In Siemens TIA Portal, an FC is used to define a function which can be executed on command from an organization block, or OB. FC's can be thought of as subroutines which the programmer can call from other blocks in the PLC program.
In this video, we will learn;
1. How to create an FC in the TIA Portal STEP7
environment
2. How to call an FC from an OB
3. How to define the input and output parameters of an
FC.
In a previous video, I showed you how defining a function that can be used over and over is a great way to make a PLC program more efficient and robust.
As a review, in Siemens TIA Portal, an FC is used to define a function which can be executed on command from an organization block, or OB. F...
In the previous video in this 2-part series, I showed you how to use an FC in the TIA Portal STEP7 environment to solve a practical industrial control system problem, in this case, calculation of the level in a cone-bottomed tank.
In the last lesson, I showed you how to use an FC in the TIA Portal STEP7 environment to solve a practical industrial control system problem, in this case, calculation of the level in a cone-bottomed tank.
