Flexible Datapoints

Flexible datapoints allow the control of more than one physical output with one datapoint. There are three subordinate types of flexible datapoints:

Pulse 2

Multi-stage

Feedback.

Pulse 2 flexible datapoint A pulse 2 datapoint allows to pulse two digital outputs (e.g. relays). When activated (e.g. set to “on”), Pulse 2 triggers one of the digital outputs, and when deactivated, Pulse 2 triggers the other digital output.

Pulse 2 “on”

Pulse 2 “off”

Multistage flexible datapoint Multistage flexible datapoints allow to switch up to six physical digital outputs via one datapoint. A typical example would be a multi-stage electric heater or a multi- stage fan. A multistage flexible datapoint provides up to six editable stage texts, e.g., stage 1, stage 2, stage 3, etc, to be edited in CARE.

Feedback flexible datapoint Feedback flexible datapoints, also called “DO feedback DI” combine up to three pairs of digital outputs/digital inputs to form up to three-stage switching with feedback. The digital inputs of each pair act as the feedback point. If the digital input does not feedback the actual equipment status within a predefined time “Off Phase”, then the software will switch down this point type until a "non-alarm" state is reached. In extreme cases, the point may be switched to the off position. See also “Off Phase”.

Increased support (V2.04.xx or higher) Excel 500 controllers now support up to 60 flexible datapoints. In case of Feedback flexible points, the maximum number is 128.

Previous firmware versions supported only up to 20 flexible datapoints.

Pseudo Datapoints

Excel 50/100/500/600 support 256 pseudo datapoints, while Excel 800 supports 381 datapoints (consisting of a random mix of physical and pseudo datapoints) Pseudo datapoints are values (intermediate results and parameters) computed while the application program is running. In contrast to physical datapoints, pseudo datapoints are not directly connected to hardware devices.

Access via the user address During system operation, you may need to access these values. To simplify this process, you can include pseudo datapoints in the datapoint list, where you can access them directly via their user addresses. Like physical datapoints, pseudo datapoints, too, can have different attributes; for example, they can specify a manual value, set minimum and maximum values, or log trends.

The following are types of pseudo datapoints:
