SCADA 3000 User’s Manual
C Variable
The SCADA 3000 allows up to 1024 floating point variables to be defined in the C program.
The Group specifies which of the 1024 variables is referenced. The Element field is not used
and should be set to 0.
Examples: C,0,0 = This UAF references C variable number 0
V,64,0 = This UAF references C variable number 64
Alarms
The SCADA 3000 has 64 programmable Alarms. The Alarm UAF will return a number from
0-3 that will identify if an alarm exists or not and also if the alarm is a High-level or Low-
level alarm (High-level and Low-level refer to analog signals that moved above or below the
programmed alarm limits). The Group specifies which of the 64 Alarms is referenced. The
Element field is not used and should be set to 0. The table below shows the value that will be
returned for each alarm condition:
Value
Description
0 No Alarm
1 General Alarm (digital or closure)
2 Low-level Alarm
3 High-level Alarm
Examples: A,0,0 = This UAF references the alarm status for Alarm 0
A,19,0 = This UAF references the alarm status for Alarm 19
Diagnostics
The SCADA 3000 Main Unit and expansion modules maintain a set of data for diagnostic
evaluation. The Group number refers to the module address of the hardware in question. A
Group number of 0 identifies the Main Unit and Group numbers 1–15 correspond to module
addresses 1–15. The Element specifies each individual diagnostic parameter. The Element
parameters are different for the Main Unit and the modules. Listed below are the Element
numbers and descriptions for the Main Unit.
