9.4 Diagnostic Interface
The "Diagnostic Interface" provides diagnostic blocks for the master and the slaves. The
L_ETC_GetErrorString function converts the internal error code into a readable string.
9.4.1 L_ETC_GetEmergency (FB)
This function block outputs CoE emergency frames which have been stored in a buffer by the I/O
driver before.

Note!
For executing the function block, the EtherCAT master and the slave must be at least in
the "Pre-Operational" state.

usiCom
USINT
EtherCAT master instance number
• In the Lenze control technology R3.x, only instance number 1 is currently
supported. usiCom has been pre-assigned with 1, so that the input can be left
open.
• A value that does not equal 1 causes the error ETC_E_INVALIDPARM
(0x9811000B).
xExecute
BOOL
A positive edge (TRUE) activates a read request of a CoE emergency frame from the
buffer.
xReset
BOOL
A positive edge (TRUE) resets the buffer and deletes all CoE emergency frames saved
until then.
