Since the new S7-CX series behaves like a original SIMATIC® PLC, the programming tools S7 for Windows® and STEP®7 can be used. Online connections can be established via Ethernet. The S7-CX executes a program in the same manner as a hardware PLC. The program of a S7-PLC can be transferred to the S7-CX series.
As hardware platform for the S7-CX, the modular DIN rail PCs of the CX series of the Beckhoff automation GmbH is used. The fieldbus used to control the central and the distributed I/O primarily is EtherCAT (Real-Time Ethernet).
- PU functions with Step®7 or S7 for Windows® over Ethernet with the ISO on TCP (RFC1006) or the IBHLink protocol
- Online connections via PROFIBUS-DP are possible with the Beckhoff PROFIBUS Master EL6731.
Operator panels (OPs) and PU devices can be connected in the usual way to PROFIBUS-DP.
- HMI applications can connect via ISO on TCP (RFC1006), the IBHLink protocol or via the optional IBH OPC Server for the visualization PC.
- Diagnostics and HMI via Intranet/Internet with the integrated web server.
- PLC to PLC communication via the integrated Ethernet CP.
- Based on the reliable and flexible Beckhoff hardware.
- In conjunction with the Beckhoff TwinSAFE modules, safety functions (f.i. emergency stop) can be realized very easy and cost-efficient with the S7-CX315, S7-CX317 and S7-CX416 PLC.
- Using the EtherCAT technology, it is possible to integrate other fieldbus segments, as for instance PROFIBUS DP, CANOpen, AS-i, DeviceNet, ControlNet, Modbus, Fipio, CC-Link, EtherNet/IP, and SERCOS interface at any place of the EtherCAT network.
- For the operation in building automation, the bus systems LON, EIB/KNX, MP, as well as DALI are available.
- Special functions for the peripheral devices (ADS functions) can be called via integrated function blocks.
