Description

DigitalPoint

String. (Optional). The name of the digital block that you want to open. If no block is specified, it opens the digital point associated with the selected object.

bstrEventName

Integer. (Optional). The error mode.
0 (default) – Allows the subroutines to provide the error messages. Errors are displayed in the form of a message box. If no entry is made for the intErrorMode parameter, the default is used.

1 – Allows the user to handle the error messages. Errors in the subroutines are passed back to the calling routine for handling.

2 – Writes errors to all destinations. No error messages display. Instead, the errors are written to all iFIX destinations, including the Alarm History window destinations using SendOperatorMessage.

bSendMsg Boolean. (Optional). If TRUE, the message "value changed byxxx" will be sent to the alarm destinations. If FALSE, the message will be suppressed.

Remarks

If no block is specified and the selected object does not have an associated digital point, an error message will occur informing the user that the write was not successful.
