6.3.6 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 of the web interface (see 3.1.3 Configuration tab)
can be used to set the limitation:
•
Description mode set to Standard or (if not needed) set to None.
•
Maximum gateway count set to the default value of 20 or 80, or to a lower value.
•
Maximum value count set to the default value of 25 or to a lower value.
•
M-Bus request mode set to Standard (deactivates the request of partly extensive additional
data of the meter).
•
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 pa-
rameters 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.
The meter configuration may also be changed manually by editing the meter configuration file, see
7.4.2
Meter configuration file. 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.
6.4 Meter data transmit error
6.4.1 Meter data not transmitted via Modbus
• Check that the parameters for the Modbus communication (IP and port) are set correctly.
See 3.1.4
Server tab.
• If possible, check the network communication with the remote system using a network analyzer
such as Wireshark
.
Trying to save a meter list that exceeds the internal limit of the webserver leads
to the deletion of the meter list.
