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.

Post by rd76065 on Opto 22 Groov PR2 Modbus TCP Master communication ^{CODESYS Forge talk (Post)}
Previously, I have used ModbusEthernet_04 library for Wago for ModbusTCP Master communicational in Codesys V2.3. How to use same communication of similar UDT for Opto22 Groov PR2 PLC in Codesys V3.5 SP20. Can I use OSCAT library - Network -MB_Client or IODrvModbusTCP - ModbusRequest for this requirement? If any other please guide.

Hi, how should that work? You need to download the example project and you need that structure of the project and one of the additional hardware sets https://forge.codesys.com/drv/sm3raspistepper/home/Home/ L298N or A4988, DRV8880. Important to have no GPIO in the project and have this additional tasks.
