The SIPLUS extreme variants of the S7-1200 PLC are developed especially for particularly demanding environmental conditions. They are characterized by their special refining and offer significant advantages:

• Protection from medial impact (aggressive chemical, biological and mechanically active gases and salt mist) and condensation

• High reliability across an extended temperature range in the start-up phase as well as during operation

• Saving costs, since no additional heating or cooling is required

• High productivity and investment protection through minimal downtimes and performance losses

• Altitude up to 5000 meter

Besides the characteristics of the Basic Controller with integrated and decentral IO’s, PROFINET interface for programming and HMI connections, the SIPLUS extreme S7-1200 PLC can provide following advantages for different variants:

• Variant 1: conformal coating version for use in corrosive surroundings
• Variant 2: additional enlarged temperature range from -40 °C up to +70°C (in operation)

Signal boards are connected directly to the front of the CPU. They can be used where space is limited or if only a few additional inputs/outputs are required.

• Each S7-1200 CPU can be modularly expanded by a signal board.

• This does not increase the mounting space required for the controller.

• The portfolio includes digital inputs, digital outputs, mixed digital IOs, analog inputs and analog outputs.

Digital expansion modules provide the option for using further digital inputs/outputs in addition to the existing integral digital inputs/outputs.

Signal modules as separate modules can be used with all SIMATIC S7-1200 CPUs except the CPU 1211C

• For flexible adaptation of the controller to the task at hand. This avoids superfluous investment. Modules with 8, 16 and 32 input/output channels are available.

• For subsequent extension of the system with additional input. If the task is extended subsequently, the controller can be upgraded with one of these digital modules. Updating of the user program in TIA Portal is extremely simple.

The portfolio comprises 12 different modules.

Analog expansion modules provide the option for using further analog inputs/outputs in addition to the existing integral analog inputs/outputs.
Signal modules as separate modules can be used with all SIMATIC S7-1200 CPUs except the CPU 1211C

• The SM 1231 analog input signal modules convert analog signals from the process into digital signals for internal processing by the SIMATIC S7-1200
• The SM 1231 RTD modules enable temperatures to be measured with high precision using resistance-based temperature sensors.
• The SM 1231 thermocouple modules enable temperatures to be measured with high precision using established thermocouples
• The SM 1234 Analog hybrid modules offer analog inputs and outputs on the same module with small footprint.
• The SM1238 Energy Meter module records measured electrical values, such as voltages up to 480 V AC, in a 1 or 3-phase network with a direct connection but without a transformer.

The Fail safe signal  modules for digital inputs and outputs (DI and DQ) correspond to the standard modules with respect to their size. Their functional safety is certified according to EN 61508.

They are designed for safety-related use up to SIL 3 according to EN 62061 and PL e accordingto ISO 13849.

Compact and integrated Condition Monitoring

For permanent status monitoring of critical mechanical components. The recorded data is analyzed by the internal software of the CMS1200 and stored on the SM 1281 condition monitoring module. SIPLUS CMS1200 is fully integrated into the automation system via TIA Portal.

The SIM 1274 Simulator Modules provide users the opportunity for testing user programs. Just mount the input simulator on the modular board instead of the digital inputs. So you could manual set input signal. This signal read by the CPU will be processed in the user program.
There are 4 different modules available:

• SIM 1274, 8 channel DC Input switches for CPU 1211C/1212C
• SIM 1274, 14 channel DC Input switches for CPU 1214C/1215C
• SIM 1274,14 Channel (10x 24V DC Input switches,4X 1.5 V Differential Inputs) for CPU 1217C
• SIM 1274 Analog simulator, 2 Potentiometer inputs for all CPUs of S7-1200

Battery board for extending the power reserve for the S7-1200 real-time clock
The battery board accommodates a standard button cell (CR1025) for the power supply, which can easily be replaced. The button cell is not included in the scope of supply and must be purchased separately.

The battery board is plugged like a signal board directly into the holder on the front of each S7-1200 CPU (FW 3.0 or higher). The installation dimensions of the CPU remain unchanged.

The maintenance LED on the board indicates when it is necessary to change the button cell. The battery status can be assessed at any time via the CPU user program

The weighing modules of the SIWAREX-WP2xx series are technology modules of the basic controllers SIMATIC S7-1200 and can be used in many fields of application: Beside that they are seamlessly integrated in TIA Portal.
There are 3 modules available:

• SIWAREX WP231 is the optimum solution wherever load cells are used for measuring tasks.
• SIWAREX WP241 is the optimal solution wherever belt scales are used that demand high accuracy, high user-friendliness, and flexible system integration. 
• SIWAREX WP251 is a flexible weighing module for fast and precise dosing and filling processes.

Serial communication

The RS485 and RS232 communication modules are suitable for serial, character-based point-to-point connections.
The library functions USS Drive Protocol and Modbus RTU Master and Slave Protocol are already included in the SIMATIC STEP 7 basic engineering system.
The CM 1241 communication modules are used for quick, high-performance serial data exchange via point-to-point connection and available for the RS232 or RS422/485 physical transmission properties

The CB 1241 communication board RS 485 can be plugged directly into all SIMATIC S7-1200 CPUs

Integration of identification systems

Using the RF120C communication module all SIMATIC identification systems (RF200/300/600 and optical reader system MV400) can be connected directly to the SIMATIC S7-1200. A reader can be connected to a RF120C via the point-to-point connection. The RF120C also provides a library with application blocks that are very easy to handle. Configuration is carried out via the TIA Portal.

The use of the SIMATIC S7-1200 as a master or slave on the proven PROFIBUS field bus facilitates standardized communication from the field level through to the control level. This meets one of the most important requirements in the performance range of compact automation.
For the connection of the S7-1200 to PROFIBUS there are two communication modules (CMs):

• The DP-Master CM 1243-5 enables as many as 32 field devices to be connected as slaves, e.g. ET 200 distributed I/O modules.
• Together with the CM 1242-5, the S7-1200 functions as a DP-Slave and can thus be connected to any DP-Master.  

AS-i is an open, manufacturer-independent bus system that organizes the transmission of digital and analog process and machine signals into the control system. The AS-i Master communication module, as the "heart" of the AS-i Fieldbus can record sensors in the field or control actuators in the field.

The connection of an AS-i network to the SIMATIC S7-1200 is quite simple:
The AS-i Master CM 1243-2 communication module is simply plugged into the CPU and wired to the field. The AS-i Master CM 1243-2 thus connects the lowest field level, such as IO modules, position switches, signaling columns, load feeders and motor starters with the higher-level SIMATIC S7-1200 control system.
For each master, up to 62 AS-Interface slaves can be connected.
All the advantages of the TIA Portal apply, such as the fully graphical parameter assignment and diagnostics of all AS-i stations without additional software.

Module for connecting up to 4 IO-Link devices according to IO Link Specification V1.1. The IO-Link parameters are configured using the Port Configuration Tool (PCT), version V3.2 and higher.

The SM 1278 module enables data exchange with up to 4 external IO-Link devices via one 3-wire cable each or four standard actuators/standard sensors. Comprehensive parameterization options make it possible to adapt the controller flexibly to the communication partner. Thanks to the compatibility of IO-Link with standard sensors, commercially available sensors in accordance with IEC 61131 Type 1 can also be operated on the IO-Link master.

The telecontrol communication processors offer a range of different possibilities for the implementation of extremely versatile and cost-efficient Telecontrol remote stations (RTUs) based on SIMATIC S7-1200.
