Post by koppit on SysComRead Timeout Parameter ^{CODESYS Forge talk (Post)}
Im using SysCom ver. 3.5.17.0 and seem to have the same issue on a Raspberry Pi. It's not waiting for the requested number of bytes, no matter if "ulTimeout := SYS_INFINITE" or any other value. The only solution I have found is to stall the program to allow the serial port to recieve the data.

Post by vtec35 on search runtime 4.9.0.0 for pi 3 ^{CODESYS Forge talk (Post)}
Hello everyone, following corrupted data on the SD card of our Pi3B+ provided with a machine, we reinstalled a CODESYS image for Raspberry Pi, but we cannot find the 4.9.0.0 runtime that is compatible with the project. Currently, the machine is on 4.1.0.0, and we tried a more recent version 4.13.0.0, but there are error messages. Thanks in advance.

Now that SP21 is out, what's the answer? I want to get a pointer to the TxPDO and RxPDO structs. I can generate a STRUCT declaration from the ESI file with a bit of Python. I just need to get the pointer from the ETC_Slave.

Post by clarenced on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
I am looking for an example of how to run 2 applications on 1 device that would have global variables shared between the two apps. In this case what I am trying to do is to have the main program logic run as one application and then have the visualization run as a second application. I find this https://us.store.codesys.com/media/n98_media_assets/files/000013-F/0/Multiple%20Applications_en.pdf, that talks about exactly what I want to do, but I can't find the download. The main reason I want to do this is for download speed. Right now it takes at least a minute to download our application to the PLC. A simple program downloads to the PLC in a very short time, but add visualization and the download time gets much longer. If I could download the program separately from the visualization I think that a simple program change would take very little time to download. I have tried create a GVL in the POUs view. This partly works in that both applications can see the GVL, but they each create their own instance of it and the variables are not shared between the two apps. There are ideas of using OPCUA but this raises problems with licensing and having to move any variable that needs to be shared into the Symbol Configuration. This adds a lot of management to keep this up to date. Any ideas would be appreciated thanks.
