HA_CS31_TON - HA Turn-On Delay Timer

Function block HA_CS31_TON

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 standard turn-on delay 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 implements a turn-on delay timer. As soon as the IN parameter becomes TRUE, time counting in ET will start (unit: ms). Counting will proceed until the value in ET is equal to PT value. Then, it will remain constant. Q is TRUE when IN is TRUE and ET is equal to PT. Otherwise it is FALSE. Thus, the Q parameter has a rising edge as soon as time indicated in PT has run out (unit: ms).
