The OT inslruction outputs the operation result 10 a specified coil.Notes:\. The ST and STI instructions start from the bus line. iISome input devices such as emergency stop switch usually have the Form B (normally closed) contact.When an emergency stop switch with the Form B contact is programmed as input to the FP-M/FP1, usethe ST instruction instead of the ST/ instruction. fXO Yt= The OT instruction cannot start directly from the bus line.

Description The TM instruction is a down type preset timer." If there are not enough TM instruction numbers, you can increase the number by changing thesetting of system register 5. Refer to page 4 J8. "5-4. System Registers", for details on how tochange the number of timer instructions.

Timer set t imeThe fonnula of the timer set time is [the time unit] x [set value)Example: TMX5 K30 (0. J s x 30 = 3 s)

Timer operation" When the decimal constant "K" is specified as a se t value:

Procedure:CD When the mode of the programmable controller is set to

RUN. K30 (decimal) is transferred to set value area SV5. When the leading edge of trigger XO is detected (OFFON), set value K30 is transferred from the SV5 to theelapsed value area EV5.

@ The passed time is subtracted from the EV5 every scanwhile trigger XO is in the ON state.

@ When the data in the elapsed value area EV5 becomes 0,timer contact T5 turns ON and then the YO goes ON. When the "SVn" is specified as a set value:

Procedure:CD When the leading edge of trigger XO is detected (OFF

ON). the value in set value area SV5 is transferred to theelapsed value area EV5. The passed time is subtracted from the EV5 every scanwhile trigger XO is in the ON state.

@ When the data in elapsed value area EV5 becomes O. timercontact T5 turns ON and then YO goes ON.

Notes:

If you turn OFF timer operation tr igger XO in the middle of an operation, the operation will be interruptedand the elapsed time will be reset to O." Timer set value area SV is a memory area for the timer's time setting."The t imer contact goes ON when the value in timer elapsed value area EV becomes O. However, thevalue in t imer elapsed value area EVwill also become 0 in a reset condit ion." For each TM instruction, one SV and EV sel and one contact T are supported as follows:

TM99 SV99 EV99 T99" The timer is reset whenever the power is turned OFF, or the mode is changed from RUN to PROG. Setsystem register 6 to retain the run status.Refer to page 418, "5-4. System Registers", for details about system registers." Since:the timing operation is executed during the scan of the timer instruction, program timer instructionsso that the TM instruction is executed once per scan.Be sure that the "rM instruction is executed once per scan when the INT, JP, LOOP instructions andothersJare programmed.

Changing the value in the set Value Area (SV)All FP-Ms and FPI s can change the value in the set value area (SV), even during RUN mode, using the high-levelinstruction FO (MV) or the programming tool (FP Programmer nor NPST-GR).The range of values that can be specified in the set value area (SV) are:

FPI CI4 and CI6 series: SVO to SVI27All FP-Ms and FPI C24, C40. C56. and cn series: SVO to SV143

High-level Instruction FO (MV):Use the high-level instruction FO (MV) as describedon Lhe righL in order to change the timer settingaccording LO the input conditions.Example: Change the setting from 5. seconds to 2

seconds when input XO goes ON.Refer to page 114, uFO (MV) 16-bit data move" fordetails on the high-level instruction FO (MV).

FP Programmer D:Example: Change the value of SVO from K50 to K20.Sleps:

I) Monitor the status of the word daLa.2) Search for SVO.3) Clear the c ~ n t e n l S of SVO.4) Write the new value.

Notes: Even if the SV value is changed, the setting in the program will not be rewritten. The setting from theprogram is sent to the SV and changed only when the mode is changed back to RUN mode, or thenext time the power is turned ON. When the SV value is rewritten, the currently operating timer will continue operating as-is. The EVvalue will not be changed until the next input ON condition. The value in elapsed value area EV can be changed in the same way.

Example:When fine-tuning the timing during trial operation. youcan change the values of the special data registers01'9040 to 0T9043. in the 0 to 255 range, using thepolentiometers on the front of the main unit.

Explanation of exampleCompares decimal constant K100 with the contents of data register DT0 when trigger X0 turns on.

When DT0 > K100, R900A turns on and external output relay Y10 turns on.

When DT0 = K100, R900B turns on and external output relay Y11 turns on.

When DT0 < K100, R900C turns on and external output relay Y12 turns on.

DescriptionCompares the 16-bit data specified by S1 with that specified by S2. The comparison result is output to the

special internal relays R9009, R900A, R900B and R900C.

The following table lists the states of the carry flag (R9009), > flag (R900A), = flag (R900B), and < flag

(R900C), depending on the relative sizes of S1 and S2.

Execution condition (Trigger)In this program example, the comparison will be performed only when X0 turns on.

If ongoing comparison is necessary, relay R9010, which is always on, should be used in the execution

conditions (trigger).

R9010 can be eliminated in this case.

Precautions when using two or more comparison instructionsThe comparison instruction flags R900A to R900C are updated with each execution of the comparison

instruction.

If you use two or more comparison instructions in your program, be sure to use the flags immediately after

each comparison instruction, by employing output relays or internal relays.

Example: Compares DT0 with K100, and DT1 with K200.

Timer operationProcedure:G) When the leading edge of trigger XO is detected

(g) The passed time is subtracted from DT5 every scanwhile trigger XO is in the ON state.

Notes: 18 If you turn OFF trigger XO in the middle of an operation, the operation will be interrupted and the elapsedt ime will be reset to O. Do not overlap the designations for areas that hold settings and areas for elapsed values with othermemory areas for operation of TM/CT instructions and application instructions. The OT instruction can be described continuously even without using R900D. Since the timing operation is executed during the scan of the instruction, program F137 (STMR)instructions so that the F137 (STMR) instruction is executed once per scan.Be sure that the F137 (STMR) instruction is executed once per scan when the INT, JP.

Description The CT instruction is a down type preset counter. If there are not enough CT instruction numbers, you can increase lhe number by changing lheselling of system register 5. Refer to page 418, "5-4. System Registers", for details on how tochange the number of contact numbers.

When programming the CT instruction, be sure to program the count and reset triggers.Count trigger: subtract one count from elapsed value area EV each time its leading edge is

detected.(trigger XO in the example)Reset trigger: reset the counter when this is ON.

Notes: Even if the mode of the programmable control ler is changed from PROG. to RUN, the set value is not setto the elapsed value area.

Changing the value in the Set Value Area (SV)

Notes: Even if the SV value is changed, the setting in the program will not be rewritten. The setting from theprogram is sent to the SV and changed only when the mode is changed back to RUN. or the next time thepower is turned ON. When the SV value is rewritten. the currently operating counter will continue operating as-is. The EVvalue will not be changed until the next time the reset trigger goes from ON to OFF.o If the power is turned OFF, or the mode is switched from RUN to PROG., the counter status will beretained.o The value in the elapsed value area (EV) can be changed in the same way.

Refer to page 429, "5-5. Special Internal Relays", for details about the carry flag.Notes: Specify 01 and 02 as they are in the same type data area and be sure to set the data area addresses sothat 01 02 . If the specified area is set as the hold type, the data in the data area are not reset (become "0") when themode is set to the RUN mode. If you need to reset all the data, turn ON the trigger of the reset triggerusing special internal relay R9013. R9013 turns ON only for one scan duration when the programmablecontroller is set to RUN mode.
