2. Module type
This parameter shows communication module type detected by VFD; users cannot adjust this
parameter. If this parameter is not defined, communication between the modules and VFD cannot be
established.
3. Node address
In PROFIBUS network, each device corresponds to a unique node address, you can use the node
address selection switch to define node address (switch isn’t at 0) and the parameter is only used to
display the node address.
If node address selection switch is 0, this parameter can define node address. The user cannot adjust
the parameter by themselves and the parameter is only used to display the node address.
4. GSD file
In PROFIBUS network, each PROFIBUS subsidiary station needs GSD file "device description
document" which used to describe the characteristics of PROFIBUS-DP devices. GSD file contains all
defined parameters, including baud rate, information length, amount of input/output data, meaning of
diagnostic data.
A CD-ROM will be offered in which contains GSD file (extension name is .gsd) for fieldbus adapter.
Users can copy GSD file to relevant subdirectory of configuration tools, please refer to relevant
system configuration software instructions to know specific operations and PROFIBUS system
configuration.
A.2.8 PROFIBUS-DP communication
1. PROFIBUS-DP
PROFIBUS-DP is a distributed I/O system, which enables master machine to use a large number of
peripheral modules and field devices. Data transmission shows cycle: master machine read input
information from subsidiary machine then give feedback signal. EC-TX-103 communication card
supports PROFIBUS-DP protocol.
