Module state bit of the gateways
The module state bits have the following meaning if not otherwise indicated; normally only the
first byte of the total state is transmitted:
0 = error
1 = no error

le 2. This is byte 11 with the hexadecimal value FB (1111 1011):

NOTICE
• Reserved (for future use) = static 1 (no state change)
• Not used (can be 0 or 1 ), both values occur.
• If there is no module, all values - including the reserved values - are set to logical 1.
