Mounting rail according to EN 60715

The mounting rail is the module support of the ET 200SP. The ET 200SP is mounting on the mounting rail.

CPU

The CPU:

• executes the user program.
• is used as IO Controller, I-Device on PROFINET IO, or as standalone CPU
• connects the ET 200SP with the IO Devices or the IO Controller
• exchanges data with the I/O modules via the backplane bus

Further functions of the CPU:

• Communication via PROFIBUS DP (in combination with the CM DP communication module, the CPU can be used as DP master or slave)
• Integrated Web server
• Integrated technology
• Integrated trace functionality
• Integrated system diagnostics
• Integrated safety

Open controller

As the first controller of this type, the SIMATIC ET 200SP Open Controller combines the functions of a PC-based software controller with visualization, PC applications and central I/Os (inputs/outputs) in a single, compact device.

• All in one
• High system availability
• Compact and modular
• Rugged
• User-friendly design
• Efficient engineering in the TIA Portal

Interface modules for PROFINET IO (IM 155-6PN)

The interface module:

• is used as IO Device on the PROFINET IO
• connects the ET 200SP with the IO Controller
• exchanges data with the I/O modules via the backplane bus

Interface module for PROFIBUS DP (IM 155-6DP)

The interface module:

• is used as DP slave on the PROFIBUS DP
• connects the ET 200SP with the DP master
• exchanges data with the I/O modules via the backplane bus

BusAdapter (BA)

BusAdapters permit the free selection of the connection method and connection technology for head-end stations with PROFINET interface.

Various versions are available for the connection of copper cables or plastic and glass fiber-optic cables. Hybrid copper/fiber-optic versions are also available as integrated media converters.

Cable length between 2 stations:
max. 100 m (Cu), max. 50 m (POF), max 100 m (PCF), max. 3 km (glass FOC).

For expanding the station with the I/O systems ET 200AL via ET-connection, the BusAdapter BA-Send is available.

BaseUnit (BU)

The BaseUnits provide the electrical and mechanical connection for the ET 200SP components.

• Bright BaseUnits permit a new potential group up to max. 10 A
• Dark BaseUnits forward the self-assembling voltage busbars P1, P2 and AUX from the left to the right BaseUnit.
• Suitable BaseUnits with 12 to 28 terminals are available for different connection systems (single or direct multi-conductor connection) and functions.
• The I/O module is plugged onto the desired BaseUnit and determines the potential assignment of the terminals on the BaseUnit.
• For expanding the station with the I/O systems ET 200AL via ET-connection, the BaseUnit BU-Send is available.

I/O modules and fail-safe I/O modules

The I/O module determines the function at the terminals. The controller detects the current process state via the connected sensors and triggers corresponding responses via the connected actuators. Some I/O modules feature extended functions, in part they are also designed as individual operating mode. I/O module are divided into the following module types; the fail-safe versions are identified by a preceding “F-” and a yellow module enclosure.

• DI (digital input)
• DQ (digital output)
• AI (analog input)
• AQ (analog output)
• TM (technology modules)
• CM (communications modules)
• SM (special modules)

Protective cover (BU cover)

The ET 200SP system can be operated with any number of slot gaps (BU slot without I/O module). Applications for this include:

• partial commissioning
• prewired, and currently unequipped options

To protect against damage, such slot gaps must be covered by a BU cover. Within the BU cover, an equipment labeling plate can be kept for the possible later use of an I/O module.

Versions:

• for BaseUnits with a width of 15 mm
• for BaseUnits with a width of 20 mm

Server module

The server module concludes the setup of an ET 200SP station. On the server module there are holders for 3 spare fuses (5 ? 20 mm). The server module is included in the scope of delivery of all head-end stations.

Coding element

When plugging an I/O module onto a BaseUnit for the first time, the coding element moves from the I/O module to the BaseUnit. There it prevents the destruction of the ET 200SP components in the event of a subsequent module replacement with incorrectly selected I/O module.

The coding element is available in two versions:

• Mechanical coding element
• Electronic coding element:
  Additionally features an electronic, re-writable memory for the redundant storage of module-specific configuration data (e.g. F target address for fail-safe modules, parameter data for IO-Link master). Thus these data are automatically backed up during a module replacement.

Shield connection

The shield connection permits the connection of cable shields. Compared to external shield supports, the system offers the following advantages:

• Quick installation without tools by plugging the shield connection element onto the BaseUnit
• Automatic low-impedance connection to the functional ground (mounting rail)
• Optimized EMC-properties by separating the supply voltage lines from the signal lines by means of the shield connection element and short, unshielded cable lengths
• Low space requirements

Labeling strips

Optionally, for system-specific marking the head-end stations and I/O modules can be equipped with labeling strips (13 x 31 mm). The labeling strips can be inscribed mechanically. Labeling strips are available in two versions in the colors light gray and yellow:

• 500 strips on the roll, for printing on thermal-transfer printers.
  Core diameter 40 mm, external diameter 70 mm, width 62 mm.
• 10 DIN A4 sheets with 100 strips each, card 180 g/mm², perforated, for printing with a laser printer direct from TIA Portal or via print templates.

Equipment labeling plate

Optionally, one equipment labeling plate each can be plugged onto head-end stations, BusAdapters, BaseUnits, and I/O modules. Equipment labeling plates are supplied in packs of 10 sheets with 16 labels each. The labels can be printed with thermal-transfer card printers or plotters, or stickers can be attached to them. Advantages compared to labels that are attached directly:

• The inscription on the front is not covered
• Simple label replacement when replacing a module
• No parallax errors when marking the BaseUnits on the mounting plate

The size of the inscribable area of the labels is 14.8 x 10.5 mm (W x H)

Color-coded labels

The I/O modules that are plugged onto the BaseUnits determine the potentials connected at the process terminals. The +/- potentials can optionally be identified using module-specific color-coded labels. The potentials of the AUX and add-on terminals can also be marked using color-coded labels. Advantages of the color-coded labels:

• Quick installation (one label for marking 16 terminals)
• Avoidance of wiring errors
• Simple detection of potentials during servicing
