The road to PROFIBUS PROFIBUS in the OSI model PROFIBS 표준은 OSI model 의 3 개 Layers 로구성된다. -application layer, -data link layer, -physical layer. 3 The road to PROFIBUS Overview of the PROFIBUS family 4
Basic Principles Transmission speed (baudrate) PROFIBUS 는 10 개의통신속도 (RS485) 를선택하여사용할수있다.. 9.6; 19.2; 45.45; 93.75; 187.5; 500; 1500; 3000; 6000; 12000 kbit/s REMARKS : * 최대케이블길이와통신속도는역의관계가성립된다. * 통신속도는같은 Bus에있는모든 Master에서똑같게지정되어야한다. * 대부분의 Slave는통신속도를자동적으로인식한다. * 경제적, 기술적사유로어떤제품들은모든통신속도를지원하지는않는다. * 오래전제품들은 45.45 kbit/s 통신속도를지원하지않는경우가있다. 5 PROFIBUS DP (part 1) GSD files 6

RS 485 and PROFIBUS DP Cable construction and wire colors The A and B are green and red : 9 RS 485 and PROFIBUS DP Cable types 아래종류의케이블은표준 PROFIBUS 케이블이사용될수없는환경에서사용할수있다. * Robust Cable * Food Cable * Underground Cable * Trailing Cable * Festoon Cable * FRNC Cable * Flexible Cable * Shipboard Cable * Hybrid Cable 10
RS 485 and PROFIBUS DP Connectors * Connector 에대한기술은별도로정의되어있지않다. 즉, 제조사의제품이 Connector 의특성을정한다. * PROFIBUS 표준에서추천하는종류 : DB9 and M12 * 제조사가표준에서정한 Connector 를선택한다면표준에따라장치되어야한다. 11 12

PROFIBUS DP (part2) Power on/ Reset DP slave state machine (1) Diagnostics Parameters Configuration Diagnostics Master 는유효하지 ( 연결되어있지 ) 않은 Slave 의 Diagnostic 을지속적으로요구한다. Slave 가 diagnostic 요구에응답을준경우에비로소 Parameter 가전송된다. Parameter 후에 Configuration 이전송된다. Configuration 후에 Master 는모든것이받아들여졌는가를확인하고자 Diagnostics 를요구한다. Slave 에모든정보가받아들여지면 Master 는지속적으로 Slave 와함께 Data Exchange 를한다.
