19.1.20 SERVICE_CTRL
The SERVICE_CTRL FB enables or disables connection services, based on the
required service level.
When first called, it runs a process which starts the procedure;
on subsequent calls, it only checks if the process has finished its job.
The FB has the following input parameters:
- SERVICE_ENABLE : TRUE -> enable connection services
FALSE -> disable connection services
- SERVICE_LEVEL : this parameter defines the "Security Level", that is it tells
which connection services shall be enabled/disabled;
possible values are:
0: None
1: VPN Connection
2: VPN Service
3: Internet Connection
4: SMS Service
-1: the value of the "Security Level / Service Disable" configuration parameter
will be used
- TIMEOUT : timeout, in seconds
- @ENABLE : TRUE -> FB is executed
FALSE -> FB is skipped
The FB has the following output parameters:
- RESULT : -2, when called with ENABLE=FALSE
-1, in case of any failure
0, if the process is still running
1, if the process has successfully finished
2, if timeout has expired
- ERROR : this parameter is meaningful only when RESULT=-1; in all other cases,
it is set to 0;
possible values are:
1: the FB has been called with SERVICE_LEVEL=0
2: the procedure to enable/disable the connection services is already running
3: the CPU configuration procedure is running -> FB execution has been aborted
4: connection services are disabled since Remote Connection Disable (RCD)
digital input is HIGH -> FB execution has been aborted
