10.3 Adjusting a H/C controller and activating the self-tuning

Adjusting a standard controller (H) as a H/C controller via SDOs, starting the self-tuning and

reading the actual process values (via SDOs) are done as described below.

As only channel 1 is required, the subindex for the channel number must be set to "1".

- Set configuration to offline

→ Index 0x2008 (OPMod=0)

Reference: process data, individual code 31

- Set main controller configuration C100=0x0300 (H/C controller)

→ Index 0x200A

Reference: C100 - controller description

- Set main configuration C200=0x2010 (PT100, unit: C)

→ Index 0x2114

Reference: C200 - controller description

- Set configuration to online

→ Index 0x2008 (OPMod=1)

Reference: process data, individual code 31

- Set set-point Weff

→ Index 0x2313 (Weff=250)

- Start self-tuning

→ Index 0x2206 (OStart=1)

Reference: controller, individual code 34

- Read optimization status

→ Index 0x2250 (State_Tune_1)

Reference: controller, individual code 1

- for( State_Tune_1[ Orun] == 1)

{

- still active, read optimization status

→ Index 0x2250 (State_Tune_1)

Reference: controller, individual code 1

}

- if( State_Tune1[ Oerr == 0])

{

- continue controlling, because optimization successful

- loop for process values:

for(;;)

{

- read effective process value channel 1

→ Index 0x2202

- wait( 1sec)

}
