CP 1616 onboard communications processor
8.5.5.1
CP 1616 on-board allows you to connect IPCs to Industrial Ethernet.
The basic characteristics of the PCS 1616 onboard are:
● Optimized for PROFINET IO
● Enhanced Real Time Ethernet Controller 400 = ERTEC 400
● The connectors are designed for 10BaseT and 100BaseTX.
● Data transfer rates of 10 and 100 Mbps in full/half duplex mode are supported.
● The handshake is performed automatically (auto negotiation).
● Autocrossing
● Automatic hardware detection
● Integrated 3-port real-time switch
The switch function of the 3-port real-time switch is maintained in the following cases:
● Restart (Windows Restart)
● Reset (using the shortcut <Ctrl-Alt-Del)
The switch function is interrupted in the following cases:
● Shutting down with Windows command
● Activating the on/off switch
● Shutting down with power switch (on/off switch).
Terminal devices or other network components can be connected to the three RJ45 sockets
that lead to the integrated real-time switch. The CP 1616 is connected to the LAN (Local
Area Network) via one of the three RJ45 sockets of the device.
Typical Communication Partners
CP 1616 onboard as an IO controller
The following diagram shows a typical application: CP 1616 onboard as PROFINET IO
controller on the IO controller layer.
The IO base controller user program runs on the PC. This program accesses the functions of
the IO base user program interface.
Data traffic is routed via the communication processor to several SIMATIC S7 PROFINET IO
devices, ET 200S over Industrial Ethernet.
