ELM System - ELM over Internet Online Demo
We want to provide a way of getting an impression of what the ELM
system does and how administration is done even if the ELM hardware is not
available. Therefore an ELM system application containing a few modules is online for
evaluation purposes. That means, this ELM system is controllable via
internet.
You can try out what ever you
want. For example, you can open handles, watch climatic conditions and
configure alarms.
Your access rights depend on the used login level password (passwords are
given at step 6 below). There are 10 different login levels altogether.
You may use the
SNMP Management Software ELMcontrol
for controlling the sample ELM system over the Internet. You can download
und use ELMcontrol for free.
Steps to make a connection to the internet demo ELM System using ELMcontrol:
| (1) |
Please check that your internet
access does not block SNMP packets and that applications on your
workstation are able to solve DNS names. (If you using a firewall,
check the configured filters.) If you are not sure, don't worry.
Proceed at first with the next step. |
| (2) |
Go online. |
| (3) |
Start ELMcontrol. |
| (4) |
A new entry to the list of ELM
systems must be created:
-
From the main menu, go to the
Options/Configuration window. Within the shown Configuration
window, choose the Network tab.
-
Enter the following name into the Name
field: elm-system.dyndns.org
(Let the IP
address field blank.)
-
Click on the New/Update button. Now
ELMcontrol should inform you by a message box that an IP address was detected
automatically. Click on Ok to quit that message box. If you
get an error message instead, go to step 1.
-
Click on the Ok button to close the
configuration window.
|
| (5) |
Select the ELM system
entry just created and activate the network (within the DATA
CONNECTION area at the left column of the ELMcontrol screen).
A message box should be
shown which informs about your current access permission status. Click
on Ok to quit that message box. If you get a timeout instead (the message "no response from
ELM system …" - right to the EVENT LOG area) then go to
step 1. |
| (6) |
Change your access permission by
clicking the change button within the LOGIN LEVEL area.
The window Login to ELM system is shown. Choose the option
Login with workstation-password and enter a Password. The passwords
for the 10 permission levels are EMKA1, EMKA2,
... EMKA10. |
Note that ELMcontrol may present you a different IP address
automatically once a day. Don't care about that; just login again (repeat
step 6).
As an alternative to ELMcontrol, you may control the ELM system over the
Internet by using of your preferred SNMP manager. You will need the
SNMP Interface specification of the ELM
(ELM-MIB) for configuration of your SNMP manager.
