Hello everyone, I have a question about P4P and its support for Channel Access (CA) with a provider flag.
No. PVXS (and by extension P4P >= 4) are only a PVA client/server.
The pvget command includes an option to select the provider, with 'pva' being the default. Here’s an example: $ caget IOC:IN20:EV01:IOC_CPU_LOAD IOC:IN20:EV01:IOC_CPU_LOAD 9.82578 $ pvget IOC:IN20:EV01:IOC_CPU_LOAD Timeout $ pvget -p ca IOC:IN20:EV01:IOC_CPU_LOAD IOC:IN20:EV01:IOC_CPU_LOAD 10.2621 I want to implement something similar using P4P, but I haven’t been able to find a way to do so. Could someone clarify this for me? Thank you for your help! Best regards, Kuktae
