Version: 2.5
Note
SysTime
The value DcSysTime of the terminal is to be used with care and should serve only as a
coarse indication as to which time zone (order of magnitude: +/-1 task cycle) the Distributed
Clocks system is currently in. The reason is that the local time in the terminal is only deter-
mined once per macro cycle, without specification of the exact time.
It is more appropriate to use an EL2258 with other EtherCAT slaves that generate a time-
stamp based on ambient influences, such as the EL1252.
Alternatively, functions can also be called at NC/PLC runtime that immediately return the
current DC time, e.g. F_GetCurDcTickTime. Refer to the notes on the TwinCAT time
sources in the
EtherCAT system documentation
.
Note
SysTime 32/64 bit
The PDO SysTime is filled as follows:
- in "CompatibleModus" the 64 bit variable is filled with the full 64 bit distributed clock time
- in "MultiTimeStamp Modus" the 64 bit variable is only filled with the lower 32 bit, since this
is also the time width of the time stamps.

Object description – specific objects
Note
EtherCAT XML Device Description
The display matches that of the CoE objects from the EtherCAT XML Device Description.
We recommend downloading the latest XML file from the download area of the
Beckhoff
website
and installing it according to installation instructions.
Note
Parameterization via the CoE list (CAN over EtherCAT)
The terminal is parameterized via the CoE - Online tab (double-click on the respective ob-
ject) or via the Process Data tab (allocation of PDOs). Please note the following general
CoE information when using/manipulating the
CoE parameters [
}

:
- Keep a startup list if components have to be replaced
- Differentiation between online/offline dictionary, existence of current XML description
- Use "CoE reload" for resetting changes
