A function block (FB) is a subroutine that is executed when called from another code
block (OB, FB, or FC). The calling block passes parameters to the FB and also identifies
a specific data block (DB) that stores the data for the specific call or instance of that FB.
Changing the instance DB allows a generic FB to control the operation of a set of
devices. For example, one FB can control several pumps or valves, with different
instance DBs containing the specific operational parameters for each pump or valve.
● A function (FC) is a subroutine that is executed when called from another code block
(OB, FB, or FC). The FC does not have an associated instance DB. The calling block
passes parameters to the FC. The output values from the FC must be written to a
memory address or to a global DB. Based on the requirements of your application, you can choose either a linear structure or a
modular structure for creating your user program:
● A linear program executes all of the instructions for your automation tasks in sequence,
one after the other. Typically, the linear program puts all of the program instructions into
the OB for the cyclic execution of the program (OB 1).
● A modular program calls specific code blocks that perform specific tasks. To create a
modular structure, you divide the complex automation task into smaller subordinate tasks
that correspond to the technological functions of the process. Each code block provides
the program segment for each subordinate task. You structure your program by calling
one of the code blocks from another block. Based on the requirements of your application, you can choose either a linear structure or a

one of the code blocks from another block. By designing FBs and FCs to perform generic tasks, you create modular code blocks. You
then structure your program by having other code blocks call these reusable modules. The
calling block passes device-specific parameters to the called block.
When a code block calls another code block, the CPU executes the program code in the
called block. After execution of the called block is complete, the CPU resumes the execution
of the calling block. Processing continues with execution of the instruction that follows after
the block call.

The program cycle OB contains your main program. You can include more than one program
cycle OB in your user program. During RUN mode, the program cycle OBs execute at the
lowest priority level and can be interrupted by all other types of program processing. The
startup OB does not interrupt the program cycle OB because the CPU executes the startup
OB before going to RUN mode.
After finishing the processing of the program cycle OBs, the CPU immediately executes the
program cycle OBs again. This cyclic processing is the "normal" type of processing used for
programmable logic controllers. For many applications, the entire user program is located in
a single program cycle OB.
You can create other OBs to perform specific functions, such as for handling interrupts and
errors, or for executing specific program code at specific time intervals. These OBs interrupt
the execution of the program cycle OBs.
Use the "Add new block" dialog to create new OBs in your user program.
Interrupt handling is always eventdriven.
When such an event occurs,
the CPU interrupts the execution of
