Re: Reg programming in EPICS environment for master slave control

Dear Mark,

Thanks for your reply.

In actual I have around 100 configuration parameters which I have to pass to my Power supply controller. The pulse length is 1000sec and presently I am not considering the change in parameters during pulse.

The PS controller must respond within 100 ms to the set points sent by the main controller . If the parameters are accepted the status can be ready from PS control and if any parameter is not accepted the status can be error or any other state which can depict the issue.

Please let me know if you need any other information.

Regds,

Himanshu

Can you add some information about the performance requirements?

What is your pulse rate?

What is the frequency at which the main controller needs to pass that information to the power supply controllers?

What is the latency you can tolerate, i.e. how long after the main controller sends the information must be acted upon by the power supply controller?

Mark

Subject: Reg programming in EPICS environment for master slave control

Hi,

I have a requirement where the experimental facility has 2 controllers. The main experimental control and the power supply control.
The experiment has to be carried out in coordination of the 2 controllers. The main controller passes the configuration parameters to the power supply controller , which checks the validity of the parameters for the next pulse and apply them to the power supplies.

I want to implement this system using EPICS platform. Can any one provide me some ideas as to how to initiate such kind of control programming using EPICS.
I have some basic idea since I have interface Siemens plcs with EPICS but have not done the master -slave (2 controller) communication at EPICS level.

Pls suggest how such programs can be completed.

Regards,
Himanshu
