Function
Switch for terminating
resistor
A bus line must be terminated with a terminating resistor. Note that a terminating resistor can also
be present in the connector and select the switch position accordingly. Switch up = resistor On.
Only one terminating resistor is permitted at the end of a PROFIBUS line.
Settable PROFIBUS
address
The PROFIBUS address is set using the software as follows:
A value from 0 … 125 can be set under "P-INTERFACE/P- fieldbus/P-PB/PN/Modbus/P-
PB/PN/BUS address".
If you specify the value 0, the address will be set by the hardware. In this case, set an address in
the range 0 to 99 using a screwdriver.
LED "bus diagnostics" Flashing at 1 Hz, 0.5 s On, 0.5 s Off
Error in the input/output configuration
Flashing at 2 Hz, 0.25 s On, 0.25 s Off
Error in the length of the PROFIBUS telegram
Flashing at 4 Hz, 0.12 s On, 0.12 s Off
Error when initializing PROFIBUS
Off
No bus fault

PROFINET IO
You can purchase a PROFINET board as accessory; it can also be retrofitted. This is
installed under the grey plastic cover. It is available in two versions: with Ethernet or
alternatively with fiber optic sockets.
Based on the designation on the rating plate, you can identify whether or which of these two
boards is installed.
The designation
"…
Type code
_ _ _ _ N _" means Ethernet CU (RJ45) connection and
"…
Type code
_ _ _ _ F _" means fiber optic (SCRJ) connection
(see: Order numbers / Type designations (Page 31))
Note
Risk of confusion relating to the LEDs
The "Network status" display (NS), as well as the "Module status" display (MS) comprises a
green and a red LED.
The "Link / Activity / Speed" (L/A/S) display comprises a green and a yellow LED.
In the following, the term "LED" summarizes the two LEDs in the display mentioned in the
corresponding context.
As the two LEDs are close to one another, there is a risk of confusion, especially for the
network status and module status LEDs.
