Integrated Blocks and Their Functions
The parameter blocks listed in Table 9-1 are used for the S5-100U.
Block ID
Start ID
'DB1 ';
S INEC L1 : Parameter block for SINEC L1 configuration /
'SL1:
';
(see chapter 13)
Cl ock- P arameters: Parameter block for integral time clock/
'CLP: ':
clock function not activated (see chapter 12)
'SDP: ';
System- D ependent P arameter: Parameter block for system specifications /
default setting for cycle time monitoring is 500 ms (see section 9.1.8)
'TFB: ';
T imer F unction B locks: Parameter block for time-controlled program
processing: OB13 is called up every 100 ms. (see chapter 7)
E rror R e T urn: Address for parameter error code / no default setting (see
'ERT: ';
section 9.1.2)
END block ID for DB1
'END ';
The sequence of the parameters in DB1 is not fixed. A semicolon must be at the end of each
parameter block with at least one filler between the semicolon and the next block ID.
The structure of the following parameter blocks is described here in detail.
•
ERT:
(Error code position)
•
SDP:
(System specifications)
The parameter blocks that are not discussed here are explained in the chapters that describe their
functions.
9.1.2
Setting the Address for the Parameter Error Code in DB1
For the following reasons, we recommend that you use this example when you start setting your
parameters:
•
Parameter block "ERT:" is the only block with no default parameters in DB1. You must there-
fore enter all the parameters. We will explain the rules for assigning parameters step by step,
so that you can learn the rules quickly.
•
The correctly input "ERT:" parameter block makes it easy for you to correct parameter setting
errors; therefore, you should complete this block in DB1 before you change or add other
parameters.
The error parameter block is only important during the start-up phase. You should erase it
during "normal" operation because it takes up a lot of memory space.
