Post by sean-barton on Ambiguous namespace in library dependencies ^{CODESYS Forge talk (Post)}
I've created a very basic version of this problem as a project. Please see attached. One of the libraries in conflict is different from that described above, but the problem is the same. My development environment is 32bit v3.5.16.70 using v3.5.11.0 compiler.

Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
Started playing with the idea of ditching windows for linux, one of the obstacles would be Codesys development. Alternatives: - linux with wine? - Run windows/codesys through virtual machine I guess a vm is the way to go? Anyone out there that could share their experience?

Hi, SM3_Math is actually an internal library of SoftMotion. You can use it. The only restriction is that there is no compatibility guarantee - meaning that POUs in the library may change their interface, get moved/renamed/removed... in future versions of SoftMotion.

it should be something like: fbWebClient : WEB_CLIENT.WebClient; You need to use the "Namespace" of the library, not the name of the library itself.

Thank you seoerr for your suggestion. When I implement that line, I get this error: ** [ERROR] 'OSCAT_BASIC.ARRAY_SDV' is of type FUNCTION and cannot be instantiated** Any other thoughts about instantiating these sections of the library which seem to be provided as source only?

Post by alexgooi on Codesys OPC DA server requires more then 2 GB of ram ^{CODESYS Forge talk (Post)}
Dear Forum, We are currently running into a problem that the CODESYS OPC DA server is running out of RAM (larger than 2 GB). We have a setup of 10 Codesys controllers which features around 300.000 discoverable tags per controller. We are only interested in 10 percent of the tags to be communicated to the OPC-server, this is due to the fact the program consists of arrays of objects which on their part implements arrays of objects, simply reducing the number of discoverable tags is not an option The OPC-DA server loads all the discoverable tags, is it possible to: 1 let the OPC-DA server only load the tags that are requested by the SCADA/MES system. 2 let the OPC-DA server claim more memory. 3 run 2 OPC-DA servers in parallel? Thank you in advance

My colleague has found a tool online, Now it is possible to go to 4 GB instead of 2, which is plenty for now: https://www.techpowerup.com/forums/threads/large-address-aware.112556/ Use at own risk

Post by otdeveloper on IEC 61499 ^{CODESYS Forge talk (Post)}
Hello all, I cannot find anything connecting IEC-61499 to CODESYS. Considering the quality of the CODESYS IEC-61131-3 implementation and that IEC-61499 expands on it, literally including as integral part, why is there no mention of CODESYS and IEC-61499 anywhere on the internet?

Post by paro on OPCUA array max length? ^{CODESYS Forge talk (Post)}
I think the amount of data is already relatively high and maybe it has something to do with that? Maybe also the CPU load of your device? an array with string(5000)? and have you tested with how many array elements it still works?

Post by fraccaroli on New Codesys Library Dependencies ^{CODESYS Forge talk (Post)}
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

Turns out Modbus was working despite the pre-compiler errors; I was reading the wrong addresses of the slave device, which was why I was seeing all 0s. Thanks for ignoring me.
