10 Hardware settings via DIP switches
1: Connection to head transmitter
2: DIP switches (1 - 64, SW/HW and ADDR) for configuring the
device address
3: DIP switch (SIM = simulation mode (has no function); WRITE
LOCK = write protection; DISPL. 180° = switch (turn) the
display screen 180°)
Procedure for setting the DIP switch:
1. Open the cover of the terminal head or field housing.
2. Remove the attached display from the head transmitter.
3. Configure the DIP switch on the rear of the display accordingly. In general: switch to ON
= function enabled, switch to OFF = function disabled.
4. Fit the display onto the head transmitter in the correct position. The head transmitter
accepts the settings within one second.
5. Secure the cover back onto the terminal head or field housing.
Configuring the device address
• The address must always be configured for a PROFIBUS
®
PA device. Valid device addresses
are in the range between 0 and 125. In a PROFIBUS® PA network, each address can only be
assigned once. If an address is not configured correctly, the device is not recognized by the
master. The address 126 is used for initial commissioning and service purposes.
• All devices are delivered ex works with the address 126 and software addressing.
Following a device address change, the head transmitter must be powered up again so
that the head transmitter will adopt and save the new device address.
