Siemens PAPBH - Manual (Page 4)

Introduction
The PAPBH is a gateway that allows a Paradigm Operator Interface access to a PROFIBUS-DP Network. The Host Adapter is connected to the Operator Interface
programming port allowing data transfer with Internal Communications Blocks. The PAPBH is auto-configuring for all PROFIBUS properties such as baud rate, but
needs a Station Address configured by the Operator Interface. These are set up using the PROFIBUS Network Driver described here.
Configuration
The Station Address and Input and Output Data Container Blocks are set in the Configuration Edit dialog from the Select Communications Driver dialog.
The Station Address has a default value of 126 and must be in the range 1 to 125 for normal operation.
The Input and Output Data Container Blocks are the data buffers that the PROFIBUS Network writes data to, and reads data from. These correspond to Internal
Communications Blocks and as such these must be set up in the Communications Block Table. A maximum of 116 words may be transferred per block. Data flow is
described with respect to the PROFIBUS Network - thus Input Data is written to the PROFIBUS Network and Output Data is read from the PROFIBUS Network.
Example
This example shows the PROFIBUS Node configured as Station Address 5, Communications Block A as Input Data and Communications Block B as Output Data.
