DATAPOINTS
An Excel Web® controller supports up to 600 physical datapoints and an unlimited
number of value datapoints.
A datapoint has different properties according to its type. Properties are displayed
and can be modified via a standard browser on operator interfaces such as laptops,
desktop PCs, or panel PCs. Properties contain information about the given
datapoint. Among many more, this information could be:
•
Present value
•
Transition events
•
Descriptions
•
Input limits values
•
Operating status
•
Elapsed run time
The following sections provide more-detailed information about the different kinds of
datapoints and datapoint properties and explain which properties are assigned to
which datapoints.
In addition, the Excel Web controller has two Integrated I/Os:
Binary Output
•
potential-free relay, SPST (single pole single throw), normally open, 24 Vac +/-
20%, max. 2 A permanent load
•
application-driven
•
1 "active" LED, illuminated when contacts closed
The binary output can be used for connecting an alarm buzzer.
Binary Input
•
potential-free contact, max. 36 Vdc
•
application-driven
•
1 "active" LED, illuminated when contact closed
Physical Datapoints
Physical datapoints are inputs and outputs attached to hardware devices like
sensors and actuators.
The following are examples of physical datapoints:
Analog Inputs NTC, PT 1000, PT 3000, BALCO Sensors (PT 3000/BALCO), standard 0...10 V / 0
(4)...20 mA input, to connect outside air temperature sensors, for example.
Analog Outputs Outputs with a continuous 0...10 V output signal for controlling continuous actuators
Binary Inputs Inputs for processing voltage-free signals (switches, contacts, counters).
Binary Outputs Outputs for driving three-position actuators, for example, a damper motor; two
position devices, for example, a circulation pump; and pulsed outputs
Multi-State Inputs Inputs used for equipment feedback (Automatic, On, Off)
Multi-State Outputs Outputs controlling multi-stage fans (0, 1, 2, 3)
Pulse Converter Digital inputs for processing pulsed signals up to 20 Hz (depending on I/O module
specifications), for example, metered energy consumption.
