Re: EPICS support for the Omega Platinum Series PID Controllers

["Wlodek, Jakub via Tech-talk" <tech-talk at aps.anl.gov>]

Hi Alex, Ibrahim,

Thank you for the suggestion - I had seen the omega i series IOC, and was planning to use that as a base if the need for developing a driver arises. Looking through the i series manual it seems there are some similar commands to those used by the Pt series, but the protocols are not a 1-to-1 match, which likely means at least some development work will be required. Thank you for the links they will both come in helpful.

Best,

Jakub

I am guessing the Omega Pt series communication is different from the Omega I series? Here is an internal link to the protocol file for the Omega I series IOC if you have not already seen it:

This should tell you whether or not they are similar.

Hello Jakob,

 

We use CNI3253-C24-DC for rack temperature control applications. We use simple StreamDevice commands to read temperature and write setpoints based on the following manual: omega_CNi16_communications.pdf (lbl.gov). Let me know if you want further information.

 

Regards,

Ibrahim

Hello all,

 

Before I begin making plans to develop a new driver for this purpose, has anyone developed EPICS support for the Omega Platinum Series of PID controllers?

 

The specific model I am thinking of is the CN8PT-445, however, based on my preliminary research it seems that the communication protocols are shared between the models in the Platinum line:

If anyone has had a chance to work with one of these and develop an EPICS driver for it, please let me know!

 

Thanks,

Jakub
