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.
