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.
