Which difference beetween this (159€) and this ("is free of charge and delivered along with the CODESYS Development System")?
no difference since 3.5SP12 release OPC DA Server need a license.
Thanks for information, Edwin.
I also will be grateful to get answers for next questions:
Hi. Another question about CODESYS OPC.
I have some devices with runtime 188.8.131.52 and some devices with runtime 184.108.40.206.
So I install IDE 3.5 SP5 Patch5 and 3.5 SP12.
As you said before, since SP12 OPC needs to pay license.
But after installing 3.5 SP12 I can't use OPC with SP5 Patch5. I got next error:
Is this expected behavior?
yes this is expected - yopu need a license either demo for testing purpose or full:
