Information!
When this command is used, the Electronic-Key must be in the Electronic-Key adapter, and must be
removed from within the operating distance only after the reply message has been received.
As the serial number of the Electronic-Key cannot be written, the start address for the data to be written
is limited to byte no. 0 to byte no. 112.
Output area of the PROFINET CPU
Byte no. Description Function
0 Command byte (see below)
1 Start address
Defines first byte in the memory of the Electronic-Key that is written
on setting bit no. 0 in the command byte. Start address user data:
Byte no. 0, 4, 8 …
112.
Defines the number of bytes in the memory of the Electronic-Key that
are written on setting bit no. 0 in the command byte. Number of bytes
of user data: 4, 8, 12 …
116 bytes.
2 Number of bytes
3 Not used
4
If bit no. 0 in the command byte is set to 1, the content of these bytes
is written to the Electronic-Key starting from the start address
defined.

Command byte
Bit no. Description (active with bit = 1) Function
0 Write Electronic-Key
After setting this bit the content of "Transmit data" is written to the
Electronic-Key inserted, starting at the "Start address" with the length
"Number of bytes". On the completion of the write process, bit no. 6
in the status byte in the input area of the CPU is set. Bit no. 0 in the
command byte in the output area of the CPU must then be set to 0
so that a new write process can be started.
