| Subject: | question about process time of streamdevice |
| From: | Silver <[email protected]> |

I want to use aSub
record to implement some logic by modifying the myAsubProcess function
in dbSubExample.c file.
My aSub record
file is like this:
field(OUTA, "PS1:SETI
CPP")
field(NOVA,"1")
field(FTVA,"FLOAT")
in myAsubProcess function, I can assign the value to OUTA field, for example:
*(float*)precord->vala=
value_xxx
OUTA filed will
drive a PV in streamdevice driver which communicate to a power supply through
ethernet.
My question is: if
I want to measure the time from the beginning of aSub record is processed to
the end of the value is set to power supply correctly? (if the value is set
correctly, the power supply will ack)
Thanks a lot for you help.
