Building Automation 02.12.2005
At the internal M-bus expansion card, up to 12 counter devices can be connected via
pulse adapters. Up to 40 counter devices can be addressed with an external M-bus
level converter. The following external M-bus level converters are supported at present:
• Siemens WZC-P60 / Relay PW60
(the max. number of counter devices is 40.)
• Relay PW20.
The MeterProxy is based on a Windows CE communications platform that can be
easily integrated into existing computer networks.
The following framework requirements must be fulfilled when the MeterProxy is to be
connected to the Internet via a network:
• Automatic assignment of network addresses (DHCP) is preconfigured as the
standard.
• When automatic assignment is not possible within the network, the network address
and the addresses for the naming resolution (DNS or WINS) as gateways as
required must also be entered.
The network administrator must determine the type of addressing (e.g. IT department at
the customer, system technician SBT).
Answer the following questions:
• Does the network have automated addressing (DHCP)?
• If not, which network address (TCP/IP) is available for the MeterProxy and what are
the associated gateway, subnet and WINS/DNS server addresses?
To book data in EMC, the MeterProxy requires Internet access. This can be set up as
follows, depending on the circumstances:
• Network (TCP/IP) connected to the Internet, e.g. customer's company network.
• Dialup modem* for analog telephone connections.
• ISDN terminal adapter* for digital telephone addresses.
• GSM modem* for cases where phone/network connections are unavailable.
* These devices are not delivered with the MeterProxy.
The MeterProxy is an integration unit based on Microsoft Windows CE.
Communications occur exclusively over the following network ports:
• Port 80 http Regular data transmission to EMC.
• Port 21 ftp Only local, no Internet communication.
• Port 443 https Regular data transmission to EMC.
• Port 445 smb Only local, no Internet communication.
Web services takes care of regular data transmission. This type of communication is
possible for most networks without additional modifications to firewalls, etc.
To support the MeterProxy Small Building, a dial-in function (RAS) is available. This
function can be released or locked via DIL switch.
