WATTrouter M - user manual
How to fit and setup the device
Page 24 from 79
a)
Over the existing network architecture, ie Ethernet or WIFI. This is only possible if the device is
connected to an Ethernet network. Therefore, it cannot be used for WATTrouter ECO.
b)
Over the wireless architecture. This is only possible if a SC-Gateway or SC-Router module is inserted in
the device. Therefore, it cannot be used for WATTrouter M and Heating Control.
Attention:
In the case of ad a) communication is provided by UDP and TCP protocols. Regarding the
requirements for the UDP protocol, see chapter Pairing of stations to the access point. Port 50160 is used for
TCP communication. For communication to work, this port must not be blocked on the network. In order for the
communication to work without problems, the local network must not be excessively overloaded with other
communication, eg by downloading large files, videos, etc.
Attention:
Communication in case of ad a) is not secured. It may take place only in the local network or in a
network that is sufficiently secured against unauthorized access!
Attention:
Communication in case of ad b) only transmits information about the status of the outputs, due to
limited data throughput. Therefore, the states of the inputs (binary inputs, temperatures, powers) and the
states of the memory cells are not transmitted!
The term device means hardware device that a controller supports and that holds certain status information, or
measure certain physical quantities.
In the current version, the S-Connect protocol allows you to transfer information from the following devices:
a)
Binary input. Status information 0 (off) or 1 (on).
b)
Temperature. The temperature data is transmitted with a resolution of 0.1 ° C.
c)
Performance. The instantaneous active power data with a resolution of 1W is transmitted. In addition,
some auxiliary data is transmitted, such as the daily and total energy measured by the respective
device.
d)
Output. The output excitation data in the range of 0 to 1000 is transmitted, where 0 means the output
is switched off and 1000 means the output is fully switched on. In addition, some auxiliary data is
transmitted, such as the output hardware type, the assigned output function, or the possible output
restriction.
e)
Memory. The memory cell status is transferred. The memory cell can hold any status information
described in the previous points.
The S-Connect protocol works based on the access point's communication with remote stations, similar to how
computers connect to a WIFI access point. The access point is always 1 device that the user chooses.
The access point controls the communication with remote stations and their pairing. There cannot be 2 access
points in one S-Connect network, but there can be several S-Connect networks, ie several access points, within
a local Ethernet network.
Example 1:
A typical example of an access point is the Wattrouter Mx controller, which provides power
measurement on phases L1 to L3 and also switches the connected appliances (loads) according to the
photovoltaic excess energy. Another Wattrouter Mx controller is then connected to it as a remote station, which
only serves as an output expansion module. The S-Connect protocol is transmitted via the Ethernet network.
Example 2:
Another example of an access point is the Heating Control controller, which controls the building
heating. The Wattrouter Mx controller then connects to it as a remote station and shares information about the
low tariff, temperature data, or excitation of the output needed to optimize the operation of a heat pump
according to the photovoltaics excess energy (heat pump that is connected to Heating Control). The S-Connect
protocol is transmitted via the Ethernet network.
Example 3:
Another example of an access point is again the Wattrouter Mx controller, which provides power
measurement on phases L1-L3 and switches the connected appliances and at the same time it has the SC-
