Hello, Is there a maximum number of Masters that can connect to a Modbus Slave that is configured in the device tree? Is this limited by the CODESYS IDE, or the manufactures hardware and CPU load? Thank you,

Agree! Me and my customers are buying SL Licences from the store but we don't get proper documentation of the runtime! Only a few hints of the entries in CodesysControl.cfg are spread all over the Internet.

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.

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

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?
