Without sensors most electronic applications would not exist-sensors perform a vital function, namely providing an interface to the real world. Hall effect sensors, based on a magnetic phenomena, are one of the most commonly used sensing technologies today. In the 1970s it became possible to build Hall effect sensors on integrated circuits with onboard signal processing circuitry, vastly reducing the cost and enabling widespread practical use. One of the first major applications was in computer keyboards, replacing mechanical contacts. Hundreds of millions of these devices are now manufactured each year for use in a great variety of applications, including automobiles, computers, industrial control systems, cell phones, and many others.

Soft-CoDeSys – programming to international standards

The easySoft-CoDeSys programming software is a continuation of XSOFT-PROFESSIONAL.

easySoft-Codesys programming system easySoft-CoDeSys is a programming system, based on CoDeSys 3S for industrial plc compliant with the international Standard IEC 61131-3.

Fully developed technical features, easy handling and the widespread use of this software in the automation components of different manufacturers guarantee successful programming with this software.
Programming languages

* Instruction list (IL) and structured text (ST)
* Function block diagram (FBD)
* Freely definable graphical function block chart/continuous function chart (CFC)
* Ladder diagram (LD)
* Sequential function chart (SFC).

Testing and commissioning

easySoft-CoDeSys offers you a number of important functions for debugging your PLC application quickly and efficiently, for testing and commissioning. All these features are available, as soon as you have logged onto the PLC (online mode).
Simulation

easySoft-Codesys: Simulation You can test your application program even without the controller being connected. For this purpose, easySoft-CoDeSys provides integrated online simulation. You use this on the same operating surface and with the same handling procedure as though you were online with the controller connected.

Multitasking

easySoft-CoDeSys: multitasking The fact that the application is structured in several separate run-time programs (multitasking) optimises the resources of your control system and facilitates the implementation of time-critical tasks.
You can give priority to high-speed processes, and to slower processes aalocate only as much computer time as is necessary.

Fieldbus configurator included

The easySoft-CoDeSys hardware configurator shows all the local I/O and the distributed peripherals (PROFIBUS or CANopen) on a single level. This allows you to configure inputs and outputs directly, allocating their parameters and their symbolic names. This prevents assignment errors between peripherals and the IEC based program. In addition, you can also test the variables in online operation.
Modular PLC – tailored to the application

The modular PLCs are characterised by having a wide spectrum of applications with freely scalable structure to suit. The user thus has the flexibility of designing his automation system precisely to his requirement.

Access via the Ethernet for example, is absolutely essential for many applications, for efficient communication between the PLCs within the system on the one hand, and for data exchange with primary level control systems via communication standards such as OPC on the other.
