Changed Data Queue The Changed Data Queue is a tool for hosts which need to maintain a mirror image database of the PPC 2000 database Typically these are PC based hosts Most simple operator interfaces such as operator interface terminals constantly query the PPC for only the information that needs to be displayed on the current screen These devices would not read the queue The PPC 2000 can communicate with 1 or 2 host devices with read write capability If 2 hosts are used the changed data queue alerts port 1 host that port 2 host has changed a section s of the database and vice versa Each port has a dedicated queue which must be continuously monitored by the respective host The addresses are the same for both ports but the data in each queue may differ because port 1 queue monitors port 2 activity while port 2 queue monitors port 1 activity The queue consists of a group of read only registers Register 33051 contains the quantity of parameters which have been changed by the other host Registers 33052 N form a first in first out stack of changed parameters consisting of the parameter ID numbers The queue does not report the changed status of specific elements within a parameter but only the parameter ID number that has been changed Therefore if the changed data queue notifies host 1 that host 2 has changed a parameter it is necessary for host 1 to read all elements within a parameter to update host 1 s database Usin

Min Set Point When the primary channel s output is 0 the 13907 secondary channel s set point is 150 F Max Set Point When the primary channel s output is 100 the 10E secondary channel s set point is 190 F Heat Prop Band Heat Integral Heat Derivative The secondary channel s PID parameter values may be determined by autotuning or manual tuning As the temperature in the middle of the tank channel 1 drops the output goes up proportionally and the set point of channel 2 goes up proportionally Thus heat is added to the system at the element even though the temperature near the element may have been at the desired temperature With proportional control when channel 1 is at set point its output is 0 and the set point of channel 2 is equal to the desired temperature 150 F Ifthe temperature of the channel 1 drops below 149 F the deviation results in a proportional output of 10 This results in an increase to the set point for channel 2 equal to 10 of the set point range The set point range is defined by Max Set Point Min Set Point In this case the range is 40 F 190 F 150 F 40 F Ten percent of 40 F is 4 F So when the temperature at channel 2 drops 1 degree channel 2 s set point increases by 4 F to 154 F For every degree channel 1 drops channel 2 s set point increases by 4 F until channel 1 s output is 100 and channel 2 s set point is 190 F At t

Control On Off control is the simplest way to control a process a controller using On Off control turns an output on or off when the process variable reaches limits around the desired setpoint This limit is adjustable Watlow Anafaze controllers use an adjustable spread For example if the set point is 1000 F and the spread is 20 F the heat output switches On when the process variable drops below 980 F and Off when the process rises above 1000 F A process using On Off control cycles around the set point Figure 6 1 illustrates this example Heat off Heat off Sanka ee 4 SP 1000 F PV SP Spread 980 F Off Be ea eat 4 ee Figure 6 1 On Off Control 220 Watlow Anafaze Doc 30002 00 Rev 2 3 PPC 2000 User s Guide Chapter 6 Tuning and Control Proportional Control Doc 30002 00 Rev 2 3 Proportional control eliminates cycling by increasing or decreasing the output in proportion to the process variable s deviation from the setpoint The magnitude of proportional response is defined by the Proportional Band PB outside this band the output is either 100 or 0 Within the proportional band the output power is proportional to the PV s difference from the setpoint For example if the setpoint is 1000 F and the PB is 20 F the output is e 0 when the process variable is 1000 F or above e 50 when the process variable is 990 F e 75 when the process variable is 985 F e 100
