PROFIBUS address
You can set the module's PROFIBUS address either using the
rotary switches or via the PROFIBUS-DP network. A value
between 1 and 99 (default 99) is possible using the rotary
switches, via the PROFIBUS-DP network you can choose a
value between 1 and 126.
The address set will be adopted during switching
on the power supply. For a change the power sup-
ply has to be interrupted temporarily.

Rotary switches on the module
▶ Open the clear cover (crosshead srewdriver 2mm).
▶ Set the address using the rotary switches (decade left,
unit position right).
▶ Close the clear cover.
The address set will be adopted during the next switch-on of
the power supply.
Changing the address
▶ Set the new address as described above.
▶ Interrupt the power supply temporarily.
The new address set will be adopted during the next switch-
on of the power supply.
Setting the address via the network
Prior to this you have to set the rotary switches to "00". This
setting may not be changed during operation. You will nd a
detailed description in the manual of your respective PROFI-
BUS-DP-master.
Data transfer rate
The data transfer rate will be detected and set automatically
as soon as the module communicates with the master (auto
baud detection).
Process data and bit assignment
The PROFIBUS-DP telegram permits the transmission of
244bytes user data at maximum.
The UR67-PB-78-16DI-12-60K module can transmit two
bytes (input only).
The UR67-PB-78-16DIO-12-60K module uses, depending on
the conguration,
– 8DI/8DO: two input and two output bytes
– 16DI: two input bytes
– 16DO: two output bytes

M12 output
Byte 0 4B 4A 3B 3A 2B 2A 1B 1A

When using the UR67-PB-78-16DIO-12-60K module with
8DI/8DO conguration the channels 1 to 4 (left hand socket
row) are determined to the input bytes whereas the channels
5 to 8 (right hand socket row) are determined to the output
byte.
