FANUC A06B-6096-H203伺服放大器模塊
PROFIBUS系列由三種類型的協(xié)議組成，每種協(xié)議用于不同的任務。當然，具有所有三種協(xié)議的設(shè)備可以通過PROFIBUS網(wǎng)絡在復雜系統(tǒng)中相互通信。三種協(xié)議類型是：PROFIBUS FMS、DP和PA。只有DP和PA兩種協(xié)議類型對過程自動化很重要。PROFIBUS DP：分散外圍設(shè)備的總線PROFIBUS DP（RS 485）負責過程自動化系統(tǒng)的控制器級與現(xiàn)場分散外圍設(shè)備之間的通信，以及通過DP Ex屏障進入危險區(qū)域的本質(zhì)安全（RS485-is）。PROFIBUS DP的一個特點是傳輸速度高達12 Mbit/s。PROFIBUS PA：過程自動化的擴展此PROFIBUS變體是為過程工業(yè)開發(fā)的。變送器和定位器的通信和電源直接通過一根雙線電纜進行處理，并符合IEC標準61158-2（也稱為MBP、MBP-LP）。1區(qū)/分區(qū)的本質(zhì)安全（EEx i）（MBP-IS）裝置
The PROFIBUS family is composed of three types of protocol, each of which is
used for different tasks. Of course, devices with all three protocols can communicate
with each other in a complex system by means of a PROFIBUS network.
The three types of protocols are: PROFIBUS FMS, DP and PA.
Only the two protocol types DP and PA are important for process automation.
PROFIBUS DP: the bus for the decentralized periphery
The PROFIBUS DP (RS 485) is responsible for communication between the
Controller level of a process automation system and the decentralized periphery in
the field, also intrinsic safety (RS485-IS) via DP-Ex barriers into hazardous area.
One feature of PROFIBUS DP is its high speed of transmission up to 12 Mbit/s.
PROFIBUS PA: extension for process automation
This PROFIBUS variant was developed for the process industry. Communication
and power supply to Transmitter and Positioners are handled direct via one 2-line
cable and correspond to IEC Standard 61158-2 (named also as MBP, MBP-LP).
