1 Preface on Test Program
The chosen example shows how parameters could be assigned to a module.
The example with indirect parameter assignment covers all possible modes, i.e. the complete
range of commands, whereas the example for direct parameter assignment is limited to the
following operating modes:
Command Message number
PA – assign parameters –
IW – read actual value 17
LE – read the controller parameters 0
AE – change the controller parameters 0
AS – change setpoints 0
AB/HB – switch over to automatic/manual operation 0
S1/S2 – switch over setpoints 0
All the required blocks for receiving data are present and installed.
The example uses data blocks with the following designations:
DB-A : DB 162
DB-B : DB 163
DB-C : DB 164
DB-A’ : DB 172
DB-C’ : DB 173
The function block FB 62 in the test program operates with direct parameter assignment, FB 63
with indirect parameter assignment. During indirect parameter assignment the parameters are
read from the data block DB 162.
In a cold restart the IP 244 is assigned new parameters using the command KS (cold restart).
In both ”automatic warm restart” and ”manual warm restart”, the command PA (assign
parameters) is executed.
