Pipe Network 2-Axes Template with SFC, ST, FFLD, and FBD

PLC Programs

The 2-axes Pipe Network template has an SFC"Sequential function chart" It can be used to program processes that can be split into steps. The main components of SFC are: - Steps with associated actions - Transitions with associated logic conditions - Directed links between steps and transitions program (called Main) that initializes and starts the motion.

The Pipe Network Template contains an SFC child program called MachineThe complete assembly of all connected parts or devices, of which at least one is movable Logic for running motion.

ST"Structured text" A high-level language that is block structured and syntactically resembles Pascal programs can be found in the P1 and P0 actions for many steps

FFLD programs can be found in the N action for steps 4 and 101

Motion

The template has a motion profile defined with the graphical Pipe Network editor.

The motion profile contains four different pipe blocks:

Call out#

Description

Allows to choose how to run the axes between automatic and manual modes

In manual mode, you can set the speed. You can also set an absolute and relative move. When you click those commands, the two axes move to the specified position and the speed is reset to 0

In automatic mode, you can set the speed

When you click the emergency button, the machine state becomes OFF (see call out ) and the two axes stop running

Based on the template, the project can be run:
