1.
This is how I have understood how Persistent and Retain variables are handled on a softPLC installation (Control Win / Linux etc.)
If I do a graceful shutdown of my OS then all retains and persistent variables are stored on file?
So If I have a UPS and an Industrial PC with Codesys runtime I really have unlimited Retain and Persistent variables? (limited to ram memory capacity?)
Have I understood this correctly or is Retain and Persistent handled differently in this case?
2.
If I for example buy CODESYS Control for Linux SL is this locked to a specific version of the runtime or can the runtime be upgraded without the need of a new license?
3.
CODESYS Control for Linux SL supports CanOpen but where can I find which hardware I can use for CanOpen?
4.
CODESYS Control Win SL under wich operation systems this can be used the following is written:
Windows 7 / 8 / 10 / Embedded (32 / 64 Bit)
Does this mean I only can run it on a computer with embedded version of Windows or can a regular windows installation be used?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
1) yes unlimited - and high performance on shutdown the retain file will be saved on Startup of the plc - restored
(this is all done by the runtime nothing to do additional)
2) no the license is valid for all versions
3) basically on Linux you need Socket CAN - so if you have a socket CAN Driver in your kernel… this should work,
beside that Always possible it to use the EtherCAT - EL6751 CanGateway from Beckhoff. ( no interface in the IPC is needed for doing this)
4) Control Win run on every Windows Version no matter if embedded or not ( expect Windows Embedded Compact 7 - so These former Windows CE systems)

Just a follow up what about Can on a Windows IPC?
There are some models with built in CAN interface how do I know if that Will work with Codesys is there a list of supported interfaces somewhere?

Hi,

Thanks for good answer..

Hi,
Control WIN
USB Peak Sytems
USB IXXAT
Control RTE
Peak PCI/PCI Express and many more ( no USB possible on RTE)
check the RTE documentation.
EL6751 Beckhoff Ethercat - CAN Gateway is possible with all SL Runtimes ( RTE / Control WIN / Linux SL)
