Safety instructions and behavioral rules for Class 1
laser
CAUTION
Class 1 laser product – danger of accident due to glare!
The following laser-specific behavioral rules are to be followed for the Class 1 laser prod-
ucts described in this document:
• The laser beam may not be directed toward persons, since accidents may be caused
by glare.
• Do not look into the direct or reflected beam.
• If laser radiation meets the eye, the eyes must be consciously closed and the head
turned away from the beam immediately.
• When using the laser, no optical instruments may be used to view the radiation source,
since this can lead to exposure limit values being exceeded.
• Manipulations (modifications) of the laser device are not permitted.

Firmware Update EL/ES/EM/EPxxxx
This section describes the device update for Beckhoff EtherCAT slaves from the EL/ES, EM, EK and EP
series. A firmware update should only be carried out after consultation with Beckhoff support.
Storage locations
An EtherCAT slave stores operating data in up to 3 locations:
• Depending on functionality and performance EtherCAT slaves have one or several local controllers for
processing I/O data. The corresponding program is the so-called
firmware
in *.efw format.
• In some EtherCAT slaves the EtherCAT communication may also be integrated in these controllers. In
this case the controller is usually a so-called
FPGA
chip with *.rbf firmware.
• In addition, each EtherCAT slave has a memory chip, a so-called
ESI-EEPROM
, for storing its own
device description (ESI: EtherCAT Slave Information). On power-up this description is loaded and the
EtherCAT communication is set up accordingly. The device description is available from the download
area of the Beckhoff website at (
http://www.beckhoff.de
). All ESI files are accessible there as zip files.
