HA_CS31_RAMP_REAL - HA Ramp with Real

Function block HA_CS31_RAMP_REAL

General Information

Available as of PLC runtime system	V1.3 and above
Included in library	HA_CS31_AC500_V13.lib (V1.3) and above
Type	Function Block with historical values.

This function block is a real ramp generator with automatic data synchronization in a High Availability application.

Note

Only internal variables and outputs are synchronized. Input variables and parameters are not synchronized. If needed, use HA_CS31_DATA_SYNC to achieve the same.

This function block serves to limit ascending or descending of a function:

The input consists of three REAL values: IN (function input), and ASCEND and DESCEND, the maximum increase or decrease for a given time interval, which is defined by the TIMEBASE parameter. Setting RESET parameter to TRUE causes the function block to be initialized anew.

The output OUT of the type REAL contains ascends and descends limited function value. When the TIMEBASE parameter is set to t#0s, ASCEND and DESCEND are not related to the time interval, but remain the same.
