3.5.3 Activating/deactivating the HTTP server
To protect the Inline Controller against unauthorized access, it may be necessary to
deactivate the HTTP server. The CPU_Set_Value_Request service with Var ID 0173
hex
is
used for this. This service activates or deactivates the HTTP server for the runtime of the
firmware. The set HTTP server state is stored retentively and mapped to the
ETH_SRV_HTTP_ACTIVE system variables. This setting is restored the next time the Inline
Controller is rebooted.
Value range for the CPU_Set_Value_Request service:
Var ID 0173

Value 0000
