Description
Use the Preset timer -(PT)- and Reset timer -(RT)- coil instructions with either box or coil timers. These
coil instructions can be placed in a mid-line position. The coil output power flow status is always the same
as the coil input status.
• When the -(PT)- coil is activated, the PRESET time element of the specified IEC_Timer DB data is set
to the "PRESET_Tag" time duration.
• When the -(RT)- coil is activated, the ELAPSED time element of the specified IEC_Timer DB data is
reset to 0.
