Programmer Operation2604 Controller4. Chapter 4 PROGRAMMER OPERATIONThis chapter explains Setpoint Programming and how to Create, Edit and Run programs.Parameters which are associated with setpoint program operation are also listed in tables as ageneral reference.Note: The 2604 controller is an application specific controller and can be configured tothe preferences of a particular process, site or even user. This means that the displaysshown in this and following chapters may not be identical to those shown in yourinstrument. Displays shown in italics are user definable and may, therefore, varybetween instruments.About this ChapterThis chapter describes:◊◊◊◊◊◊The meaning of setpoint programsSetpoint programming terminologyProgrammer typesHow to run, hold or reset a programHow to create or edit a programExamples of how to set up specific features of a program4.1. CUSTOMISABLE PARAMETER NAMESThroughout this chapter parameter names shown in italics are customisable by the userwhen in configuration access level.

2604 Controller Programmer Operation4.2. WHAT IS SETPOINT PROGRAMMING ?In a setpoint programmer you can set up a profile in the controller in which the setpoint variesin a pre-determind way over a period of time. Temperature is a very common applicationwhere it is required to ‘ramp’ the process value from one level to another over a set period oftime.The 2604 controller will program up to three separate profiles. These may be temperature,pressure, light level, humidity, etc., depending on the application, and are referred to asProfiled Setpoints (PSPs).The Program is divided into a flexible number of Segments - each being a single timeduration, - and containing details for each profiled setpoint. The total number of segmentsavailable is 100 per program with a maximum of 500.The 2604 programmer may store up to 20 programs as standard, with up to 50 if purchased,and works on a single timebase for all programs.It is often necessary to switch external devices at particular times during the program. Digital‘event’ outputs can be programmed to operate during those segments.An example containing three profile setpoints and two event outputs is shown below.ProgramPVSegment 1TimeSegment 1TargetSegmentProfileSetpoint1ProfileSetpoint 2ProfileSetpoint 3Start (Run)1h 2h 3h 4h 5h 6h 7h 8h Time1216 X Digital EventsFigure 4-1: A Setpoint ProgramUser Guide.
