xExecute
BOOL
A positive edge (TRUE) activates a write request (download) of a file.
xAbort
BOOL
A positive edge (TRUE) aborts a running write request (download).
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 written
• 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.
dwPassWd
DWORD
Password
udiTimeout
UDINT
Timeout in milliseconds (ms)
• The value 0 is not permissible and causes the error ETC_E_INVALIDPARM
(0x9811000B).
