FANUC A06B-6093-H152伺服放大器
PROFIBUS PA PROFIBUS for Process Automation PROFIBUS International（PI）PROFIBUS国际伞式组织成立于1995年。PROFIBUS用户组织e.V.（PNO）PNO是PROFIBUS制造商和用户的贸易组织，成立于1989年。冗余：一个项目（系统、设备或部件）存在一种以上的能力来执行其预期功能。通过现场总线连接到控制器的远程I/O输入/输出单元。用于PROFIBUS DP的RLM 01冗余链路模块。RLM 01将非冗余PROFIBUS从设备连接到线路冗余PROFIBUS。RS-485来自EIA（美国电子工业协会）的通信接口标准，工作电压在0V和+5V之间。RS-485比RS-232C更抗噪声，可处理更长距离的数据传输，并可驱动更多接收器

PROFIBUS
International (PI)
The international umbrella organization for PROFIBUS
founded in 1995.
PROFIBUS User
Organization e.V. (PNO)
The PNO is the trade body of manufacturers and users
for PROFIBUS founded in 1989.
Redundancy The existence of more than one capability of an item
(system, equipment or component) to perform its
intended function.
Remote I/O Input/Output units connected to a controller via a
fieldbus.
RLM 01 Redundancy Link Module for PROFIBUS DP. The
RLM 01 connects a non redundant PROFIBUS slave to
the line redundant PROFIBUS.
RS-485 A communication interface standard from EIA
(Electronics Industries Association, USA), operating on
voltages between 0V and +5V. RS-485 is more noise
resistant than RS-232C, handles data transmission over
longer distances, and can drive more receivers
