ET 200SP HA for SIMATIC PCS 7, design

Easy handling and high availability

The SIMATIC ET 200SP HA impresses with its particularly simple installation and assembly. The new terminal layout and push-in technology make tool-free wiring possible. Control cabinet configuration is particularly flexible, as the separation of mechanical and electronic components allows the station to be pre-wired without I/O modules. Empty modules can be inserted in the integrated terminal blocks and easily replaced at any time. Station extension during operation offers additional advantages for plant flexibility and availability.

In addition to the option of operating the SIMATIC ET 200SP HA station redundantly over the PROFINET interface, you can also operate the I/O modules redundantly. This option is implemented using a terminal block for integrated I/O redundancy, which is very cost-effective and saves a lot of space. The new design with standardized terminal blocks makes redundant wiring as simple as single operation.

Main components of the SIMATIC ET 200SP HA distributed I/O system

The SIMATIC ET 200SP HA distributed I/O system consists of the following components:

Mounting rail

The mounting rail is required for fitting an ET 200SP HA station in the control cabinet. The IM carrier modules for interface modules, the carrier modules for the I/O modules and the server module are attached to the mounting rail.

IM carrier module for interface modules

Two versions of the IM carrier modules are available:

• IM single carrier module for 1 interface module, for single connection to PROFINET
• IM redundant carrier module for 2 interface modules, for redundant connection to PROFINET

IM 155‑6 PN interface module and BusAdapter

The interface module ensures communication between the ET 200SP HA station and the SIMATIC PCS 7 automation system (controller) over PROFINET. A BusAdapter as a separate component allows a free choice of connection technology:

• BA 2Г—RJ45: 2 electrical connections for bus cable with standard RJ45 connector
• BA 2Г—FC: 2 electrical connections for direct connection of FastConnect bus cable
• BA 2Г—LC: 2 optical ports for fiber-optic cables

Carrier module and terminal blocks for I/O modules

The slots for the I/O modules are created by connecting carrier modules and terminal blocks. The carrier modules provide the electrical and mechanical connections for the individual modules; the terminal blocks contain the process terminals for connecting sensors, actuators and other devices.

Two versions of the carrier modules are available, one with 2 slots and one with 8 slots for I/O modules.

The selection of available terminal blocks determines the following properties:

• Type of load voltage supply
• Formation of potential groups
• Type of required I/O module
• Redundant configuration of I/O modules

I/O modules

Modules with 8 or 16 digital channels (DI, DQ) and with 8 or 16 analog channels (AI, AQ) are available as I/O modules. A relay module (RQ) and a universal analog/digital module (AI-DI/DQ) can also be supplied.

All I/O modules with a signal voltage of up to 24 V DC can also be used redundantly.

Slot covers can be attached if I/O modules are not to be inserted in slots or slots are to be reserved for later expansion. You can insert a label strip for the planned I/O module on the front of the slot cover.

Server module and power bus cover

The server module and power bus cover complete the configuration of the ET 200SP HA station. The power bus cover protects the power bus contacts.
