Applies To:
  • CitectSCADA 5.20

Summary:
The new Dialup I/O Devices feature in v5.20 may cause internal driver error messages to be displayed if the connection between the modems is lost. These errors generally should not be displayed but they are useful for debugging purposes. 

Solution:
The reporting of internal driver errors is now controlled by an INI parameter. By default driver error message dialogs are not displayed. If you would like to see these messages to assist in fault finding then set the parameter to 1. This parameter affects all Citect drivers.

[GENERAL]
ShowDriverError=0

Default Value = 0

Allowable Values

0  = Disable driver error message dialogs

1 = Enable driver error message dialogs
