p2plant-ioc 1.0.1

Access to process variable of a P2Plant

EPICS softIocPVA for P2Plant devices

Example

Start P2Plant of simulated 8-channel ADC as described in P2Plant.

Run softIocPVA:

python -m p2plant_ioc -l -k

The P2Plant should start streaming data:

ADC:rps=10 reqs:81, trig:69021 client:1, DBG:0
...

Open another terminal to control P2Plant.
Change debugging level of the P2Plant:

python -m p4p.client.cli put p2p:debug=1
# disable debugging:
python -m p4p.client.cli put p2p:debug=0

Change streaming rate of the P2Plant to 1000 Hz (sleep time = 1 ms):

python -m p4p.client.cli put p2p:sleep=1

The P2Plot should indicate the rps (rounds per seconds) change to ~920.
Monitor ADC channel 0:

python -m p4p.client.cli monitor p2p:adc0
p2p:adc0 Sun Mar  9 11:29:44 2025 ntnumericarray([457, 458, 459, ..., 454, 455, 456], dtype=uint16)

Plot ADC0 samples using pvplot:

python -m pvplot V:p2p:adc0
