If call to GetPLCstatus can't be executed in PLC, then obtained status is disconnected. Status on "None" is not relevant anymore, and is replaced by Disconnected.
These classes are intended for use server-side.
e.g. in a django view.py :
from pyjs.jsonrpc.django import JSONService, jsonremote
jsonservice = JSONRPCService()
@jsonremote(jsonservice)
def test(request, echo_param):
return "echoing the param back: %s" % echo_param
