Commissioning - Beckhoff EL922 Series Documentation

Commissioning

7 Commissioning
The EL922x is an EtherCAT Terminal with electronic overcurrent protection function. The overcurrent
protection function is available at all times, i.e. as soon as the input voltage has been applied, the
overcurrent protection function is active (after a successful initialization run), regardless of whether EtherCAT
is present or not. The EL922x can therefore also be operated in stand-alone mode, without EtherCAT. This
function enables applications where Industrial PCs, Embedded PCs or couplers with 24 V DC can be
supplied and protected, which then start EtherCAT later.
Commissioning for the first time
Before the first start-up, please check the wiring [} 55] and make sure that it has been carried out
correctly.
After the outputs have been switched on for the first time, they may trigger immediately and the
push-button LED may light up red. Check the set rated current.
Ensure that the power supply is high enough to ensure a safe voltage supply even in the event of a
fault. Power supplies that are dimensioned too small may not only result in a voltage dip in the
event of a fault, but may also lead to frequent or unintentional switching on and off. This could also
lead to the destruction of the electronics.
Check the process data [} 106] (hardware protection) and the Diag messages [} 151] for warnings
that could indicate a wiring error. Also check the Ready LED and the Button LEDs for flickering. The
terminal must not be operated in such a condition as this could destroy the electronics.
When commissioning for the first time without changing the parameters, the terminals are set to the factory
settings.

Lock settings with password protection
It is possible to use object 0xF009 [} 122] (password protection, data type UINT32) to protect user
parameter data from accidental access. The password protection prevents accidental overwriting of
the parameters, for example. The protection is enabled with password 0x12345678 and remains ac-
tive until it is disabled with the password 0x11223344. Object 0xF009 also indicates whether pass-
word protection is enabled or disabled. Protection is enabled if the object has the value "1" and dis-
abled if the value of the object is "0". If protection is enabled, write access to objects 0x80n0 [} 115]
and 0x80n1 [} 115] is not possible, and the parameters are retained. This also applies if the factory
settings of the terminal are to be restored via object 0x1011 [} 115] or via the LED buttons on the
device. When the terminal is reset, e.g. by de-energizing it, the protection remains enabled. The
password protection is noted in the terminal until it is disabled.
