To use the transfer output, set the “transfer output type” parameterto any setting other than OFF.(When the “transfer output type” parameter is set to any setting other thanOFF, the “transfer output upper limit” and “transfer output lower limit”parameters will be enabled.)Transfer Output TypeTransfer output typeOFF (See note 1.)SymboloffSet pointspSet point during SP ramp sp-mNoteSetting range--SP lower limit to SP upper limitSP lower limit to SP upper limitPVpvSensor setting range lower limit to Sensorsetting range upper limit orScaling lower limit to Scaling upper limitMV monitor (heating)mv−5.0 to 105.0 (heating/cooling control: 0.0 to105.0) (See note 2.)MV monitor (cooling)c-mv0.0 to 105.0 (See note 2.)(1) The default is OFF.
If the transfer type is set to OFF, the item assigned inthe “control output 1 assignment” parameter will be output on control output 1.(2) The difference between the transfer output value and the linear currentoutput value is illustrated in the following figure.If the linear output is used as the transfer output when the linear currentoutput type is set to 4 to 20 mA, 4.0 mA will be output for 0% and 20.0 mAwill be output for 100%.When a linear output is used for the control output, 3.7 mA is output for0% and 20.3 mA is output for 100% when the control output for heatingis selected to ensure that the control object is controlled at 0% and 100%.101Section 4-14Using the Transfer OutputOutput current (mA)20.320Transfer output valueControl output43.70MV (%)100(The above graph is for when the linear current output type is set to 4 to 20 mA.)Transfer Scaling• Reverse scaling is possible by setting the “transfer output lower limit”parameter larger than the “transfer output upper limit” parameter.
If the“transfer output lower limit” and “transfer output upper limit” parametersare set to the same value when 4 to 20 mA is set, the transfer output willbe output continuously at 0% (4 mA).• If the SP, SP during SP ramp, or PV is selected, the “transfer output lowerlimit” and “transfer output upper limit” parameters will be forcibly initializedto the respective upper and lower setting limits for changes in the upperand lower limits of the SP limiter and the temperature unit.If the MV for heating or MV for cooling is selected, the “transfer outputlower limit” and “transfer output upper limit” parameters will be initializedto 100.0 and 0.0, respectively, when a switch is made between standardcontrol and heating/cooling control using the “standard or heating/cooling”parameter.• The output current when the linear current type is set to 4 to 20 mA, thetransfer output upper limit is set to 90.0, and the transfer output lower limitis set to 10.0 is shown in the following graph.• For scaling from 0.0% to 100.0%, the output for −5.0 to 0.0 will be thesame value as for 0.0%, and the output for 100.0 to 105.0 will be thesame value as for 100.0%Output current (mA)204MV (%)010Transfer outputlower limit90100Transfer outputupper limit(The above graph is for when the linear current output type is set to 4 to 20 mA.)102Section 4-14Using the Transfer OutputOperating ProcedureThe following procedure sets the transfer output for an SP range of −50 to200.Operation LevelC25PV/SP100Initial Setting Levelin-tInput type1.

The “programpattern” parameter can be used to select moving to STOP mode or continuing operation in RUN mode after the program ends.Parameters Related to the Simple Program FunctionParameter nameProgram patternSymbolptrnSet (monitor) valuesOFF, STOP, CONT---Display levelInitial setting levelProgram startSoak timeprstsoakRSET, STRT1 to 9999--min or hOperation levelAdjustment levelSoak time unitt-um (minutes)/h (hours)---Advanced function setting levelWait bandwt-bOFF or 0.1 to 999.9 (See note 2.)Adjustment levelSoak time remainmonitorsktr0 to 9999°C or °F (See notes 1and 2.)min or hNoteUnitOperation level(1) Set for Controllers with Thermocouple/Resistance Thermometer Multi-inputs.

(The program start must be assigned to anevent input. See note.)• Starting with an Operation Command using communications. (When theprogram start is not assigned to an event input.)NoteWhen an event input is used to start and reset the simple program, writing isperformed to EEPROM. Be sure to consider the write life (1 million writes) ofthe EEPROM in the system design.
When the program start is assigned to anevent input, the “program start” parameter will function as a monitor display,and the RSET/STRT displays can be used to check when the event input hasstarted or reset the simple program. When this is done, the “program start”parameter functions as a monitor display only and cannot be changed usingkey operations. If the “program pattern” parameter is set to OFF, the eventinput assignment setting will be initialized to “none.”Soak Time and Wait BandWait bandSet pointWait bandPVRSET → STRT(1)(2) (3)(4)(5)Set pointSet pointSoak timeremainThe wait band is the fixed band within which the process value is stable inrespect to the set point. The soak time is measured within the wait band.
Thetimer that measures the soak time operates only when the process value iswithin the wait band around the set point (i.e., SP ± wait band). In the followingdiagram, the timer will be stopped between the start and (1), (2) and (3), and(4) and (5) and will measure the time only between (1) and (2), (3) and (4),and (5) and the end.Note106If the wait band is set to OFF, the wait band will be treated as infinity and thetimer will measure time continuously after changing from RSET to STRT.Section 4-15Using the Simple Program Function4-15-2 Operation at the Program EndDisplay at the Program EndWhen the program ends, the process value will be displayed on the No.
