Webserver capacity error message
After a scan or a change in the meter list, the gateway (even after a reboot) may show the
following error message in the meter list:
The meter list exceeds the capacity of the internal webserver
This error message is caused by an internal limitation of the webserver. The meter list will be
generated in the gateway and meter data will be logged and sent via already configured
interfaces, but configuration of the meters via the web interface is not possible.
This can be caused by a large number of configured meters and/or very long parameter lists of
single meters. To be able to display the meter list, the number of displayed meters or the
number of values per meter need to be limited.
The following parameters on the Configuration tab can be used to set the limitation:
1.
Description mode
set to
Standard
or (if not needed) set to
None
.
2.
Maximum device count
set to the default value of 20 or 80, or to a lower value.
3.
Maximum value count
set to the default value of 25 or to a lower value.
4.
Bus request mode
set to
Standard
(deactivates the request of partly extensive additional
data of the meter).
5.
M-Bus max. multipage
set to the default value of 3 or lower.
Any change of the parameter
Description Mode
will be valid directly after clicking
Save
. All
other parameters need a regeneration of the meter list. This is accomplished by deleting all
meters and saving the now empty meter list, then performing a new scan.
Trying to save a meter list that exceeds the internal limit of the webserver leads to
the deletion of the meter list.
The meter configuration may also be changed manually by editing the meter configuration file,
see
Configuration Files, p. 39
. The gateway needs to be restarted for the changes to take effect.
It is not possible to display the meter list in the web interface when manual editing is used.

Meter Data Transmit Error
Meter data is not transmitted via Modbus
1.
Check that the parameters for Modbus communication (IP address and port) are set
correctly in the Server tab.
2.
If possible, check the network communication with the remote system using a network
analyzer such as
Wireshark
.
