Thanks Brian

Would i use the PLC script or the screen load script I'm assuming the PLC

Gary

You got it!

Thanks Brian

This seems to work look ok to you.. no problems down the road?
its in the PLC script

if (pluginState == 0) and (scr.IsLoaded()) then
PluginReg = 0
ProbeState = 0
local Ereg  = mc.mcRegGetHandle(inst,"ESS/Connected")
local Preg = mc.mcRegGetHandle(inst,"PoKeys_40548/DeviceConnected")
if (mc.mcRegGetValue(Preg) == 1) then
     pluginReg  = mc.mcRegGetHandle(inst,"PoKeys_40548/ProbeStatus")
ProbeState = -4
      elseif (mc.mcRegGetValue(Ereg) == 1) then
       pluginReg  = mc.mcRegGetHandle(inst,"ESS/Probing_State")
   ProbeState = -1
end
pluginState = 1
end
Thanks gary

yup that will be fine
