The STEP 7 program for reading the date and time of day and for saving in DB20 beginning
with data byte 100 may appear as follows programmed in STL:
L"ObjectDB27".RecTimeStamp_1
TDB 20.DBD 100
L"ObjectDB27".RecTimeStamp_2
TDB 20.DBD 104
Notes on explanation of the parameters
The detailed descriptions of the blocks in most of the following contain an "Explanation of the
parameters"
section. The following information is available there for each parameter:
Name: Name of the parameter
Declaration: SIMATIC parameter type INPUT, OUTPUT or IN_OUT
Data type: SIMATIC data type
The data types used:
BOOL, BYTE, WORD, DWORD, INT, DINT, ANY, COUNTER and
BLOCK_DB
Default (only applicable for FB parameters)
Default value for the parameter. This value is valid when the parameter is
not specified when the FB is called.
Explanation: Detailed description of the parameter and specification of the allowable
value range.
Note
The data point typicals are described in detail in the following pages. Data point typicals that
are identical except for the number of data points to be processed are included in a single
description.
If there is a difference in the function or in the parameters, the block for which the described
function or parameter is valid is shown in square brackets, for example, [Cnt01D_S].

Before coming to the others, the next section describes commonly recurring parameters
used by several of the data point typicals.
