Year Timer - Siemens Simatic RTU303xC Series Operating Instructions Manual

5.6.8

Year timer

Requirement
Requirement for a precise calculation is the time-of-day synchronization of the RTU.
Function
For the year timer a time per calendar year and/or per month can be specified in the function
parameters during which the output is set to 1.
The turn on and off times are entered in the format "yyyy-mm-dd hh:mm:ss". Dates can be
entered in the range from January 2000 to December 2099.
By selecting the "Yearly" and "Monthly" check boxes, you determine whether the
programmed time entries are evaluated and repeated annually or monthly.
If you select the "Pulse" option, at the turn on time only a single pulse with the length of an
update cycle is set at the output instead of being permanently ON.
