Set clock in Step 7

WildChild

I am trying to set the PLC clock. I own INT type parameters (Year,month,day,minutes,seconds,day of the week...). I'm reading the Siemens help butI don't know how to convert these integers in a DATE_AND TIME type to use the SFC 0 SET_CLOCK.

How can i define a DATE_AND_TIME type? Do I need to create a DB to introduce the date and hour parameters?

I'm a sea of doubts...

Instructions for inputting the date and time with SFC0 (SET_CLK)
With SFC0 "SET_CLK" (set system clock) you can set the date and time in a CPU. The CPU clock then runs as of this time and date set. With the statement:

"LAR1 P##Date_Time"

the address of the temporary variable "Date_Time" is loaded into the address register AR1. The data is loaded and transferred from the IN variables of the function (type: byte) via indirect addressing to the separate bytes for year, month, day, hour etc. of the variable "DATE_AND_TIME".
Example:

L #Year
//IN variable, type: Byte
//Input for the variable "year" e.g. "B#16#05" for 2005.

T B[AR1,P#0.0]
//Content of the IN variable "Year" is transferred to Byte 0
//of the variable "DATE_AND_TIME".

In the example described above you see the format of the data type "DATE_AND_TIME". More information on the data type "DATE_AND_TIME" is also available in the Online Help of STEP 7, under:

• Format of data type DATE_AND_TIME

With the subsequent call of SFC0 and parameterization with the temp variable "Date_Time" at the input "PDT" the data is transferred to SFC0.

Sorry hdhosseini, but i'm not familiar to program in AWL. I use to program in KOP.

How can I do "LAR1 P##Date_Time" in KOP language?
