Programming the PFC Using WAGO-I/O-PRO CAA
Clock
Click the link "Clock" to go to a Web site where you can specify the settings
for the internal real-time clock.
Here, enter the current time and date and also select standard or daylight sav-
ing time.
Note
The internal clock must be (re)set on initial startup, or after 6 days without
power. The "I/O" LED for the controller will flash with the error code 1/10
RTC-Powerfail if the clock is not set.
Note
Switch-over between standard and daylight saving time via Web-based man-
agement system is required when synchronizing the controllers in your net-
work using a time server. The change-over is resolved via function block
PrgDaylightSaving, which you must integrate into the WAGO-I/O-PRO
CAA using the library DaylightSaving.lib. From that point, change-over will
be performed automatically, allowing all functions to be executed properly
and at the right time.
Note
Call up the Web-based management system and set the actual time under
"Clock" in order to restore proper functioning of the controller in the event of
an RTC-Powerfail. The controller will then be fully operational again.
Note
If you are using the software "WAGO-I/O-Check" after a loss of power has
occurred, error messages may be generated. Should this occur, call up the
Web-based management system and set the actual time under "Clock". Then,
call up the "WAGO-I/O-Check" program again.
Note
You can also use a WAGO-RTC module 750-640 at your node to utilize the
actual time (encoded) in your higher-order control system. An even greater
degree of accuracy is achieved using this "Real-Time Clock" module than
that obtained using the real-time clock in the controller.
