PROFIBUS-DP 

Communication Module 

� GENERAL 

This General Specification (GS) describes PROFIBUS-DP communication functions and hardware specifications of 

the module. 

The PROFIBUS-DP Communication Module is installed in the FCN or FCN-RTU and communicates with the 

devices that have PROFIBUS-DP communication functionality. 

For details on FCN, see “FCN Autonomous Controller Hardware” (GS 34P02Q12-01E) and “FCN/FCJ Autonomous 

Controller Functions” (GS 34P02Q01-01E).For details on FCN-RTU, see “FCN-RTU Low Power Autonomous 

Controller Hardware” (GS 34P02Q13-01E) and “FCN-RTU Low Power Autonomous Controller Functions” (GS 

34P02Q02-01E). 

� FEATURES OF THE PROFIBUS-DP COMMUNICATION 

Specifications of the PROFIBUS-DP has been standardized internationally by the association of Profibus, and has 

been approved in the fieldbus international standard IEC61158 and European standard EN50170. 

PROFIBUS-DP has been used for communication with automation systems and distributed devices (remote I/O, 

inverters, etc.).

� FCN, FCN-RTU (FCN: STYLE S3 or later, FCN-RTU: STYLE S2 or later) 

FCN and FCN-RTU controls and monitors slave devices. It collects system alarms and other information from slave 

devices. Its control and calculation functions allow calculation results to be sent to slave devices. 

� PROFIBUS-DP Communication Module (NFLP121) 

The PROFIBUS-DP Communication Module is installed in the FCN or FCN-RTU system to provide for PROFIBUS-DP 

communications. It runs as a master device in PROFIBUS-DP communication. 

� Logic Designer 

Logic Designer software is used for developing control applications for the FCN and FCN-RTU. 

It is used to create, debug, and download control applications to be run on the FCN and FCN-RTU. 

� Resource Configurator (Including PROFIBUS-DP Configurator) 

Resource Configurator software is used for basic FCN and FCN-RTU setup. It is used for basic configuration (IP 

address, I/O modules, license, and etc.) of the FCN and FCN-RTU and device label definition. 

From Resource Configurator, you can run the PROFIBUS-DP Configurator software tool. 

PROFIBUS-DP configurator is used for basic configuration of the PROFIBUS-DP (transmission rate, etc.), the slave 

device configuration, and module definitions and parameter settings in the slave device. 

� SCADA software (FAST/TOOLS, VDS and etc.) 

SCADA software is used for controlling and monitoring processes. SCADA software controls and monitors slave 

devices via the FCN or FCN-RTU. 

� Slave devices 

PROFIBUS-DP slave devices have PROFIBUS-DP communication functionality and thus can exchange data with the 

FCN or FCN-RTU connected to same PROFIBUS-DP via a PROFIBUS-DP Communication Module (NFLP121).

� STARDOM PROFIBUS-DP SYSTEM MAIN FUNCTION 

The main function of a PROFIBUS-DP system is described below. 

� Communication and control functions 

The PROFIBUS-DP Communication Module (NFLP121) runs as PROFIBUS-DP master device. 

It supports two specification versions, namely, DP-V0 and DP-V1, and has the following communication and control 

functions. 

• Process data input and output: Control loops can be implemented using I/O data processing POUs for PROFIBUS- 

DP and device labels defined for I/O devices. 

• Message display: Diagnostic information detected by the PROFIBUS-DP Communication Module (NFLP121) 

or slave devices can be displayed on HMI (for operation and monitoring) as messages. Messages of the DP-V1 

specification can also be displayed for slave devices supporting the DP-V1 specification. 

• I/O module status display: Errors of the PROFIBUS-DP Communication Module (NFLP121) or other PROFIBUS-DP 

communication errors can be displayed on HMI (for operation and monitoring).
