Appendix C3: Functional extension - Setpoint programme

The standard functions of the 362MC software can be extendet by additional software in the form of the

Setpoint programme, which is to be installed at the factory. Necessary hardware extensions, such as ex-

tensions to memory areas, etc., are carried out at the same time.

The functional extension Setpoint programme which is described here enables the setpoint control of

ramps, whereby the setpoints, gradients and hold times are stored step by step in the setpoint pro-

grammes and can be recalled as a time-controlled automatic programme.

5 programmes containing 20 individual steps each are available for this purpose.

Selection

The special Setpoint programme function is selected in controllers which are equipped with the

functional extension by assigning a setpoint programme “SpPrgNo” (1 to 5) to the “SpTyp” parameters

in the extended Setpoint menu. This assignment is possible for both the 1

controller (1SpTypA) and the

controller (2SpTypA) of the 362MC. If a changeover input for changeover to the 2

setpoint has been

assigned to one or both controllers, setpoint programmes can be assigned to the 2

setpoints (1SpTypB,

2SpTypB), too. See also Parametrisation and Display.

If setpoint type 1SpTypA=StpPrg1 is set for the 1

controller, for example, the entire sequence of

setpoint programme 1 will be started and the various time setpoints resulting from the programme will be

controlled by the 1

controller.

Programme structure

The basic structure of a setpoint programme is illustrated below by reference to an example. In this

example, a temperature is to be transformed via the setpoint programme into a fixed value for control.

The scaling for the controller has been set at Scale-0=0 and Scale-F=200 for PT100 input and the

dimension has been defined as Dim=°C. See also explanatory note on

Scaling (5.6.2)

The following setpoint programme has been stored:

If the setpoint programme is now started, the process concerned will be continued smoothly from the last

setpoint, in the example at approx. 50°C, and the 1

step will be executed. In the example, the setpoint

is increased to 60°C in 10s. In the following 2

step, the setpoint is increased to 80°C in 45s, i.e. at a

gradient of 0.44°C/s. In the 3

step a hold time of 180s has been defined for the attained level of 80°C.

In the 4

step the setpoint is then increased from 80°C to 95°C in 60s, i.e. at a gradient of 0.25°C/s. As

no value has been programmed in the 5

step, the value of 95°C will be retained as a fixed value.
