Compact design, flexible connection possibilities and high system availability with redundant PROFINET connections: the SIMATIC ET 200SP HA distributed I/O system is perfectly suited to the requirements of the process industry. The new design allows up to 56 I/O modules per station. An impressively high concentration of up to 32 channels on a module that is only 22.5 mm wide allows for maximum economy in the control cabinet.

Redundant PROFINET connections allow the connection of high-availability controllers via two independent networks, with a choice of copper or fiber-optic cables. The system can be scaled and extended in small steps using a variety of available modules, for example with digital and analog I/Os as well as NAMUR, HART, and other protocols. All 24 V standard signals are connected via an identical terminal block type, which allows a high degree of standardization for the control cabinets.

SIMATIC ET 200SP HA is designed for use in the control cabinet as well as for hazardous areas up to hazardous zone 2. The extended temperature range from -40 to +70 °C and the conformal coating of all components allow direct installation in the field.

Design

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:

DIN rail

The DIN 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 DIN 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 2×RJ45: 2 electrical connections for bus cable with standard RJ45 connector
  • BA 2×FC: 2 electrical connections for direct connection of FastConnect bus cable
  • BA 2×LC: 2 optical ports for fiber-optic cables
  • BA LC/RJ45: 1 optical connection and 1 electrical connection for bus cable with standard RJ45 connector
  • BA LC/FC: 1 optical connection and 1 electrical connection for direct connection of FastConnect bus cable
  • BA 2×RJ45 (VD): 2 electrical connections for using PROFINET via existing PROFIBUS 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.

Three versions of the carrier modules are available, one with 2 slots (with power bus) and one with 8 slots (with and without power bus) 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.

Redundant configurations

SIMATIC ET 200SP HA, basic redundant configurations

The availability of the ET 200SP HA distributed I/O can if necessary be increased with redundant configurations. A number of different configurations are possible (the individual redundant configurations can also be combined):

Media redundancy

ET 200SP HA stations with 1 interface module each are connected to an automation system in a ring topology. At least one device in the ring takes on the role of the redundancy manager; the other devices in the ring are redundancy clients. The automation system is configured as MRP manager.

If the ring topology is interrupted, the ET 200SP HA stations in the system remain available.

One of the following functions is possible during operation:

  • Connecting and removing ET 200SP HA stations
  • Replacing PROFINET cables

System redundancy

ET 200SP HA stations are connected to a redundant automation system. All components used redundantly are in continuous operation. If a redundancy partner fails, the function is maintained by transferring the master role or selecting a different communication path.

The ET 200SP HA stations remain available in the PROFINET IO system if a CPU or a PROFINET cable fails.

One of the following functions is possible during operation:

  • Connecting and removing ET 200SP HA stations
  • Replacing PROFINET cables
  • Replacing a CPU

I/O redundancy

To configure I/O redundancy, 2 I/O modules of the same type are inserted beside each other in a terminal block for redundant configuration (width: 45 mm). This terminal block connects the process signals of the two modules to a common process terminal. The advantages are:

  • There is less wiring work than for connecting separate I/O modules, as interconnection of the process signals is integrated in the system.
  • Redundant signal processing of the sensors and actuators at a module level increases the availability of the system.

The following applies if an I/O module or a channel of one of the two I/O modules fails:

  • Error-free inputs remain available in the system.
  • Error-free outputs continue to be controlled in the system.

One of the following functions is possible for an I/O module in a module pair in error-free operation:

  • Firmware update
  • Replacing a module
