This python package is used as a core engine for any pydevmgr high level package.
The documentation is on its way, but one may be interested to higher level package such as
Python package to by used as substitute of a real device manager running in a ELT-Software environment when the full ELT-Software environment cannot be used.

> pip install pydevmgr_core pydevmgr_core is not indented to be used directly but used by other pydevmgr related package as a core engine.
For usage here is an example using pydevmgr_ua to access an OPC-UA node :
from pydevmgr_ua import UaRpc, UaNode, UaCom
from pydevmgr_core.nodes import InsideInterval
import time
com = UaCom(address="opc.tcp://192.168.1.11:4840", prefix="MAIN")
target = 7.0
move = UaRpc( com=com, suffix="Motor1.RPC_MoveAbs", args_parser=[float, float])
pos = UaNode( com=com, suffix="Motor1.stat.lrPosActual" )
test = InsideInterval( node = pos, min=target-0.1, max=target+0.1 )
try:
com.connect()
move.call( 7.0, 1 )
while not test.get():
time.sleep(0.1)
print( "posisiotn is", pos.get() )
finally:
com.disconnect()Or using the highest level dedicated for ELT devices:
from pydevmgr_elt import Motor, wait
m1 = Motor('motor1', address="opc.tcp://192.168.1.11:4840", prefix="MAIN.Motor1")
try:
m1.connect()
wait(m1.move_abs(7.0,1.0), lag=0.1)
print( "position is", m1.stat.pos_actual.get() )
finally:
m1.disconnect()
