Honeywell timer instruction like TON_UINT, TOFF_UINT, TMR_UINT, TP_UINT, TRTG_UINT used for setting a timer preset value as integer. in this article we discuss how to use these instruction for setting a preset value as integer. working of timer same as describe in part 1 link for part 1 of Honeywell PLC Timer Instruction given below on the article.

how to define timer preset value

Honeywell have special timer instruction to define timer preset value in the form of numerical value or integer value. these instruction are TON_UINT, TOF_UINT, TMR_UINT, TP_UINT, TRTG_UINT. these all timer known as timer with integer setting.

Honeywell PLC On-Delay Timer with integer setting (TON_UINT) Instruction Tutorials

Honeywell PLC On-Delay Timer with integer setting (TON_UINT) Instruction work same same as on delay timer. preset time depend on PT and UNIT input. preset time = PT X UNIT(ms). data type of PT and UNIT is UINT(unsigned integer).

input
• IN : BOOl data type, if it's true than timer operation start.
• PT : PT data type UInt set the base of timer.
• UNIT : UNIT data type UInt integer value of timer.
output
• ET : elapsed time of timer when timer start than elapsed time increment from 0 to preset value.
• Q : output of timer, true when elapsed time is equal to preset value.

above is the example of Honeywell PLC On-Delay Timer with integer setting (TON_UINT) Instruction if the PT = 1 and UNIT = 1000 than timer running period = 1 x 1000(ms)=1sec.

Honeywell PLC Pulse timer with integer setting (TP_UINT) Instruction Tutorials

Honeywell PLC Pulse timer with integer setting (TP_UINT) Instruction work same as pulse timer, below is the simple example of TP_UINT.reset input reset the timer.

Honeywell PLC OFF Delay Timer with integer setting(TOF_UINT) Instruction Tutorials

Honeywell PLC OFF Delay Timer with integer setting(TOF_UINT) Instruction operation is same as off delay timer. time is equal to PT x UNIT.

Honeywell PLC Integration Timer with integer setting(TMR_UINT) Instruction Tutorials

Honeywell PLC Integration Timer with integer setting(TMR_UINT) Instruction work same as Integration Timer(TMR).

Honeywell PLC Retriggerable Timer with integer setting (TRTG_UINT) Instruction Tutorials

Honeywell PLC Retriggerable Timer with integer setting (TRTG_UINT) Instruction work same as Retriggerable Timer with integer setting.
