Webpage
In addition to providing an interface to read and write the TCP/IP configuration values, the webpage
also provides the user with a view of the current status of the MB40
Figure 1: MB40 Webpage
The webpage gives an indication of the current communication status between the gateway and
weather station, either “GOOD” or “BAD” for each data packet.
Directly above the horizontal line reads the MAC address for the MB40. This identifier is globally
unique.
Directly below the horizontal line are the configuration fields for the gateway, and a line of text
reading: “After power cycle, the TCP/IP settings will load from: <dynamic value>”. This text will read
either “switches” or “memory” based on the status of TCP switch 1. It is important to realise that the
TCP/IP settings may still be read from the switches on power up, despite changing them using
Modbus or the webpage.
