Fast Device Replacement

Original instructions

Introduction

This service provides automatic recovery of parameters or intelligent modules connected to a sub-segment. The recovery of this information is important during the replacement of a module with another module.

This service:

supplies an IP address to a device from the name given to this station (device name)
gives a remote station the capacity to store parameters and (when required) recover them

Operation

This service requires the use of the DHCP server and the server of the BMX NOE 01x0 modules. It can manage up to 64 remote stations.

Operating principles:

initially:
- (1) The valid device obtains an IP address from the name that has been given to it (device name).
- (2) The device gives its configuration parameters to the server.
secondly: This station breaks down. It is replaced with a non-configured device of the same type, which has the same name as the station it replaces:
- (1) It then transmits a DHCP request to the server.
- (2) It receives its configuration file, which was saved first on the server.
- (3) The device restarts automatically.

NOTE: The Device Name is limited to 16 ASCII characters.

NOTE:

Schneider Electric supports FTP communication between BMX NOE 01x0 modules and the following tools:

Schneider Electric firmware upgrade utilities
Microsoft Windows command-line FTP client
FTP clients in device Web pages
FTP client access by approved devices that use the Schneider Electric FDR server service

In a programmable controller system, an I/O module interfaces directly to the sensors and actuators of the machine/process. This module is the component that mounts in an I/O base and provides electrical connections between the controller and the field devices. Normal I/O module capacities are offered in a variety of signal levels and capacities.

transparent factory Ethernet. Schneider Electric’s open automation framework based on TCP/IP.

A user defined, unique logical personal identifier for a network device. After the Ethernet communications module is configured with a valid device name, the DHCP server uses it to identify the rack at power up.

Trivial File Transfer Protocol. TFTP is a scaled-down version of FTP that uses UDP, often to initialize diskless workstations.

dynamic host configuration protocol. DHCP is a TCP/IP protocol that allows network devices (DHCP clients) to obtain their IP addresses from a DHCP server through a request to the server.
