3. Control Power Method Regulator Control Loop Measured temperature a Heater 7 1 Types of Control Two types of control loop may be configured These are On Off control PID control 7 1 1 On Off Control On Off control is the simplest means of control and simply turns heating power on when the PV is below setpoint and off when it is above setpoint As a consequence On Off control leads to oscillation of the process variable This oscillation can affect the quality of the final product but may be used on non critical processes A degree of hysteresis must be set in On Off control if the operation of the switching device is to be reduced and relay chatter is to be avoided If cooling is used cooling power is turned on when the PV is above setpoint and off when it is below It is suitable for controlling switching devices such as relays contactors triacs or digital logic devices 7 1 2 PID Control PID also referred to as Three Term Control is an algorithm which continuously adjusts the output according to a set of rules to compensate for changes in the process variable It provides more stable control but the parameters need to be set up to match the characteristics of the process under control The three terms are Proportional band Pb Integral time E Derivative time Ed The output from the controller is the sum of the contributions from these three terms The combined output is a function of the magnitu

5. 8 6 DATA ENCODING Note that the Eurotherm Tools OPC server provides a straightforward means of accessing any variable in the controller in the correct data format without the need to consider data representation However if you wish to write your own communications interface software you will need to take the format used by the Piccolo Range comms software into account Modbus data is normally encoded into a 16 bit signed integer representation Integer format data including any value without a decimal point or represented by a textual value for example off or on is sent as a simple integer value For floating point data the value is represented as a scaled integer in which the value is sent as an integer which gives the result of the value multiplied by 10 to the power of the decimal resolution for that value This is easiest to understand by reference to examples It may be necessary for the Modbus master to insert or remove a decimal point when FP Integer using these values Value Representation It is possible to read floating point data in a native 32 bit IEEE format This is described in the Digital Communications Manual Part Number HA026230 which can be FP Integer downloaded from www eurotherm co uk Value Representation For time data for example the length of a dwell the integer representation depends 3 9 on the resolution For hours resolution the value returned is the number of minutes the va

Deadband For temperature control the action is that the heater power decreases as the PV increases For an on off controller output 1 usually heat will be on 100926 when PV is below the setpoint and output 2 usually cool will be on when PV is above the setpoint Hysteresis applies to on off control only It defines the difference in temperature between the output switching off and switching back on again The examples below show the effect in a heat cool controller Deadband can operate on both on off control or PID control where it has the effect of widening the period when no heating or cooling is applied However in PID control its effect is modified by both the integral and derivative terms Deadband might be used in PID control for example where actuators take time to complete their cycle thus ensuring that heating and cooling are not being applied at the same time Deadband is likely to be used therefore in on off control only The second example below adds a deadband of 20 to the above example Deadband OFF HYST C Example Heating and Cooling Type SP 300 C both on off Setpoint 300 C Control Action reverse Heating Hysteresis 8 C Cooling Hysteresis 10 C Deadband OFF OP1 On Heating 100 No OP OP2 On Cooling 100 tf t 4 Heating Coolingon Cooling Heating on off at SP at SP off at SP at SP 300 C ESTE 300 C HYST H 310 C 292 C Deadband ON HYSTL Example D BAND Heating and

64. High and Low Cutback section PO Derivative is generally used to increase the stability ofthe loop however there are situations where derivative may be the cause of instability For example if the PV is noisy then derivative can amplify that noise and cause excessive output changes in these situations it is often better to disable the derivative and re tune the loop If Ed is set to OFF no derivative action will be applied In the Piccolo range of controllers derivative is calculated on change of PV For applications such as furnace temperature control it is common practice to use Derivative on PV to prevent thermal shock caused by a sudden change of output as a result of a change in setpoint 7 1 6 Cooling Algorithm The method of cooling may vary from application to application For example an extruder barrel may be cooled by forced air from a fan or by circulating water or oil around a jacket The cooling effect will be different depending on the method The cooling algorithm may be set to linear where the controller output changes linearly with the PID demand signal or it may be set to water oil or fan where the output changes non linearly against the PID demand The algorithm provides optimum performance for these methods of cooling The type of cooling is set by P code P8 section 5 2 4 7 1 7 Relative Secondary Cool Gain rgb The proportional band parameter Pb adjusts the proportional band for the heating o
