[Python] Multiple Toplevel windows using "after" for updates

I am developing a Python Tkinter app which can open multiple instances of a toplevel window.

The following extract tests if an instance of the toplevel class is running and if not, runs a new instance. If it does exist, it brings it to the foreground.

if (ConsoleGui.winlog[pcs] is not None):
try:
ConsoleGui.winlog[pcs].lift()
except:
ConsoleGui.winlog[pcs] = ClassEpsL.CreateEspLog(Console, pcs)
else:
ConsoleGui.winlog[pcs] = ClassEpsL.CreateEspLog(Console, pcs)


This works nicley.

My problem is the each instance of the toplevel window, has a function which runs in an "after" loop to update a text widget eg

def CreateEspLog(self, pcs):
espLWin = Toplevel(self)
...
text = Text(espLWin, wrap="none", width=600, height=400)
...
def refreshEspL(self):
print("pcsNode: {}".format(ClassEpsL.pcsNode))
if MQTT.BrokerConnected:
ClassEpsL.espLogUpdate(self)
espLWin.after(200, refreshEspL, self)

espLWin.after(200, refreshEspL, self)
return espLWin


The latest instance of the toplevel window takes over the running of this loop from the older ones which no longer update.

I haven't been able to find a solution to either:

create instances which are somehow uniquely identified for the line:

espLWin.after(200, refreshEspL, self)


Or can I somehow call my toplevel window function refreshEspL from my root window eg

ConsoleGui.winlog[pcs].refreshEspL(self)
