On the web page below we will post short YouTube Tutorials to briefly explain the configuration and functionalities of the MEMo2 web server. The complete manual can be downloaded here: MEMo2 Handleiding v1
You can either go through the tutorials from start to finish or select the desired video. These tutorials are regularly supplemented and updated.
In the quickstart manual you can find the connection diagram and module configuration per module type: Quick start 2-Wire v2.3
The IP-serverscanner.exe is a software tool that helps you to find the IP address of the web servers in your network. You can download this software tool here.
Once installed you will get a shortcut on your desktop. The video below explains how you use this tool.
When a web server is powered up, its 4 LEDs light up immediately, after only 10 seconds only the top LED (power) stays on continuously and the LED under the left button gets a heartbeat rhythm. Only now is the web server working and is it visible to the server scanner.
Every time a web server is switched on, or when a web server reboots after an upgrade, it tries to connect to the internet to, among other things, synchronize its internal clock with an NTP server.
If there is no internet, the time to heartbeat usually lasts 1 to 2 minutes.
The WS.502 can work simultaneously with 4 users + 1 administrator. Every user can choose a login name (max. 16 characters), a password (always 4 digits) and a language version. You can also set a timeout from 1 to 255 hours or with the number 0 = 30 days.
You can only make changes here if you are logged in as an administrator under “admin2-WIRE” and the default password “2015”. You can never change the login name “admin2-WIRE” or “adminIP”, but you can change the password (2015).
Create additional users:
when creating a new user, use the old login: ‘loginold’ with password ‘1234’
when changing an existing user you start from the existing login and password
With the push buttons on the web server you can reset password and IP address or you can clear the web server completely and bring it back to factory settings
Procedure: Press the desired button while turning on the power and continue to press until the LED just above the corresponding button has completely gone out, only then release and wait for the heartbeat.
2.1 Serial numbers
Meters are added to the web server based on a unique serial number.
The serial number always consists of 2 digits, 1 capital letter, and again 5 digits:
The 2 first digits of the serial number determine the number of outputs / inputs:
The letters have the following meaning:
The following 5 digits are unique, and in case of energy meter and calorie meter you choose this yourself but make sure that the serial number remains “unique”, for the other modules the serial number is printed on the module.
With the EMM.120 and EMM.120CT modules all Modbus settings are pre-configured, the Modbus address is printed on the module or can be read in the display. The Modbus parameters set: 9600.8N1 (Baud rate: 9600 baud; 8 bit; Parity: No parity; 1 stop bit) are also pre-configured.
With the EMM.220 and EMM.630 series you can change all Modbus settings manually via the ‘touch-buttons’ at the display, the Modbus address is set to 1 (ID = 001) by default and to communicate with the Memo server you have to the other Modbus values are at 9600.8N1 (default).
Meters are added to the web server based on a serial number. For the energy meters we choose our serial numbers ourselves (see above: serial numbers)
The RF gateway has 4 analog / binary inputs, a serial P1 port connection to the Dutch and Flemish digital meters and possibly 2 extra pulse inputs via the RJ11 plug (option SET P1).
The configuration in the web server is based on the unique serial number printed on the module. When the gateway is via Modbus we enter the address with capital G: example 08G00411, if the gateway is connected via RF we use lowercase g: example 08g00411.
The configuration of a gateway (slave) which is linked via LoRa to the central Memo web server is identical to a gateway linked via Modbus. You must enter the serial number with lowercase g, for example: ’08g00411′ and the RG gateway must still be connected with the central MEM02 web server.
The procedure for joining:
The configuration of an energy meter that is connected wirelessly via a “slave” gateway to a Memo server is almost identical to an energy meter connected via Modbus. The only difference: the name of the module is now the serial number of the “slave” gateway ….
With the “TEST” button you can read the signal strength.
The configuration of a smart plug is done like any RF module: first the serial number (eg 10S00031) and a unique Modbus address are entered, the module is connected. The signal strength can be read with the test button.
The configuration of a wireless energy counter is done like any RF module: first the serial number (eg 08F00011) and a number of unique Modbus addresses are entered, the module is connected. The signal strength can be read with the test button.
In “Channels” we provide the layout for the end user. With the “sort” button we can change the order of the energy channels, with “groups” we create directories …
The 2-wire modules are installed by the electrician in the fuse box and then the server is connected to the local network.
Through the webservers web pages, the names of consumers, consumption units, energy prices, network setting, ... can easily be configured via tablet or PC.
After the configuration every minute all measured data is read and stored in the web server. All consumption values and energy costs are now accessible via Web browser.
For software developers: 2-WIRE development pack
Download data log files or get them sent periodically, visualization and control from your own application,...
The development pack will explain how this can be done easily. The pak may be obtained free of charge by anyone which owns a 2-Wire Web server.
