Return

Lookout remote connection issue
A Lookout control with a Local source and a direct connection does not change if something acts to alter the value or status of the PLC or object it is connected to. Instead, Lookout restores the control value to the PLC or object in the following circumstances: 

  • When the driver object is modified or I/O is reconfigured 
  • When the process is reloaded 
  • When communication is restored after a communications failure 
  • After 100 polls in some cases (this varies from driver to driver and might depend on .ini file settings) 

If you operate a Lookout control with a Remote source connection, and the PLC register it is connected to cannot or does not change when Lookout writes the new value out to the PLC, the control snaps back to display the actual PLC register value or status. Whether or not this issue occurs depends on data transmission time between your Lookout computer and the field hardware. To prevent this issue, Lookout has built-in delays for most driver objects. The following driver objects do not have a built-in delay:

  • AdvantechPCL 
  • DeltaTau 
  • Dynamic 
  • ProfibusDP 
  • ProfibusL2 
  • Reliance 
  • Sixnet 
  • Wizdom 

The following two driver objects do not support remote source connections at all because the underlying protocols do not allow this sort of connection: 

  • Aquatrol 
  • DeviceNet 

Another way to correct snap-back issues caused by slow communication is to adjust the SnapDelay setting that is available with some control objects. For Switch and Pushbutton objects, use the SnapDelay data member; for the Pot object, use the SnapDelay lookout.ini setting.

Workaround: N/A
