Subject: cannot read ioc PVs with caget

Hi all,

 

To start from the beginning. I’m quite new to EPICS, and I’m experimenting with its basics at the moment,

by trying to set up a softIoc from scratch.

I have an EPICS base of R3.14.12.5 already installed and the host OS is a RedHat linux.

 

My project structure is as follows:

 

myFirstIoc/

──PowerSupplySimu.db

└───st.cmd                          

 

When I do softIoc st.cmd the ioc is being initialized and is running, at least it seems like.

 

In the softioc shell I can list the records found in the PowerSupplySimu.db file.

 

epics> dbl

PowerSupply1:ReadBack

PowerSupply1:OutputValue

But when I open a terminal and trying to get the value of any of these PVs like:

 

caget PowerSupply1:Readback

 

I get the following response:

 

Channel connect timed out: ’PowerSupply1:Readback’ not found.

 

I was looking for resources on the web but managed to find nothing unfortunately.

I guess I’m overlooking something or some setup is missing, or maybe I’m doing it completely wrong.

 

So what else do I need to get Channel Access work for me?

 

Any help would be appreciated!

 

 

Yours truly,
