For 3.14 the limit is 60 characters not including a terminating null byte.
For 3.13 the limit is 28 characters not including a terminating null byte.

There may be some CA applications that do not accept the longer names but all the major tools should be OK. I believe that SNS has many PV names with more than 28 characters and would have complained if they found problems.

Hello All,

What is the character limit on the length of PV names in EPICS? I have seen things referring to 28 chars, 40 chars and 60 chars. Whilst I have sucessfully made a record with a double alphabet name (i.e. 26x2=52 chars) I am wary that other programs (such as EDM) may have different limits.

Thanks,
Gavin Smith.
