SIMATIC S7-1200 Communication
Integrated PROFINET Interface
The new CPU-Firmware Version 2.0 of Simatic S7-1200 supports communication with Profi net IO devices as a Profi net IO controller. By means of the integrated Web-server, information can be called via the CPU and process data via a standard Web browser. Data can also be archived from the user program during runtime.
Utilizing established TCP/IP standards, the integrated PROFINET interface provided with the SIMATIC S7-1200 can be used for programming, or to communicate with HMI devices and additional controllers. As a PROFINET IO controller, SIMATIC S7-1200 now supports communication with PROFINET IO devices. The interface consists of a noise-immune RJ45 connector with auto-cross-over functionality, which supports Ethernet networks and features a data transmission rate of up to 10/100 Mbit/s.
Communication with third-party devices
Seamless integration of devices from other manufacturers is possible with the integrated PROFINET interface on the SIMATIC S7-1200. It is possible to connect and communicate with multiple third-party devices utilizing the supported open Ethernet protocols TCP/IP native and ISO on TCP.
This communication capability, which is configured with standard T-Send/T-Receive instruc-tions provided by the integrated engineering system SIMATIC STEP 7 Basic, offers you an even higher level of flexibility in designing your automation solution.
Easy communication modules
Up to 3 communication modules can be added to any of the SIMATIC S7-1200 CPUs.
The RS485 and RS232 communication modules are fit for serial, character-based point-to-point connections. The library functions USS drive protocol and Modbus RTU Master and Slave protocols are already included within the SIMATIC STEP 7 Basic engineering system.

Fast fieldbus communication via PROFIBUS – the fieldbus standard
Thanks to the recent connection between S7-1200 and the fieldbus standard PROFIBUS - the powerful network with short reaction times -, a uniform commu-nication from the field level to the control level will be made possible in the future. This is our dedicated reaction to one of the most important requirements in the segment of compact automation.
There are two new communication modules (CMs) that facilitate the connection of S7-1200 to PROFIBUS. Up to 16 field devices may be connected as DP slaves with the DP Master
CP 1243-5, as decentralized peripheral ET 200 units, for example. The S7-1200 may function as a DP slave with the CM 1242-5 and may thus be connected to any other DP master. Both modules are easily connected via the backplane bus to the left of the CPU.
Simple networking
To minimize cabling and provide maxi-mum networking flexibility, the CSM 1277 Compact Switch Module can be used to configure a uniform or mixed network - with line, tree or star topologies. The CSM 1277 is a 4-port unmanaged switch, which allows you to connect the SIMATIC S7-1200 with up to three additional devices.
Simple telecontrol applications
The new communication processor CP 1242-7 enables both monitoring and controlling of distributed S7-1200 units from a single hub - via mobile telephone networks or the Internet.

| Siemens Box IPC827C |
The Box PC SIMATIC IPC827C is a rugged and flexibly expandable control cabinet PC for machine-level applications in 24-hour continuous operation at ambient temperatures of up to 55 °C.
Flexible scaling and expansion thanks to five long slots:
- 3 x PCI,
- 1 x PCIe x4
- 1 x PCIe x16
- two CompactFlash drive slots, easily accessible from the outside
- and Solid-State Drive (SSD).
Benefits
1) Maximum performance and extremely short system response times:
- 2010 Intel Core processors (i7, i3)
- High-performance onboard HD graphics integrated in the CPU
- DDR3 storage technology
2) Very high system availability and data security due to
- Onboard RAID controller
- Solid-state drive (SSD) with 32 GB (SATA, SLC)
- ECC-RAM, work memory with error correction
4) Optional PROFIBUS or PROFINET interface with three ports for low-cost connection of distributed field devices or to interfaces with SIMATIC S7.
5) High data transmission rates and redundancy thanks to two teaming-capable Gigabit Ethernet connections
6) 4 x Hi-Speed USB 2.0 ports
7) Energy-efficient industrial PCs:
- Low power consumption due to state-of-the-art mobile technology
- Wake-on-LAN functionality for targeted booting of the IPCs from a central location via a network, e.g. after a weekend without production.
Design and functions
1) Rugged and long-term availability with the same footprint to SIMATIC IPC627C.
2) Fast diagnostics of the operating state and display of the BIOS start procedure by means of two freely programmable 7-segment displays with two additional status LEDs, e.g. for acknowledgements during data transmission.
3) Fast replacement of the CMOS battery even when installed due to externally accessible battery compartment.
4) Flexible installation in control cabinets with a high level of user friendliness due to front/portrait assembly kit and mounting brackets at ambient temperatures of up to 55 °C. All function elements and interfaces can therefore be accessed from the front.
