, but couldn't see any related option. Thank you

Post by eschwellinger on TargetVisu option missing in IDE ^{CODESYS Forge talk (Post)}
It is not needed to add Targetvisu connector - for using the TargetVisu for Linux. The reason is - TargetVisu for Linux is basically a remote TargetVisu which could connect to any CODESYS plc not only the loacal one - therefore only a Webvisu connector is needed to have it work. & it seems a bug with this anoying update proposal.

I am struggling with this issue right now (again). I have nested structures with configurable array sizes. In the past I ever used parameter list. Very easy way! As of now I cannot find any solution. Ridiculous that they deprecated it without an alternative solution.

Any reason BIT and BOOL data types are not interchangeable? Trying to make a function which takes a BOOL IN/OUT parameter (Not allowed to use BIT) In the main logic if I make a DINT variable, and want to use each bit on different functions CODESYS will not allow it.

Post by kees-b on PLCnext Phoenix Contact ^{CODESYS Forge talk (Post)}
Hello We started with the new design of Codesys, through a "CODESYS Control Standard S" license. However, after installing the license, connecting, etc. (without any problems), we cannot get the program into the PLC with entries that we have not seen before. Is there anyone who has also experienced this? Better yet, does anyone have the solution?

Hi Martin, I got the messagekey of the "upgrade format warning dialog" with key:"<< No Key>>". (please refer to the attachment) Is that means i can't use system.prompt_answers["<<No Key>>"] = PromptResult.OK; to auto-answer 'OK' in this dialog? Is there any other way to auto-answer this dialog? Thanks!

Post by dhumphries on Using Codesys example problems ^{CODESYS Forge talk (Post)}
You have to install any libraries needed by the sample program. Click the button with ... next to one of the errors (see attached image,) then choose download missing libraries. Codesys should automatically locate and install the missing libraries, it's not flawless though, I've had some issues getting libraries to install. The best advice I can give if it doesn't work is re-install Codesys.

For Raspberry Pi I have made a python script which regularly read a bulk of data over the ic2 from a device. Sometimes I get an Exception an IOError. I assume similar things can happen in CODESYS. So how does CODESYS handle that? Can I get any info about such an event?
