2. Introduction
The EB3000 is an universal control, display and supervisory device for
EASY
BUS
-sensor modules.
The EB3000 is equipped with 20 internal channels (channel-nr. 1..20), which can be allocated arbitrary to
different
EASY
BUS
-measurement channels and 2 virtual channels (channel-nr. 21 and 22), to download arbi-
trary calculation functions.
Furthermore the EB3000 has 4 switching outputs and an alarm output.
The 22 channels can be allocated arbitrary to the 4 switching outputs to realise different type of control (2-
point-, 3-point-controller, stepping switch etc.).
Due to load arbitrary calculation functions it is possible to realise extensive display and control functions (as
averaging, Difference regulation etc. .
The device features 2 displays: a 4-digit 13mm high 7-segment display (main display) to indicate measure-
ment values or error codes and a 2-digit 7mm
high 7-segment display (auxiliary display) for indication of the
free configurable channel description.
Additionally there are 4 LED´s for displaying the unit of the current measurement channel, 4 LED’s for dis-
playing the actual state of the switching outputs and 3 LED’s which illuminates in case of alarm or in case of a
selected min-/max-value.
The device has 2

BUS
-Interfaces:
- EASY

-output:
connection for the
EASY
BUS
-sensor modules
- EASY
BUS
-input:
permits via level converter (e.g. EBW1, EBW64, ...) communication with a superior
computer (master).
The EB3000 cyclically enquires all the allocated measurement channels. The sequence for processing the
channels isn’t firm, because there is a dynamic request fitted to each channels slightest updating-rate (time-
out). Measurement channels with fast turn of events are frequently requested as measurement channels with
slow turn of events.
The EB3000 checks the compliance of the required updating-rate. If the enquiry of a measurement channel,
within a specified time-interval, as a result of bus capacity overload (e.g. by frequent and time-consuming
enquiries of the master), is not possible, a ‚timeout‘-errormessage indicates on the display and alarm is acti-
vated. If not required, timeout-control can also be deactivated.
Before the EB3000 can be used, it has to be configured for the customer’s application
(see chapter 5).
