Appendix C - Replacing FENA-xx
module with FMBT-21

Contents of this chapter

This chapter shows the configurations to replace FENA-xx with FMBT-21.

Compatibility

FMBT-21 supports automatic configuration of fieldbus settings and service
configuration. The automatic configuration can be performed when FENA-xx is replaced
with FMBT-21 and it is configured to use an Modbus/TCP or Modbus/UDP profile. In
case of other profiles (for example, Ethernet/IP), a manual configuration is needed.

Automatic configuration process

FMBT-21 reads the fieldbus configuration parameters from the drive (group A) during
the first initialization. When FMBT-21 detects a FENA-xx or Ethernet usage, FMBT-21
accepts the configuration settings read from the drive and overwrites the configuration
back to the drive.
The configuration for FENA-xx (v3.10 or later) is stored in a backup file on the drive,
for example, ACS880, v2.6 or later, ACS380/ACS580, v2.04 or later.
During the first initialization, FMBT-21 checks the backup configuration of module
type and protocol from the drive. When FMBT-21 detects that a FENA-xx or Modbus/TCP
(UDP) was used, FMBT-21 reads the backup file from the drive and extracts the service
configuration parameters configured through FENA-xx web page. The parameters
recognized by FMBT-21 (for example, ping response, IP config tool, ETH tool network)
are applied and the unrecognized parameters are ignored.
After replacing FENA-xx with FMBT-21, FMBT-21 automatically enables the configuration
lock to prevent unwanted modifications to the service configuration.
