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.

Visualisation: VISU_L_ETC_GetEmergency

Inputs (VAR_INPUT)

 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.

Identifier/data type Meaning/possible settings
