In order to achieve the best possible communication and a short reaction time to the
expansion modules, it is best to connect them directly via jumper plugs. Here a baud rate of
115200 bit/s is useful. If the devices are installed further away from the EWIO2, a lower baud
rate should be selected. In the pop-up menu the baud rates of 1200, 2400, 4800, 9600,
19200, 38400, 57600 and 115200 bit/s and the parity none with 1 stop bit, none with 2 stop
bits, even and odd parity can be selected. The found expansion modules are set to these
communication parameters after the search.
When the Expert Mode is switched on, see Chapter
"General", the menu window is
expanded.
In the input fields "Repetitions (0...10)" and "Timeout Frame [ms] (0...5000)" you can select
how often a Modbus request should be sent and how long to wait for a response from a
counter.
By activating the action field "Search extension modules" a request is sent with every baud
rate and parity and waited for a response from an extension module.
The search can therefore take up to 60 seconds and cannot be interrupted.
The table shows
the extension modules.
By activating the action field "Save" the settings are set internally.
With each update of the menu window the communication to the modules is checked.
Reachable expansion modules are marked with a green hook, unreachable ones with a red
cross. They can be deleted by clicking the action field with the trashcan symbol.
