Thanks Mr. Edwin. It seems the example project direct access to I2C_Master address without using I2C library FB. What if i add I2C_Master and instantiate I2C library FB and use it? (no connection between I2C_Master and I2C device library FB) Nothing happen?
Hi fellow forgers! Currently we are working hard to build a CODESYS compatible Sparkplug Primary Host. A Sparkplug PrimaryHost is the beating heart of the SparkplugB IoT architecture and acts as a central dataconcentrator hub for all Nodes and Devices within the network. Until now, a Primary Host ran exclusively on a PC as a service or executable. Installation of such a machine is not too difficult. However, setup and configuring can be quite a task if you never have used the software before. Our...
@m.prestel I've been playing with the custom user management library provided by 3S (C:\Program Files (x86)\3S CODESYS\CODESYS\Projects\Visu\Dialogs\VisuUserMgmtDialogs.library), however it doesn't seem like this user management system is linked to the stock one in Codesys.

Any ideas why an XY chart would display like the attached screenshot? The curve variable is an ARRAY[1..1440] OF REAL, at the time of the screenshot only a few of the variables had values, between 15.7 and 21.6, and the rest were 0. Autoscale on the y axis is turned on, so I would expect to see the scale between 0 and 21.6. Instead i'm getting these massive numbers on the scale.
it seems to have something to do with the use of reference variables. I have the XY chart in a frame, the interface of which looks like this: VAR_IN_OUT ChartData: ARRAY[1..1440] OF REAL; END_VAR Change it to this, and it works: VAR_INPUT ChartData: ARRAY[1..1440] OF REAL; END_VAR
