Summary:

This article describes how to modify a threshold value of a register, using SCADA BASIC.
Details:

When a threshold value of a register variable is modified by a SCADA BASIC instruction, the value of the threshold variable is not re-calculated with the new threshold value. For instance:

VARIABLE (“THRESHOLD_SETVALUE”,”variable_name”,rank, value),

To cause re-calculation, the value of the variable must change.

The following instructions will refresh the register variable and update the thresholds.

VARIABLE(“DISABLE”,”variable_name”)
VARIABLE(“ENABLE”,”variable_name”)
