9.5 FoE interface

The function blocks of the "FoE interface" (File over EtherCAT) allow you to transmit files between

the EtherCAT master and the EtherCAT slaves.

9.5.1 L_ETC_FoE_Read (FB)

This function block activates a file upload from the slave or from the master.

Visualisation: VISU_L_ETC_FoE_Read

Inputs (VAR_INPUT)

 Note!

For executing the function block, the EtherCAT master and the slave must be at least in

the "Pre-Operational" state.

xExecute

BOOL

A positive edge (TRUE) activates a read request (upload) of a file.

xAbort

BOOL

A positive edge (TRUE) aborts a running read request (upload).

xAbort is currently not supported in the Lenze control technology R3.x.

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).

uiDevice

UINT

EtherCAT address of the master/slave.

• The address 0 directly accesses the object directory of the EtherCAT master.

sFileName

CAA_FILENAME

File name of file to be read

• Max. 32 characters (see szFileNameLen)

• Directory structures are not supported.

szFileNameLen

CAA_SIZE

File name length

• The file name must not be longer than 32 characters.

• In the case of more than 32 characters, the ETC_E_INVALIDPARM (0x9811000B)

error is returned.

Example: "firmware.efw" corresponds to 12 characters.
