Configuring Automatic Firmware Updates for EtherCAT Slaves
Functional Enhancement:
The parameter set for the Lenze c520, c550, and c750 controllers has been expanded to include parameter 0x5820:001. This parameter has three selectable values that can be used to configure whether firmware is transferred to the EtherCAT slaves connected to the EtherCAT master.
Included in which products? c520 controller, version 1.5 and later c550 controllers, version 1.5 and later c750 controller, version 1.5 and later
Application: The controller’s EtherCAT master compares the firmware major version (i.e., the first digit of the firmware version number) of the connected EtherCAT Slaves (i550, i700) with the firmware major versions configured in the PLC project. Depending on parameter 0x5820:001, the EtherCAT master behaves as follows:
0: Disabled
The controller does
not perform a firmware download, but instead immediately starts the
parameter set download to the EtherCAT slaves. If this is successful,
it sets the EtherCAT bus to operational status.
1: Enabled. Slave Main Version = Configured Version
The
controller performs a firmware download if the
firmware version of the respective EtherCAT slave differs from the one
configured in the PLC project, but their firmware major versions are the same
.
After the firmware download, the parameter set download to the
EtherCAT slave begins. If this is successful, the controller sets the
EtherCAT bus to the operational status.
If the
major version of the EtherCAT slave differs from the configured firmware major version,
the EtherCAT bus does not switch to the
operational status.
2:
Enabled. Slave Main Version > Configured Version (default setting)
If the firmware major version
of the EtherCAT slave is higher than the major version configured in the PLC project,
the controller does not perform a firmware download,
but instead starts the parameter set download to the EtherCAT slaves. If
this is successful, it sets the EtherCAT bus to
operational status.
If the
firmware version of the respective EtherCAT slave differs from the one
configured in the PLC project, but their firmware major versions are the same,
the controller performs a firmware download. After the
firmware download, the parameter set download to the EtherCAT slaves begins.
If this is successful, the controller sets the EtherCAT bus to
operational status.
If the
EtherCAT slave’s firmware major version is lower than the configured
major version, the EtherCAT bus does not transition to the operational status.
