Network communication failure - local station

In this section

This section describes what happens when the network communication fails between a local station and a CU-950 Advanced or CU-960 Advanced control unit during a method run.

If the network communication fails

The table below describes what happens when these conditions are fulfilled:

  • A CU-950/CU-960 Advanced controller (with a memory card) is used

  • Data recovery = ON

  • Method behaviour = CONTINUE

    Note: Data recovery and Method behaviour is described in CU-950/CU-960 settings.

  • The network communication is lost between the local station and the CU-950/CU-960.

Step

Action

1

  • The run continues under the control of CU-950/CU-960 during the communication loss.

  • The run data is saved in the CU-950/CU-960 memory card.

2

When communication is reestablished,

  • UNICORN requests the missing data from the CU-950/CU-960

  • the missing data is uploaded to the local station

  • during the upload the message Uploading is displayed under Instruments in the Run Data pane of the System Control module.

3

The run continues as normal
