7.1 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.
7.2 EtherCAT AL Status Codes
For detailed information please refer to the EtherCAT system description.
7.3 Firmware compatibility
The EK110x and EK15xx Couplers have no firmware.
7.4 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.
