Setting time-related values and actions in the Time service SFB
Apart from date and time, which are independent of the parameterization, you set all other time-
related values and time-controlled actions in the
Time service SFB
of the device parameterization.
The online help provides information on the parameters required for adjustment.
The system time can be compared via the device’s network using
the Network Time Protocol (abbreviation: NTP) to (high) precision time servers.
Activate this parameter and proceed as described in the online help to use this
function.
In the Export values window, the SFB provides time-related events of type
signal in
Basic
system
–
Time service
–
Timer events
. The proChain GC generates these events based on the
system time and the (parameterized) start of the day.
They can be used as input signals for time-controlled actions in other SFBs or AFBs. More
information about the options and settings for time-controlled actions or timer events is provided
in the
online help
.
