1.1 General
The following modules are designed for the integration of NORD frequency inverters into the SIMATIC
Manager. The description of the modules provides the programmer with a brief explanation of the use
and parameterisation of the modules. For a more detailed description of the inverter parameters,
please refer to the manual for the relevant frequency inverter.
The document is divided into a process module section and a parameter module section.
Process modules Prozess_PPOx_16 For communication with up to four 16 bit words

STW + 1 or 3 SW

ZSW + 1 or 3 IW
Prozess_PPOx_32 Specially for positioning applications with a 32 bit position
value

STW + position value (32 bit) + 1 SW (16 bit)

ZSW +. position value (32 bit) + 1 IW (16 bit)
Parameter modules PARA_PPO_... For cyclic data communication
PARA_ACYC_... For acyclic data communication
Note
The modules described here are recommendations and can be individually modified by
the customer.
For the structure of your own modules, please refer to the detailed information on NORD
parameter structures in the supplementary PROFIBUS manuals (BU 0020 or BU 0200).
ATTENTION
NORD explicitly accepts no guarantee for the function of the modules or the devices which
they control.
