A.1 Terminology
1) Profibus-FMS (Fieldbus Message Specification)
Solution generally used to provide communication functions in the cell level, with services
available to transmit the program file to operate the field device and its related data file, to
operate the program by remote control through the network and to manage various events which
may occur during operation of the controlled and automatized system.
2) Profibus-DP (Decentralized Peripherals)
Used to send real-time data fast between field devices. It is an example of the communication
system applied as of HS digital communication type substituted for existing 24V and 4~20Ma of
analog sign like the communication between field devices such as various sensors and actuators
installed on PLC and the field.
3) Profibus-PA (Process Automation)
Specially made for process automation with safety device built-in, which can connect sensor and
actuator with a single bus line common-used. And it provides power and data communication
function on the bus by means of 2-wire technology in compliance with the international standard
of IEC 1158-2.
4) SyCon
Application program of Profibus Network Configuration Tool used to specify the configuration
though SyCon and download the information onto the applicable module if LSIS master module
(2MLL-PMEA) is applied.
5) N Configurator
Application program of Profibus Network Configuration Tool used to specify the configuration
though N Configurator and download the information onto the applicable module if Profibus-DP
master module (2MLL-PMEB/C, MLL-PMEC) is applied.
6) GSD file
As the data sheet of electronic devices, it contains such information as maker, device name,
status of released hardware and software, Send rate available, master related standards (max.
slaves which can be connected with, upload/download option, etc.) and slave related standards
(number and type of I/O channels, diagnosis test specification and available module information
modular equipment is provided for).
7) Broadcast communication
Used to send the message whose operation station is not recognized to all the stations (Master,
Slaves).
