The network works effectively with a handful of nodes (or even just one) in use, but comes into its own
when used in large and perhaps complex scenarios as it conveys vast amounts of data to the
Entranet
rapidly, reliably and efficiently. This makes it ideal for comprehensive monitoring of plant, equipment,
machinery and systems (PEMS).
The
Entranet
acts as an Ethernet device, providing web access to
GATEWAY
, the integrated
device/data management hub. All devices on the network can be configured here as well as the onward
data connections to other systems and platforms via protocols such as BACnet and oBIX. Data can also
be downloaded directly or viewed right there on a dashboard.
The
Entranet
may be also be accessed locally via the serial port connection to enable constant, high
resolution reading of data from all inputs.
2.4 – Monitoring Capabilities
•
Digital Status and Logger
–
Two (optional) digital inputs provide utility and/or maintenance
data. Each can be configured to count pulses, regularly sample the status, or log the exact time of
each change of status.
•
Serial Connection
-
The serial connection enables constant, high resolution reading of data from
all inputs, using an attached computer.
•
Modbus Slaves
-
(optional).
If the device is set up as a Modbus RTU Master and/or a Modbus
TCP/IP Master, data will be received for any coils or registers on Modbus slaves, based on user
configuration.
2.5 – Input Connections
Input wiring must be installed in accordance with national and local regulations/requirements.
All wiring types must be selected appropriately, according to their function and operating
constraints.
The inputs for the
Entranet
require glands or conduit entries in the gland plate at the bottom of the
Entranet
. Care needs to be taken to ensure the IP rating remains intact. Each input can take a wide range
of readily available sensor types. All inputs and outputs are protected against electrostatic discharge
(ESD).
2.5.1 - Connection Details
The connections to the
Entranet
are via cable entry holes in the bottom of the case, where cables pass
through glands and terminate into the spring loaded plug-in terminals mounted on the edge of the printed
circuit board. The case has a detachable plate that is screwed, complete with seal. This plate can be
replaced with a blank or with 4 or 8 holes. The cover over the terminal compartment is screwed complete
with seal.
