Hello Yong,

As you mentioned, I had installed EPICS base on my local computer and it occured that "caget" didn't work. That is why I started once again checking the configuration of my university subnet's.

I realised that one of the routing table was messed up. Having fixed this, CS-Studio started working with 10.1.3.192 address.

Thanks for a piece of advice.

Hello Kacper,

 

As long as your local computer (CA Client, CS-Studio) and the IOC (CA Server) are on the same subnet and there is no any firewall between them, everything should just work out of the box.

 

Having said that, let’s try to solve your problem.

1. Which version of CS-Studio are you using? To configure “Channel Access”, the “Address List:” should be the broadcast address (10.1.3.255 for your network?);
2. Can you use “caget” or “cainfo” on your local computer to see those PVs? You need to install EPICS Base on your local computer to have the basic CA tools. If “caget” works, then the problem is related to the CS-Studio configuration.

Subject: CA and CS-studio configuration

 

Hello,

I am using Base EPICS 3.15.5. It is installed on the machine which is accessed by me via SSH (IP 10.1.3.193 port 2222 with login and password). On this machine the IOC is running. Currently, channel access address is set to 10.1.3.192:5064 (EPICS_CA_ADDR_LIST = 10.1.3.192:5064, EPICS_CA_AUTO_ADDR_LIST=NO) and on the machine accessed via SSH I can see values of PVs.

This computer is not fast enough it is almost impossible to run CS-studio on it. That is why I have downloaded CS-studio on my local computer and now I am trying to configure CS-Studio and channel access to be able to get PVs values. Unfortunately the results are rather poor. In CS-Studio I still see that the PVs are "Disconnected". I know that in CS-Studio in tab "Preferences" there is field called "Chanel Access" where I can configure parameters and I've been trying to change them with no success. I know also that from IOC level I can configure channel access server and client addresses but I am not sure how the configuration should look like in this kind of subnets.

Should CA server address should be the same as my machine (10.1.3.193)?

I would be grateful for any tips how I should configure CA and CS-Studio.
