Applies To:
  • CitectSCADA 5.xx
Summary:
Take for example, the following project configuration:

Variable Tag:
Name: VAR1 Type: DIGITAL
I/O Device: IODev Address: D1

Alarm Tag: DIG1
Alarm Name: DIG1
Alarm Description: {UserInfo(1)}
Var Tag A: VAR1

With an "ENGINEER" logged in, you trigger VAR1.

The following will appear in the Alarm page:

DIG1 DIG1 EN

You can clearly see that the Alarm Description has been truncated to two characters.
 

Solution:
There is a simple workaround to this problem:

Create a Memory Tag:
Name: CurrentLoginName Data Type: STRING
I/O Device: MEMORY Address: S1

Then create a cicode while loop which is run on startup forever:

WHILE 1 DO
CurrentLoginName=UserInfo(1);
Sleep(1);
END

Then use the String tag in the Alarm Description instead of the cicode function:

Alarm Tag: DIG1
Alarm Name: DIG1
Alarm Description: {CurrentLoginName}

Citect has confirmed this to be a problem in CitectHMI/SCADA versions 5.XX. This problem has been fixed in version 6.00.
