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

Example
Module 2 (SP-SDIO) has a short-circuit after high (24 V) at output 3. The following module state is
transmitted to the network (only the first 20 of 60 bytes are shown):
