1 Device application
The controllers of the EC4-200 series are programmable switching
and control devices. They can be used in domestic applications,
machine building and plant construction. An EC4-200 controller
can be used as a stand-alone PLC or connected to remote input/
output devices via the CANopen interface. This interface also
allows you to communicate with other PLCs (with a CANopen
interface). The controller is programmed with the easy Soft
CoDeSys programming software. This software should be installed
on a standard PC with the Windows NT, 2000 or XP operating
system. Further information on the software is provided in the
manual AWB2700-1437GB.
This software provides you with a simple entry in the IEC
programming languages such as:
• Instruction List (IL)
• Function Block Diagram (FBD)
• Ladder Diagram (LD)
• Structured Text (ST)
• Sequential Function Chart (SFC).
This provides a large number of operators such as:
• Logic operators such as AND, OR, …
• Arithmetic operators such as ADD, MUL, …
• Comparison operators such as <,=, >
You use the programming software to create, test and document
a project. Functions for analog processing, closed-loop control and
function blocks such as timers, counters simplify programming.
