Chapter 1 Introducing the PA912 Module
6F8C1259
1.1 Functions and Characteristics of the PA912 Module
The PA912 is the module to connect the Unified Controller "nv series" and the
PROFIBUS slave device by PROFIBUS network.
The PROFIBUS was developed by Siemens AG, and has been regarded as a
global standard network.
The PROFIBUS approved by the Deutsche Industrie Norman (DIN19245) and the
European Norm (EN50170), followed by the international standard IEC-61158.
At the practical application level, the PRPFIBUS is widely used in Europe, North
America and other regions with more than 1,100 companies participating in the
users group as well as approximately 300 vendors providing about 2,000 types
of products. The PROFIBUS has three protocols, "DP", "FMS", "PA". The PA912
supports the "DP" protocol, because "DP" protocol is most widely used and has a
specification of most high speed performance, efficiency, and connected cost.
The PA912 can configure transmission paths with twisted pair cables.
Characteristics of the PA912 module
· PROFIBUS-DP DP-V0 protocol version compliance
Connected to the PROFIBUS as the master module, the PA912 can control
PROFIBUS slave I/O devices.
· Relay to TC-net I/O loop
The PA912 relays input/output data of PROFIBUS slave I/O devices to the
TC-net I/O loop. It enables high speed cyclic data transmission.
· Fast transfer
Fast data transfer is possible because PROFIBUS bus I/O data are directly
transferred with the dedicated transmission gate arrays.
· High reliability
PROFIBUS I/O data is subjected to data check and error correction based on
ECC, thus providing a highly reliable data transfer.
CAUTION
To use PA912 module as a duplexed module is
available.
Mandatory
CAUTION
For the slave I/O setting of PA912 PROFIBUS, use
the HMS PROFIBUS configurator tool, (Anybus
NetTool-PB).
