Profibus termination:
Depending on the position of the IRS slave on the bus, you will have to set the two jumpers, as
shown on the following diagram, to terminate the bus using the right impedance. In that case,
the wires between the MPU and the remaining unused connector should be unplugged.
The Jumpers are not set – The bus is not terminated
The Jumpers are set – The bus is terminated
As an alternative, a bus terminator can be plugged outside of the cabinet. In that case, the wires
may stay plugged, but the jumpers on the MPU shouldn’t be set.
Profibus ID:
The Profibus ID is set using the two wheels on the left of the MPU:
The PROFIBUS_DP address is displayed in a hexadecimal
format.
PFBaddr = (SW1value * 16) + SW2value
Example:
SW1
PFBaddr = (1 * 16) + 5
PFBaddr = 21
SW2
The addresses between 1 and 125 are available for the slaves.
NOTE: The address is read during the boot. So, after change to the Profibus address, one
has to turn off/on the 24 DC supply before using it.
Selecting the Overload protection mode :
For version WO20 and above, the integrated overload and shortcut protection module can be
deactivated. This deactivation may be necessary when the EMC compliance of the electrical supply in
the factory running the blow molding machine can not be achieved and when EMC filters can not be
installed on the machine. In this case the overload detection system can be affected or biased by
external perturbations and must be deactivated.
