Code Sample Descriptions
Simple Output Toggle (Structured Text)
IF Input_Signal THEN
DO_Toggle := NOT DO_Toggle
END_IF
Toggles a digital output whenever an input signal is TRUE.
Motor Start Logic
IF Start_Button AND NOT Stop_Button THEN
Motor_Running := TRUE
ELSE
Motor_Running := FALSE
END_IF
Starts the motor when Start is pressed and Stop is not active.
Analog Scaling Function
Scaled_Value := (AI_Raw - 0) * (100.0 - 0.0) / (27648 - 0)
Scales a raw analog input to engineering units.
Timer Example (TON)
TON_1(IN := Enable_Signal, PT := T#5S)
IF TON_1.Q THEN
Output_Signal := TRUE
END_IF
Runs a TON timer when input is true and sets an output.
Rising Edge Detection
R_TRIG_1(CLK := Input_Flag)
IF R_TRIG_1.Q THEN
Pulse_Output := TRUE
END_IF
Detects rising edges of a boolean input.
Basic PID Control Assignment
PID_1.PV := Tank_Level
PID_1.SP := Level_Setpoint
Controller_Output := PID_1.CV
Assigns process variables into a PID block.
Fault Latching Logic
IF Fault_Signal THEN
Fault_Latched := TRUE
END_IF
IF Reset_Button THEN
Fault_Latched := FALSE
END_IF
Latches a fault until reset is pressed.
Counter Up Logic
CTU_1(CU := Pulse_In, R := Reset_Counter, PV := 100)
Pulse_Count := CTU_1.CV
Counts the number of pulses received.
Mode Selection (Auto/Manual)
IF Mode_Select = 1 THEN
Auto_Mode := TRUE
Manual_Mode := FALSE
ELSE
Auto_Mode := FALSE
Manual_Mode := TRUE
END_IF
Switches control mode based on selector input.
Emergency Stop Logic
IF EStop_Active THEN
All_Outputs := FALSE
END_IF
Turns off all outputs when E-Stop is active.
Frequently Asked Questions about Abb-control-builder
What is Abb-control-builder?
ABB Control Builder is an engineering and programming environment for ABB 800xA and AC800M PLCs, enabling development, configuration, testing, and deployment of industrial control applications using IEC 61131-3 languages within ABB’s integrated automation ecosystem.
What are the primary use cases for Abb-control-builder?
