Diagnostics
Message
Fig. 145: Error message during bootup – General parameter incompatibility reason
Solution
Variable alignment not complied with, secondary side doesn't match primary side
→ transmit the variable configuration online to the secondary side using Create/GetConfiguration
Message
Fig. 146: Error message during bootup – Data type does not match, length of service parameter does not
match, download pdo entries
Solution
more than 59 variables created, ADS logger message during bootup, data transmission in OP state may be
possible
→ use fewer variables OR
→ do not download the PDO configuration (then up to 255 variables are possible without error message, but
this should not be used)

Operation without primary side
The central controller of the EL669x is supplied with power from the primary side. If the EL669x is started
from the secondary side without primary voltage, the secondary side is therefore unable to change from the
INIT state. Similarly, if both sides were in operation, after a power failure on the primary side a regular status
change is no longer possible on the secondary side. The secondary side responds to associated requests
with ERROR.
For an automatic restart of the secondary bridge side, function blocks from the TcEtherCAT.lib should be
used in the secondary-side PLC in this case. The default settings of the system manager "ReInit after
ComError" and "Auto Restore States" are insufficient in this case.
The LED RUN SEC responds accordingly.
