Which Controlled Systems Can The Self-Tuning Function Be Used With; Assigning Parameters For The Self-Tuning Function - Siemens SIMATIC S5 Manual

1.2.4 Which Controlled Systems Can the Self-Tuning Function
be Used With?
The self-tuning function can be used with systems which meet the following conditions:
–
–
To convert to degrees Fahrenheit T [ F] = (T

1.2.5 Assigning Parameters for the Self-Tuning Function

Each of the 13 temperature controllers can be assigned parameters to operate as a standard or
self-tuning temperature controller. This allows mixed controlled systems, some meeting the
required conditions and some not meeting the required conditions, to be operated with one
temperature controller module.
The self-tuning function is specified in messages 0 to 12 in the "self-tuning" byte (byte 22).
The self-tuning function and the end of the self-tuning phase are indicated in a separate bit for
heating and cooling.
If only heating parameters and no cooling parameters have been calculated for a 3-step controller,
this is also indicated and a value for the required temperature jump is calculated and indicated to
the user.
