The fido5100 and fido5200 (REM switch) are programmable
IEEE 802.3 10 Mbps/100 Mbps Ethernet Internet Protocol
Version 6 (IPv6) and Internet Protocol Version 4 (IPv4) switches
that support virtually any Layer 2 or Layer 3 protocol. The
switches are personalized to support the desired protocol by
firmware that is downloaded from a host processor.
The firmware is contained in the real-time Ethernet multiprotocol
(REM) switch driver and is downloaded at power-up. The REM
switch can be ready for network data operation in less than 4 ms to
support fast startup and quick connect type network functionality.
The REM switch devices have the same signal assignments as
defined in this data sheet.
The fido5100 supports the following protocols: PROFINET real
time (RT) and isochronous real time (IRT), EtherNet/IP with
and without device level ring (DLR), Modbus TCP, and
POWERLINK.
The fido5200 supports the following protocols: EtherCAT and
all protocols defined for the fido5100.
APPLICATIONS
Industrial automation
Process control
Managed Ethernet switch
The REM switch is intended for use with a host processor.
Network operation is handled using the functions and services
provided in the REM switch driver. The host processor can
implement any protocol stack by integrating it with the REM
switch driver. An example application is shown in Figure 11.
The REM switches are available in a 144-ball chip scale package
ball grid array (CSP_BGA) package.
Note that throughout this data sheet, multifunction pins, such
as A02/ALE, are referred to either by the entire pin name or by
a single function of the pin, for example, ALE, when only that
function is relevant.
