Clock (Fb_Time)Graphical Display:Function Description:The programmable WAGO controllers do not incorporate a hardware real-time clock.The function block FbTime allows the simulation of a clock. There is a timediscrepancy of approx. 10 s per day. It is therefore necessary to synchronize thefunction block with an external real-time clock (we recommend to synchronize once aday). Synchronization is done via the inputs “bIN_YEAR“, “bIN_MONTH“,“bIN_DAY“, “bIN_HOUR“, “bIN_MINUTE“, and “bIN_SECOND“.If there is a value change at the input, “bIN_HOUR“, “bIN_MINUTE“ or“bIN_SECOND“, then the corresponding outputs “bOUT_HOUR“, “bOUT_MINUTE“or “bOUT_SECOND“ will be initialized with the new values. This is also the casewith the outputs “bOUT_YEAR“, “bOUT_MONTH“, and „bOUT_DAY“.If there is no input value change, time keeps running at the output, simulating a realtimeclock. At midnight the output value bOUT_DAY is automatically adjusted to thenext day. Leap years are taken into account.At midnight on the last day of the month the output value bOUT_Month is alsoadjusted to the following month. A turn of the year, too, is processed by the functionblock.In consideration of the output values bOUT_YEAR, bOUT_MONTH, and bOUT_DAYthe weekday (Monday .. Sunday = 1 .. 7) is calculated and output at“bWEEK_DAY“.If the input signal “xACTIVE“ is set to “TRUE”, then the outputs bOUT_HOUR,bOUT_MINUTE, and bOUT_SECOND will be initialized with the appropriate inputvalues. With a “FALSE” signal all outputs have the value zero.Notes: The calculation of the weekday in the simulation mode of the WAGO I/O PRO isincorrect. However, the calculation of the controller (except 750-841) is correct. This function block uses some residual variables having a VAR_RETAINdeclaration.Subject to design changes WAGO Kontakttechnik GmbH & Co.
