Function Block and Structured Text
| If you want to | Use this instruction | 
| Provide alarming for any analog signal. | ALM | 
| Control discrete devices, such as solenoid valves, pumps, and motors, that have only two possible states (e.g., on/off, open/closed, etc.). | D2SD | 
| Control discrete devices, such as high/low/off feeders that have three possible states (e.g., fast/slow/off, forward/stop/reverse, etc.). | D3SD | 
| Perform a delay of a single input. You select the amount of deadtime delay. | DEDT | 
| Convert an input based on a piece-wise linear function. | FGEN | 
| Provide a phase lead-lag compensation for an input signal. | LDLG | 
| Regulate an analog output to maintain a process variable at a certain setpoint, using a PID algorithm. | PIDE | 
| Raise/lower or open/close a device, such as a motor-operated valve, by pulsing open or close contacts. | POSP | 
| Provide for alternating ramp and soak periods to follow a temperature profile. | RMPS | 
| Convert an unscaled input value to a floating point value in engineering units. | SCL | 
| Take the 0-100% output of a PID loop and drive heating and cooling digital output contacts with a periodic pulse. | SRTP | 
| Provide a time-scaled accumulation of an analog input value, such as a volumetric flow. | TOT | 
| Control a single process variable by maintaining a single controller output. | IMC | 
| Control a single process variable by manipulating as many as three different control variables. | CC | 
| Control two process variables to their setpoints using up to three control variables. | MMC |
