The value of the PID feedback can be presented via analog output AO1 or AO2. It is necessary 

to set P0251 (AO1) or P0254 (AO2) to 18 = Function 2 of the Application. The full scale value of 

the variable is 100.0 % and corresponds to 10 V or 20 mA.

The Manual/Auto control is done by a digital input (DI1 to DI8). It is necessary to set one of the 

DI parameters (P0263 to P0270) to 20 = Function 1 of the Application. If more than one digital 

input is set for this function, the logic operation will consider only the command of the high 

priority level digital input, where: DI1>DI2>DI3>DI4>DI5>DI6>DI7> DI8. If any of the digital inputs 

is set, the PID controller will work only in automatic (Auto) mode.

The Manual/Auto input is active when it is in 24 V indicating automatic control and it is inactive 

in 0 V indicating manual operation.

The digital outputs (DO1 to DO5) can be programmed to trigger comparison logics with the 

process variable (PV). In order to do that, it is necessary to set one of the DO’s parameters 

(P0275 to P0279) to 34 = Function 1 of the Application (VP>VPx) or 35 = Function 2 of the 

Application (VP
