FDR (Fast Device Replacement) service

The Fast Device Replacement service uses standard address management

technologies (BOOTP, DHCP) and the TFTP (Trivial File Transfer Protocol) le

management service, with the aim of simplifying maintenance of Ethernet devices.

It is used to replace a device with a new device that will be detected, recongured,

and automatically restarted by the system.

The main steps in replacement are:

1 The device to be replaced is identied.

2 Another similar device is taken from the maintenance store, precongured with

the Device name for the existing device, then reinstalled on the network.

Depending on the device, addressing can be performed using rotary selector

switches (as for Modicon STB distributed I/O or Modicon OTB for example) or can

be given using the keypad integrated in the device (as for Altivar variable speed

drives for example).

3 The FDR server detects the new device, allocates it an IP address, and transfers

the conguration parameters to it.

4 The replacement device checks that all these parameters are indeed compatible

with its own characteristics and switches to operational mode.

The FDR server can be:

v A Modicon M340 Ethernet network module, BMXNOC0401

v A Modicon M580 Ethernet network module, BMXNOC0402 (1)

v A Modicon Premium Ethernet module, TSXETC101

v A Modicon Quantum PLC Ethernet module, 140NOC77101, 140NOC78000,

140NOC78100

v A Modicon Premium CPU with integrated Ethernet port, TSXP57ppppM

v A Modicon Quantum CPU with integrated Ethernet port, 140CPU65150/60,

140CPU65260

(1) The BMXNOC0402 communication module will be replaced by the BMENOC03p1 modules

during the 2nd quarter of 2014.
