The key features of the PROFIBUS DP/V1 bus coupler are listed below: – DP/V1 for Class 1 and Class 2 masters– Acyclic communication with, e.g., V.24 (RS-232) modules even in the process data– Acknowledgment of peripheral faults from the user program (*)– Adaptation of the high byte/low byte format in 16 and 32-channel input and outputterminals to the control system format (*)

توضیحات محصول
The PROFIBUS DP/V1 bus coupler
1.1 The PROFIBUS system
PROFIBUS is a serial bus system that transmits data between control systems and spatially
distributed I/O terminals, to which sensors and actuators are connected.
PROFIBUS has a star/tree structure. In the PROFIBUS topology the individual bus devices
can be differentiated by means of their addressing. The communication profiles determine
how the devices transmit their data serially via the bus.
In addition to PROFIBUS
FMS (Fieldbus Message Specification) and PROFIBUS PA
(
Process Automation), PROFIBUS DP (Distributed Periphery) is the most frequently used
communication profile. PROFIBUS DP is normally a single master system, i.e., a master
controls all devices of a PROFIBUS DP system. PROFIBUS DP is designed for the easy
transmission of input and output data and specifically tailored to communication between
automation systems and distributed I/O devices
