Description

ET 200S function modules are intelligent modules of the discretely modular ET 200S distributed I/O system. They perform technological counting, measuring and positioning tasks to a largely autonomous degree. Parameters are assigned to the modules with STEP 7.
There is no need for an additional parameterization tool.

The ET 200S function modules can be used both via the S7 master as well as the PROFIBUS DP normmaster.
Thanks to the slim and efficient control and check-back interface,  these modules are ideal for applications with several axes and counting channels.
They come equipped with all the advantages of the ET 200S system.

Design and function

Particullarly easy is the configuration and parameterizing of ET 200S Technology modules when employing the new STEP 7 V11 Engineering Software in the TIA Portal engineering framework.

Engineering of SIMATIC ET 200S technology modules

After the ET 200S station has been selected for the project, it is depicted in the structured project tree - complete with the associated device configuration and online diagnostics. All the technology modules that can be configured and programmed in the TIA Portal are shown in the diagram. The procedureis intuitive:

The modules are arranged in the hardware catalog on the right according to topics, and can be selectedby order number and directly "placed" in the rack shown in photographic quality by means of drag-and-drop.

User-friendly parameter assignment at a glance

By selecting the required operating mode (1), the conditions for selecting the possible parameters and the required address space are defined. The appropriate parameters are displayed (2). Context-sensitive selection lists offer exactly the right choice of settings. As required, cascading tool tips provide detailed information about the respective settings and even a direct link to the comprehensive online help system (3). In the background, the appropriate addresses are automatically assigned correctly and, if required, adapted to the requirements of the system.

 The following modules are available:

Counter modules 1 COUNT 5V/24V

The single-channel counter modules 1 COUNT 5 V/24 V are ideally suited to distributed counting and measuring applications. The modules supply the 24 V to the connected encoders.

Position decoder module 1 SSI

The single-channel 1 SSI signal module enables SSI encoders to be connected to ET 200S and allows simple positioning tasks to be implemented. The actual positioning algorithm is processed in the CPU, e.g. with Easy Motion Control.

Stepper motor module 1 STEP

The single-channel stepper motor module 1 STEP performs positioning tasks in combination with stepper motors. It is suitable, for example, for feed equipment in assemblylines, transfer lines, printing machinery, paper and textile machinery.

Positioning module 1 POS U

The single-channel positioning module 1 POS U is suitable for positioning positioning axes and operating axes - for both linear and rotary axes. It is used, for example, in paperand cardboard processing machines, in the food processing industry and in conveyor systems.

Pulse generator module 2 PULSE

The dual-channel technology module 2 PULSE is used to activate final controlling elements and valves. In combination with the SIMATIC software control packages, e.g. Standard PID Control, it can output pulse-width-modulated manipulated variables and therefore off-load the CPU. It can be used for example for controlling semiconductor contactors or for switching heating elements.
