Parameters
EMCY trigger
CX1500-M510, CX1500-B510
Explanation
The emergency trigger byte contains the code for the particular error
that has triggered the emergency telegram. If an error has been
rectified, an emergency telegram with the error code 0x0000 is sent,
and the emergency trigger contains the description of the error that has
been corrected. Errors that are still current are signaled here in the bit
fields. Once the Bus Coupler is free of errors, it sends an emergency
telegram containing zeros everywhere other than in the emergency
trigger.

Product overview
CAN warning limit exceeded (too
many error frames)
CAN bus OFF state has been
reached. Since the coupler can no
longer send an emergency
telegram, an emergency telegram
with trigger 0x40 is sent when the
bus leaves the "off" state (a new
CAN controller initialization).
Transmit queue overrun: CAN
messages are being lost
Transmit queue overrun: CAN
messages are being lost
Incorrect PDO length
parameterized (check mapping).
Info 0: parameterized (expected )
PDO length in bytes
Info 1: current PDO length (results
from the added lengths of the
mapped objects)
Sync delayed (time-out after
communication cycle period, index
0x1006) or failed
Guarding or heartbeat delayed
(timeout following guard time x
lifetime factor, or following
consumer heartbeat time) or failed.
Altered HW configuration. The
inserted terminals or the
composition of the extension
modules has been changed since
the last save.
Event timer timeout: RxPDO not
received in time
Logical Tx queue overrun: SYNC
interval too short.
The coupler could not deliver all
the TxPDOs before the following
SYNC telegram. The TxPDOs are
then, for instance, delivered in
every second SYNC interval.
Remedy: Lengthen the SYNC
interval or raise the transmission
type. In some cases it may be
appropriate to reduce the I/O count
at this bus station (e.g. by moving I/
Os to the neighboring station)
Unsupported terminal plugged in
(BK5110 or LC5100) Info 1:
terminal number (1...64)
EEPROM error; an error occurred
when saving the configuration in
the EEPROM
K-Bus error
