Remove coupler write protection (CAN representation)
In order to remove the coupler write protection, the following SDO telegrams (download requests) must thus
be sent to the coupler:
Id=0x600+Node-ID DLC=8; Data=23 00 45 00 FE AF 02 E3
Id=0x600+Node-ID DLC=8; Data=23 00 45 00 01 00 01 E3
Id=0x600+Node-ID DLC=8; Data=23 00 45 00 01 01 00 E3
An example of writing register values
After the write protection has been removed, the baud rate index for DIP switch setting 1,1 is to be set to the
value 7. This will assign a baud rate of 20 kbaud to this switch setting.
This requires the value 7 to be written into table 100, register 3. This is done with an SDO write access
(download request) to index 0x4500, sub-index 0 with the 32 bit value E4 03 00 07 (0xE4 = 0x64+0x80):
Id=0x600+Node-ID DLC=8; Data=23 00 45 00 07 00 03 E4
Identify terminals
The identifier of the coupler (or of the bus station) and of the attached Bus Terminals can be read from the
Bus Coupler's table 9. Register 0 then contains the identifier of the Bus Coupler itself, register 1 the identifier
of the first terminal and register n the identification of the n
th
terminal:

The Bus Coupler description in register number 0 contains 5120 = 0x1400 for the BK5120, 5110 = 0x13F6
for the BK5110 and 5100 = 0x13EC for the LC5100. The Fieldbus Box modules contain the identifier 510 dec
= 0x1FE in register 0.
In the case of analog and special terminals, the terminal identifier (dec) is contained in the extension module
identifier or the terminal description.
Example: if a KL3042 is plugged in as the third terminal, then register 3 contains the value 3042
dec
(0x0BE2).
The following bit identifier is used for digital terminals:
