Basic Function Block Library

Every

drive.web

device has a Basic Function Block Library that includes a useful range of functions that can be instantiated as often as necessary and connected by drag & drop to perform basic control schemes. All function block graphics are dynamic, so all objects such as switches, contacts, indicators and parameters show their real-time state or value.

Basic Arithmetic & Clamps:

Adders, Dividers, Multipliers, Sign Changers, Subtractors, Clamps.

 

Here are examples of some of the Arithmetic function blocks:

 
Adder FB
Multiplier FB
Clamp FB

PI Controller:

The basic PI controller is suitable for most closed loop control applications.

 

This function block includes all of the features you will need for demanding industrial applications, such as:

  • Integral preset
  • Independent upper and lower output clamps
  • Together with monitoring points for all the key variables including error, clamp state, and PI terms

Here is an example of the PI Controller Function Block:
PI Controller FB

Logic & Switch Functions:

AND, NOT, OR, 2-In Switch, 2-Out Switch

 

Easy to use logic functions enable you to build basic interlocks and control schemes. Here are examples of some of the logic function blocks:

 
AND FB
2-IN Switch FB

savvyPanel Functions:

These control the behavior of

savvyPanel

touchscreen devices such as pushbuttons, setters, meters and indicator lamps.

 

The Function Blocks include setpoint/feedback monitors, set/reset latches, monitors, setters, etc.

 

Here is an examples of a savvyPanel function blocks:

 

SP + Monitor FB

Utility Function Blocks:

Utilities enable you to handle different data types, send event driven emails and monitor the operation of your system and network.

  • Parameter blocks for analog, binary, Boolean, enumerations, hexadecimal
  • email notifications
  • Indicators
  • Network statistics
  • Watchdogs

Here are examples of some of the Utility function blocks:

 
E-mail Function Block
Indicator FB
 

Watchdog FB
